atmail suite


atmail suite comprises version 8 of our webmail interface, an API Server, a DAV server and a native mobile app for iOS (android coming soon), representing a complete technology redesign for our webmail product. The responsive, intuitive UI has been developed to the latest standards in user-experience design and browser technology. This pairing of modern architectures and design methodologies results in an incredibly intuitive and fast email experience.

Private and secure on-premises email

  • Your customers can download the atmail app from the Apple App Store (Google Play coming soon) and connect to the API server you host on-premises

atmail mail server


Our mail server redefines the delivery of atmail’s core services providing a highly modular and scalable solution for mass installations, leveraging an automation engine to increase the ease and simplicity of the deployment and configuration of IMAP, SMTP, ManageSieve, Monitoring, AV and AS servers on demand.

When paired with atmail suite, the full stack allows for incredibly easy domain management (users, settings, groups, domains, aliases and branding per domain).

Please Note: The atmail DAV server is an optional plugin for either atmail suite or atmail mail server. If deployed, it is deployed with either product but not both.
