A simple, cost effective email solution for small vessels


Using our 20+ years of experience providing an email service to large commercial merchant fleets, GTMaritime has developed a robust, simple and cost effective email solution specifically optimised for smaller vessels such as barges, fishing vessels, inland cruisers and leisure craft.


In having a single email address for each vessel SeaMail provides a simple, cost effective, communication solution for smaller vessels.

SeaMail has been developed to ensure that the system is simple to use, allowing you to easily read, forward and reply to emails as well as manage attachments and filing ensuring that valuable time is not taken up with email management.

The shoreside dashboard allows you to set up rules and manage emails to help control costs and restrict unnecessary emails from getting through.

In being specifically designed for use over satellite, SeaMail deals with high latency circuits and multiple connection management, making communications efficient and cost effective.

When the connection is lost mid transmission, SeaMail will start again from where it left off rather than going back to the beginning, saving you airtime costs, particularly in heavy weather or high latitudes.

In offering a simple installation solution SeaMail does not require a lengthy and complicated set up process. This allows you to begin accessing your emails straight away saving you time and  resource.

Our systems have multiple virus scanners and spam filters to ensure the mail received is safe and relevant to you. SeaMail ensures that all communications are sent in an encrypted and secure manner, ensuring that your data is safe and that you comply with data protection legislation.

SeaMail automatically compresses the messages before connection in both directions. Files can be compressed up to as much as 80% thereby saving directly on airtime costs. Full duplex transmission allows you to receive the same amount of data from ashore at the same time as sending data. This reduces the time online.

Having been developed for use over multiple connections, SeaMail is compatible with VSAT, Ka, Ku band circuits, Inmarsat, Iridium, Thuraya, GSM and Wifi. Our ability to operate independently of airtime providers allows you to use SeaMail with your choice of maritime airtime provider.

Work offline and only connect for the time you need to send and receive data, saving on airtime costs.
