Verification credits and runs
Verification is prepaid. You buy credits, and a check spends one credit for each address it gets a real answer about. Credits are separate from your subscription and they do not expire.
This page covers buying them and running a check. For what the verdicts mean and what each one costs, see email verification.
Buy credits
Section titled “Buy credits”- Go to Verification, then select Buy credits on the Overview.
- The Buy verification credits screen opens, with your Balance at the top.
- Under Buy more, drag the slider to the number of credits you want.
- Check the Total, then select the Buy button, which names the amount you chose.
- You are taken to Stripe to pay. When you come back, a banner confirms the outcome.
The slider runs from 1,000 to 25,000 credits, in steps of 100, at a flat $0.01 per credit. So the smallest purchase is $10 and the largest is $250. The total updates as you drag, and it is priced from the same figure the checkout charges, so the number you see is the number you pay.

Two things to know before you go looking
Section titled “Two things to know before you go looking”Buying is desktop only. Choosing an amount and paying is consequential work, so on a phone the panel is replaced by one line: “Choose an amount and pay on desktop.” Your balance and any warnings still read perfectly on a phone. Only the buying moves.
Only an Owner or Admin can buy. A Member sees the balance but no purchase panel.
The banners you may see
Section titled “The banners you may see”| Banner | What it means |
|---|---|
| Credits on the way. Refresh if your balance hasn’t updated yet | Payment went through. The balance follows a moment later |
| Purchase cancelled. You were not charged | You backed out at Stripe. Nothing happened |
| Credits running low | You are under the low-balance mark. The exact number is in the notice |
| No credits yet. Buy some below | Your balance is zero |
The quote comes before the spend
Section titled “The quote comes before the spend”Wherever a check can be started, you see the same three-part flow, and no credit moves until the last step.
- A free count. A line telling you how many people in this list, import, or audience can be checked now. Counting costs nothing.
- Check them. Selecting it opens a confirmation, not a check.
- The quote. The confirmation reads the numbers back to you: “Checking N people costs N credits. No-answer checks are never charged.” Confirm and the run starts. Cancel and nothing has happened.

When your balance does not cover it
Section titled “When your balance does not cover it”You are never blocked, and you are never silently cut short.
If your balance covers some of the addresses, the quote says exactly that: the full cost, your balance, how many will be checked now, and how many are left over and need a top-up. The confirm button changes to read Check the first N, so you know precisely what you are agreeing to.
If your balance covers none of them, there is nothing to confirm, so the offer changes to a Top up credits button instead. Nothing is lost. Come back after buying and the count is still waiting.
Follow a run
Section titled “Follow a run”A check runs on the server, not in your browser. You can close the tab, come back, and see its real state. Nothing is lost by walking away.
A run passes through these states:
| State | What you see |
|---|---|
| Queued | “Getting ready to check N addresses.” |
| Checking | A progress bar, and “Checking N addresses” with a percentage when the checker reports one |
| Check complete | The verdict tally and the credits spent |
| Check failed | “No addresses were checked and you were not charged. Start it again.” |
Reading the summary
Section titled “Reading the summary”When a run finishes you get a Check complete panel with one tile per verdict, Alive, Dead, Risky and No-answer, and a line saying how many credits were spent, or “No credits spent.”
Under it sit the honest footnotes, when they apply:
- N reused for free (checked recently), addresses that already had a fresh result.
- N skipped for free (suppressed or invalid), the automatic weed-outs.
- N addresses not checked, your balance ran out. Top up to finish.
If there was genuinely nothing to do, the panel says so: “Nothing to check. Everyone was checked recently or has no valid address.”
Retry the no-answers, for free
Section titled “Retry the no-answers, for free”If a run produced any no-answers, a button appears: Retry the N no-answers for free. Under it, the promise in one line: “Only charged for the ones that now return an answer.”
It starts a new run over just those still-unanswered addresses. Addresses that answer this time cost their one credit as usual. Anything still undecided costs nothing again. A no-answer is often a temporary condition at the other end, so a retry an hour later is frequently worth it.
The history table
Section titled “The history table”Verification, then the Verifications tab, is the record of every check you have run, address by address. It is the human-readable partner to your credit ledger, so no credit spend is ever a mystery.
Once you have real history, four all-time figures sit above the table: Addresses checked, Credits spent, Valid found, and Running now. These count everything, not just the page you are looking at.
The table itself gives you:
- A status filter: All checks, In flight, Completed, Failed.
- A search box that matches the check’s label, so you can find the run over a particular list.
- Paging, with a rows-per-page control that is remembered for next time.
- Export CSV, which exports the whole filtered history, not just the visible page. It is only unavailable when the current filtered view is empty.
Each row shows what was checked and when, how many addresses, who started it, and its result. A finished run’s result reads as a compact tally, for example “120 alive · 14 dead · 6 risky”. An in-flight run shows Queued or Checking with its percentage, and updates as it goes. A failed run reads Failed, not charged. The credits column shows a dash until a run completes.
Rows with no-answers carry the same free-retry button here, so you can pick up an old run later.

Refunds and negative balances
Section titled “Refunds and negative balances”Credits are bought through Stripe. If a credit purchase is refunded or charged back, the reversed credits are taken out of your wallet. That can leave your balance below zero, and no further checks can run until you buy credits again.
A dispute later resolved in your favour does not put clawed-back credits back automatically. Get in touch and it is handled by hand.
