php-mailer is a simple PHP API that accepts POST requests with name and email, allowing you to send emails from a hosting service like World4You. This is perfect for use with a static frontend, such as a contact form built with React.
To install php-mailer, simply clone this repository und upload mailer.php to your server. Adapt accepted fields, sender email and message to your liking.
Once it's uploaded, make a POST request to {yourURL}/mailer.php. Adapt your .htaccess if you want to remove the file extension.
