Outlook key-account silence-gap detector and re-engagement alert

Not every cooling signal is an angry email; often the relationship goes silent. This workflow detects the absence of reply, the silence gap, on key accounts. It learns each thread's typical response cadence, then flags conversations where the contact has stopped replying for noticeably longer than usual, especially ones that were previously positive. The owner gets a Teams alert with the last exchange so they can re-engage before the deal goes cold.

Reach for this when ghosting is your churn signal rather than complaints, common in mid-funnel deals and quiet renewals. It catches the accounts that disappear instead of objecting.

A recurring schedule scans the monitored Outlook mailboxes for active threads on key accounts. For each thread it computes the time since the contact's last reply and compares it to that thread's established cadence baseline. A logic step flags threads that have exceeded their normal gap and were warm before stalling. The flow uses Hugging Face to confirm the pre-silence tone was positive, avoiding alerts on already-dead threads. Qualifying threads produce a Teams re-engagement alert to the owner with the contact, the gap length, and the last message snippet.
