TwitterMail allows you to send posts via email to Twitter.com and notifies you via email if there are personal replies.

Why is this so spectacular? Because it changes Twitter from a 'pull' platform into a 'push' platform. No more reloading and browsing back looking for replies. You simply check your email and see if there were any reactions. Then you can reply via email or browse to Twitter.com to continue the conversation.

And there are a lot more features:

- Post to Twitter -
Send an e-mail to your secret TwitterMail address. The body of the message will be published in your Twitter Profile. For a normal message, you should always leave the subject-line empty.

- Get new replies in your mailbox -
If a friend send you a post on twitter (by using @yourusername) we will send it to your emailaddress. You can enable/disable this in your settings.

- Get the Timeline -
Send a message with 'Friends' as the subject and you will recieve one message with the last 20 posts from all of your friends.

- Send a book -
At Twitter.com you only have 140 characters to tell your story. But if you use TwitterMail we will keep the full message here and post the first 140 characters to Twitter with a 'Read More' link at the end.

- Future Tweets -
Schedule your posts: Add a time to your subject-line when you want you post to be published. Example: "21:00" will publish your post at 21:00 (9 PM) GMT+1. Make your friends believe you are Twittering day and night.
