RUNBOOK · sender/cant-send-limit-exceeded3 FIXES
// quick answer
Sender blocks campaign sending when your active subscribers exceed the plan or you run out of monthly email credits. Remove inactive subscribers (the count updates hourly) or upgrade; email credits reset at the next billing cycle.
Most likely fix: Remove subscribers to get under the limit

FIX 1Remove subscribers to get under the limit

- 02Delete them; the active count recalculates every hour
- 03Retry the send
