I've recently started using a service called Hit Me Later. The site bills itself as a "snooze button for your e-mail." I signed up for the Pro package for $12 per year, which limits me to delaying e-mail to a maximum of up to one month. It's cheap, and money well spent. Hit Me Later enables me to carefully tailor exactly... Oh, what the hell: It helps me procrastinate. I can forward e-mails any number of hours, days or weeks -- or to be sent back on a specific day -- all by which e-mail address I use. For example, if I forward e-mail to email@example.com, I get it in three hours. If I send to firstname.lastname@example.org, I get it in three days (not 3D). Nice!
The reason I need Hit Me Later is that Gmail itself offers no way to schedule e-mails. It's a simple enough feature, and massively useful. With the ability to schedule e-mails, you could:
* Send someone a request, then forward your own request to yourself a week later to make sure that person did what you asked.
* Schedule Twitter posts via e-mail
* Forward e-mails to the future if you're too busy at present
* Send people driving directions so they get them just before actually driving
The list goes on and on. The ability to schedule e-mails is a basic feature that would be easy for Google to implement. How about it, Google?
