Description

Detect messages where there are 2 or more previous threads, where all previous messages are self-replies from the same sender, a calendar invite attachment with no physical location or generic online-meeting location, and B2B Cold Outreach topic analysis. This pattern is observed as excessive unsolicited outreach with disruptive required intervention.
