Quiet hours can mute the rebill SMS
SMS quiet hours mute sends. CRM rebill / dunning often fires on one hour. If that hour sits inside quiet, the whole cohort is muted. Type quiet start, quiet end, rebill hour, and cohort.
Pair: Quiet hours vs rebill on Subscriptions. Cap capacity: SMS cap vs rebill cohort. Keyword: STOP vs MIT.
What you type
Quiet start / end — platform quiet-hours window in local hours 0–23 (wraps midnight when start > end).
Rebill hour — hour the CRM / flow schedules the rebill or dunning SMS (0–23).
Cohort — profiles that SMS should hit before the MIT / dunning action.
If rebill hour is inside quiet, missed sends = cohort. Otherwise zero. Move the send hour or narrow quiet — do not invent deliverability to shrink the mute.
What not to do
Do not invent an open rate. Do not treat STOP keyword volume as quiet-hours mute. Do not mix email quiet rules into the SMS clock. Do not ignore midnight wrap when start > end.
