LetterMeLater
Publisher's Description
From LetterMeLater:
LetterMeLater allows you to send emails to anyone you wish, with the ability to have them sent at any future date and time you choose. A feature missing from every email service is the ability to schedule when an email gets sent - you must click the "send" button at the exact moment of delivery. With LetterMeLater, you can write emails with your existing email address, and they will get sent at the exact date, or dates that you specify - down to the minute.
