Fine-tuned configuration - comprehensive reports

Full control of email

Dualog® Business Mail allows companies to set individual size limits for each user and carrier, giving a prioritised and controlled email flow. The vessel side software is configurable from anywhere, and our web portal gives complete access to all communication sessions, data transfer statistics and history. Management reports give an in-depth overview of the fleet status and help companies make qualified decisions based on real-time data. If communication is down, users can still read their email history. The service utilises automatic compression and decompression of all transferred data to reduce airtime costs. 


Choose your email domain

The service makes it easy to set up email addresses with your specific domain. There is also the option to create your subdomains to allow for any corporate configuration or policy.
