Honestly said it doesn’t get any easier than this when it comes to e-mail reminders. A site called HitMeLater recently launched by this guy is one of those things where you wonder why someone didn’t think of this before.
How it works (according to the site itself):
Just forward any email to email@example.com and we’ll resend it to you 24 hours later. You can replace "24" with any number or day. For example, forward it to firstname.lastname@example.org and you’ll get it back four hours later. Send it to email@example.com and we’ll send it back to you the first Wednesday morning after today.
Having "re-forwarded" mail like done via the address itself takes a whole lot of b.s. out of the process of setting a reminder. This is stupidly easy and that’s just plain awesome.
As a side note, I also credit Phil with the best song in the world (yes I was the guy who said that even though I can’t link it for obvious reasons) and the best cover song in the world (that one I can link).
