I'm looking to track the effectiveness of my html emails.... I dont want to include any scripts or anything that would get caught in the spam filters but i want to see how many people open my email. It's for an opt-in newsletter. Would this work: Insert an image into the html newsletter (a white 2X2px square or something) and put that into a secured folder on my server. The only use it would have is the email that I was sending so theoretically I could test how many people opened my email by how many times that image was downloaded right? 1 question though... if someone opened the email more than 1 time, would it count as 2 downloads or would it be okay because it's likely that the image was stored in their temp files? Ideally I would like to track WHO opens my emails, but i'm settling for this because i dont know of a way to do that other than requesting a read recipt, so if you have any ideas PLEASE tell me how to do it.
