Learn how to send personalized bulk emails through PHP and PHPMAILER

In modern society, email has become one of the important ways for people to communicate and communicate. For enterprises, email sending is also one of the common marketing and promotion methods. When we need to send emails to a large number of users, how to implement personalized batch email sending is a problem that needs to be solved.

PHP is a commonly used server-side scripting language that can run on a web server. PHPMAILER is an excellent email sending library that can easily send emails through PHP. Combining PHP and PHPMAILER, we can implement batch email sending of customized content.

First, we need to download and introduce the PHPMAILER class library. The latest version of PHPMAILER can be downloaded from the official website (https://github.com/PHPMailer/PHPMailer). After unzipping the file, copy the PHPMailer-master folder to our project directory and introduce PHPMAILER at the beginning of the PHP file.

require 'PHPMailer-master/src/PHPMailer.php';
require 'PHPMailer-master/src/SMTP.php';
require 'PHPMailer-master/src/Exception.php';

Next, we need to create a function for sending emails. It can be named sendEmail. The function accepts two parameters, namely the recipient's email address and the content of the sent email.

function sendEmail($to, $content) {
    $mail = new PHPMailerPHPMailerPHPMailer();
    $mail->CharSet = 'UTF-8';
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com'; // 邮箱服务器地址
    $mail->SMTPAuth = true;
    $mail->Username = 'your_email@example.com'; // 发送邮件的邮箱地址
    $mail->Password = 'your_password'; // 发送邮件的邮箱密码
    $mail->SMTPSecure = 'ssl';
    $mail->Port = 465;

    $mail->setFrom('your_email@example.com', 'Your Name'); // 发送者的邮箱地址和名称
    $mail->addAddress($to); // 接收者的邮箱地址

    $mail->isHTML(true);
    $mail->Subject = 'Subject of the Email';
    $mail->Body = $content;
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients.';
    
    if (!$mail->send()) {
        echo 'Mailer Error: ' . $mail->ErrorInfo;
    } else {
        echo 'Message sent!';
    }
}

In the above code, we first created a PHPMAILER instance and set the relevant configuration of the email, such as server address, authentication information, sender information, etc. Next, we set the sender's email address and name through the setFrom function, and set the recipient's email address through the addAddress function. Set the email content to HTML format through the isHTML function, and set the subject and content of the email through Subject, Body and AltBody respectively. Finally, send the email through the send function and perform corresponding processing based on the sending result.

In actual use, we can expand according to needs, such as supporting multiple recipients, sending attachments, adding email header information, etc.

Next, let’s take a look at how to implement personalized email content. We can dynamically generate email content based on user information to achieve personalized email delivery.

$users = [
    ['email' => 'user1@example.com', 'name' => 'User1', 'content' => 'Hello User1!'],
    ['email' => 'user2@example.com', 'name' => 'User2', 'content' => 'Hello User2!'],
    // 添加更多用户信息
];

foreach ($users as $user) {
    $content = 'Dear ' . $user['name'] . ',<br><br>' . $user['content'] . '<br><br>Best regards,<br>Your Name';
    sendEmail($user['email'], $content);
}

In the above code, we create an array containing user information. By traversing the array, we can dynamically generate email content and call the sendEmail function to send the email. In this way, we can achieve personalized bulk mailing.

Through PHP and PHPMAILER, we can easily implement personalized batch email sending. We can easily complete various email sending tasks by combining the functions and syntax of PHPMAILER and flexibly using PHP's programming capabilities. Whether it is promotional emails, notification emails, or other types of emails, they can be flexibly customized through this method. I hope this article can be helpful to everyone’s study and practice!
