I do not know that its spam right away, but I am getting info that people that send me an email can get a read receipt from my account once I read their email. How can you remove this feature and terminate anyone from receiveing an email alert as to when someone read their email.
If I'm reading you right, you're saying that when a certain party sends you an email, they can get some kind of notice that you opened it? Is that right? If so, they are using some kind of third-party commercial email system that has that feature in it. Normally, read receipts are strictly voluntary on the part of the recipient. So if you are not getting the read receipt request and answering it, there is nothing you could control that would stop them getting their notice.
