Email Finder Tools: What a Credit Actually Buys

A credit is a lookup, not an outcome, and the size of one varies by a factor of twenty between the tools on this page. Comparing finders by price alone is therefore close to meaningless: the only comparison that survives contact with a bill is what one credit buys and whether the ones you do not spend survive the month.

Every figure below comes from the vendor's own pricing page or its own credit documentation, read on 24 September 2026. Where a vendor does not publish the unit, this page says so rather than estimating it.

The unit, side by side

Read the phone column. Apollo charges eight credits for a number and one for an address; lemlist charges twenty and five. Both are a ratio rather than a price, and the ratios are different — four to one at lemlist, eight to one at Apollo. A team that needs numbers as often as addresses will find those two tools much closer together than their credit counts suggest, and a team that only wants addresses will find them much further apart.

The sentence most vendors leave out

Snov.io's knowledge base says what the others do not. It charges 1 credit for a "green" email — verified as valid — and 1 credit for a "yellow" one, which it describes as an address it "couldn't fully verify" but which "may still be deliverable". It charges nothing for a "gray" result where no address was found, and nothing for a "red" one known to be dead.

That is worth reading twice, because it is the thing that turns a credit allowance into an estimate. A thousand credits at Snov.io buys a thousand lookups of which some proportion — undisclosed, and dependent on your target market — are addresses it is not confident about. The policy is fair. The point is that it is the only one of the five that tells you.

Apollo takes the opposite approach and says so: "You're only charged credits for email addresses that Apollo can verify." Given the same allowance, an Apollo credit is therefore worth more than a Snov.io credit in confidence terms, and Snov.io's is worth more in rollover terms. Which trade you prefer depends on whether your constraint is budget or list quality.

Rollover is where the real money is

Outbound work is lumpy. A month spent building one big list and a month spent writing to it consume completely different amounts of lookup. What happens to an unused allowance therefore matters more than the headline rate for most small teams.

• Apollo is the strictest. Its own words: "Your credits expire at the end of each billing cycle. Credits do not roll over into the following billing cycle or upon renewal." On an annual plan the whole year's allowance unlocks at the start — Basic's 30,000 per seat — and whatever is left when the year ends is gone.
• Snov.io is the most generous. Its documentation says unused credits roll over while the subscription stays active, on both monthly and annual billing.
• lemlist's enrichment add-on is described on the pricing page as "Pay per success, with unlimited credit rollover" at $20.00 a month, or $16.00 on the yearly term, for 2,000 credits.
• Instantly sits between them: credits expire two months after purchase on monthly plans and a year after purchase on annual ones.

For a team that researches in bursts, Apollo's expiry rule can quietly cost more than its price advantage saves. For a team that looks up a steady few hundred records a month, it costs nothing at all.

Hunter, and a note about currency

Hunter is the best-known standalone finder and is not linked as a partner on this site, because nobody here has read its partner terms. It is named on merit and its links pay nothing.

Its pricing page served euros to a browser configured as a United States visitor, with no currency control offered, so its figures are recorded in euros and are not converted here. On the yearly panel, which is the one the page opens on, Starter is 34€ a month with "588€ 408€ billed yearly" and 24,000 credits a year. On the monthly panel the same plan is 49€ a month with 2,000 credits a month.

Those reconcile cleanly — 49€ across twelve months is 588€, and 2,000 credits across twelve months is 24,000 — but the headline a visitor sees first is the annual rate wearing a "/month" caption, which is the same trap lemlist and Apollo set. What Hunter's page does not state anywhere is how many credits one lookup costs, so this page does not say.

Working out what you will actually spend

The arithmetic is simple once the unit is known, and it is worth doing before choosing. Take Apollo's Basic plan at $49.00 per seat per month on the annual term — $588.00 for the year — with 30,000 credits granted upfront.

If every credit goes on email addresses, that is 30,000 addresses at about two cents each. If every credit goes on phone numbers at eight apiece, it is 3,750 numbers at about sixteen cents each. Same plan, same money, an eightfold difference in what arrives, decided entirely by which field you click.

Now apply the expiry rule. A team that uses half its allowance has paid $588.00 for 15,000 addresses at about four cents each, and the other half has gone. Nothing about that is hidden — Apollo publishes all three facts — but no pricing page puts them in the same sentence, and the full picture is on the Apollo review.

The part credits cannot buy

A verified address is a technical fact: mail sent to it will probably arrive. It is not a permission. The ICO's guidance says outright that "you cannot assume that simply because an individual's personal data is in the public domain they are agreeing to it being used for direct marketing purposes", and every one of these tools is in the business of finding personal data in the public domain.

More concretely, obtaining a record from a finder starts a clock. Where personal data comes from a source other than the person, the ICO requires privacy information to be given "within a reasonable period of obtaining the data and no later than one month from the date of collection". Buying the credit is the collection. The rules, from the regulators works through what that means, and the sending platforms that sit on top of these databases are compared in the platform comparison.
