Requirements

Laravel 5, 6,7 or 8. Larave 9 and 10 are not supported.

Installation

Install the package into your Laraval application with composer:

composer require iwasherefirst2/laravel-multimail

Publish the config file:

php artisan vendor:publish --provider="IWasHereFirst2\LaravelMultiMail\MultiMailServiceProvider" --tag=config

Configure your email clients in config/multimail.php:

'emails'  => [
    '[email protected]' =>
        [
          'pass'     => env('first_mail_password'),
          'from_name'     => "Max Musterman",
        ],
    '[email protected]'  =>
        [
          'pass'     => env('second_mail_password')
        ],
],

Make sure to put your credentials in the .env file, so they don't get tracked in your repository.

For each mail you may specify multiple columns:

Usage

One may send a mail using \MultiMail instead of \Mail. The methods to, cc, bcc, locale are exactly the same as provided by the mail facade (note that locale is only available since Laravel 5.6).

The from method from MultiMail needs a string of an email provided in config/multimail.php. You can pass optionaly a second parameter as from name instetad of using the default falue given in the config. When using send or queue the mail will be send from the mail account specified in cofing/multimail.php.

Basic Examples

This example assumes that [email protected] and [email protected] have been specified in config/multimail.php.

// Send mail from [email protected]
\MultiMail::to($user)->from('[email protected]')->send(new \App\Mail\Invitation($user));

// Send from malaccount [email protected]
\MultiMail::to($user)->from('[email protected]')->locale('en')->send(new \App\Mail\Invitation($user));

Queued Mails

Queued mails work exactly the same as for the normal Mail facade, i.e. they are either send explicitly be the queue method or the mailable class implements the ShouldQueue contract.

// Queue Mail
\MultiMail::from('[email protected]')->queue(new \App\Mail\Invitation($user));

It is of course necessary to install a queue driver.

Specify in mailable

You may set to, cc, bcc, locale and from in your mailable class. In this case, you could reduce the basic example from above to:

// Send mail from [email protected]
\MultiMail::send(new \App\Mail\Invitation($user));

Mailable:

/**
 * Create a new message instance.
 *
 * @return void
 */
public function __construct($user)
{
  $this->to  = $user;
  $this->fromMailer = '[email protected]'
  $this->locale('en');
}

/**
 * Build the message.
 *
 * @return $this
 */
public function build()
{
    return $this->markdown('emails.invitation')
                ->subject('Invitation mail');
}

Bulk messages

For bulk messages, you may first require a mailer object. You can define a pause in seconds ($timeout) after a number of mails ($frequency) has been send.

$mailer = \MultiMail::getMailer('[email protected]' , $timeout, $frequency);

Then you can iterate through your list.

foreach($users as $user){
$mailer->send(new \App\Mail\Invitation($user));
};

Special Settings

Multiple Mail Providers

If you wish to send from mails with different provider, then you may create another provider in the provider array and reference it inside the emails array:

'emails'  => [
    '[email protected]' =>
        [
          'pass'     => env('first_mail_password'),
          'username' => env('first_mail_username'),
          'from_name'     => "Max Musterman",   
                                                    // <------ no provider given because 'default' provider is used
        ],
    'contact@other_domain.net'  =>
        [
          'pass'     => env('second_mail_password'),
          'username' => env('second_mail_username'),
          'from_name'     => "Alice Armania",
          'provider' => 'new_provider',            // <------ specify new provider here
        ],
],

'provider' => [
  'default' =>
    [
      'host'       => env('MAIL_HOST'),
      'port'       => env('MAIL_PORT'),
      'encryption' => env('MAIL_ENCRYPTION'),
      'driver'     => env('MAIL_DRIVER'),
    ],
  'new_provider' =>
    [
      'host'      => env('MAIL_HOST_PROVIDER_B'),
      'port'      => env('MAIL_PORT_PROVIDER_B'),
      'encryption' => env('MAIL_ENCRYPTION_PROVIDER_B'),
  'driver'     => env('MAIL_DRIVER_B'),
  // you may also add options like `stream`, `source_ip` and `local_domain`
    ]'
],

Default mailaccount

You may provide default credentials inside the email array from config/multimail.php:

'emails'  => [
    '[email protected]' =>
        [
          'pass'     => env('first_mail_password'),
          'username' => env('first_mail_username'),
          'from_name'     => "Max Musterman",
        ],
    '[email protected]'  =>
        [
          'pass'     => env('second_mail_password'),
          'username' => env('second_mail_username'),
          'from_name'     => "Alice Armania",
        ],
    'default' =>
      [
        'pass'            => env('MAIL_PASSWORD'),
        'username'        => env('MAIL_USERNAME'),
      ]
],

When first_mail_password and first_mail_username are empty, [email protected] will use credentials specified by default. This is useful for your local development, when you want to send all mails from one mailaccount while testing. This way you only need to specify MAIL_PASSWORD and MAIL_USERNAME locally.

Testing

Don't put credentials in local env

Do not specify any email accounts in your local .env. Otherwise you may risk to send testing mails to actual users.

Use one fake mail account or log

Use log driver or setup a fake mail SMTP account like mailtrap or similar services.

It is not needed to specify the same credentials for all your email accounts. Instead, simply provide a default mail account (see above Default mail account).

Use log mail driver on testing

To avoid latency, I recommend to always use the log mail driver when phpunit is running. You can set the mail driver in your phpunit.xml file like this: <env name="MAIL_DRIVER" value="log"/>.

Use Mocking

If you want to use the mocking feature Mail fake during your tests, enable use_default_mail_facade_in_tests in your config file config/multimail.php. Note that assertQueued will never be true, because queued mails are actually send through sent through a job.

Get Mail From Database

If you want to load your mail account configuration from database publish the package migrations:

php artisan vendor:publish --provider="IWasHereFirst2\LaravelMultiMail\MultiMailServiceProvider" --tag=migrations

In your migration folder are now two tabels, email_accounts and email_providers

Instead of adding emails to the config they should be added to the table email_accounts.

Make sure to update your config config/multimail.php:

<?php

return [

    'mail_settings_class' => \IWasHereFirst2\LaravelMultiMail\DatabaseConfigMailSettings::class,

    //...
];

The emails will now be read from the database instead from the configuration file. If no provider is provided in email_accounts (column provider is nullable), then the default profider from config/multimail.php will be considerd.

If you want to make customizations, copy the class \IWasHereFirst2\LaravelMultiMail\DatabaseConfigMailSettings somewhere in your application, adjust the namespace, and update the reference mail_settings_class in your config file.

Troubleshoot

Laravel 7 is not working

Please update to version 1.2.2 to support Laravel 7

For Package Developer

If you plan to contribute to this package, please make sure that the unit tests aswell as the integration tests all succeed. In order to test the integration tests please create a free mailtraip account, copy tests/.env.example to tests/.env and add your mailtrap API credentials in tests/.env. The integration tests will now send a test email to your mailtrap account and verify through the API if the mail was successfully send.

The package ships with a Dockerfile to make it easy to run the tests for you. Simply follow these steps:

docker-compose up --build 
docker-compose exec app bash 
composer install
./vendor/bin/phpunit
