Easy Writer is a free iPhone application that enhances the email experience from the device. Users can write a new message in the Mail after which the application can be opened in the landscape mode. For better readability, users can even zoom in to the text. When a user is done writing the message, he/she just have to press the Send to Mail button at the upper right corner of the application. Until these features are added to the Mail by Apple, this application is a good alternative.
