FullEnrich vs Snov.io (2026): Data, Pricing and API Compared

FullEnrich is a waterfall enrichment tool. It asks 25+ data sources for each email and phone and bills credits for what it finds. Snov.io is an outreach suite that sells emails by the credit, with an API and MCP server attached. They overlap on email finding and little else.

Verdict

• Pick FullEnrich if you need mobile numbers and work emails on a list you already hold, and you want to pay only for what it finds. It has the API and MCP on every plan.
• Pick Snov.io if you want emails for a few thousand prospects a month and want to send the campaign from the same app. Its entry price is low and its plans include a CRM.
• Pick neither if you want to search one database by title, seniority and country, with phones, at a fixed price. LeadOcean is one option: Pro is $499 a month, flat.

Side by side

Data and coverage

FullEnrich is built to find contact details for people you already know. Snov.io is built to find prospects and email them. The record counts are not like for like.

FullEnrich's pricing page lists 800M people and 50M companies for search. Its homepage also carries a customer quote about 1.6B contacts, which describes coverage for one customer, not the database size (FullEnrich pricing, September 2026). FullEnrich says its verification removes about 30% of raw data and that work emails are found about 80% of the time (FullEnrich pricing, September 2026). Those are its numbers, not ours.

Snov.io gives two sizes. The lead finder page claims 500M+ verified contacts and 60M+ companies. The Database Search guide says 50M+ prospects, refreshed monthly (Snov.io lead finder; Snov.io help, September 2026). We cannot tell you which one the search queries.

Phones are where they split. FullEnrich runs a waterfall, so a miss at one source is tried at the next. Snov.io does not. You pick one provider per search, Wiza at 10 tokens or Zeliq at 22, and if it finds nothing you try the other (Snov.io help, September 2026). Snov.io says the dearer provider has wider coverage. Neither vendor publishes a phone count.

Test both on your own list. Each has a free allowance of 50 credits, and a 200-row sample shows the real find rate.

API and developer experience

Both APIs are REST, both take a Bearer token, and both are asynchronous for the useful calls. The difference is where the token comes from.

FullEnrich uses an API key as the Bearer value. You start a bulk enrichment of up to 100 contacts, name it, and pick the fields. The docs recommend a webhook for results and list a poll endpoint, GET /bulk/enrichment_id, as the second choice (FullEnrich docs, September 2026).

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

Snov.io makes you exchange a client ID and secret for a token that lasts 3,600 seconds. Then you start a task, here a name plus domain with up to 10 rows, and collect the result with a task hash (Snov.io API docs, September 2026).

TOKEN=$(curl -s -X POST "https://api.snov.io/v1/oauth/access_token" \
  -d grant_type=client_credentials \
  -d client_id="$SNOV_CLIENT_ID" -d client_secret="$SNOV_CLIENT_SECRET" | jq -r .access_token)

curl -X POST "https://api.snov.io/v2/emails-by-domain-by-name/start" \
  -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -d '{"rows":[{"first_name":"Jane","last_name":"Doe","domain":"acme.com"}]}'

Rate limits shape scale. Both allow 60 calls a minute. FullEnrich takes 100 contacts a call, so up to 6,000 contacts a minute. Snov.io takes 10 name rows a call, so up to 600 a minute on that endpoint. Over the limit, FullEnrich returns HTTP 429 until the next calendar minute (FullEnrich docs, September 2026).

On MCP, both have official remote servers with OAuth sign-in. FullEnrich's is at https://mcp.fullenrich.com/mcp and previews 10 search results free. Snov.io's is at https://mcp.snov.io/mcp and works on its Sales Suite and LinkedIn plans (Snov.io help, September 2026).

Pricing

FullEnrich charges per field found: 1 credit for a work email, 3 for a personal email, 10 for a mobile. Snov.io charges 1 credit per valid or unknown email and separate tokens for phones. Arithmetic below uses monthly list prices first, then billed-yearly prices.

At 10,000 records a month

Work emails. FullEnrich needs 10,000 credits. The 10,000-credit tier is $499 a month ($0.050 a credit), or $454 a month billed yearly for 120,000 credits a year. At the 80% find rate FullEnrich states, you would spend about 8,000 credits. The 5,000-credit tier ($255) is still too small, so you buy the 10,000 tier (FullEnrich pricing, September 2026).

Snov.io needs 10,000 credits. Pro S has 5,000, so you buy Pro M: 20,000 credits for $189 a month, or $141.75 billed yearly. If you use 10,000 of them, that is $189 / 10,000 = $0.0189 an email (Snov.io pricing, September 2026).

For emails alone, Snov.io is about 2.6 times cheaper at this size: $499 / $189.

Mobiles. FullEnrich charges 10 credits per mobile found. 10,000 mobiles is 100,000 credits, which is the top public tier at $3,500 a month, or $0.35 a mobile. Billed yearly, the 1,200,000-credit tier is $37,800, or $3,150 a month (FullEnrich pricing, September 2026).

Snov.io tokens cost $0.02 each in packages valid for 90 days (Snov.io pricing, September 2026). 10,000 numbers through Wiza is 10,000 x 10 x $0.02 = $2,000. Through Zeliq it is 10,000 x 22 x $0.02 = $4,400.

Snov.io is cheaper per number through Wiza. Whether it finds as many numbers as a 25-source waterfall is a question for your own test.

At 1M records

Neither vendor publishes a price at 1M, so we do not multiply a small-plan rate out to a million.

FullEnrich's top monthly tier is 100,000 credits for $3,500. Above it the page says contact sales. The yearly toggle stops at 1,200,000 credits a year for $37,800 (FullEnrich pricing, September 2026). FullEnrich does not say whether yearly credits arrive upfront or monthly. A million work-email lookups needs 1M credits.

Snov.io's top public plan is Ultra at $738 a month for 100,000 credits, or $553.50 billed yearly. Beyond it is Custom Ultra, from 200,000 credits, by quote (Snov.io pricing, September 2026). Phones stay on tokens.

Ask both for a quote at your volume. Neither number is on a page you can read.

Where FullEnrich wins

• Phone waterfall. A miss at one of its 25+ sources is tried at the next. Snov.io searches one provider at a time.
• Pay on found only. A miss or a landline costs 0 credits.
• API on every plan. The API, MCP and bulk CSV are included from the free trial up, with unlimited users (FullEnrich pricing, September 2026).
• Bulk throughput. 100 contacts a call against 10 name rows on Snov.io.
• Search stays cheap. The MCP search previews 10 results and the total count at no cost.

Where Snov.io wins

• Price at small volume. Starter is $39 a month, and a Pro M credit is about 0.9 cents by Snov.io's own figure (Snov.io pricing, September 2026).
• Sending in the same app. Campaigns, warm-up, a CRM and LinkedIn automation come with the plan. FullEnrich has none of these.
• No sales call at 100,000 credits. Ultra at $738 is a public price for 100,000 credits.
• Prospecting extensions. The Email Finder and LinkedIn Prospect Finder Chrome extensions are on every plan (Snov.io pricing, September 2026).

If you need volume through an API

We build LeadOcean, so weigh this section accordingly. LeadOcean holds 693M people and 63M companies, with 166M people carrying a phone number, reachable over REST and MCP. Free is 1,000 records, one-off, with no card. Pro is $499 a month, flat, with no credits and 100 requests per second per key (LeadOcean pricing, September 2026).

For bulk work, POST /v1/exports returns up to 50,000 rows per request. The app has an Exports page with a filter builder, a price preview and CSV download (LeadOcean exports docs, September 2026). There is no sequencer, dialer or CRM. Read the FullEnrich alternative page or the Snov.io alternative page for line-by-line versions.
