Most of the time I can tell if a particular E-Mail is from an "Adult" site and I just mark as Adult and then delete. But once in a while I will open one by mistake and then I will close and delete.
Can such an E-Mail sender tell if I opened the e-mail and gather any info from me, such as addresses and the like? I am not talking about clicking on an enclosed link, just if I 'open' their stink'en e-mail
I know ones can send an e-mail that if I open will send a reply e-mail to let them know I did open it, but such does not seem to be happening here.
