Laravel – Test email using tinker

Once you run following command, it will send email to [email protected]. First parameter is a view. In this example, I have used welcome.blade.html view as this is just for a test purchase.

Note, if your provide another name as a first parameter, the mail won’t be sent. First parameter is a view. So, it should be a view available in your laravel project.

// 1
php artisan tinker

// 2
Mail::send('welcome', [], function($message) { $message->to('[email protected]')->subject('Testing mails '); });
