Improving User Experience of Email Gateway using Cisco Success Network

Overview

You can use the Cisco Success Network (CSN) feature to send your email gateway and feature usage details to Cisco. These details are used by Cisco to identify the email gateway version and the features activated but not enabled on your email gateway.

The ability to send your email gateway and feature usage details to Cisco helps an organization to:

  • Improve the effectiveness of the product in user networks by performing analytics on collected telemetry data and suggesting users with recommendations using a digital campaign.
