This package introduces a new preview mail driver for Laravel that when selected will render the content of the sent email and save it as both .html and .eml files.


Begin by installing the package through Composer. Run the following command in your terminal:

composer require themsaid/laravel-mail-preview

Then publish the config file:

php artisan vendor:publish --provider="Themsaid\MailPreview\MailPreviewServiceProvider"

Finally, change the mailers.smtp.transport to preview in your config/mail.php file:

'mailers' => [
    'smtp' => [
        'transport' => 'preview',
        // ...
    // ...

How it works

Everytime an email is sent, an .html and .eml file will be generated in storage/email-previews with a name that includes the first recipient and the subject:


You can open the .html file in a web browser, or open the .eml file in your default email client to have a realistic look at 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, however there might be some differences that varies from one email client to another.

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

From:{"":"Acme HQ"},
to:{"":"Jack Black"},
cc:[{"":"Acme Finance"}, {"":"Acme Management"}],
subject:Invoice #000234

Package Configurations

From the config/mailpreview.php file you'll be able to change the output location of the preview files as well as the maximum lifetime for keeping previews, after this time old previews will get removed.

Logged out after clicked on the preview link

You will always lose your current session if you click on the generated notification link. This is because Laravel stores the session in an encrypted cookie. To change this behavior, you have to adjust the middleware property in the config/mailpreview.php file to match the following snippet:

    'middleware' => [
