How to queue Laravel 5.7 "email verification" email sending

Yes! It's possible. And to do that you will have to rewrite the sendEmailVerificationNotification in your App\User. This method is provided by the Illuminate\Auth\MustVerfiyEmail trait. The method sendEmailVerificationNotification notifies the created user by sending an Email as defined in the Illuminate\Auth\Notifications\VerifyEmail Notification class.

// This is the code defined in the sendEmailVerificationNotification
public function sendEmailVerificationNotification()
{
    $this->notify(new Notifications\VerifyEmail);
}

You can change this method to not notify directly the user. You will have to define a Job which you will dispath in the sendEmailVerificationNotification method instead of notifying the created user.

In the Job class you will create a handle method where you can send the email to the user, but you must provide the $user to the Job which can be performed by passing it as a parameter to the dispatch method like this:

public function sendEmailVerificationNotification()
{
    VerifyEmail::dispatch($this);
}

$this represents the created user and the App\Jobs\VerififyEmail job (which you will create) will receive all the parameters passed to the dispatch in its __construct

The code of the VerifyEmail will look like this:

namespace App\Jobs;

use App\User;
use Illuminate\Bus\Queueable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Auth\Notifications\VerifyEmail;

class VerifyEmail implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    protected $user;

    public function __construct(User $user)
    {
        $this->user = $user;
    }

    public function handle()
    {
        // Here the email verification will be sent to the user
        $this->user->notify(new VerifyEmail);
    }
}

My solution is for if you gonna register a user manually in the controller. Laravel already created the Registered event and its listener SendEmailVerificationNotification.

-first configure queue in application in .env file update QUEUE_CONNECTION=database. for more queue documentation read https://laravel.com/docs/6.x/queues

• publish queue table by php artisan queue:table

• php artisan migrate

• php artisan make:job EmailVerificationJob

• in EmailVerificationJob.php add public variable

  public $user;

• in EmailVerificationJob.php constructor

  public function __construct(User $user) { $this->user = $user; }

• in EmailVerificationJob.php handle function write event(new Registered($this->user)).

• in your controller if user created successfully add this code for job to work.

  EmailVerificationJob::dispatch($user) ->delay(now()->addSeconds(5)); here job delay for 5 seconds.

• at the end you must start queue worker php artisan queue:work --tries=3 . here tries means how many times queue should try the job.

Update#1

this solution I used in Laravel 8.

first create SendEmailVerificationNotification notification class

php artisan make:notification SendEmailVerificationNotification

app/Notifications/SendEmailVerificationNotification.php file content will be this one. here we are going to extend Laravel default SendEmailVerificationNotification class and implement should queue

<?php

namespace App\Notifications;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
use Illuminate\Notifications\Notification;

class SendEmailVerificationNotification extends \Illuminate\Auth\Listeners\SendEmailVerificationNotification implements ShouldQueue
{
    use Queueable;
}

the last step is editing EventServiceProvider class $listen array. Comment out default notification of Registered event and add custom notification which we have created.

use App\Notifications\SendEmailVerificationNotification as QueuedSendEmailVerificationNotification;
use Illuminate\Auth\Events\Registered;
//use Illuminate\Auth\Listeners\SendEmailVerificationNotification;

protected $listen = [
        Registered::class => [
//            SendEmailVerificationNotification::class,
            QueuedSendEmailVerificationNotification::class
        ],

];
