Web site Sendible schedules sending messages to contacts in the future over email, text message, or social networks like Facebook and Myspace. Not only can you send messages to anyone on a schedule, but you can also update your status on sites like Facebook and Twitter on a schedule too.

The site also has special tools for setting up reminders for sending messages to yourself, options for recurring messages, and a great calendar tool that lists all your scheduled messages. Aside from message sending, Sendible features a robust contact management you’ll probably never use. Sendible is free to use but will cost you an email address to register.
Note: More than anything else, I love the SMS facility!! You can send Local/National/International SMS free of cost!! Plus, You can SCHEDULE the sms to be sent on a particular day at a particular time!!
