How can I check to see whether someone read the email I sent them yet?

I just sent an email (using Yahoo) to someone and I want to know how I can tell if that person read it yet?

It doesn't work with Yahoo Mail Classic or New Yahoo Mail. Mail plus has the read receipt option, but it is not a free service.





Note: even when using mail plus or any of the other mail progs, you do not have the guaranty that you get a read receipt because a recipient can opt out of sending such notices. Reason behind this: by denying a read receipt, you make sure that spammers don't know whether they hit a real mail address.





There is a program called "SpyPig" which could help you get read receipts. But it only works if both sender and receiver allow html-mail. Because in html-mail you can include tracking cookies which notify you when an e-mail is opened. It's exactly the kind of program SPAMMERS use, and therefore you should never allow html-mail...
Reply:aol customers know when a person has read emails they sent. Yahoo should do the same! Report Abuse

Reply:The only way you can tell is when you get a response back. It completely sucks. I think Yahoo should develop the program to include a way to tell if the messages have been read.
