Subscribe system in PHP and AJAX | Source Code

The subscribe system is known as the newsletter system. The subscription system is used to receive user emails, and send post notifications via email. You can create a subscribe system in PHP, and AJAX with the MYSQL database. The newsletter features can be created in PHP programming with AJAX, jQuery, Bootstrap, and MYSQL database. Using this system, the user can become a subscriber of your website. First of all, the user enters the email in subscribe form text box and clicks on subscribe button. After that AJAX responds and executes the PHP file. First of all, we check whether an email already exists or not.

If the email does not exist then insert the email in the MYSQL database table and send a confirmation email to the subscriber with a verification link and unsubscribe link. 
A user can verify email. We always send emails to all verified emails. In this system, we created an email-sending form from where the admin can send emails to all confirmed subscribers. 
This is the process of the newsletter. You can create subscribe and unsubscribe features with this source code. You will get the complete newsletter source code here in a zip file.
