A row stuck on `sending:` = check by hand. **Skip** marks the draft skipped (and ends the sequence for a follow-up). A draft is **blocked** if the lead opted out or the stage does not match the message type.\n\n**Follow-ups (weekdays 9:00).** For leads in stage *Contacted* with no reply and a follow-up date reached, Claude drafts the next follow-up (cadence in `followUpDays`, default 3, 5 and 7 days). The draft waits for approval, and the owner gets one digest e-mail. When the last follow-up is old enough without reply, the lead moves to *Nurture*.\n\nAny reply (Template 3) or booked meeting (Template 4) stops the sequence.",
