Findymail vs FullEnrich (2026): Data, Pricing and API Compared

Findymail and FullEnrich both find work emails and phone numbers and charge credits for what they find. Findymail verifies each email live and stays narrow. FullEnrich asks 25+ sources and publishes more of its price list.

Facts below were checked in September 2026, each with its source link. Where a vendor shows nothing we could read, the page says so.

Verdict

• Pick Findymail if you want a verified email from a name and domain, plus lead lists and signals, and you accept that its plan prices sit behind a bot check.
• Pick FullEnrich if you want a waterfall across 25+ sources, mobile numbers with no stated US-only limit, and a price ladder you can read up to 100,000 credits a month.
• Pick neither if you start from an audience, not a name list. You need filters and a fixed bill at 1M records. See the LeadOcean section below.

Side by side

Prices are USD list prices, monthly first, billed yearly after it.

Data and coverage

Neither tool sells a database you browse for contacts. Coverage is a find rate on your list. Neither publishes a find rate we could verify, apart from FullEnrich's own claim.

Findymail returns a verified email or nothing. It charges a finder credit only when a verified email is found (Findymail API docs, September 2026). It also covers:

• Phones: 10 credits per number, US only, nothing for EU citizens.
• Lead lists: Intellimatch takes a plain-language query and returns up to 5,000 companies per search.
• Employees: one call returns a few contacts at a company, 1 credit each, as LinkedIn profiles.
• Verifier: a separate check at 1 verifier credit, for emails you already hold.

FullEnrich runs a waterfall. Its pricing page lists 25+ data sources and access to 800M people and 50M companies for search (FullEnrich pricing, September 2026). The 1.6B figure on its homepage is a customer quote, not a database size.

FullEnrich states about an 80% find rate on work emails, and says about 30% of raw data is removed by verification (FullEnrich pricing.md, September 2026). Both are its own claims and we have not tested them.

A not-found result costs nothing on either side. On FullEnrich a landline also costs 0 credits (FullEnrich docs, September 2026).

For a list of names and domains, run 500 rows through both and compare found counts. That beats any published rate.

Check the list shape too. Findymail can start from a name and a domain, or from a business profile URL. FullEnrich takes a name plus a domain or company name, or a LinkedIn URL. It says a LinkedIn URL lifts email rates by 5 to 20% and mobile rates by 10 to 60% (FullEnrich docs, September 2026). If your list has profile URLs, both tools do better.

API and developer experience

Both are REST APIs with Bearer tokens and webhook support. Findymail answers one lookup per call. FullEnrich takes up to 100 contacts per call and returns results by webhook.

Findymail, from its API docs, checked September 2026.

curl --request POST "https://app.findymail.com/api/search/name" \
  --header "Authorization: Bearer $FINDYMAIL_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{"name": "Jane Doe", "domain": "acme.com"}'

FullEnrich, from its bulk enrichment docs, checked September 2026.

curl --request POST "https://app.fullenrich.com/api/v2/contact/enrich/bulk" \
  --header "Authorization: Bearer $FULLENRICH_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
    "name": "Acme prospects",
    "webhook_url": "https://example.com/webhook",
    "data": [{
      "first_name": "Jane",
      "last_name": "Doe",
      "domain": "acme.com",
      "enrich_fields": ["contact.work_emails"]
    }]
  }'

Findymail returns the contact in the response, or posts it to a webhook_url you set. FullEnrich is built around the webhook: you start a job, and results arrive later. It documents a polling endpoint but does not recommend it.

The practical difference is the loop you write. With Findymail you send one request per person and handle a 402 when credits run out. With FullEnrich you batch 100 people, store the job name, and wait for the callback. Pass a custom object, such as your CRM id, and it comes back on the webhook so you can match results to rows (FullEnrich docs, September 2026).

On MCP, Findymail exposes 14 tools, including phone, employees, lead lists and exclusion lists. FullEnrich covers search, enrich and export in the assistant, and the help center does not give a tool count.

Limits differ in kind. Findymail caps concurrency at 300 simultaneous requests (Findymail API docs, September 2026). FullEnrich caps rate at 60 calls a minute, which at 100 contacts a call is 6,000 contacts a minute. Over the limit you get HTTP 429 with the code error.rate.limit (FullEnrich docs, September 2026).

Pricing

Both bill per found contact, so the bill follows your hit rate. Findymail's plan prices sit behind a bot check, so only FullEnrich can be priced here.

At 10,000 work emails a month

• FullEnrich: 10,000 credits at 1 credit each. The 10,000-credit monthly tier is $499 ($0.050 a credit). Billed yearly, 120,000 credits a year cost $5,448, which is $454 a month (FullEnrich pricing.md, September 2026).
• Findymail: 10,000 finder credits if every lookup finds a verified email. We could not read plan prices, so read the step that covers 10,000 on Findymail's pricing page.

Misses are free on both, so a lower hit rate uses fewer credits. Phones change the sum. 10,000 mobiles on FullEnrich is 100,000 credits, the $3,500 tier. On Findymail the same list is 100,000 finder credits, for US numbers only.

At 1M work emails a month

• FullEnrich: 1,000,000 credits. No public 1M price. The top monthly tier is 100,000 credits for $3,500 a month ($0.035 a credit), a tenth of the volume. Above it the page says contact sales. The yearly toggle stops at 1,200,000 credits a year for $37,800 (FullEnrich pricing.md, September 2026).
• Findymail: 1,000,000 finder credits. No public 1M price. Ask for a quote.

If you want a figure to plan with, the arithmetic at FullEnrich's top monthly rate is 1,000,000 x $0.035 = $35,000. That is arithmetic, not a price, and FullEnrich does not say it sells that volume at that rate. FullEnrich does not say whether annual credits arrive upfront or monthly, so the yearly tier is not a confirmed path to 1M in one month.

Free entry: FullEnrich gives 50 trial credits with no card (FullEnrich pricing, September 2026). Findymail's API page says sign-up is free with no card, but we could not read its free-credit terms (Findymail API page, September 2026). Unused FullEnrich credits roll over 3 months on monthly plans and 12 on annual plans.

Where Findymail wins

• Live verification. Every email is checked when you ask, and you pay only for a verified one.
• Lead lists. Intellimatch builds companies and contacts from a sentence. FullEnrich needs your list or a search.
• Wider toolset in an agent. 14 MCP tools, including a standalone verifier and exclusion lists.
• Standalone verifier. A separate check for emails you already hold, at 1 verifier credit.

Where FullEnrich wins

• Readable prices. The ladder from 500 to 100,000 credits is on one page, with a yearly view.
• Waterfall. 25+ sources per lookup, so a miss at one source can still hit at the next.
• Bulk by design. 100 contacts per request and a webhook for results. API and bulk CSV are on every plan, trial included.
• Free tier terms. 50 credits, no card, unlimited users, API and MCP included.

If you need volume through an API

Neither tool is built to pull a million records from a filterable database. LeadOcean is a people and company database with 693M people and 63M companies. It is not a drop-in swap for name-and-domain lookups: you search by domain first, then enrich by person_id. Pro costs $499 a month, flat, with no credits and no per-record price, and Free gives 1,000 records one-off with no card. Both plans get the same REST API and 12-tool MCP server, and POST /v1/exports returns up to 50,000 rows per request (LeadOcean exports docs, September 2026). See LeadOcean pricing.
