Received mail appears in cute little envelopes that users can interact with, while sending mail is just as simple. Zumbox offers a variety of tools to make sending mail of any format type (think HTML, Flash, Photoshop, Illustrator, QuarkXPress, CRM, and PostScript) to a variety of audiences a breeze. Plus, you can store contact information, transfer content and recipient lists via Zumbox’s secure FTP, and use the printer driver to send mail right from accounting software.

And don’t think that the electronic version of your mail that Zumbox sends is any less real than your regular mail. You can receive your bills, statements, special offices, personal mail, and interactive mail complete with audio and video.

Anyone with a US mailing address can send mail free of charge to specific addresses, mailing lists, and geographic regions, all the while saving the recipients’ time.

And yes, all of this is free, atleast for now.
