In the old days, when you had a Word document that you wanted to send in the mail, you had to print it out, walk to a post office, buy stamps, envelopes, and more. That was incredibly cumbersome, and requires you to own a printer, have paper, etc. Today, with Mailform, you can post your letters via USPS First Class Mail or USPS Certified Mail, with Mailform, right from Microsoft Word.
