Question

I have a simple mail sending application which runs in python using Django. After sending an email is there a way to see if the recipient has opened it or is it still un-opened?
if so how can i do it?

Answer 1

The two ways to check that I know of are return receipts and checking to see if an image has been loaded. Neither is very reliable. I think the image one is the more reliable of the two, though.

You could take a pluggable app for confirming a link is being clicked, but instead of putting the link in the email, put an image in the email. This would require changing the confirm_email view to output an image (maybe an empty one).

The above library is for confirming passwords but it ought to work for checking that emails are being read, too.
