Introduction
Sending emails from a website is an essential feature for many applications, including contact forms, user notifications, and order confirmations. While PHP provides a basic mail() function, it is not always reliable or secure, especially in shared hosting environments.
PHPMailer is a powerful and widely used library that enables you to send emails using SMTP authentication, making the process more secure and dependable. If your website is hosted on Plesk, setting up PHPMailer is straightforward when you follow the correct steps.
In this article, we will walk you through the process of implementing PHPMailer on your Plesk-hosted domain so you can send emails efficiently and confidently.
What is PHPMailer?
PHPMailer is an open-source PHP library designed to simplify email sending from web applications. It provides an easy-to-use, object-oriented interface that is more flexible and reliable than PHP’s built-in mail() function.
It supports advanced features such as SMTP authentication, HTML emails, attachments, and secure email transmission, making it a preferred choice for developers.
Key Features of PHPMailer:
SMTP Support: Send emails using SMTP servers for improved reliability and control over delivery.
HTML Email Support: Create rich, styled email content with images, tables, and formatting.
Attachments: Easily attach files from the server or dynamically generated content.
Security (SSL/TLS): Supports secure connections to protect email data during transmission.
Error Handling: Provides detailed error messages to help troubleshoot issues quickly.
Steps to Implement PHPMailer in Plesk:

require DIR . '/src/Exception.php'; use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception; $mail = new PHPMailer(true); try {
$mail->isSMTP();
$mail->Host = 'Your-SMTP Server';
$mail->SMTPAuth = true;
$mail->Username = 'Sender email Address';
$mail->Password = 'Email account password';
$mail->SMTPSecure = 'ssl';
$mail->Port = 465; $mail->setFrom('Sender email Address', 'Your Name');
