The short answer
- For a company domain, start with Hunter’s Domain Search; it offers role and source filters.
- For a known person, Hunter’s Email Finder API can return found or inferred addresses, with different verification verdicts.
- If you need employee discovery through Findymail, its Find Employees endpoint returns people without email; budget for the next step.
- Compare the route as well as the result: Hunter’s credit rules differ for individual and bulk domain searches.
Start with the input you have
Choose the lookup by the missing piece: a company, a known person, or a list to process. We compared documentation from Findymail and Hunter.
A domain search helps when you have a company but need to discover contacts. Hunter’s finding guide offers role and provenance filters for Domain Search. Its Email Finder instead starts with a known person and company.
For an API workflow, Hunter’s API documentation accepts a LinkedIn handle as an alternative input. It distinguishes found addresses from inferred ones, and a found-only endpoint excludes inferred results. A handle is a lookup key; it does not imply access to the address used to register a social account.
Findymail’s API documentation marks the old domain-role endpoint as deprecated. Its recommended Find Employees replacement returns people without email. On credit plans it charges per person returned, so finding an address is a separate step to plan and test.
Write down the input and desired output before comparing prices. A list of names can be useful for research while still leaving your team with address lookups to complete. For a bulk job, keep the original input beside each result so failed searches remain visible.
Compare the charge for each route
A credit only has meaning alongside the action that consumes it. Compare the same task on the actual plan and interface you intend to use.
| Product and route | Billing unit | Limit that matters | Control or output |
|---|---|---|---|
| Hunter all-in-one | Unified credits: finder 1; verifier 0.5; enrichment 0.2 | Individual domain: 1 per revealed email; bulk domain: 1 per 1–10 emails per domain | Domain Search reveals email addresses |
| Hunter Data Platform | Separate search and verification credit pools | Repeat requests use the applicable calendar-month window; separate bulk CSVs do not share the free duplicate rule | API supports found-only results |
| Findymail usage plans | Shared usage limits, rather than credits | Individual, Team and Scale concurrency caps: 25, 50 and 150; endpoint caps can be lower | Find Employees returns people without email |
| Findymail credit plans | Finder charged on success; verifier costs 1 verifier credit per request | Find Employees charges per returned person | Separate finder and verifier credits |

For example, Hunter’s credit guide charges one credit for each email revealed in an individual Domain Search. A bulk domain search charges one credit per one to ten emails per domain. Ten revealed addresses for one domain therefore use ten credits individually or one through that bulk rule.
Hunter’s duplicate rules track qualifying individual requests across a team. The free repeat window is the billing period for monthly all-in-one plans, and the calendar month for yearly plans and Data Platform. Separate bulk CSV uploads do not share that free duplicate rule.
Findymail’s pricing page separates prospecting subscriptions from reseller credits. It lists Individual at $99 per month, Team at $399 and Scale at $999, with different seats and usage. Do not attach reseller allowances to those subscriptions.
Hunter’s pricing page lists Starter at $34 per month on annual billing, with $408 billed yearly and 24,000 annual credits. Its Data Platform sells API credits separately. These prices do not make the two vendors’ units interchangeable.
Findymail’s API limits describe concurrency as simultaneous requests in flight. The documented plan caps are not requests per minute, and lower endpoint caps can apply. Get the usage allowance and renewal terms for your intended subscription before forecasting volume.
Keep the verdict with the address
Treat the address and its verification verdict as separate fields. A returned address may still need a decision before it enters a campaign.
Hunter’s verification FAQ distinguishes valid, invalid, accept-all, disposable and unknown results. Unknown checks consume no credits, and Hunter says verification cannot guarantee zero bounces. Accept-all and unknown are not valid verdicts.
Hunter’s Finder API can return valid, accept-all or unknown verification results. Its verifier response includes a verification date and may reuse checks up to a month old. Keep that date with the result when deciding whether to check again.
Hunter’s finding guide includes verification with Email Finder, while a new verification in Domain Search can cost separately. Record which action produced the verdict so the later check is included in your cost model.
Findymail’s bounce guarantee has conditions beyond a headline rate. It requires at least 1,000 B2B addresses sent within 48 hours of verification, with invalid-address bounces above 5%. Claims must arrive within 30 days, and support reviews compensation individually.
The email verification guide explains how to handle uncertain results and compare verification workflows. Decide who can release an uncertain result, and retain the reason for that decision.
Protect the handoff to your CRM
A useful result must reach the right owner with enough context to review it later. Test the actual destination before relying on a successful lookup.
Hunter’s export guide includes custom attributes alongside verification status and date, source and activity dates in saved-lead CSV exports. Its company export limit is 100 on free plans and 100,000 on paid plans; the guide gives no equivalent limit for people exports.
Hunter’s HubSpot integration guide says only a lead owner can manually sync their lead, even from a shared list. Existing leads need an explicit sync after connecting. Matching uses email, and record-level finding fills an empty email field.
Keep source and verdict next to each address in the receiving system. A saved-lead export is a different object from an unrevealed discovery result; decide which records need to be saved before the handoff. Review field mappings and ownership with the people who will maintain the list.
Run the same jobs in a trial
Use a representative set of controlled or consented records and keep the unsuccessful results. Run domain discovery separately from known-person lookup so each task has a clear denominator.
Use the software trial guide to assign an owner and agree on a pass condition before the trial. Keep the test records and the credit reconciliation with the decision.
Common questions
What is the best email finder for a company domain?
If role and source filters matter, start with Hunter’s Domain Search. Test your own domains and compare the bulk route if that is how you will run the work.
Can I find an email from a LinkedIn handle?
Hunter’s Email Finder API accepts a LinkedIn handle as an alternative input. It does not promise the email used to register the social account.
Does one credit always buy one email?
No. Hunter’s credit guide distinguishes individual domain reveals from bulk domain searches. Findymail’s usage plans use shared limits, while its credit plans have separate rules.
Is an accept-all result a valid email?
Hunter’s verification FAQ treats accept-all and unknown as distinct verdicts. Neither is a valid verdict, and verification cannot guarantee zero bounces.
Can I export verification status from Hunter?
Hunter’s saved-lead export guide includes verification status and date in CSV fields. Inspect the exported file and destination mapping before switching.
