Daily sending cap reached: distinguish expected waiting from a fault

Define the decision

Capacity exists at multiple levels. A campaign can have unused allowance while the selected mailbox or workspace cannot send more. Visible successful sends may also differ from the usage considered by delivery controls when work has been reserved or its outcome remains uncertain. Start with the limiting constraint, not the largest number on the dashboard.

Work through the procedure

1. Record the selected sender and the configured campaign and workspace limits. Include other campaigns sharing the same resources.
2. Compare the relevant day's usage with each limit using its configured reset timezone. Do not assume the browser's midnight resets all budgets.
3. Check whether pending reservations or uncertain attempts explain a discrepancy between successful messages and reserved usage.
4. If the cap is behaving as intended, plan the next allowed window or reduce new enrollment demand. Escalate unexplained usage with a timestamped example.

Worked example

The following is a synthetic example for this procedure, not a customer result or performance benchmark.

Illustrative budget review
Campaign allowance remaining: 20
Workspace allowance remaining: 0
Selected mailbox otherwise connected
Decision: campaign still waits
Before increasing anything: review shared demand, reset zone and uncertain attempts

Read the result

The smallest effective constraint determines whether this attempt can proceed. Increasing the campaign allowance from 20 to 100 would not resolve an exhausted workspace budget. Nor does an application allowance override the provider's own restrictions. Treat capacity planning and provider acceptance as separate checks.

Check before moving on

1. Include follow-ups already due when forecasting tomorrow's demand.
2. Confirm the next allowed window after the relevant reset, especially around excluded days.
3. Keep a record of intentional limit changes so later volume differences have an explanation.

Limits and next action

There is no universally safe daily volume in this worksheet. Zintara's current engine applies delivery budgets and selected-account checks; provider policies remain independent. Do not rotate identities or raise limits merely to push through an unexplained provider rejection. Resolve the cause and recipient suitability first.
