Bring Together Email, Calendaring and Enterprise Applications

Zimbra is an enterprise-class email, calendar and collaboration solution built for the cloud, both public and private. With a redesigned browser-based interface, Zimbra offers the most innovative messaging experience available today, connecting end users to the information and activity in their personal clouds.

Enhance the End User Experience with Zimlets

  • New functionality may consist of simple hovers (view maps, calendar schedules) or entirely new application tabs (Zimbra Social)
  • Zimlets can call 3rd party data sources (WebEx) or internal back office systems (CRM)
  • Administrators configure which Zimlets are available to users and they can further refine their usage preference within the deployed set

Zimlets in Action

View Calendar Email

Hovers are simple yet powerful ways to save time- if someone sends an email suggesting a meeting date simply mouse over to preview your calendar on that day.

Address and Map Preview

This useful hover identifies physical addresses in email message bodies and renders them as maps.

Google Translate

Global organizations often receive email in non-native languages- this tool automatically previews and translates messages; allowing a user to reply. Bar

This Zimlet cross-references email senders / recipients in SFDC and provides contextual options to add Leads or append messages sent to Accounts & Opportunities.


It’s no longer necessary to open WebEx to schedule a conference- it’s done for you and the meeting information is included in the Calendar invites you send.


Smartsheet customers can access their spreadsheets and Gantt charts within Zimbra; milestones appear in Zimbra Calendar that you can share with peers.


Save time by aggregating and managing social networks like Facebook inside Zimbra instead of a desktop client; works anywhere on any computer.

Build Your Own

Using freely available reference Zimlets, Zimbra and 3rd party APIs, new Zimlets can be quickly built and deployed tailored to the specific day-to-day workflows which need to be streamlined and managed from within Zimbra.

For more information please see the review the Zimbra Wiki on Zimlets and the Zimlet Developers Guide for details about developing and deploying Zimlets.

Explore the Zimbra Community and Gallery

Zimbra has a large open source Community that can provide guidance on how to extend Zimbra functionality as well share code based on Zimlets that have been contributed to the Community. An excellent resource for more information is the Zimbra Forums where there are areas dedicated to development and Zimlets.

Another excellent resource for both finding and sharing Zimlets and other custom Zimbra add-ons is the Zimbra Gallery. Zimbra customers and Community members often place their finished creations here for the Community to leverage for their own deployments.
