I Want Sandy recently shut down (though rumor has it it’s coming back). If that means nothing to you, you’re probably not especially broken up about it. Sandy did have a number of incredibly useful features, many I will certainly miss.

Basically, Sandy was your personal assistant. You send her an email saying “remind me to pick up the kids tomorrow at 3 at soccer.” Then, tomorrow, you get an email with all the stuff you have to do that day, and later, a reminder to go get your *&^*( kids.

For people with Blackberries, email obsessions, or various other ailments requiring you to be constantly in front of your email, Sandy was a wonderful tool. With her gone, many people are looking for something to replace.

While HitMeLater doesn’t replace all of Sandy’s features, it can do one great thing: send you an email back, when you need to see it.

Using it is so easy, it’s the best reason to use it: just forward or send an email to __@hitmelater.com. The blanks can be “5minutes”, “24hours”, “6months”, “wednesday”, “december 9″, or your choice of a large number of timing options. Then, when your time has come, you get the email back. The email comes from HitMeLater, which is actually a good thing: you can filter out HitMeLater emails, knowing they’re the ones needing immediate attention.

Though there’s no support for exact times (which is a sizable oversight), you can get around it with a bit of cleverness. 27 hours is tomorrow at 4, and you can get to most times just from the number of hours away. As best I can tell, there’s no upward limit on the number of hours you can specify.

HitMeLater requires no signup, no registration, and nothing ever from you. There are, however, limitations. With the free account, you can only send 5 emails a day, and snooze them up to 24 hours. For me, that’s not a big deal. If it is, you can sign up for a Pro account for $12/year (NOT a lot), and get 1 month snoozes and unlimited emails. For $30/year, you get unlimited emails and a year of snoozes.

The service is basic, the features are few, but HitMeLater does exactly what it’s supposed to: Snooze your email, and put it back in front of your eyes when you need it to.

So, fire off that “pick up the kids at soccer” to tuesday@hitmelater.com, and stay out of the trouble Sandy once helped you avoid.
