1. Setting Up Laravel Mail Dependencies

To begin, ensure that you have the necessary dependencies installed for Laravel’s mailing functionality. Laravel relies on the SwiftMailer library, which provides a simple API for sending emails. You can include the required dependencies by using Composer, Laravel’s package manager.

2. Configuring Email Settings

Next, configure the email settings in the .env file located in the root directory of your Laravel project. These settings are essential for Laravel to connect with your email service provider. For instance, if you are using Gmail, the configuration might look like this

MAIL_MAILER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=your-email@gmail.com
MAIL_PASSWORD=your-email-password
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS=your-email@gmail.com
MAIL_FROM_NAME="${APP_NAME}"

Ensure that you adjust the settings based on the requirements of your chosen email service provider.

3. Creating a Mailable Class

In Laravel, Mailable classes provide a convenient way to generate email templates. To create a new Mailable class, use the following command

php artisan make:mail WelcomeEmail

Executing this command generates a new WelcomeEmail class within the app/Mail directory of your Laravel project.

4. Customizing the Mailable Class

Open the generated WelcomeEmail class and customize it according to your needs. You can define the email’s subject, recipient, and any additional data to pass to the email template. Here’s an example

<?php

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;

class WelcomeEmail extends Mailable
{
    use Queueable, SerializesModels;

    public function build()
    {
        return $this->view('emails.welcome');
    }
}

5. Creating an Email Template

Create an email template file within the resources/views/emails directory. For instance, you can create a welcome.blade.php file and customize the HTML content of the email.

6. Sending Transactional Emails

To send transactional emails, use the Mail facade provided by Laravel. In your application code, call the send method with the WelcomeEmail Mailable class. Here’s an example

use App\Mail\WelcomeEmail;
use Illuminate\Support\Facades\Mail;

// Inside your controller or wherever you want to send the email
public function sendWelcomeEmail()
{
    $user = User::find(1); // Fetch the user you want to send the email to

    Mail::to($user->email)->send(new WelcomeEmail());
}

Ensure that you update the User::find(1) part with the appropriate logic to retrieve the user you intend to send the email to.

7. Advanced Email Features

Laravel’s email system offers additional features that you can explore based on your requirements. Some examples include adding attachments to emails, embedding inline images, and sending emails asynchronously using queues.

Conclusion

Sending transactional emails using PHP and Laravel is a breeze with Laravel’s built-in Mail class and configuration options. By following the steps outlined in this guide, you can ensure efficient and reliable delivery of important information to your users. Take advantage of Laravel’s email features to enhance your application’s communication capabilities and provide a seamless user experience.

Remember to always test your email functionality thoroughly and consider implementing email logging to monitor the email delivery process effectively. Happy coding and happy emailing!
