   The dormancy logic in https://github.com/marclou/mailcheap (lib/cleanup.js) is worth copying closely:

   • Criteria: a contact goes dormant only if they ignored at least N issues (default 6, range 2–100) and at least D days have passed since their last sign of life (default 180). "Last sign of life" is the max of last engaged, last open, last click, confirmed and subscribed dates. Each send increments an ignoredIssues counter, and any open, click, confirm or resubscribe resets it to 0.
   • Runs at send time, no cron needed. Contacts who qualify get the "still want this?" email instead of the issue. After 14 days with no response they become dormant, and the update re-checks ignoredIssues > 0 to avoid racing with a late engagement. This matters here because SendLit's background loops run on every API instance.
   • "Keep me" link: signed, valid for 90 days (longer than the 14-day window, so a late click still revives the contact), rate-limited. The re-engagement email has no tracking, so a machine open can't count as a "keep".
   • Separate stats for re-engagement emails, so the issue's open rate isn't diluted. Their bounces and complaints still count toward Auto-pause broadcasts and sequences on high bounce or complaint rates #25.
   • Preview in the send dialog: how many contacts will get the issue, the last-chance email, or be skipped.
   • Order: send to the most engaged first and re-engagement emails last.
   • Dependencies: this needs bot/MPP filtering (Filter bot, security-scanner and Apple MPP opens and clicks #37), or nobody ever looks dormant. Leaving dormant contacts out could use the exclude filter (sequences.excludeFilter is stored but never applied when sending #41). Historic engagement from the CSV import (CSV contact import and export #38) can seed the counters. The per-provider stats overlap with Deliverability report, mailbox-provider breakdown and subscriber growth chart #39.
