What does "Aggressive" auto-refill timing do?

Aggressive is the fastest of the three auto-refill timing modes in Valid Email Checker. When you pick Aggressive, the system fires the refill on the very next monitoring tick after your balance crosses the threshold — which is effectively immediate. There is no built-in delay between detection and the charge attempt. If the threshold is hit at 14:32:10, the refill is queued for the next tick and the charge typically lands within a minute.

What "next tick" actually means

The monitoring job that watches balances runs on a one-minute cron schedule. When that job runs, it pulls the list of users whose auto-refill is enabled, checks each account total balance against the threshold, and queues any that have crossed. With Aggressive timing the delay between detection and the actual processor call is zero milliseconds — the very same monitoring run that detects the drop also dispatches the refill. End-to-end, the time from "balance crosses threshold" to "credits in your account" is usually under 60 seconds.

When Aggressive is the right call

• You run a customer-facing form that verifies emails on submit, and a "you ran out of credits" pause would visibly break the form for real visitors.
• You have a steady API stream from a CRM, marketing platform, or your own backend, and any stall in verification would back up the upstream queue.
• You run bulk uploads that are large enough to drain a non-trivial percentage of the threshold in a single job. The faster the refill, the less risk that bursty consumption hits zero between ticks.
• You have multiple integrations firing at once — a few minutes of delay multiplied across them adds up to noticeable downtime.

Trade-offs you accept by picking Aggressive

The price of speed is that you have no realistic window to cancel a refill once the threshold is crossed. If you cross at 14:32:10, the refill fires by 14:33 and the charge has already gone through. If you wanted to intervene — say, you decided to buy a one-off larger package instead, or pause auto-refill for the month — you have to do it before the threshold is hit, not after. Most users do not need this kind of intervention window, which is why high-volume teams pick Aggressive without a second thought.

How Aggressive interacts with the monthly limit

Aggressive timing does not change the monthly refill cap. Even with the fastest timing mode, the system stops refilling once you hit your configured monthly limit (default 3). After that the toggle auto-disables and you have to re-enable manually. So Aggressive is "as fast as possible up to the cap," not "unlimited refills."
