What does the auto-refill monthly limit do?

The monthly limit is the circuit breaker in your Valid Email Checker auto-refill setup. It caps how many times the system can fire a refill within a single calendar month. Once you hit the cap, auto-refill disables itself for the rest of the month and you have to choose: re-enable it manually, buy credits manually as needed, or wait until the 1st of next month for the counter to reset.

Why the cap exists

Auto-refill, by definition, takes the human out of the loop. That is the whole point — credits land when you need them without you clicking anything. The trade-off is that a misconfigured threshold (set too high), a bursty traffic pattern, or a runaway API integration could fire refill after refill in a short window and rack up a much larger bill than you intended. The monthly limit is the safety net against that scenario. Hit the cap and the system pauses itself, giving you a chance to inspect what is happening before more money leaves your card.

Range, default, and how to pick a value

• Minimum: 1 refill per month
• Maximum: 30 refills per month
• Default: 3 refills per month
• Reset: counter resets to zero at 00:00 UTC on the 1st of every month

A new account should default to 2 or 3 while you get a feel for how often refills fire under your actual usage pattern. If you find that the cap is being hit every month and you genuinely need more refills, raise it — 5, 10, even 15 is fine for high-volume users. If you find that you are nowhere near the cap, leave it at 3; the lower the cap, the better the safety net.

What happens when you hit the cap

1. The final refill that brings you to the cap fires normally and credits land in your account.
2. Immediately after that refill, the auto-refill toggle in the dashboard header switches off automatically.
3. A blue info icon appears next to the toggle with the tooltip "Auto-refill was automatically disabled after reaching your monthly limit."
4. You receive an in-app notification (and an email, if you have email alerts on) explaining what happened.
5. Until the 1st of next month — or until you manually re-enable — no further refills fire. You can still buy credits manually anytime.

Re-enabling before month end

If you want auto-refill back on before the calendar rolls over, click the toggle again, confirm the settings modal, and save. The toggle turns green and the system resumes watching. The counter does not reset — it keeps counting from where it was, so a second cap-hit in the same month is possible. Re-enabling is the right call if your usage forecast for the rest of the month justifies it; raising the cap is the right call if the cap is consistently too low for your real workload.
