Laravel 11 Jobs & Queues Explained with a Simple Email Example -

Introduction

Some tasks in a web application take time — sending emails, processing files, or calling external APIs.
If these tasks run during a request, your app becomes slow.

Laravel 11 solves this using Jobs & Queues, allowing tasks to run in the background.

In this post, you’ll learn:

What Laravel Jobs are
Why queues matter
A very small, real-world email queue example

This works perfectly in Laravel 11 and Laravel 12.

What Is a Job?

A Job is a class that represents a task you want to run later.

Examples:

Sending emails
Processing payments
Generating reports
Uploading files

Instead of running immediately, jobs are sent to a queue.

Use Case: Send Welcome Email in Background

We’ll build:

A Job
A Mail class
Dispatch the job from a controller

Step 1: Create the Job

php artisan make:job SendWelcomeEmail

app/Jobs/SendWelcomeEmail.php

<?php

namespace App\Jobs;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
use Illuminate\Support\Facades\Mail;

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

    protected string $email;

    public function __construct(string $email)
    {
        $this->email = $email;
    }

    public function handle(): void
    {
        Mail::raw('Welcome to our platform!', function ($message) {
            $message->to($this->email)
                    ->subject('Welcome Email');
        });
    }
}

Step 2: Dispatch Job from Controller

app/Http/Controllers/UserController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Jobs\SendWelcomeEmail;

class UserController extends Controller
{
    public function store(Request $request)
    {
        $request->validate([
            'email' => 'required|email'
        ]);

        SendWelcomeEmail::dispatch($request->email);

        return response()->json([
            'message' => 'User created. Email will be sent shortly.'
        ]);
    }
}

Step 3: Queue Configuration (Simple)

For beginners, use the database queue.

.env

QUEUE_CONNECTION=database

Run:

php artisan queue:table
php artisan migrate

Start the worker:

php artisan queue:work

Step 4: Define Route

routes/web.php

use App\Http\Controllers\UserController;

Route::post('/register', [UserController::class, 'store']);

Folder Structure

app/
 ├── Jobs/SendWelcomeEmail.php
 ├── Http/Controllers/UserController.php
routes/
 └── web.php

Why Queues Are Important

✔ Faster user response
✔ Heavy tasks run in background
✔ Better scalability
✔ Production-ready architecture

Common Beginner Mistakes

❌ Forgetting to run queue:work
❌ Running heavy logic inside controllers
❌ Not using queues for emails

Conclusion

Laravel Jobs & Queues are essential for building fast and scalable applications.
Even small projects benefit from background processing.

Once you understand this pattern, your Laravel apps instantly feel professional-grade.
