Despite the fact that we now live in a world where communication is very much digital and paper trails are rapidly diminishing, there are still instances where physical mail is necessary and there are many who may even prefer the personal touch of a good old fashioned letter or postcard. MailWriter brings the convenience of online, digital functionality to the process of sending letters. It's a cloud mailing service that allows users to create and send letters, postcards or complete mailings directly from whatever device they're working from. The MailWriter API makes this functionality available to be integrated into other websites and applications as well.
