Hi there,
I have a newsletter.
I send it to 5,000 people and I want to know who open the mail and who click on it.
So I undersatnd that it's not a problem to know who clicked but How can I know who open it.
I thought to put an img that is taken from my server and then when the user open the mail he "call" my server and take the pic.
But how can I know what is the specific ID that do that?
Or maybe u have another idea?
