The SailMail Association is a non-profit association of yacht owners that operates and maintains an email communications system for use by its members. SailMail email can be transferred via SailMail's own world-wide network of SSB-Pactor radio stations, or via satellite (Iridium, Inmarsat, Globalstar) or any other method of internet access (cellular networks, WiFi). The SailMail system implements an efficient email transfer protocol that is optimized for use over communications systems that have limited bandwidth and high latency. Satellite communications systems and SSB-Pactor terrestrial radio communications systems both have these characteristics. The SailMail email system's custom protocol substantially reduces the number of link-turn-arounds and implements compression, virus filtering, spam filtering, and attachment filtering. The combination of the protocol, compression, and filtering dramatically improves communications efficiency.
The SailMail Association also maintains its own world-wide network of SSB-Pactor private coast stations in the Maritime Mobile Radio Service. Email that is sent to a SailMail member's email address can be seamlessly retrieved via SSB radio, via satellite, or via any other access to the internet.
