Low ongoing ownership costs

Running MDaemon on your own server can offer significant savings over cloud-based mailbox services. 

Instead of paying a fixed recurring subscription per user, the only ongoing MDaemon costs are optional annual maintenance and support renewals.

Renewals are a fraction of the cost of new licences, making the total ownership costs very competitive indeed over two or more years.

Suitable for on-premise or cloud hosting

Install MDaemon at your office using your own hardware or use a cloud hosting provider such as Amazon AWS or Microsoft Azure.


Low system requirements and support for all modern desktop and server versions of Windows make MDaemon well suited to running on-premise, particularly if you already have suitable hardware on-site.


Reducing your hardware footprint? Hosting MDaemon using Amazon or Microsoft costs less than you may think, and offers additional benefits including high-speed bandwidth and physical security.


Quick and easy to recover in the event of an issue 

MDaemon uses an uncomplicated, flat file architecture which means you're not relying on a database that might become corrupted, and that creating a back up suitable for disaster recovery is as easy as copying the main installation folder to an appropriate location.

Simply use any scheduled backup software (such as BackupAssist) to create an automated backup routine that'll give you the ability to have your business back up and running again in no time if trouble strikes.
