I like the calendar link feature. It's nice keep this link in my email signature. This cuts out the back-and-forth of scheduling, since clients can use the link to directly access my calendar

Now that we've got our settings right, the event syncing process happens seamlessly and reliably. Cirrus offered the most sophisticated event syncing options of all the integrations we considered. We appreciate that it's a set it and forget it type deal - once users are onboarded there's no further maintenance required. The sidebar is a helpful way to quickly edit or navigate to the Salesforce event. All in all, a strong integration.

The imbedding of Cirrus into gmail. The popup on the right side of the screen should make it easy to use to upload emails to salesforce. I do also like the "add contact" feature
