Sailmail
SailMail is radio based e-mail system designed for boat owners operating beyond line-of-sight radio links to the internet. Much of its underlying technology is built upon the Winlink software originally developed by amateur radio enthusiasts.
Operation on SailMail network frequencies requires a PACTOR modem and an SSB radio. Sailmail operators do not need to hold an amateur radio license, as is the case for the similar Airmail product.
