Enfour today introduces POSTpone! 1.0 for iOS, their app that allows the user to compose an email or SMS and then set a reminder to send at a specified date or time. The app lets you compose messages when the inspiration strikes you and not have worry about disturbing the receiver at odd hours or even long before the time is right. With POSTpone!, messages arrive when and only when they should. It lets users review messages one last time before sending, and automates tedious recurring messages.
