Nextel Communications is launching NextMail, an application that merges instant walkie-talkie voice communication and e-mail, allowing customers to send voice messages as MP3 files embedded in e-mail messages on the press of a button.

NextMail features group e-mails and the recipient of a NextMail message can respond in text form.
Nextel subscribers can send NextMail messages from anywhere in Nextel’s U.S. network, or from Canada, Brazil, Argentina and Peru. Recipients of NextMail messages can be anywhere in the world and they do not need to be Nextel customers.
