FullEnrich review (2026): a simple waterfall for emails and phones
FullEnrich runs each contact through a waterfall of 20+ data providers and charges only when it finds something. It does one job, emails and mobile numbers, and keeps the waterfall itself out of sight.
pipe0 sells data enrichment and competes with FullEnrich in parts of this review. We say where FullEnrich is better. How we review
Our score for FullEnrich, the average of four criteria
The simplest way to buy emails and mobile numbers from a waterfall: upload a list, pay per result found, done. You can't see or change the providers, and a mobile number costs 10 credits.
Best for
- Sales teams that need emails and mobiles for a list, quickly
- HubSpot users who want enrichment without a new tool
- Anyone who wants waterfall coverage without building one
Skip it if
- You want to see or choose the providers in the waterfall
- You need company data, signals, or enrichment beyond contacts
- Mobile numbers at volume are your main cost
Upload a CSV or connect HubSpot and get emails and phones back. Nothing to configure, unlimited users on every plan.
A waterfall of 20+ providers with email and phone verification. We haven't benchmarked it, and the order of providers is hidden.
From $29 for 500 credits and misses are free, but a mobile number costs 10 credits, about 35 to 58 cents depending on the plan.
A documented async API with webhooks, batches of 100, and an MCP server with OAuth. 60 requests a minute.

What is FullEnrich?
FullEnrich does one thing: you give it people, and it gives you their work emails, personal emails, and mobile numbers. Behind that sits a waterfall of 20+ data providers, Hunter, Wiza, ContactOut, and Snov among them, tried one after another until one finds an answer. Founded in Paris and now based in San Francisco, it raised a $2 million seed round in 2025 and sells mostly to sales teams that want contact data without building anything.
You upload a CSV, connect HubSpot, or call the API. Every email is checked for syntax, mail server, and mailbox before it comes back, and phone numbers are checked for landlines and numbers that no longer work.
Why the waterfall matters
A single database answers from one dataset, and where it is thin you get nothing. A waterfall asks the next provider instead, so coverage grows with every source behind it. FullEnrich sells exactly that coverage, packaged so you never see the providers.
That packaging is the trade-off. You can't tell which provider answered, and you can't change the order. When a result is wrong, or a provider is slow or expensive, there is nothing to adjust. We haven't benchmarked FullEnrich, so we can't say how its hidden order compares with an open one.
What it costs
Pro plans start at $29 a month for 500 credits and drop to 3.5 cents a credit at 100,000. A work email costs 1 credit, a personal email 3, and a mobile number 10. Results that aren't found cost nothing, landlines are free, and re-enriching the same contact within three months is free too. Unused credits roll over for three months on monthly plans.
The mobile price is where it adds up. At 10 credits each, a mobile number costs about 58 cents on the smallest plan and 35 cents at the largest.
FullEnrich for developers and agents
The API takes batches of up to 100 contacts and sends results back by signed
webhook, typically within 30 to 90 seconds per contact, at 60 requests a
minute. The MCP server at mcp.fullenrich.com signs in with OAuth, and
there is a CLI. All of it is included from the free trial up.
FullEnrich vs pipe0
pipe0 runs waterfalls too, and also bills only for results found. The differences are what you can see and what else you get. A pipe0 waterfall is curated and visible: you can see which provider answered and reorder them. It sits next to company data, 100+ enrichments, and sheets that run on schedules, and we measure it as about 7x as cost effective as waterfall providers. Test that on your own list; the full comparison has the details.
Who should buy FullEnrich
Buy FullEnrich if you need emails and mobile numbers for a list, you want waterfall coverage without building one, and you don't need to know where each answer came from.
Look elsewhere if you want to control the waterfall, if mobile numbers at volume are your biggest cost, or if your needs go beyond contact details.
FullEnrich pros and cons
Pros
Waterfall coverage, no setup
Each contact goes through 20+ providers, including Hunter, Wiza, ContactOut, and Snov, until one answers. You don't manage any of them.
Only pay for what it finds
Not-found results and landlines cost nothing, and re-enriching the same contact within three months is free.
Verification built in
Emails pass syntax, MX, and SMTP checks, including catch-all verification, and phones are checked for landlines and dead numbers.
Agent-ready
An async API with signed webhooks, an MCP server for Claude and other clients, and a CLI, all included from the free trial up.
Cons
A closed waterfall
You can't see which provider answered or reorder them. When a result is wrong, there is nothing to tune.
Mobile numbers are expensive
A mobile costs 10 credits and a personal email 3. On the smallest plan that is about 58 cents per mobile found.
Contacts only
Emails, phones, and basic profiles. No company signals, custom enrichment, or scheduled syncs beyond HubSpot.
No browser extension
FullEnrich retired its Chrome extension, so enrichment from LinkedIn runs through lists or integrations.
