Introduction
Sending email doesn't have to be complicated. Laravel provides a clean, simple email API powered by the popular Symfony Mailer component. Laravel and Symfony Mailer provide drivers for sending email via SMTP, Mailgun, Postmark, Resend, Amazon SES, and sendmail, allowing you to quickly get started sending mail through a local or cloud based service of your choice.
Configuration
Laravel's email services may be configured via your application's config/mail.php configuration file. Each mailer configured within this file may have its own unique configuration and even its own unique "transport", allowing your application to use different email services to send certain email messages. For example, your application might use Postmark to send transactional emails while using Amazon SES to send bulk emails.
Within your mail configuration file, you will find a mailers configuration array. This array contains a sample configuration entry for each of the major mail drivers / transports supported by Laravel, while the default configuration value determines which mailer will be used by default when your application needs to send an email message.
Driver / Transport Prerequisites
The API based drivers such as Mailgun, Postmark, Resend, and MailerSend are often simpler and faster than sending mail via SMTP servers. Whenever possible, we recommend that you use one of these drivers.
Mailgun Driver
To use the Mailgun driver, install Symfony's Mailgun Mailer transport via Composer:
composer require symfony/mailgun-mailer symfony/http-clientNext, you will need to make two changes in your application's config/mail.php configuration file. First, set your default mailer to mailgun:
'default' => env('MAIL_MAILER', 'mailgun'),Second, add the following configuration array to your array of mailers:
'mailgun' => [
'transport' => 'mailgun',
// 'client' => [
// 'timeout' => 5,
// ],
],After configuring your application's default mailer, add the following options to your config/services.php configuration file:
'mailgun' => [
'domain' => env('MAILGUN_DOMAIN'),
'secret' => env('MAILGUN_SECRET'),
'endpoint' => env('MAILGUN_ENDPOINT', 'api.mailgun.net'),
'scheme' => 'https',
],If you are not using the United States Mailgun region, you may define your region's endpoint in the services configuration file:
'mailgun' => [
'domain' => env('MAILGUN_DOMAIN'),
'secret' => env('MAILGUN_SECRET'),
'endpoint' => env('MAILGUN_ENDPOINT', 'api.eu.mailgun.net'),
'scheme' => 'https',
],Postmark 驱动
要使用 Postmark 驱动，需要通过 Composer 安装 Symfony 的 Postmark Mailer 传输包：
composer require symfony/postmark-mailer symfony/http-client接下来，在应用程序的 config/mail.php 配置文件中将 default 选项设置为 postmark。配置完默认邮件发送器后，请确保 config/services.php 配置文件中包含以下选项：
'postmark' => [
'token' => env('POSTMARK_TOKEN'),
],如果你想为特定邮件发送器指定 Postmark 消息流，可以在邮件发送器的配置数组中添加 message_stream_id 配置选项。该配置数组位于应用程序的 config/mail.php 配置文件中：
'postmark' => [
'transport' => 'postmark',
'message_stream_id' => env('POSTMARK_MESSAGE_STREAM_ID'),
// 'client' => [
// 'timeout' => 5,
// ],
],这样你还可以设置多个使用不同消息流的 Postmark 邮件发送器。
Resend 驱动
要使用 Resend 驱动，需要通过 Composer 安装 Resend 的 PHP SDK：
composer require resend/resend-php接下来，在应用程序的 config/mail.php 配置文件中将 default 选项设置为 resend 。配置完默认邮件发送器后，请确保 config/services.php 配置文件中包含以下选项：
'resend' => [
'key' => env('RESEND_KEY'),
],SES 驱动
要使用 Amazon SES 驱动，首先需要安装 Amazon AWS SDK for PHP。你可以通过 Composer 包管理器安装这个库：
composer require aws/aws-sdk-php接下来，在 config/mail.php 配置文件中将 default 选项设置为 ses ，并确保 config/services.php 配置文件中包含以下选项：
'ses' => [
'key' => env('AWS_ACCESS_KEY_ID'),
'secret' => env('AWS_SECRET_ACCESS_KEY'),
'region' => env('AWS_DEFAULT_REGION', 'us-east-1'),
],
要使用 AWS 临时凭证 通过会话令牌进行身份验证，可以在应用程序的 SES 配置中添加 token 键：
'ses' => [
'key' => env('AWS_ACCESS_KEY_ID'),
'secret' => env('AWS_SECRET_ACCESS_KEY'),
'region' => env('AWS_DEFAULT_REGION', 'us-east-1'),
'token' => env('AWS_SESSION_TOKEN'),
],若要使用 SES 的 订阅管理功能，可以在邮件消息的 headers 方法返回的数组中包含 X-Ses-List-Management-Options 头信息：
/**
* Get the message headers.
*/
public function headers(): Headers
{
return new Headers(
text: [
'X-Ses-List-Management-Options' => 'contactListName=MyContactList;topicName=MyTopic',
],
);
}如果需要定义 Laravel 在发送邮件时应传递给 AWS SDK SendEmail 方法的 额外选项 ，可以在 ses 配置中定义 options 数组：
'ses' => [
'key' => env('AWS_ACCESS_KEY_ID'),
'secret' => env('AWS_SECRET_ACCESS_KEY'),
'region' => env('AWS_DEFAULT_REGION', 'us-east-1'),
'options' => [
'ConfigurationSetName' => 'MyConfigurationSet',
'EmailTags' => [
['Name' => 'foo', 'Value' => 'bar'],
],
],
],MailerSend 驱动
MailerSend作为一款事务性邮件和短信服务，为 Laravel 维护了专门的 API 邮件驱动包。可以通过 Composer 安装该驱动包：
composer require mailersend/laravel-driver安装完成后，在应用程序的 .env 文件中添加 MAILERSEND_API_KEY 环境变量。同时需要将 MAIL_MAILER 环境变量定义为 mailersend:
MAIL_MAILER=mailersend
MAIL_FROM_ADDRESS=app@yourdomain.com
MAIL_FROM_NAME="App Name"
MAILERSEND_API_KEY=your-api-key最后，在应用程序的 config/mail.php 配置文件的 mailers 数组中添加 MailerSend 配置：
'mailersend' => [
'transport' => 'mailersend',
],要了解更多关于 MailerSend 的信息，包括如何使用托管模板，请参阅 MailerSend 驱动文件。
故障转移配置
当您配置的外部邮件服务不可用时，定义备用邮件发送配置会非常有用。要实现这一点，您应该在应用程序的 mail 配置文件中定义一个使用 failover 传输的邮件发送器。 failover 邮件发送器的配置数组应包含一个 mailers 数组，指定在主要驱动不可用时按顺序尝试的备用邮件发送器：
'mailers' => [
'failover' => [
'transport' => 'failover',
'mailers' => [
'postmark',
'mailgun',
'sendmail',
],
],
// ...
],定义故障转移邮件发送器后，您应该将其设置为应用程序的默认邮件发送器，方法是在 mail 配置文件的 default 配置键中指定其名称：
'default' => env('MAIL_MAILER', 'failover'),轮询配置
roundrobin 传输允许您将邮件发送工作负载分配到多个邮件发送器上。要开始使用，首先在应用程序的 mail 配置文件中定义一个使用 roundrobin 传输的邮件发送器。 roundrobin 邮件发送器的配置数组应包含一个 mailers 数组，指定用于发送邮件的邮件发送器：
'mailers' => [
'roundrobin' => [
'transport' => 'roundrobin',
'mailers' => [
'ses',
'postmark',
],
],
// ...
],Once your round robin mailer has been defined, you should set this mailer as the default mailer used by your application by specifying its name as the value of the default configuration key within your application's mail configuration file:
'default' => env('MAIL_MAILER', 'roundrobin'),The round robin transport selects a random mailer from the list of configured mailers and then switches to the next available mailer for each subsequent email. In contrast to failover transport, which helps to achieve high availability, the roundrobin transport provides load balancing.
Generating Mailables
When building Laravel applications, each type of email sent by your application is represented as a "mailable" class. These classes are stored in the app/Mail directory. Don't worry if you don't see this directory in your application, since it will be generated for you when you create your first mailable class using the make:mail Artisan command:
php artisan make:mail OrderShippedWriting Mailables
Once you have generated a mailable class, open it up so we can explore its contents. Mailable class configuration is done in several methods, including the envelope, content, and attachments methods.
The envelope method returns an Illuminate\Mail\Mailables\Envelope object that defines the subject and, sometimes, the recipients of the message. The content method returns an Illuminate\Mail\Mailables\Content object that defines the Blade template that will be used to generate the message content.
Configuring the Sender
Using the Envelope
First, let's explore configuring the sender of the email. Or, in other words, who the email is going to be "from". There are two ways to configure the sender. First, you may specify the "from" address on your message's envelope:
use Illuminate\Mail\Mailables\Address;
use Illuminate\Mail\Mailables\Envelope;
/**
* Get the message envelope.
*/
public function envelope(): Envelope
{
return new Envelope(
from: new Address('jeffrey@example.com', 'Jeffrey Way'),
subject: 'Order Shipped',
);
}If you would like, you may also specify a replyTo address:
return new Envelope(
from: new Address('jeffrey@example.com', 'Jeffrey Way'),
replyTo: [
new Address('taylor@example.com', 'Taylor Otwell'),
],
subject: 'Order Shipped',
);Using a Global from Address
However, if your application uses the same "from" address for all of its emails, it can become cumbersome to add it to each mailable class you generate. Instead, you may specify a global "from" address in your config/mail.php configuration file. This address will be used if no other "from" address is specified within the mailable class:
'from' => [
'address' => env('MAIL_FROM_ADDRESS', 'hello@example.com'),
'name' => env('MAIL_FROM_NAME', 'Example'),
],In addition, you may define a global "reply_to" address within your config/mail.php configuration file:
'reply_to' => ['address' => 'example@example.com', 'name' => 'App Name'],Configuring the View
Within a mailable class's content method, you may define the view, or which template should be used when rendering the email's contents. Since each email typically uses a Blade template to render its contents, you have the full power and convenience of the Blade templating engine when building your email's HTML:
/**
* Get the message content definition.
*/
public function content(): Content
{
return new Content(
view: 'mail.orders.shipped',
);
}[!NOTE]
You may wish to create aresources/views/emailsdirectory to house all of your email templates; however, you are free to place them wherever you wish within yourresources/viewsdirectory.
Plain Text Emails
If you would like to define a plain-text version of your email, you may specify the plain-text template when creating the message's Content definition. Like the view parameter, the text parameter should be a template name which will be used to render the contents of the email. You are free to define both an HTML and plain-text version of your message:
/**
* Get the message content definition.
*/
public function content(): Content
{
return new Content(
view: 'mail.orders.shipped',
text: 'mail.orders.shipped-text'
);
}For clarity, the html parameter may be used as an alias of the view parameter:
return new Content(
html: 'mail.orders.shipped',
text: 'mail.orders.shipped-text'
);View Data
Via Public Properties
Typically, you will want to pass some data to your view that you can utilize when rendering the email's HTML. There are two ways you may make data available to your view. First, any public property defined on your mailable class will automatically be made available to the view. So, for example, you may pass data into your mailable class's constructor and set that data to public properties defined on the class:
<?php
namespace App\Mail;
use App\Models\Order;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Mail\Mailables\Content;
use Illuminate\Queue\SerializesModels;
class OrderShipped extends Mailable
{
use Queueable, SerializesModels;
/**
* Create a new message instance.
*/
public function __construct(
public Order $order,
) {}
/**
* Get the message content definition.
*/
public function content(): Content
{
return new Content(
view: 'mail.orders.shipped',
);
}
}一旦数据被设置为公共属性，它将自动在您的视图中可用，因此您可以像访问Blade模板中的任何其他数据一样访问它：
<div>
Price: {{ $order->price }}
</div>通过 with 参数传递:
如果您想在将电子邮件数据发送到模板之前自定义其格式，您可以通过 Content 定义的 with 参数手动将数据传递给视图。通常，您仍将通过mailable类的构造函数传递数据；但是，您应该将此数据设置为 protected 或 private 属性，这样数据就不会自动提供给模板：
<?php
namespace App\Mail;
use App\Models\Order;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Mail\Mailables\Content;
use Illuminate\Queue\SerializesModels;
class OrderShipped extends Mailable
{
use Queueable, SerializesModels;
/**
* Create a new message instance.
*/
public function __construct(
protected Order $order,
) {}
/**
* Get the message content definition.
*/
public function content(): Content
{
return new Content(
view: 'mail.orders.shipped',
with: [
'orderName' => $this->order->name,
'orderPrice' => $this->order->price,
],
);
}
}数据通过 with 方法传递后，会自动在视图中可用，您可以像访问Blade模板中的其他数据一样访问它：
<div>
Price: {{ $orderPrice }}
</div>附件
要为邮件添加附件，您需要在消息的 attachments 方法返回的数组中添加附件。首先，您可以通过 Attachment 类提供的 fromPath 方法添加文件路径来附加文件：
use Illuminate\Mail\Mailables\Attachment;
/**
* Get the attachments for the message.
*
* @return array<int, \Illuminate\Mail\Mailables\Attachment>
*/
public function attachments(): array
{
return [
Attachment::fromPath('/path/to/file'),
];
}为邮件添加附件时，您还可以通过 as 和 withMime 方法分别指定附件的显示名称和MIME类型：
/**
* Get the attachments for the message.
*
* @return array<int, \Illuminate\Mail\Mailables\Attachment>
*/
public function attachments(): array
{
return [
Attachment::fromPath('/path/to/file')
->as('name.pdf')
->withMime('application/pdf'),
];
}从存储磁盘附加文件
如果文件已存储在某个 文件系统磁盘上，可以使用 fromStorage 方法附加：
/**
* Get the attachments for the message.
*
* @return array<int, \Illuminate\Mail\Mailables\Attachment>
*/
public function attachments(): array
{
return [
Attachment::fromStorage('/path/to/file'),
];
}当然，您也可以指定附件的名称和MIME类型：
/**
* Get the attachments for the message.
*
* @return array<int, \Illuminate\Mail\Mailables\Attachment>
*/
public function attachments(): array
{
return [
Attachment::fromStorage('/path/to/file')
->as('name.pdf')
->withMime('application/pdf'),
];
}如需使用非默认存储磁盘，可使用 fromStorageDisk 方法：
/**
* Get the attachments for the message.
*
* @return array<int, \Illuminate\Mail\Mailables\Attachment>
*/
public function attachments(): array
{
return [
Attachment::fromStorageDisk('s3', '/path/to/file')
->as('name.pdf')
->withMime('application/pdf'),
];
}原始数据附件
fromData 方法允许将字节字符串作为附件添加。例如，当您已在内存中生成PDF文件且不希望写入磁盘时，可以使用此方法。该方法接收一个返回原始数据的闭包，以及附件名称：
/**
* Get the attachments for the message.
*
* @return array<int, \Illuminate\Mail\Mailables\Attachment>
*/
public function attachments(): array
{
return [
Attachment::fromData(fn () => $this->pdf, 'Report.pdf')
->withMime('application/pdf'),
];
}Inline Attachments
Embedding inline images into your emails is typically cumbersome; however, Laravel provides a convenient way to attach images to your emails. To embed an inline image, use the embed method on the $message variable within your email template. Laravel automatically makes the $message variable available to all of your email templates, so you don't need to worry about passing it in manually:
<body>
Here is an image:
<img src="{{ $message->embed($pathToImage) }}">
</body>[!WARNING]
The$messagevariable is not available in plain-text message templates since plain-text messages do not utilize inline attachments.
Embedding Raw Data Attachments
If you already have a raw image data string you wish to embed into an email template, you may call the embedData method on the $message variable. When calling the embedData method, you will need to provide a filename that should be assigned to the embedded image:
<body>
Here is an image from raw data:
<img src="{{ $message->embedData($data, 'example-image.jpg') }}">
</body>Attachable Objects
While attaching files to messages via simple string paths is often sufficient, in many cases the attachable entities within your application are represented by classes. For example, if your application is attaching a photo to a message, your application may also have a Photo model that represents that photo. When that is the case, wouldn't it be convenient to simply pass the Photo model to the attach method? Attachable objects allow you to do just that.
To get started, implement the Illuminate\Contracts\Mail\Attachable interface on the object that will be attachable to messages. This interface dictates that your class defines a toMailAttachment method that returns an Illuminate\Mail\Attachment instance:
<?php
namespace App\Models;
use Illuminate\Contracts\Mail\Attachable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Mail\Attachment;
class Photo extends Model implements Attachable
{
/**
* Get the attachable representation of the model.
*/
public function toMailAttachment(): Attachment
{
return Attachment::fromPath('/path/to/file');
}
}Once you have defined your attachable object, you may return an instance of that object from the attachments method when building an email message:
/**
* Get the attachments for the message.
*
* @return array<int, \Illuminate\Mail\Mailables\Attachment>
*/
public function attachments(): array
{
return [$this->photo];
}Of course, attachment data may be stored on a remote file storage service such as Amazon S3. So, Laravel also allows you to generate attachment instances from data that is stored on one of your application's filesystem disks:
// Create an attachment from a file on your default disk...
return Attachment::fromStorage($this->path);
// Create an attachment from a file on a specific disk...
return Attachment::fromStorageDisk('backblaze', $this->path);In addition, you may create attachment instances via data that you have in memory. To accomplish this, provide a closure to the fromData method. The closure should return the raw data that represents the attachment:
return Attachment::fromData(fn () => $this->content, 'Photo Name');Laravel also provides additional methods that you may use to customize your attachments. For example, you may use the as and withMime methods to customize the file's name and MIME type:
return Attachment::fromPath('/path/to/file')
->as('Photo Name')
->withMime('image/jpeg');Headers
Sometimes you may need to attach additional headers to the outgoing message. For instance, you may need to set a custom Message-Id or other arbitrary text headers.
To accomplish this, define a headers method on your mailable. The headers method should return an Illuminate\Mail\Mailables\Headers instance. This class accepts messageId, references, and text parameters. Of course, you may provide only the parameters you need for your particular message:
use Illuminate\Mail\Mailables\Headers;
/**
* Get the message headers.
*/
public function headers(): Headers
{
return new Headers(
messageId: 'custom-message-id@example.com',
references: ['previous-message@example.com'],
text: [
'X-Custom-Header' => 'Custom Value',
],
);
}Tags and Metadata
Some third-party email providers such as Mailgun and Postmark support message "tags" and "metadata", which may be used to group and track emails sent by your application. You may add tags and metadata to an email message via your Envelope definition:
use Illuminate\Mail\Mailables\Envelope;
/**
* Get the message envelope.
*
* @return \Illuminate\Mail\Mailables\Envelope
*/
public function envelope(): Envelope
{
return new Envelope(
subject: 'Order Shipped',
tags: ['shipment'],
metadata: [
'order_id' => $this->order->id,
],
);
}If your application is using the Mailgun driver, you may consult Mailgun's documentation for more information on tags and metadata. Likewise, the Postmark documentation may also be consulted for more information on their support for tags and metadata.
If your application is using Amazon SES to send emails, you should use the metadata method to attach SES "tags" to the message.
Customizing the Symfony Message
Laravel's mail capabilities are powered by Symfony Mailer. Laravel allows you to register custom callbacks that will be invoked with the Symfony Message instance before sending the message. This gives you an opportunity to deeply customize the message before it is sent. To accomplish this, define a using parameter on your Envelope definition:
use Illuminate\Mail\Mailables\Envelope;
use Symfony\Component\Mime\Email;
/**
* Get the message envelope.
*/
public function envelope(): Envelope
{
return new Envelope(
subject: 'Order Shipped',
using: [
function (Email $message) {
// ...
},
]
);
}Markdown Mailables
Markdown mailable messages allow you to take advantage of the pre-built templates and components of mail notifications in your mailables. Since the messages are written in Markdown, Laravel is able to render beautiful, responsive HTML templates for the messages while also automatically generating a plain-text counterpart.
Generating Markdown Mailables
To generate a mailable with a corresponding Markdown template, you may use the --markdown option of the make:mail Artisan command:
php artisan make:mail OrderShipped --markdown=mail.orders.shippedThen, when configuring the mailable Content definition within its content method, use the markdown parameter instead of the view parameter:
use Illuminate\Mail\Mailables\Content;
/**
* Get the message content definition.
*/
public function content(): Content
{
return new Content(
markdown: 'mail.orders.shipped',
with: [
'url' => $this->orderUrl,
],
);
}Writing Markdown Messages
Markdown mailables use a combination of Blade components and Markdown syntax which allow you to easily construct mail messages while leveraging Laravel's pre-built email UI components:
<x-mail::message>
# Order Shipped
Your order has been shipped!
<x-mail::button :url="$url">
View Order
</x-mail::button>
Thanks,<br>
{{ config('app.name') }}
</x-mail::message>[!NOTE]
Do not use excess indentation when writing Markdown emails. Per Markdown standards, Markdown parsers will render indented content as code blocks.
Button Component
The button component renders a centered button link. The component accepts two arguments, a url and an optional color. Supported colors are primary, success, and error. You may add as many button components to a message as you wish:
<x-mail::button :url="$url" color="success">
View Order
</x-mail::button>Panel Component
The panel component renders the given block of text in a panel that has a slightly different background color than the rest of the message. This allows you to draw attention to a given block of text:
<x-mail::panel>
This is the panel content.
</x-mail::panel>Table Component
The table component allows you to transform a Markdown table into an HTML table. The component accepts the Markdown table as its content. Table column alignment is supported using the default Markdown table alignment syntax:
<x-mail::table>
| Laravel | Table | Example |
| ------------- | :-----------: | ------------: |
| Col 2 is | Centered | $10 |
| Col 3 is | Right-Aligned | $20 |
</x-mail::table>Customizing the Components
You may export all of the Markdown mail components to your own application for customization. To export the components, use the vendor:publish Artisan command to publish the laravel-mail asset tag:
php artisan vendor:publish --tag=laravel-mailThis command will publish the Markdown mail components to the resources/views/vendor/mail directory. The mail directory will contain an html and a text directory, each containing their respective representations of every available component. You are free to customize these components however you like.
Customizing the CSS
After exporting the components, the resources/views/vendor/mail/html/themes directory will contain a default.css file. You may customize the CSS in this file and your styles will automatically be converted to inline CSS styles within the HTML representations of your Markdown mail messages.
If you would like to build an entirely new theme for Laravel's Markdown components, you may place a CSS file within the html/themes directory. After naming and saving your CSS file, update the theme option of your application's config/mail.php configuration file to match the name of your new theme.
To customize the theme for an individual mailable, you may set the $theme property of the mailable class to the name of the theme that should be used when sending that mailable.
Sending Mail
To send a message, use the to method on the Mail facade. The to method accepts an email address, a user instance, or a collection of users. If you pass an object or collection of objects, the mailer will automatically use their email and name properties when determining the email's recipients, so make sure these attributes are available on your objects. Once you have specified your recipients, you may pass an instance of your mailable class to the send method:
<?php
namespace App\Http\Controllers;
use App\Mail\OrderShipped;
use App\Models\Order;
use Illuminate\Http\RedirectResponse;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Mail;
class OrderShipmentController extends Controller
{
/**
* Ship the given order.
*/
public function store(Request $request): RedirectResponse
{
$order = Order::findOrFail($request->order_id);
// Ship the order...
Mail::to($request->user())->send(new OrderShipped($order));
return redirect('/orders');
}
}You are not limited to just specifying the "to" recipients when sending a message. You are free to set "to", "cc", and "bcc" recipients by chaining their respective methods together:
Mail::to($request->user())
->cc($moreUsers)
->bcc($evenMoreUsers)
->send(new OrderShipped($order));Looping Over Recipients
Occasionally, you may need to send a mailable to a list of recipients by iterating over an array of recipients / email addresses. However, since the to method appends email addresses to the mailable's list of recipients, each iteration through the loop will send another email to every previous recipient. Therefore, you should always re-create the mailable instance for each recipient:
foreach (['taylor@example.com', 'dries@example.com'] as $recipient) {
Mail::to($recipient)->send(new OrderShipped($order));
}Sending Mail via a Specific Mailer
By default, Laravel will send email using the mailer configured as the default mailer in your application's mail configuration file. However, you may use the mailer method to send a message using a specific mailer configuration:
Mail::mailer('postmark')
->to($request->user())
->send(new OrderShipped($order));Queueing Mail
Queueing a Mail Message
Since sending email messages can negatively impact the response time of your application, many developers choose to queue email messages for background sending. Laravel makes this easy using its built-in unified queue API. To queue a mail message, use the queue method on the Mail facade after specifying the message's recipients:
Mail::to($request->user())
->cc($moreUsers)
->bcc($evenMoreUsers)
->queue(new OrderShipped($order));This method will automatically take care of pushing a job onto the queue so the message is sent in the background. You will need to configure your queues before using this feature.
Delayed Message Queueing
If you wish to delay the delivery of a queued email message, you may use the later method. As its first argument, the later method accepts a DateTime instance indicating when the message should be sent:
Mail::to($request->user())
->cc($moreUsers)
->bcc($evenMoreUsers)
->later(now()->addMinutes(10), new OrderShipped($order));Pushing to Specific Queues
Since all mailable classes generated using the make:mail command make use of the Illuminate\Bus\Queueable trait, you may call the onQueue and onConnection methods on any mailable class instance, allowing you to specify the connection and queue name for the message:
$message = (new OrderShipped($order))
->onConnection('sqs')
->onQueue('emails');
Mail::to($request->user())
->cc($moreUsers)
->bcc($evenMoreUsers)
->queue($message);Queueing by Default
If you have mailable classes that you want to always be queued, you may implement the ShouldQueue contract on the class. Now, even if you call the send method when mailing, the mailable will still be queued since it implements the contract:
use Illuminate\Contracts\Queue\ShouldQueue;
class OrderShipped extends Mailable implements ShouldQueue
{
// ...
}Queued Mailables and Database Transactions
When queued mailables are dispatched within database transactions, they may be processed by the queue before the database transaction has committed. When this happens, any updates you have made to models or database records during the database transaction may not yet be reflected in the database. In addition, any models or database records created within the transaction may not exist in the database. If your mailable depends on these models, unexpected errors can occur when the job that sends the queued mailable is processed.
If your queue connection's after_commit configuration option is set to false, you may still indicate that a particular queued mailable should be dispatched after all open database transactions have been committed by calling the afterCommit method when sending the mail message:
Mail::to($request->user())->send(
(new OrderShipped($order))->afterCommit()
);Alternatively, you may call the afterCommit method from your mailable's constructor:
<?php
namespace App\Mail;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
class OrderShipped extends Mailable implements ShouldQueue
{
use Queueable, SerializesModels;
/**
* Create a new message instance.
*/
public function __construct()
{
$this->afterCommit();
}
}[!NOTE]

Rendering Mailables
Sometimes you may wish to capture the HTML content of a mailable without sending it. To accomplish this, you may call the render method of the mailable. This method will return the evaluated HTML content of the mailable as a string:
use App\Mail\InvoicePaid;
use App\Models\Invoice;
$invoice = Invoice::find(1);
return (new InvoicePaid($invoice))->render();Previewing Mailables in the Browser
When designing a mailable's template, it is convenient to quickly preview the rendered mailable in your browser like a typical Blade template. For this reason, Laravel allows you to return any mailable directly from a route closure or controller. When a mailable is returned, it will be rendered and displayed in the browser, allowing you to quickly preview its design without needing to send it to an actual email address:
Route::get('/mailable', function () {
$invoice = App\Models\Invoice::find(1);
return new App\Mail\InvoicePaid($invoice);
});Localizing Mailables
Laravel allows you to send mailables in a locale other than the request's current locale, and will even remember this locale if the mail is queued.
To accomplish this, the Mail facade offers a locale method to set the desired language. The application will change into this locale when the mailable's template is being evaluated and then revert back to the previous locale when evaluation is complete:
Mail::to($request->user())->locale('es')->send(
new OrderShipped($order)
);User Preferred Locales
Sometimes, applications store each user's preferred locale. By implementing the HasLocalePreference contract on one or more of your models, you may instruct Laravel to use this stored locale when sending mail:
use Illuminate\Contracts\Translation\HasLocalePreference;
class User extends Model implements HasLocalePreference
{
/**
* Get the user's preferred locale.
*/
public function preferredLocale(): string
{
return $this->locale;
}
}Once you have implemented the interface, Laravel will automatically use the preferred locale when sending mailables and notifications to the model. Therefore, there is no need to call the locale method when using this interface:
Mail::to($request->user())->send(new OrderShipped($order));Testing
Testing Mailable Content
Laravel provides a variety of methods for inspecting your mailable's structure. In addition, Laravel provides several convenient methods for testing that your mailable contains the content that you expect. These methods are: assertSeeInHtml, assertDontSeeInHtml, assertSeeInOrderInHtml, assertSeeInText, assertDontSeeInText, assertSeeInOrderInText, assertHasAttachment, assertHasAttachedData, assertHasAttachmentFromStorage, and assertHasAttachmentFromStorageDisk.
As you might expect, the "HTML" assertions assert that the HTML version of your mailable contains a given string, while the "text" assertions assert that the plain-text version of your mailable contains a given string:
use App\Mail\InvoicePaid;
use App\Models\User;
test('mailable content', function () {
$user = User::factory()->create();
$mailable = new InvoicePaid($user);
$mailable->assertFrom('jeffrey@example.com');
$mailable->assertTo('taylor@example.com');
$mailable->assertHasCc('abigail@example.com');
$mailable->assertHasBcc('victoria@example.com');
$mailable->assertHasReplyTo('tyler@example.com');
$mailable->assertHasSubject('Invoice Paid');
$mailable->assertHasTag('example-tag');
$mailable->assertHasMetadata('key', 'value');
$mailable->assertSeeInHtml($user->email);
$mailable->assertSeeInHtml('Invoice Paid');
$mailable->assertSeeInOrderInHtml(['Invoice Paid', 'Thanks']);
$mailable->assertSeeInText($user->email);
$mailable->assertSeeInOrderInText(['Invoice Paid', 'Thanks']);
$mailable->assertHasAttachment('/path/to/file');
$mailable->assertHasAttachment(Attachment::fromPath('/path/to/file'));
$mailable->assertHasAttachedData($pdfData, 'name.pdf', ['mime' => 'application/pdf']);
$mailable->assertHasAttachmentFromStorage('/path/to/file', 'name.pdf', ['mime' => 'application/pdf']);
$mailable->assertHasAttachmentFromStorageDisk('s3', '/path/to/file', 'name.pdf', ['mime' => 'application/pdf']);
});use App\Mail\InvoicePaid;
use App\Models\User;
public function test_mailable_content(): void
{
$user = User::factory()->create();
$mailable = new InvoicePaid($user);
$mailable->assertFrom('jeffrey@example.com');
$mailable->assertTo('taylor@example.com');
$mailable->assertHasCc('abigail@example.com');
$mailable->assertHasBcc('victoria@example.com');
$mailable->assertHasReplyTo('tyler@example.com');
$mailable->assertHasSubject('Invoice Paid');
$mailable->assertHasTag('example-tag');
$mailable->assertHasMetadata('key', 'value');
$mailable->assertSeeInHtml($user->email);
$mailable->assertSeeInHtml('Invoice Paid');
$mailable->assertSeeInOrderInHtml(['Invoice Paid', 'Thanks']);
$mailable->assertSeeInText($user->email);
$mailable->assertSeeInOrderInText(['Invoice Paid', 'Thanks']);
$mailable->assertHasAttachment('/path/to/file');
$mailable->assertHasAttachment(Attachment::fromPath('/path/to/file'));
$mailable->assertHasAttachedData($pdfData, 'name.pdf', ['mime' => 'application/pdf']);
$mailable->assertHasAttachmentFromStorage('/path/to/file', 'name.pdf', ['mime' => 'application/pdf']);
$mailable->assertHasAttachmentFromStorageDisk('s3', '/path/to/file', 'name.pdf', ['mime' => 'application/pdf']);
}Testing Mailable Sending
We suggest testing the content of your mailables separately from your tests that assert that a given mailable was "sent" to a specific user. Typically, the content of mailables is not relevant to the code you are testing, and it is sufficient to simply assert that Laravel was instructed to send a given mailable.
You may use the Mail facade's fake method to prevent mail from being sent. After calling the Mail facade's fake method, you may then assert that mailables were instructed to be sent to users and even inspect the data the mailables received:
<?php
use App\Mail\OrderShipped;
use Illuminate\Support\Facades\Mail;
test('orders can be shipped', function () {
Mail::fake();
// Perform order shipping...
// Assert that no mailables were sent...
Mail::assertNothingSent();
// Assert that a mailable was sent...
Mail::assertSent(OrderShipped::class);
// Assert a mailable was sent twice...
Mail::assertSent(OrderShipped::class, 2);
// Assert a mailable was sent to an email address...
Mail::assertSent(OrderShipped::class, 'example@laravel.com');
// Assert a mailable was sent to multiple email addresses...
Mail::assertSent(OrderShipped::class, ['example@laravel.com', '...']);
// Assert a mailable was not sent...
Mail::assertNotSent(AnotherMailable::class);
// Assert 3 total mailables were sent...
Mail::assertSentCount(3);
});<?php
namespace Tests\Feature;
use App\Mail\OrderShipped;
use Illuminate\Support\Facades\Mail;
use Tests\TestCase;
class ExampleTest extends TestCase
{
public function test_orders_can_be_shipped(): void
{
Mail::fake();
// Perform order shipping...
// Assert that no mailables were sent...
Mail::assertNothingSent();
// Assert that a mailable was sent...
Mail::assertSent(OrderShipped::class);
// Assert a mailable was sent twice...
Mail::assertSent(OrderShipped::class, 2);
// Assert a mailable was sent to an email address...
Mail::assertSent(OrderShipped::class, 'example@laravel.com');
// Assert a mailable was sent to multiple email addresses...
Mail::assertSent(OrderShipped::class, ['example@laravel.com', '...']);
// Assert a mailable was not sent...
Mail::assertNotSent(AnotherMailable::class);
// Assert 3 total mailables were sent...
Mail::assertSentCount(3);
}
}If you are queueing mailables for delivery in the background, you should use the assertQueued method instead of assertSent:
Mail::assertQueued(OrderShipped::class);
Mail::assertNotQueued(OrderShipped::class);
Mail::assertNothingQueued();
Mail::assertQueuedCount(3);You may pass a closure to the assertSent, assertNotSent, assertQueued, or assertNotQueued methods in order to assert that a mailable was sent that passes a given "truth test". If at least one mailable was sent that passes the given truth test then the assertion will be successful:
Mail::assertSent(function (OrderShipped $mail) use ($order) {
return $mail->order->id === $order->id;
});When calling the Mail facade's assertion methods, the mailable instance accepted by the provided closure exposes helpful methods for examining the mailable:
Mail::assertSent(OrderShipped::class, function (OrderShipped $mail) use ($user) {
return $mail->hasTo($user->email) &&
$mail->hasCc('...') &&
$mail->hasBcc('...') &&
$mail->hasReplyTo('...') &&
$mail->hasFrom('...') &&
$mail->hasSubject('...');
});The mailable instance also includes several helpful methods for examining the attachments on a mailable:
use Illuminate\Mail\Mailables\Attachment;
Mail::assertSent(OrderShipped::class, function (OrderShipped $mail) {
return $mail->hasAttachment(
Attachment::fromPath('/path/to/file')
->as('name.pdf')
->withMime('application/pdf')
);
});
Mail::assertSent(OrderShipped::class, function (OrderShipped $mail) {
return $mail->hasAttachment(
Attachment::fromStorageDisk('s3', '/path/to/file')
);
});
Mail::assertSent(OrderShipped::class, function (OrderShipped $mail) use ($pdfData) {
return $mail->hasAttachment(
Attachment::fromData(fn () => $pdfData, 'name.pdf')
);
});You may have noticed that there are two methods for asserting that mail was not sent: assertNotSent and assertNotQueued. Sometimes you may wish to assert that no mail was sent or queued. To accomplish this, you may use the assertNothingOutgoing and assertNotOutgoing methods:
Mail::assertNothingOutgoing();
Mail::assertNotOutgoing(function (OrderShipped $mail) use ($order) {
return $mail->order->id === $order->id;
});Mail and Local Development
When developing an application that sends email, you probably don't want to actually send emails to live email addresses. Laravel provides several ways to "disable" the actual sending of emails during local development.
Log Driver
Instead of sending your emails, the log mail driver will write all email messages to your log files for inspection. Typically, this driver would only be used during local development. For more information on configuring your application per environment, check out the configuration documentation.
HELO / Mailtrap / Mailpit
Alternatively, you may use a service like HELO or Mailtrap and the smtp driver to send your email messages to a "dummy" mailbox where you may view them in a true email client. This approach has the benefit of allowing you to actually inspect the final emails in Mailtrap's message viewer.
If you are using Laravel Sail, you may preview your messages using Mailpit. When Sail is running, you may access the Mailpit interface at: http://localhost:8025.
Using a Global to Address
Finally, you may specify a global "to" address by invoking the alwaysTo method offered by the Mail facade. Typically, this method should be called from the boot method of one of your application's service providers:
use Illuminate\Support\Facades\Mail;
/**
* Bootstrap any application services.
*/
public function boot(): void
{
if ($this->app->environment('local')) {
Mail::alwaysTo('taylor@example.com');
}
}Events
Laravel dispatches two events while sending mail messages. The MessageSending event is dispatched prior to a message being sent, while the MessageSent event is dispatched after a message has been sent. Remember, these events are dispatched when the mail is being sent, not when it is queued. You may create event listeners for these events within your application:
use Illuminate\Mail\Events\MessageSending;
// use Illuminate\Mail\Events\MessageSent;
class LogMessage
{
/**
* Handle the event.
*/
public function handle(MessageSending $event): void
{
// ...
}
}Custom Transports
Laravel includes a variety of mail transports; however, you may wish to write your own transports to deliver email via other services that Laravel does not support out of the box. To get started, define a class that extends the Symfony\Component\Mailer\Transport\AbstractTransport class. Then, implement the doSend and __toString() methods on your transport:
use MailchimpTransactional\ApiClient;
use Symfony\Component\Mailer\SentMessage;
use Symfony\Component\Mailer\Transport\AbstractTransport;
use Symfony\Component\Mime\Address;
use Symfony\Component\Mime\MessageConverter;
class MailchimpTransport extends AbstractTransport
{
/**
* Create a new Mailchimp transport instance.
*/
public function __construct(
protected ApiClient $client,
) {
parent::__construct();
}
/**
* {@inheritDoc}
*/
protected function doSend(SentMessage $message): void
{
$email = MessageConverter::toEmail($message->getOriginalMessage());
$this->client->messages->send(['message' => [
'from_email' => $email->getFrom(),
'to' => collect($email->getTo())->map(function (Address $email) {
return ['email' => $email->getAddress(), 'type' => 'to'];
})->all(),
'subject' => $email->getSubject(),
'text' => $email->getTextBody(),
]]);
}
/**
* Get the string representation of the transport.
*/
public function __toString(): string
{
return 'mailchimp';
}
}Once you've defined your custom transport, you may register it via the extend method provided by the Mail facade. Typically, this should be done within the boot method of your application's AppServiceProvider service provider. A $config argument will be passed to the closure provided to the extend method. This argument will contain the configuration array defined for the mailer in the application's config/mail.php configuration file:
use App\Mail\MailchimpTransport;
use Illuminate\Support\Facades\Mail;
/**
* Bootstrap any application services.
*/
public function boot(): void
{
Mail::extend('mailchimp', function (array $config = []) {
return new MailchimpTransport(/* ... */);
});
}Once your custom transport has been defined and registered, you may create a mailer definition within your application's config/mail.php configuration file that utilizes the new transport:
'mailchimp' => [
'transport' => 'mailchimp',
// ...
],Additional Symfony Transports
Laravel includes support for some existing Symfony maintained mail transports like Mailgun and Postmark. However, you may wish to extend Laravel with support for additional Symfony maintained transports. You can do so by requiring the necessary Symfony mailer via Composer and registering the transport with Laravel. For example, you may install and register the "Brevo" (formerly "Sendinblue") Symfony mailer:
composer require symfony/brevo-mailer symfony/http-clientOnce the Brevo mailer package has been installed, you may add an entry for your Brevo API credentials to your application's services configuration file:
'brevo' => [
'key' => 'your-api-key',
],Next, you may use the Mail facade's extend method to register the transport with Laravel. Typically, this should be done within the boot method of a service provider:
use Illuminate\Support\Facades\Mail;
use Symfony\Component\Mailer\Bridge\Brevo\Transport\BrevoTransportFactory;
use Symfony\Component\Mailer\Transport\Dsn;
/**
* Bootstrap any application services.
*/
public function boot(): void
{
Mail::extend('brevo', function () {
return (new BrevoTransportFactory)->create(
new Dsn(
'brevo+api',
'default',
config('services.brevo.key')
)
);
});
}Once your transport has been registered, you may create a mailer definition within your application's config/mail.php configuration file that utilizes the new transport:
'brevo' => [
'transport' => 'brevo',
// ...
