This card appears for contacts, companies, and opportunities and, based on both the frequency and duration of tracked email activity against either the specific contact, all contacts within the company, or the contacts on the opportunity in question, displays the following:
The last time the coworker received an email from an associated contact (“Last Contacted”).
The collective number of months/years the coworker has been exchanging emails with the contact (“Relationship Length”).
This card is especially useful for quickly determining which of your coworkers to get in touch with regarding a specific contact, company, or opportunity, as they have the most interaction with the record in question.
