Thread: Did They Read Your E-Mail? When?

You send out an important e-mail message reminding your coworker to bring copies of your PowerPoint presentation to the big meeting. You get there, and he doesn't have them. His excuse: He never got your e-mail. Possible, but questionable; anyway, you want to know for sure.

Send messages you want to monitor through DidTheyReadlt . The Web site embeds a tiny image in each e-mail it sends. When the e-mail is opened, the recipient's e-mail client, in many cases, will automatically send a request for the embedded image; when that request is made, DidTheyReadlt then knows that the e-mail was indeed opened, when it was opened, and for how long it was open.

If you really need to be sure that someone received a particular message, DidTheyReadlt works as advertised. The only catch: lE the recipient's e-mail client doesn't automatically download embedded images, DidTheyReadlt's tracking mechanism may not work.
