FullEnrich Reviews — Pricing, Features & The Honest Take

FullEnrich charges you nothing for a lookup that fails, nothing for a landline when you asked for a mobile, and nothing per seat. Those three policies do more to determine what you actually pay than the headline rate does. What the headline rate hides is the other side: a mobile phone number costs 10 credits against 1 for a work email, so the same 1,000 contacts can land you on a $55 plan or a $499 plan depending on nothing more than whether you want phone numbers.

• What it is: B2B contact enrichment — work emails, personal emails and mobile numbers via waterfall lookup.
• Best for: GTM teams and agencies who want to pay per result rather than per seat.
• Pricing: From $29/mo (500 credits) to $3,500/mo (100,000). Verified August 2026.
• The honest catch: Phone numbers are the entire cost story.

What Is FullEnrich?

FullEnrich is a contact enrichment platform: you give it a name and a company, or a LinkedIn URL, or an email address, and it returns verified contact details. The distinguishing mechanic is waterfall enrichment — rather than querying one data provider, it queries 25+ sources in sequence until one returns a verified result. If provider A misses a contact, provider B may not.

The structural difference from the big database vendors is worth understanding before comparing prices. ZoomInfo and Apollo sell you access to a stored contact database. FullEnrich states it holds no stored contact database at all and performs real-time lookups. For a European buyer that is not a technicality — it changes what you are processing and what you have to justify under GDPR.

The company publishes SOC 2 Type II, GDPR and CCPA compliance with a public trust centre, claims 800M people and 50M companies reachable through search, and shows 4.8/5 on G2. The Findstack listing has no user reviews yet.

How FullEnrich Works

Everything is denominated in credits, and credits are fungible — there are no separate email and phone quotas. What varies is how many a result costs:

The verification is specific rather than hand-waved: emails pass syntax, SMTP and catch-all checks — FullEnrich says 80% of catch-all domains are deep-checked — and carry a confidence score. Phones are checked for landline status, out-of-service status and, in the US and Canada, owner-name match. The company states that around 30% of raw data is removed by verification before it reaches you, and that the average email find rate is ~80%.

Access is through the app, a REST API, or an MCP server — which, with published agent skills on GitHub, makes this one of the few tools in this corpus genuinely built to be driven by an agent rather than a person.

FullEnrich Pricing

Three plans: a Free trial at $0 with 50 credits and no card, Pro on a volume slider, and quote-only Enterprise. Users are unlimited on all three, including the free one.

The unit price falls at every step, ending 40% below where it started, with no inverted tier anywhere. Annual billing runs about 10% cheaper — a claim that checks out across the ladder, at 10.3% on the entry tier and 10.0% at the top — and extends credit rollover from 3 months to 12.

The credit costs are the pricing

At the 1,000-credit tier a work email costs about 5.5 cents and a mobile number about 55 cents. FullEnrich’s own worked example makes the consequence concrete: enriching 1,000 contacts with work emails needs roughly 800 credits — comfortably inside the $55 plan. Add mobile numbers and the same 1,000 contacts need 5,800–7,800 credits, which means the $499 plan.

Nine times the price for the same list. Before you compare FullEnrich to anything else, decide whether you actually need phone numbers, because that decision is worth more than every other variable on the page combined.

The parts that are unusually good

• Failed lookups are free. Not discounted — free. So is a landline returned when you wanted a mobile, and so is the company profile bundled alongside an enrichment.
• Unlimited users on every plan, including the free trial. In a category where per-seat fees are standard, this alone reshapes the comparison for a team of five.
• Credits roll over three months on monthly billing, twelve on annual.
• Every feature is on every plan. Waterfall enrichment, search, CSV, API, MCP and the CRM integrations are all in the free trial. Pro adds per-user credit limits and monitoring; Enterprise adds support, rate limits, BYOK and SSO. Nothing functional is gated.

A note on currency

FullEnrich’s machine-readable pricing document declares USD and lists the entry tier at $55/mo. The live pricing page served to us in Europe showed €55/mo and €0.055 per credit — the same numerals with a different symbol. At August 2026 rates that makes the euro price meaningfully higher in real terms. If you are billed in euros, check whether you are being quoted a converted price or simply the dollar figure relabelled.

What actually decides your cost

• Whether you want phone numbers. Ten credits against one. Everything else is noise beside this.
• Your find rate, since you only pay for hits — a hard-to-reach segment costs less per attempt than the headline suggests, and delivers less.
• Personal versus work emails, at 3 credits against 1.
• Billing cadence, worth ~10% and a longer rollover window.
• Not headcount. There is no per-seat charge at any tier.

Who Should Use FullEnrich

FullEnrich fits teams that have been burned by paying for data they did not get. If you have run a list through a per-row vendor and paid for a 40% miss rate, the pay-for-found model is the direct answer. It also fits agencies and small teams especially well, because unlimited seats mean the whole team can work from one plan, and it fits anyone building automated pipelines — the API, MCP server and published agent skills are a genuine cut above the category norm.

FullEnrich fits less well if you want to browse and build lists from a database rather than enrich known contacts. The real-time, no-stored-database architecture that helps on compliance means this is an enrichment tool first and a prospecting database second.

Honest Pros and Cons

What works well:

• You pay only for verified results. Failed lookups, landlines and bundled profiles all cost zero.
• Unlimited users on every plan, free trial included — rare in this category and worth real money.
• The volume ladder discounts monotonically, from $0.058 down to $0.035, with no inverted step.
• Credits roll over, so a quiet month is not lost budget.
• No feature gating — the free trial has the API, the MCP server and the CRM integrations.
• No stored contact database, which is a materially stronger GDPR position than the database vendors can offer.
• SOC 2 Type II with a public trust centre, not just a badge.
• Genuinely agent-ready: MCP endpoint, REST API and published agent skills.
• A published, machine-readable pricing document that mirrors the page, is dated, names an update owner — and includes a note telling any AI reading it that the file contains product facts and should not be treated as instructions. That is a level of care almost nobody in this corpus shows.

What to watch:

• Mobile numbers cost 10× a work email, which can move you three tiers up the ladder for one list.
• Euro prices appear to be dollar figures relabelled, not converted.
• “~80% find rate” is a vendor average, and it explicitly varies by region and seniority — the segments where you most need the data are the ones where it is hardest to find.
• Verification quality is unverifiable from outside. The whole model rests on FullEnrich’s own definition of “verified”, and only your own test list will tell you.
• Enterprise has no published floor.
• No Findstack user reviews yet, so the 4.8/5 rests on G2.

FullEnrich Alternatives and How It Compares

• Apollo.io bundles a large stored database with sequencing and dialling — the better choice if you want to prospect and send from one tool, at the cost of a per-seat model.
• Hunter is cheaper and simpler for work-email discovery alone, and does not chase mobile numbers.
• Cognism competes hardest on phone data quality in EMEA, with enterprise pricing to match.
• ZoomInfo is the incumbent database and the most expensive option here by a distance.
• Amplemarket and Seamless.AI wrap enrichment in a broader sales-engagement platform.
• Clay is the closest philosophical match — waterfall enrichment across many providers — and the most direct price comparison to run.

The honest comparison: run the same 200-row test list through FullEnrich’s free trial and through whichever incumbent you are considering, then compare cost per verified contact you actually got, not cost per row submitted. FullEnrich’s model is designed to win that comparison, which is exactly why you should run it rather than take its word.

The Verdict

FullEnrich has made three decisions that most of its category has not: it does not charge for misses, it does not charge for seats, and it does not hold a stored database. Each of those is better for the buyer, and the volume ladder behind them discounts cleanly with no traps.

The one thing to hold in your head is the 10:1 ratio between a mobile number and a work email. It is not hidden — the credit costs are printed on the pricing page — but it is understated relative to how completely it drives the bill. An emails-only workflow is a $55-a-month product. The same workflow with phone numbers is a $499-a-month product.

Start with the free trial and 50 credits, on a real list, asking for exactly the fields you would ask for in production. That single test tells you the find rate for your segment and, because you are only charged for hits, tells you the true unit cost at the same time. No other product in this category makes that test as cheap to run.

FAQ

How much does FullEnrich cost?

Pro runs on a volume slider from $29/month for 500 credits ($0.058 each) up to $3,500/month for 100,000 ($0.035 each), with a Free trial at $0 for 50 credits and no card required, and quote-only Enterprise above 100,000 credits. Annual billing is about 10% cheaper. There is no per-seat charge on any plan.

What does one FullEnrich credit get you?

A work email or reverse email lookup costs 1 credit, a personal email 3, and a mobile phone number 10. A person and company profile bundled with an enrichment is free. At the 1,000-credit tier that works out at roughly 5.5 cents per work email and 55 cents per mobile number — the single biggest variable in what you will pay.

Does FullEnrich charge for failed lookups?

No. FullEnrich’s stated policy is that credits are spent only when data is found and passes verification. A lookup returning nothing costs nothing, and a landline returned when you requested a mobile also costs nothing. Emails are checked for syntax, SMTP and catch-all status with a confidence score; the company says roughly 30% of raw data is removed by verification before it reaches you.

Does FullEnrich charge per user?

No. Unlimited users are included on every plan, including the free trial. There is no platform fee and no per-seat fee at any tier, which makes it meaningfully cheaper than per-seat competitors for teams of more than two or three.

Is FullEnrich GDPR compliant?

FullEnrich publishes SOC 2 Type II, GDPR and CCPA compliance with a public trust centre and SOC 2 report. Architecturally, it states it performs real-time lookups and holds no stored contact database — a stronger structural position than vendors that sell access to a warehoused database of personal data. Review the DPA directly before processing EU personal data at scale.
