On setup, IMS analyzes your email history to extract contacts that aren’t in your address book and rank all of your contacts by email volume. (For more detail on our patent pending prioritization process, see ClearContext Design: Contact Analysis and Maintenance).
Over time, email usage patterns change and automatic contact priorities can become stale. I suggest you re-run Contact Analysis every six months or so to ensure prioritization accuracy. This process will refresh all contact priorities automatically set by IMS without adjusting any contact priorities that you have manually set via the contact record. To re-run the process, go to ClearContext > Options > Analyze Contacts.
For more information on contact prioritization, see our User Guide.
