Unreachable contacts are not a live list
Unreachable contacts are not a live SMS list. Hygiene % = (total − unreachable) ÷ total × 100. Type unreachable and total list.
Pair: List hygiene rate on Subscriptions. Growth: list growth vs opt-out. STOP: SMS stop vs MIT.
What you type
Unreachable — contacts the ESP marks unreachable / invalid / landline-blocked in the snapshot.
Total list — total SMS list size in the same snapshot.
Hygiene % = reachable ÷ total. Unreachable % = unreachable ÷ total. Scrub or re-permission when hygiene % is thin — do not invent a hygiene chip.
What not to do
Do not invent hygiene %. Do not mix opt-outs into unreachable without a rule. Do not treat suppressions as reachable. Do not bid SMS volume on a dirty list.
