NudgeMail provides one feature: it turns any e-mail client into a reminder system. So say you receive a message that necessitates a reply, but not until Friday. Simply forward the e-mail to "email@example.com" and, on Friday, the message will be sent back to you for response. You can also schedule items for particular dates; for example, for the 22nd of November, you would forward the message to "firstname.lastname@example.org." It's really as simple as that. There are no registrations, no users, no widgets to toy with--just e-mail. And as many of us know, forwarding an e-mail is about the quickest and easiest process there is. Better yet, NudgeMail works from pretty much any platform--Android, BlackBerry, iPhone, Yahoo, Outlook, Gmail...the list goes on and on. And it's completely free, at least for now.
