Is there a way to send an email and notification of when it was read. And if its possible to input the read receipt into mysql?
Right now I created a script that will generate a blank 1 pixel image and I have it in the email like <img src="mysite.com/image.php?id=xxxxx">
so the script will put in mysql the call for the image (when it was opened) and output a white pixel which isnt noticeable in the email. It's been working but I just wanted to have an alternative incase someone blocks images in emails like gmail does.
But is there an easier way to do this or is this really the only way?
