It returns the most likely work address with a status. Most finders charge only when they find one. Keep verified results only, and send misses to a second provider. In our 50-person pilot, one provider found 36 emails and two providers together found 39 (78%). Verified 25 Oct 2026 · 7 ways to do it · 14 tools compared [ Cost at your volume ](#cost)[ Every way to do it ](#routes) 01 ## Every way to do it 7 routes, from code to no-code: who each one suits and the tools that run it. Open a route for how it works and where it goes wrong. 1. 1 ### A finder API Code Lists where one provider covers your audience. - [![](/_astro/hunter.C-TuEfmZ_1PWV4T.webp)Hunter](/tool-directory/enrichment/hunter "Hunter") - [![](/_astro/prospeo.deQVoOYK_Zg2G6l.webp)Prospeo](/tool-directory/sourcing/prospeo "Prospeo") - [![](/_astro/findymail.BKowYsnX_Z1blaX3.webp)Findymail](/tool-directory/enrichment/findymail "Findymail") - [![](/_astro/leadmagic.VYwz4sDG.svg)LeadMagic](/tool-directory/enrichment/leadmagic "LeadMagic") - [![](/_astro/forager.BYftcGLR_cJeBs.webp)Forager](/tool-directory/enrichment/forager "Forager") - [![](/_astro/apollo.DNg6-7d3.svg)Apollo](/tool-directory/sourcing/apollo-io "Apollo") - [![](/_astro/rocketreach.rwx2rnfO_Z2gCPob.webp)RocketReach](/tool-directory/sourcing/rocketreach "RocketReach") - [![](/_astro/lusha.BjP45Jap_Z1j2Qmy.webp)Lusha](/tool-directory/sourcing/lusha "Lusha") - [![](/_astro/people-data-labs.mXDEg2jz_ZmMub8.webp)People Data Labs](/tool-directory/enrichment/people-data-labs "People Data Labs") - [![](/_astro/ai-ark.BE60pifs_zupjQ.webp)AI Ark](/tool-directory/sourcing/ai-ark "AI Ark") How it works and where it goes wrongShow less Send a name plus company domain, or a LinkedIn URL, to one provider's finder endpoint. Read the email and its status or confidence before you use it. Pilot 50 rows first, because hit rates change from one audience to the next. **Where it goes wrong.** Treating a pattern-built address as a confirmed find. Some finders return a pattern-generated address with a score. In our Hunter test the result came back marked source\_type 'generated' and provenance 'inferred'. Filter on verified status. 2. 2 ### Verify as you find Code Outbound lists going straight into a sequencer. - [![](/_astro/prospeo.deQVoOYK_Zg2G6l.webp)Prospeo](/tool-directory/sourcing/prospeo "Prospeo") - [![](/_astro/findymail.BKowYsnX_Z1blaX3.webp)Findymail](/tool-directory/enrichment/findymail "Findymail") - [![](/_astro/leadmagic.VYwz4sDG.svg)LeadMagic](/tool-directory/enrichment/leadmagic "LeadMagic") - [![](/_astro/zerobounce.DMK7iQt0_Z4rXLd.webp)ZeroBounce](/tool-directory/verification/zerobounce "ZeroBounce") - [![](/_astro/ai-ark.BE60pifs_zupjQ.webp)AI Ark](/tool-directory/sourcing/ai-ark "AI Ark") How it works and where it goes wrongShow less Ask the finder for verified results only and accept nothing else. Prospeo takes an only\_verified\_email flag. Findymail and LeadMagic bill a find only when the email is valid. Re-verify the accepted list right before sending. **Where it goes wrong.** An email at the person's old company. Provider data can lag a job change, so we accept an email only when its domain matches the live current-employer domain. 3. 3 ### Waterfall Low code Lists where one provider tops out, and high-value contacts worth a second or third lookup. - [![](/_astro/fullenrich.jkZy8sVI.svg)FullEnrich](/tool-directory/enrichment/fullenrich "FullEnrich") - [![](/_astro/bettercontact.DR_th9s7_Z95XTP.webp)BetterContact](/tool-directory/enrichment/bettercontact "BetterContact") - [![](/_astro/clay.CHDKXtEw_Z20f3oS.webp)Clay](/tool-directory/data-platforms/clay "Clay") - [![](/_astro/apollo.DNg6-7d3.svg)Apollo](/tool-directory/sourcing/apollo-io "Apollo") - [![](/_astro/lusha.BjP45Jap_Z1j2Qmy.webp)Lusha](/tool-directory/sourcing/lusha "Lusha") How it works and where it goes wrongShow less Send each miss from provider 1 to provider 2, and stop at the first verified email. Buy it ready-made (FullEnrich, BetterContact, Clay's Work Email waterfall, Apollo's waterfall flag, Lusha's Data Waterfall) or build it from single providers. See the related waterfall job for the build. **Where it goes wrong.** Paying twice for one person. FullEnrich does not dedupe inside a bulk call, Apollo's waterfall email can cost 20+ credits, and LeadMagic may throttle accounts whose find rate falls below 10%, which its terms say includes use late in a waterfall. 4. 4 ### No-code / Clay No code Teams whose lists already live in Clay tables. - [![](/_astro/clay.CHDKXtEw_Z20f3oS.webp)Clay](/tool-directory/data-platforms/clay "Clay") How it works and where it goes wrongShow less Add Clay's Work Email waterfall column to a table, or pick one provider column. In the app on 25 Oct 2026 the waterfall showed about 1.1 data credits per row across 11 providers, and single providers 0.2 to 6 per row. **Where it goes wrong.** Two meters: data credits for the data and Actions for every run. Top-ups cost a 30% premium on Launch and Growth. 5. 5 ### Through an AI agent (MCP) AI agent Researching a handful of people while you work in an agent. - [![](/_astro/prospeo.deQVoOYK_Zg2G6l.webp)Prospeo](/tool-directory/sourcing/prospeo "Prospeo") - [![](/_astro/hunter.C-TuEfmZ_1PWV4T.webp)Hunter](/tool-directory/enrichment/hunter "Hunter") - [![](/_astro/findymail.BKowYsnX_Z1blaX3.webp)Findymail](/tool-directory/enrichment/findymail "Findymail") - [![](/_astro/leadmagic.VYwz4sDG.svg)LeadMagic](/tool-directory/enrichment/leadmagic "LeadMagic") - [![](/_astro/apollo.DNg6-7d3.svg)Apollo](/tool-directory/sourcing/apollo-io "Apollo") - [![](/_astro/rocketreach.rwx2rnfO_Z2gCPob.webp)RocketReach](/tool-directory/sourcing/rocketreach "RocketReach") - [![](/_astro/lusha.BjP45Jap_Z1j2Qmy.webp)Lusha](/tool-directory/sourcing/lusha "Lusha") - [![](/_astro/fullenrich.jkZy8sVI.svg)FullEnrich](/tool-directory/enrichment/fullenrich "FullEnrich") - [![](/_astro/clay.CHDKXtEw_Z20f3oS.webp)Clay](/tool-directory/data-platforms/clay "Clay") - [![](/_astro/ai-ark.BE60pifs_zupjQ.webp)AI Ark](/tool-directory/sourcing/ai-ark "AI Ark") How it works and where it goes wrongShow less Connect a finder's hosted MCP server to Claude and ask it to enrich a person by LinkedIn URL. Prospeo includes its MCP server on the Free plan. **Where it goes wrong.** One prompt can fan out into several charged calls, as Clay's MCP docs warn. Set credit limits where the vendor offers them (per key at Lusha and FullEnrich, per rep at Clay). 6. 6 ### Manual / UI No code A few lookups a week, or testing data quality before you buy an API plan. - [![](/_astro/hunter.C-TuEfmZ_1PWV4T.webp)Hunter](/tool-directory/enrichment/hunter "Hunter") - [![](/_astro/apollo.DNg6-7d3.svg)Apollo](/tool-directory/sourcing/apollo-io "Apollo") - [![](/_astro/lusha.BjP45Jap_Z1j2Qmy.webp)Lusha](/tool-directory/sourcing/lusha "Lusha") - [![](/_astro/prospeo.deQVoOYK_Zg2G6l.webp)Prospeo](/tool-directory/sourcing/prospeo "Prospeo") - [![](/_astro/rocketreach.rwx2rnfO_Z2gCPob.webp)RocketReach](/tool-directory/sourcing/rocketreach "RocketReach") How it works and where it goes wrongShow less Search or upload a CSV in the vendor's web app, then export. **Where it goes wrong.** Free plans stop early. Lusha Free enriches up to 100 CSV rows at a time, Prospeo Free has no API access, and a RocketReach Free account comes with 3 lookups. 7. 7 ### A verifier API Code Checking a pattern-built address when no finder returns the person. - [![](/_astro/zerobounce.DMK7iQt0_Z4rXLd.webp)ZeroBounce](/tool-directory/verification/zerobounce "ZeroBounce") How it works and where it goes wrongShow less Build the likely address from the company's email pattern (first.last@, f.last@), then keep the one a verifier marks valid. A verifier confirms that the mailbox accepts mail; it does not confirm who owns it. In our 50-person pilot the one wrong-person result came from this route: a pattern-built address that ZeroBounce marked valid belonged to a different person with the same first name. **Where it goes wrong.** An address that passes verification but belongs to someone else. When you have the LinkedIn URL, a finder that matches on it also confirms identity. ZeroBounce also sells an Email Finder, at 20 credits per successful find. 02 ## What it costs at your volume Move the slider to your monthly volume. Each row shows the cheapest published plan or pack that covers it.

Plans renew every month; packs are paid once. Per-action cost: for a pack, its price per credit (unused credits stay for later); for a plan, the month's price divided by your volume, so a plan you do not fill costs more per action. Notes per tool are in the list below. 03 ## Step by step The calls in order, with the endpoint for each step. ### A finder API 1. Copy your Hunter key from the API page in the sidebar (Show or Copy API key). 2. Check credits for free and read requests.credits. `GET /v2/account` 3. Call Email Finder with the domain and first and last name (or a LinkedIn handle). 1 credit if found, free if not. `GET /v2/email-finder` 4. Read the score, sources and verification fields. A 'generated' source\_type means the address was built from the domain's pattern, so verify it. 5. Verify anything you are unsure of for 0.5 credit. Unknown results are free. `GET /v2/email-verifier` ### Verify as you find 1. Call Prospeo's enrich-person with the LinkedIn URL and only\_verified\_email set to true. `POST /enrich-person` 2. For lists, send up to 50 people per request. The same per-record rules apply. `POST /bulk-enrich-person` 3. Treat HTTP 400 with NO\_MATCH as 'no data, no charge' and pass the person to your next provider. 4. Accept the email only when its domain matches the person's live current-employer domain. 5. Right before upload, re-verify every accepted email. ### Waterfall 1. Send up to 100 contacts to FullEnrich (name plus domain, or LinkedIn URL) with enrich\_fields set to contact.work\_emails and a webhook\_url. `POST /contact/enrich/bulk` 2. Wait for the webhook. Polling counts against the 60 calls a minute limit. `GET /contact/enrich/bulk/{enrichment_id}` 3. Read the most\_probable fields. If none came back, nothing passed verification and no credit was used. 4. Filter on status if you want only DELIVERABLE emails, since catch-all results are charged too. ### No-code / Clay 1. In a table, choose Add column, then Add enrichment, and search for Work Email. 2. Map the inputs. The waterfall shows 'Data providers configured 0/11' until you do. 3. Check the per-row cost in Run settings (about 1.1 for the waterfall), then Save. ### Through an AI agent (MCP) 1. Add Prospeo's hosted MCP server to Claude and sign in with OAuth, or send your key in the X-KEY header. `https://mcp.prospeo.io` 2. Ask the agent to run get\_account\_info to check credits. 3. Ask for enrich\_person on a LinkedIn URL, or bulk\_enrich\_person for up to 25 people per call. ### Manual / UI 1. In Lusha, open the CSV enrichment page and upload your list. The Free plan takes up to 100 rows at a time. 2. Reveal emails at 1 credit each and phones at 5. 04 ## What goes wrong, and the fix - A clean-looking email goes to the wrong person. Why A name-only match or a pattern-built address, confirmed only by a verifier. Fix Pass the LinkedIn URL on every lookup and accept provider-verified results only. - Emails land at the person's previous company. Why The provider's employer data is older than the job change. Fix Accept an email only when its domain matches the live current-employer domain. - The waterfall bill is far above the plan. Why The same person sent twice with slightly different inputs, or a higher-cost waterfall step on every row. Fix Dedupe on exact inputs before sending, put cheap providers first, and cap the number of providers per person. - LeadMagic throttles the account mid-run. Why Its fair-use clause covers sustained find rates under 10%, including use late in a waterfall. Fix Call it early in the chain, or keep it for lists it covers well. - A search returns people but no emails. Why Apollo, Prospeo and LeadMagic search endpoints never return emails. Fix Search first, then enrich only the people you keep. Prospeo charges for both steps; Apollo's people search is free on paid plans. - One provider goes down and the whole run stops. Why The pipeline depended on that provider. Fix Make every provider optional and let the person move to the next stage. - A retry charges twice. Why BetterContact submissions are not idempotent. Fix Check GET /account before you resubmit after a timeout. - Old FullEnrich results return an error. Why Results are kept for 3 months only. Fix Store the full result when it arrives. 05 ## Tools that do this job What each tool charges for this job and what to watch for.

[ Book a call ](/book)[ See case studies ](/case-studies) 06 ## Questions people ask How does the email finder work? You send the person's name and company domain, or their LinkedIn URL, and the finder returns its best work address with a status. Hunter, Findymail and LeadMagic take a name plus a domain; Prospeo, Findymail and LeadMagic also take a LinkedIn URL. Some finders check the mailbox at request time (Findymail says it verifies every find in real time). Others return a stored record with a status attached (Apollo marks emails verified or extrapolated). Most charge only when they return an email. What if you can't find the email? First, check the miss was free. Prospeo, Hunter, Findymail, LeadMagic, Forager and FullEnrich charge only for found emails. Then send the miss to a second provider. In our 50-person pilot, one provider found 36 emails, a second lifted the total to 39 (78%), and a third added none. The same 11 people stayed unfindable in every design. If you fill the gap with a pattern-built address, check identity separately: the pilot's one wrong-person result was a pattern-built address that a verifier marked valid. How many providers should a waterfall have? Measure it on your own list. In our 50-person pilot, two providers covered every email we could find (39 of 50), and the third added no unique finds. Changing the order of providers did not change the output. It changed cost only, because each later provider sees only the earlier misses. Hit rates differ by audience, so we pilot 50 rows on every new list before a full run. Why not just use FullEnrich, since it is already a waterfall? You can, and it is the least work: one call across 20+ providers (its docs; the pricing page says 25+) at 1 credit per work email found. Weigh three things. It does not publish which providers it uses or in what order. It charges catch-all results like deliverable ones, so filter on status. And it can repeat providers you already pay for. In one client build we left FullEnrich and BetterContact out of a hand-built waterfall for that reason, and because neither could run on the client's own provider keys inside the routing tool. Do I need Clay to build this? No. Every finder on this page has its own REST API, and most have a hosted MCP server you can use from Claude. Clay helps when your list already lives in a Clay table. In the app on 25 Oct 2026 its Work Email waterfall cost about 1.1 data credits per row across 11 providers, plus Actions. Calling an arbitrary API from Clay needs Growth ($495 a month on monthly billing) or Enterprise. Which tools do waterfall enrichment? Several sell it ready-made: FullEnrich (20+ providers), BetterContact (20+, including RocketReach, Apollo, People Data Labs, Prospeo and Hunter), Clay's Work Email waterfall (11 providers in the app), Apollo's waterfall flag on person enrichment (typically 1 to 4 credits per email, sometimes 20+) and Lusha's Data Waterfall (2 credits per work email from another vendor). You can also build your own by calling single providers in order and stopping at the first verified email. ## Related [How to verify email addresses before you send](/tool-directory/how-to/verify-emails)[Enrichment APIs](/tool-directory/enrichment) Read from each tool's own pricing and API pages, such as [prospeo.io/pricing](https://prospeo.io/pricing), [hunter.io/pricing](https://hunter.io/pricing) and [findymail.com/pricing](https://www.findymail.com/pricing).
