Brevity enforced

Shortmail’s idea is that your daily messages should be snappy and to the point. Like a cross between Twitter and e-mail, Shortmail puts a 500-word character limit on all messages as gentle encouragement to get people to the point. Shortmail is integrated with Twitter, so anyone who has a micro-blogging account handle can grab a Shortmail account at <yourtwittername> Now, the company has released an app for the iPhone that lets you access your mini-messages from anywhere.

Designed like an instant-messaging app, the mobile app gives your mail the look and feel of text messages. The app is a good first effort from the service and makes it easy to send quick-fire messages from your mobile device. The layout focuses on showing you conversations, as opposed to individual messages, and the push notificationis a nice touch. Free, for iOS devices.
