Possible Duplicate:Manage un-replied GMail conversations Is there a way to get a notice if I send an email to someone expecting a reply, but after a few days they haven't replied to it?Either something already in gmail, or  an extension would also work.For example if I send a friend a message like hey I'm coming to New York next weekend, where should we meet I would like to be notified if they didn't reply to it so I can remember to try to reach them through other means.
