How to track email statistics?

Question

Email

How to track who opened the letter from the email list?

Answer 1

Expanding on @only-victor's answer

<?php
$src = './myimage.png'; //путь к реальной картинке
$image = imagecreatefrompng($src); //грузим её с помощью GD
header("Content-type: image/png"); //говорим браузеру что будем отдавать PNG
imagepng($image); отдаём картинку

//тут ваш код

accordingly, you can insert it into the letter
and it will be loaded from your server and execute the code, but for the same gmail, if I'm not mistaken, pictures are disabled by default

Answer 2

Look at the RFC, there is a parameter responsible for the "With confirmation" feature. But it only includes in the letter the possibility that the recipient must approve the sending of such confirmation. This is usually done only in the case of expected emails. For some reason it seems to me that you are going to send spam and it will not work for you ....

Answer 3

Usually they embed an iframe or img with a link to a script that calculates statistics. When the email is opened, the iframe or img makes a request to your script.
