How to run an event or function when a user verifies their account by using a Laravel listener.

Start by creating a listener in Artisan

php artisan make:listener SendVerifiedWelcomeMail

You can find this file in app/Listeners.

Inside SendVerifiedWelcomeMail.php you will find a function called handle() this function will be run when a user verifies their account.

public function handle(Verified $event)
{
    Mail::to($event->user->email)->send(new Welcome());
}

Above is a sample send mail call.

Finally, the most important part is to register this listener in the app/Providers/EventServiceProvider.php file in the $listen array:

Verified::class => [
   SendVerifiedWelcomeMail::class
],

Now when Verified gets broadcast (automatically) SendVerifiedWelcomeMail will be called upon.
