PHP Email Tracker: Track the sending and receiving status of emails

With the widespread application of email in daily work and life, sometimes we hope to know that we The sending and receiving status of sent emails. This is why it is important to develop a PHP email tracker. With PHP Email Tracker, we can easily track the status of emails, including sent, received, opened and clicked.

Below I will introduce you to the implementation of a simple PHP email tracker and provide specific code examples.

First, we need to use PHP’s built-in functions to send emails. In PHP, we can use the mail function to send emails. Here is a simple example:

$to = "recipient@example.com";
$subject = "Hello";
$message = "This is a test email.";

// 添加自定义邮件头
$headers = "From: sender@example.com
";
$headers .= "Reply-To: sender@example.com
";
$headers .= "X-Mailer: PHP/" . phpversion();

// 发送邮件
mail($to, $subject, $message, $headers);

In the above code, we specify the recipient's email address, the subject and content of the email, and then use the mail function to send the email. Please make sure the PHP server is configured correctly to send emails.

To implement the email tracking function, we need to add a tracking pixel (tracking pixel) or tracking link (tracking link) to the email. When the recipient opens the email, the tracking pixel or link will load, notifying us that the email has been opened.

The following is an example of using a tracking pixel:

$to = "recipient@example.com";
$subject = "Hello";
$message = "This is a test email.";

// 生成追踪像素的HTML代码
$trackingPixel = "<img  src="http://your-website.com/track.php?email=" . urlencode($to) . ""    style="max-width:90%"  style="max-width:90%" alt="PHP Email Tracker: Track the sending and receiving status of emails." >";

// 添加自定义邮件头
$headers = "From: sender@example.com
";
$headers .= "Reply-To: sender@example.com
";
$headers .= "X-Mailer: PHP/" . phpversion();

// 将追踪像素插入邮件内容
$message .= "

" . $trackingPixel;

// 发送邮件
mail($to, $subject, $message, $headers);

In the above code, we generated the HTML code for a tracking pixel and inserted it at the end of the email content. Please replace http://your-website.com/track.php with the URL of your own tracking pixel handler.

Next, we need to create a PHP file track.php that handles the tracking pixel. The file will be loaded as an image, so we need to output a 1x1 pixel image in the code. The following is a simple example:

<?php
// 获取传递的参数
$email = $_GET['email'];

// 在此处执行你的追踪逻辑，例如记录邮件已被打开的状态到数据库

// 输出1x1像素的图像
header("Content-Type: image/gif");
echo base64_decode("R0lGODlhAQABAIAAAP///wAAACwAAAAAAQABAAACAkQBADs=");
?>

In the above code, we obtain the passed email parameters and perform tracking operations in the processing logic. Here you can log tracking status to a database or other storage device.

Finally, when someone opens the email and loads the tracking pixel, we can determine the read status of the email based on a record in the database.

It should be noted that due to security and privacy issues, we are required to include an unsubscribe option in every email and to comply with relevant legal and compliance regulations. Ensure that when developing and using email trackers, you respect users' privacy rights and use appropriate practices.

In summary, by using PHP email tracker, we can easily track the status of emails, including sent, received, opened and clicked. This article provides a simple implementation and specific code examples. It only gives a basic principle that can be expanded and optimized according to specific needs. I hope this article will be helpful for everyone to understand and implement PHP email tracker.
