Letterpop is an amazing AJAX/Web 2.0 online newsletter creator. You can choose from a number of templates and upload your own images and photos. One of the nicer features is that you do not need to create an account to create a basic newsletter, so it’s really easy to give this app a no strings attached test drive. More and more people are starting to use newsletters as a more direct way of reaching their audience, especially if their blog or website is part of a larger business model.
Newsletters that  feature high-quality content do tend to get sent to the receiver’s inbox and in turn opened a very high percentage of the time, and whatever your motive for creating them is you need a good tool. If you’ve been thinking about it take a look at Letterpop.
