Pricing
Buy credits as you need them, or take a monthly plan at 15% less for the same credits. Either way, credits never expire and you only pay for definite answers.
| Credits | Price | Per address |
|---|---|---|
| 1,000 | $5 | $0.00500 |
| 10,000 | $25 | $0.00250 |
| 50,000 | $89 | $0.00178 |
| 100,000 | $139 | $0.00139 |
| 500,000 | $549 | $0.00110 |
| 1,000,000 | $949 | $0.00095 |
Free tier: 100 credits every month, no card required.
Monthly plans cost 15% less
If you verify every month, a plan gives you the same credits for 15% less than pay as you go. Unused credits roll over while the plan is active.
| Credits a month | Monthly plan | Same credits pay as you go |
|---|---|---|
| 1,000 | $4 a month | $5 |
| 10,000 | $21 a month | $25 |
| 50,000 | $76 a month | $89 |
| 100,000 | $118 a month | $139 |
| 500,000 | $467 a month | $549 |
| 1,000,000 | $807 a month | $949 |
Plan prices are the pay-as-you-go tier less 15%, rounded to the nearest dollar. A plan credit is billed exactly like a pay-as-you-go credit: unknowns and duplicates cost nothing.
Pick pay as you go for a one-off cleanup or a migration. Pick a plan if you run bulk list cleaning every month or verify signups in real time through the API, where the volume is steady and the 15% adds up.
Why unknowns are not billed
It is a pricing decision that follows from the product argument.
An unknown means the receiving server would not give a straight answer. It throttled the check, greylisted it, or refused to discuss recipients with a stranger. That is a different thing from a catch-all, where the server did answer and the answer told us something true about the domain.
Charge for that and the honest verdict becomes the expensive one. Any vendor billing for unknowns has a quiet incentive to resolve ambiguous addresses to valid instead of labeling them, which makes the accuracy figure look better and your bounce rate worse.
Bouncer, Kickbox, Reoon and Emailable all decline to bill unknown results too. It is becoming the norm in this category, and the vendors who say nothing about it are worth asking directly.
What counts as a credit
| Situation | Charged? |
|---|---|
| Address returns valid or invalid | Yes, one credit |
| Address sits on a catch-all domain | Yes, one credit |
| Address comes back unknown | No |
| Duplicate inside the same upload | No |
| Row rejected on syntax alone, before any lookup | No |
| Request that ends in an error, or is rate limited | No |
| Any call made with a sandbox key | No |
| Re-checking an address you checked before | Yes, because the answer can change |
A catch-all is billed because it is a real finding: the domain is configured to accept everything, and knowing that changes how you send.
Credits never expire
Kickbox and Hunter both expire unused credits after twelve months. If you clean a list twice a year, that single clause can matter more than the headline rate.
Ours stay until you spend them. Buy for a migration, use half, come back next year and the rest is still there. The credit expiry answer compares how other verifiers handle it.

Pricing questions
Is there a monthly subscription?
Yes. A monthly plan costs 15% less than the same credits pay as you go, and unused credits roll over while the plan is active. Pay as you go stays open to everyone with no minimum, and the free tier of 100 checks refreshes every month.
Do credits expire?
No. Pay-as-you-go credits stay until you spend them. Kickbox and Hunter both expire unused credits after twelve months.
What happens if I run out mid-upload?
The job pauses rather than failing. Top up and it continues from where it stopped, and nothing already verified is charged twice.
Do you charge for catch-all results?
Yes, one credit, because a catch-all verdict is a real finding about the domain. Unknowns are different: there we established nothing, so there is nothing to bill for.
Can I get a refund on unused credits?
Credits never expire, so the usual reason for wanting one does not arise. If you need to talk about a specific case, write to us.
