For most small teams doing cold outreach, start with Hunter. At about 1.7 cents per found email it is the cheapest per result here, and you only pay when it finds one. If Hunter misses too many of your prospects, FullEnrich queries 25+ data providers in sequence and charges only for data it finds. Lusha is the better buy when you also need direct phone numbers. Whatever you pick, verify before you send, because a found email and a deliverable email are not the same thing.

No vendor or independent site we found publishes a hit-rate benchmark with a clear method, and we did not run one. So this list ranks tools by what each verified email costs on its published pricing, and the method section gives you a test you can run on your own prospects in an afternoon.

> **Key Takeaways**
>
> - **Hunter charges only for success.** Email Finder costs "1 credit per email found," and nothing if none is found. Starter is $34 a month billed yearly for 2,000 credits ([Hunter pricing](https://hunter.io/pricing), retrieved 2026-10-16).
> - **FullEnrich runs a waterfall across "25+ Sources"** at $0.055 per credit on the 1,000-credit tier. A work email costs 1 credit and a mobile number 10 ([FullEnrich pricing](https://fullenrich.com/pricing), retrieved 2026-10-16).
> - **Lusha is built around phone data.** A verified email costs 1 credit and a phone number 5 credits. Pro is $52.45 a month billed annually for 600 credits ([Lusha pricing](https://www.lusha.com/pricing/), retrieved 2026-10-16).
> - **Verification is cheap next to finding.** NeverBounce charges "$8 / 1,000 credits," under a cent per address ([NeverBounce pricing](https://neverbounce.com/pricing), retrieved 2026-10-16).
> - **Catch-all domains defeat every verifier.** NeverBounce classes them "Accept all (Unverifiable)" with a "use caution" recommendation ([NeverBounce result codes](https://www.neverbounce.com/help/result-codes), retrieved 2026-10-16).

## Finding vs verifying an email

An **email finder** takes a name and a company domain (or a LinkedIn profile) and returns a likely address. It either looks the person up in a database it has built, or it guesses from the company's naming pattern (firstname.lastname@, f.lastname@) and checks the guess.

An **email verifier** takes an address and asks the receiving mail server whether that mailbox exists, without sending an email. It returns valid, invalid, or unknown.

The gap between the two is the **catch-all domain**. Some company mail servers accept every address at the domain, real or not, so a verifier cannot tell whether jane.doe@ exists. NeverBounce calls these "Accept all (Unverifiable)" and recommends "use caution." Many such addresses are valid, but you cannot confirm which ([NeverBounce result codes](https://www.neverbounce.com/help/result-codes), retrieved 2026-10-16).

That is why "found" is the wrong number to compare. The useful number is **found and verified as valid**, divided into what you paid. Finders with a strong database return more valid addresses at catch-all domains. Pattern-guessing tools return more "unknown" results there.

## How to test hit rate on your own list

Hit rates depend on your market. A tool that does well on US SaaS companies may do poorly on German manufacturers. So the honest benchmark is the one you run on your own prospects. Here is a method that fits inside free plans and trials:

1. **Build a test list of 100 prospects** from your real target accounts: name, company domain, LinkedIn URL. Include some large companies and some under 50 employees, since small companies are often catch-all.
2. **Run the same 100 through each tool's free tier.** Free allowances as of 2026-10-16: Hunter 50 credits a month, FullEnrich 50 trial credits, Lusha 40 credits a month, Voila Norbert 50 credits, Seamless.AI 50 lifetime credits, and Apollo's free plan. Split the list in half if a tool's free allowance is short.
3. **Record three numbers per tool:** found, found and marked valid by the tool, and found but unknown or catch-all.
4. **Re-verify every found address with one independent verifier** (NeverBounce or Hunter's verifier) so the "valid" judgment is consistent across tools.
5. **Send a small, legitimate first touch** to the valid set from a warmed mailbox, and count hard bounces after 48 hours. Bounces are the ground truth.
6. **Calculate cost per valid email:** monthly plan price ÷ (credits × your valid rate).

If two tools tie, pick the one whose data you can push into your CRM or sequencer without copying and pasting.

## The 8 tools ranked by cost per verified email

| Rank | Tool | Entry paid plan (billed annually) | What one credit buys | Cost per found email | Charges on a miss? |
|---|---|---|---|---|---|
| 1 | [Hunter](https://hunter.io/pricing) | Starter $34/mo, 2,000 credits | 1 found email; 0.5 per verification | ~$0.017 | No |
| 2 | [Snov.io](https://snov.io/pricing) | Starter $39/mo, 1,000 credits | 1 found email or 1 verification | ~$0.039 | No (charged for valid or unknown results) |
| 3 | [Voila Norbert](https://www.voilanorbert.com/pricing) | Valet $39/mo, up to 1,000 leads | 1 successful find | ~$0.039 | No |
| 4 | [FullEnrich](aff:fullenrich) | Pro 1,000 credits at $0.055/credit (~$55/mo) | 1 work email; 10 per mobile | ~$0.055 | No |
| 5 | [Lusha](aff:lusha) | Pro $52.45/mo, 600 credits | 1 verified email; 5 per phone | ~$0.087 | Not stated on pricing page |
| — | [Apollo.io](https://www.apollo.io/pricing) | Basic ~$49/user/mo (third-party) | 1 credit per verified email | Depends on plan credits | No |
| 6 | [Seamless.AI](aff:seamless) | Basic ~$147/mo, 3,000 credits/year (third-party) | Email or phone reveal | ~$0.59 per credit | Not stated |
| — | [NeverBounce](https://neverbounce.com/pricing) | Pay as you go, $8 per 1,000 | 1 verification | $0.008 to verify | Verifier only |

Prices retrieved 2026-10-16. "Cost per found email" is plan price ÷ monthly credits at the entry tier, before any verification. Third-party figures are marked: Apollo's and Seamless.AI's pages did not show prices to an automated reader. Apollo is unranked because its per-plan email credit allowance is not published on the page we could read; NeverBounce is unranked because it verifies rather than finds.

Cheaper per credit is not the same as cheaper per valid email when you pay for a plan. Say you buy one month of each entry plan to work a list of 1,000 prospects. If Hunter ($34) returns 400 valid addresses, each costs 8.5 cents. If FullEnrich (about $55) returns 800, each costs about 6.9 cents, and your reps have 400 more people to contact. Those find rates are illustrations, not measurements. Run the test above to get your own.

## Hunter.io

**Best for:** small teams and founders prospecting at companies with a public web presence.

Hunter's pricing is the clearest here. Free has 50 credits a month. Starter is $34 a month billed yearly ($49 monthly) for 2,000 credits. Growth is $104 ($149 monthly) for 10,000 credits, and Scale is $209 ($299 monthly) for 25,000. Email Finder charges "1 credit per email found," the Verifier charges 0.5 credit, and failed verifications or misses cost nothing. Monthly credits do not roll over, while yearly plans give all credits up front ([Hunter pricing](https://hunter.io/pricing), retrieved 2026-10-16). Hunter also includes cold-email sequences, with 2,500 recipients per sequence on Starter.

**Not for:** teams that need mobile numbers, or prospects at small companies with little public footprint.

## Apollo.io

**Best for:** teams that want a prospect database, email finder and sequencer in one place, and will use all three.

Apollo's pricing page lists Free, Basic, Professional and Custom plans. Credits are pooled across the team, granted at the start of each billing cycle, and expire if unused ([Apollo pricing](https://www.apollo.io/pricing), retrieved 2026-10-16). Apollo's help center says verified emails cost 1 credit per contact, and that it does not charge email credits for contacts without known valid addresses. It refunds credits when an Apollo-verified email bounces within 30 days ([Apollo help](https://knowledge.apollo.io/hc/en-us/articles/6319289281805-Will-Apollo-Charge-Me-for-More-than-One-Email-per-Contact), retrieved 2026-10-16). Prices did not load for us. An April 2026 tracker lists Basic at $49 and Professional at $79 per user per month billed annually, with phone lookups at 8 credits ([Docket](https://docket.io/resources/research/apollo-pricing), retrieved 2026-10-16).

**Not for:** buyers who only need emails. You pay per user for a full sales platform.

## FullEnrich (waterfall across providers)

**Best for:** teams whose prospects are hard to find, such as outside the US, at smaller companies, or at catch-all domains.

[FullEnrich](aff:fullenrich) does not keep its own database. It queries "25+ Sources" in sequence and stops when one returns a result, which it then verifies. Pricing is per credit: the Pro plan starts at 1,000 credits a month at $0.055 per credit. A work email costs 1 credit, a personal email 3, and a mobile phone 10. A free trial gives 50 credits with no card. The company's position is "If we can't find the data, you don't pay" ([FullEnrich pricing](https://fullenrich.com/pricing), retrieved 2026-10-16).

FullEnrich also makes performance claims that are its own, not independently checked: an average find rate "around 80%" and "80% Of Catch-Alls Verified." Treat these as hypotheses to test on your list.

**Not for:** high-volume teams on prospects that Hunter already finds. You pay about three times as much per credit for coverage you may not need.

## Lusha

**Best for:** sales teams that call as much as they email.

[Lusha](aff:lusha) prices by credit: "Reveal verified email address – 1 credit" and "Reveal a phone number – 5 credits." Free has 40 credits a month. Starter is $37.45 a month billed annually ($49.90 monthly) for 400 credits a month. Pro is $52.45 ($69.90 monthly) for 600, and Premium is $299.95 ($399.90 monthly) for 3,400. On monthly plans, unused credits roll over up to twice the plan limit, while annual plans issue all credits up front and reset at the end of the year. Teams over 5 users are routed to sales ([Lusha pricing](https://www.lusha.com/pricing/), retrieved 2026-10-16).

At about 8.7 cents per email credit on Pro, Lusha is expensive for email-only outreach. Its value is that one tool covers both the email and the direct dial.

**Not for:** email-only campaigns at volume.

## Seamless.AI

**Best for:** teams that want a real-time search engine for contacts and are ready to sign an annual contract.

Seamless.AI's free plan gives 50 credits, a one-time lifetime allotment. Its pricing page did not load for us. A January 2026 review lists Basic at $147 a month billed yearly with 3,000 credits a year. Pro and Enterprise are quote-only ([Lindy blog](https://lindy.ai/blog/seamless-ai-pricing), retrieved 2026-10-16). By that figure each credit costs about 59 cents, the highest here, though a credit covers phone numbers as well as emails. Get a written quote with the per-credit rate and renewal terms before you sign. For a direct comparison with Lusha, see our [Lusha vs Seamless.AI](/blog/lusha-vs-seamless-ai) breakdown.

**Not for:** anyone who wants month-to-month billing or published prices.

## Snov.io and Voila Norbert

**[Snov.io](https://snov.io/pricing)** bundles finding, verifying and email campaigns. Starter is $39 a month on annual billing with 1,000 credits, 5,000 campaign recipients and unlimited team seats. Pro is $99 with 5,000 credits. One credit covers one email search or one verification ([Snov.io pricing](https://snov.io/pricing), retrieved 2026-10-16). Snov.io's knowledge base says it charges no credits when no email is found ([Snov.io knowledge base](https://snov.io/knowledgebase/what-is-a-credit/), retrieved 2026-10-16). Its [API docs](https://snov.io/api) say a credit is charged for valid (green) or unknown (yellow) results, so a share of what you pay for may be unverifiable. **Best for** small teams wanting one tool for list building and sequences.

**[Voila Norbert](https://www.voilanorbert.com/pricing)** is a plain email finder. Valet is $39 a month on yearly billing ($49 monthly) for up to 1,000 leads. Butler is $79 ($99) for 5,000, and Advisor is $199 ($249) for 15,000. All plans include unlimited team members, bulk and API use, and credit rollover. It gives 50 free credits and says "I count only successful email founds" ([Voila Norbert pricing](https://www.voilanorbert.com/pricing), retrieved 2026-10-16). Its separate verification service is pay-as-you-go at $0.003 per email up to 500,000. **Best for** bulk CSV lookups by people who already have a sequencer.

**Not for (both):** phone data. Neither is built for it.

## Cost per verified email

To get from "cost per found email" to cost per verified email, add verification and divide by the share that comes back valid.

**Worked example** at list prices retrieved 2026-10-16, for 1,000 prospects a month. The valid rates below are placeholders to show the math. Replace them with your own test results.

| Tool | Monthly spend for 1,000 lookups | If 50% come back valid | If 70% come back valid |
|---|---|---|---|
| Hunter Starter (found emails only charged) | Up to $34 | $0.068 per valid email | $0.049 |
| FullEnrich (1,000 credits) | Up to $55 | $0.110 | $0.079 |
| Lusha Pro (600 credits; needs ~2 months) | ~$87 equivalent | $0.175 | $0.125 |
| Add NeverBounce re-verification | +$8 | +$0.016 | +$0.011 |

How to read it: Hunter only charges for found emails, so if it finds 500 of your 1,000 prospects you spend 500 credits, not 2,000. The per-valid figures assume you buy the entry plan regardless of usage, which is how most small teams pay.

**Our picks:**

- **Lowest cost, prospects with a web footprint:** Hunter.
- **Hard-to-find prospects, international or catch-all heavy:** FullEnrich.
- **Calling plus email:** Lusha.
- **Database plus sequencer in one seat:** Apollo.io.
- **Bulk CSV finding without extras:** Voila Norbert.
- **Always:** re-verify with NeverBounce or Hunter's verifier before a first send to a new list.

## Frequently Asked Questions

### What is the most accurate email finder?

No independent benchmark with a published method was available when we checked in October 2026, and accuracy depends heavily on your market. Vendors publish their own figures; FullEnrich, for example, claims an average find rate around 80%. Run 100 of your real prospects through two or three free tiers, re-verify with one verifier, and compare bounces.

### Is there a free email finder?

Yes, with small allowances. Hunter gives 50 credits a month, Lusha 40 credits a month, Voila Norbert and FullEnrich 50 credits once, and Seamless.AI 50 lifetime credits. Apollo also has a free plan. That is enough to test a list of 100 prospects, but not to run ongoing outreach.

### Do I need an email verifier if my finder already verifies?

For a first send to a new list, yes. Finders verify at the moment of lookup, and addresses decay as people change jobs. A second check with a dedicated verifier such as NeverBounce costs under a cent per address and gives you one consistent standard. Keep catch-all results in a separate, smaller send.

### What is a catch-all email address?

A catch-all (or accept-all) domain is a mail server set to accept mail for any address at that company, so a verifier cannot confirm whether a specific mailbox exists. NeverBounce labels these "Accept all (Unverifiable)" and advises caution. Many are valid, but send to them in small batches and watch bounce rates.

## How this guide was researched

We read the pricing pages and help documentation of Hunter, Apollo.io, FullEnrich, Lusha, Snov.io, Voila Norbert and NeverBounce, plus independent pricing write-ups for Apollo.io and Seamless.AI where the vendor pages did not load, all retrieved on 2026-10-16. Tools were compared from documentation, pricing and public information, not hands-on testing. We did not measure hit rates, which is why the ranking uses published cost per email and the guide includes a test you can run yourself. LogicBalls may earn a commission from some links in this article, which does not change the order or the recommendations.
