The Rover IDX CRM now has two offerings. Dashboard Lite and Dashboard Full Featured
The Dashboard Lite allows your to manage contacts. You can see who has been on your site, when automatic property emails were sent to them, and also send them emails
The optional Dashboard Full Featured CRM adds features on top of the Dashboard Lite. You can add Notes and Tasks. You can Tag contacts to better organize your lists.
And you can view contact activity - like what properties they've viewed, what searches they've saved, and when they were last on the site.
