Atmail Plugins

Extend Your Email to New Possibilities

Atmail plugins are an easy way to customize your users' Atmail experience without editing any core Atmail code (making upgrades easy). Read more on developing your own plugins.

Atmail includes a comprehensive JSON API to access email, calendaring & contact data, allowing you to build this data into your own applications, create mobile interfaces, mashup to a portal and more.

Built an existing Atmail plugin or mashup? Contact us, we love to hear what our end users are building!

Atmail Mashups

While Atmail plugins allow you to easily extend and modify Atmail's core functionality, another cool feature of Atmail is the JSON API which enables mashups by providing Atmail's email, contact & calendar data into your application.

The JSON REST API allows easy access to a user's Atmail data which can then be incorporated into your portal or other applications. In fact, the entire Atmail Mobile UI it built using the REST API.


  • Display unread emails
  • Fetch all recent email from a folder
  • Display Contact information
  • Display Calendar events
  • Add, Delete and Modify Calendar events and Contacts

Please note you need an active session on the Atmail Demo server to try these demos. You can create a session by launching a WebClient Demo session, then returning to this page to try the mashups.
