How can i know if someone has opened an email?

I am working on an email system (PHP based) where hundreds of emails will be sent by the users and i want to track those emails so i will be able to know that email is opened or not ?

Can any one guide me how to do this ?

Thanks

  • The only way I know of - and it's not very reliable - is to send an HTML mail in which you include something like:

    PHP Code:

    <img src='http://www.domain.com/mailcheck.php?user=123'>

    image but in the process, you can track the GET user. You can also find a way to modifier the mail header so as to request a receipt - but I don't know how to do that - and it's also not reliable because of the voluntary nature of the request.
