Download the PHP package spatie/laravel-mail-preview without Composer

A mail driver to quickly preview mail

This package can display a small overlay whenever a mail is sent. The overlay contains a link to the mail that was just sent.

This can be handy when testing out emails in a local environment.

Installation

You can install the package via composer:

Configuring the mail transport

This package contains a mail transport called preview. We recommend to only use this transport in non-production environments. To use the preview transport, change the mailers.smtp.transport to preview in your config/mail.php file:

Registering the preview middleware route

The package can display a link to sent mails whenever they are sent. To use this feature, you must add the Spatie\MailPreview\Http\Middleware\AddMailPreviewOverlayToResponse middleware to the web middleware group in your kernel.

You must also add the mailPreview to your routes file. Typically, the routes file will be located at routes/web.php.

This will register a route to display sent mails at /spatie-mail-preview. To customize the URL, pass the URL you want to the macro.

Publishing the config file

Optionally, you can publish the config file with:

This is the content of the config file that will be published at config/mail-preview.php:

Publishing the views

Optionally, you can publish the views that render the preview overlay and the mail itself.

You can modify the views that will be published at resources/views/vendor/mail-preview to your liking.

Usage

Everytime an email is sent, an .html and .eml file will be saved in the directory specified in the storage_path of the mail-preview config file. The name includes the first recipient and the subject:

You can open the .html file in a web browser. The .eml file in your default email client to have a realistic look of the final output.

Preview in a web browser

When you open the .html file in a web browser you'll be able to see how your email will look.

At the beginning of the generated file you'll find an HTML comment with all the message info:

Events

Whenever a mail is stored on disk, the Spatie\MailPreview\Events\MailStoredEvent will be fired. It has three public properties:

• message: an instance of Swift_Mime_SimpleMessage
• pathToHtmlVersion: the path to the html version of the sent mail
• pathToEmlVersion: the path to the email version of the sent mail

Making assertions against sent mails

Currently, using Laravel's Mail::fake you cannot make any assertions against the content of a mail, as the using the fake will not render the mail.

The SentMails facade provided this package does allow you to make asserts against the content.

This allows you to make assertions on the content of a mail, without having the mailable in scope.

Let's explain other available assertions method using this mailable as example.

In your code you can send that mailable with:

In your tests you can assert that the mail was sent using the assertSent function. You should pass a callable to assertSent which will get an instance of SentMail to it. Each sent mail will be passed to the callable. If the callable returns true the assertions passes.

You can use as many assertion methods on the SentMail as you like.

The Spatie\MailPreview\Facades\SentMails has the following assertions methods:

• assertCount(int $expectedCount): assert how many mails were sent
• assertLastContains(string $expectedSubstring): assert that the body of the last sent mail contains a given substring
• assertSent($findMailCallable, int $expectedCount = 1): explained above
• assertTimesSent(int $expectedCount, Closure $findMail)
• assertNotSent(Closure $findMail)

Additionally, the Spatie\MailPreview\Facades\SentMails has these methods:

• all: returns an array of sent mails. Each item will be an instance of sentMail
• count(): returns the amount of mails sent
• last: returns an instance of SentMail for the last sent mail. If no mail was sent null will be returned.
• lastContains: returns true if the body of the last sent mail contains the given substring
• timesSent($findMailCallable): returns the amount of mails the were sent and that passed the given callable

The sentMail class provides these assertions:

• assertSubjectContains($expectedSubstring)
• assertFrom($expectedAddress)
• assertTo$expectedAddress)
• assertCc($expectedAddress)
• assertBcc($expectedAddress)
• assertContains($substring): will pass if the body of the mail contains the substring

Additionally, sentMail contains these methods:

• subject(): return the body of a mail
• to(): returns all to recipients as an array
• cc(): returns all cc recipients as an array
• bcc(): returns all bcc recipients as an array
• body(): returns the body of a mail
• subjectContains): returns a boolean
• hasFrom($expectedAddress): return a boolean
• hasTo($expectedAddress): return a boolean
• hasCc($expectedAddress): return a boolean
• hasBcc($expectedAddress): return a boolean
