Clay is where you build GTM workflows: tables, web research, signals, CRM sync and email sequences. FullEnrich is a contact enrichment tool that finds and verifies work emails and mobiles from 25+ sources in one step. FullEnrich runs inside Clay as a native integration built by Clay, or on its own through its app, API and MCP. Clay facts come from Clay’s own pages, checked on 9 October 2026.

Three reasons your own waterfall misses at volume, and what each one costs you.
Running your own waterfall
Providers throttle big tables, so rows wait, time out or never run.
Some providers on your own keys charge for the miss, so an empty cell can still cost you.
Your waterfall runs every contact through the same fixed order, but each provider is strong in some countries and industries and weak in others, so many rows reach a good match late.
With FullEnrich, running the waterfall is our job.
Running FullEnrich
Clay rows run in parallel, so a 10,000-row table keeps going.
1 credit per verified email, 10 per verified mobile, nothing on a miss.
FullEnrich reorders its 25+ providers for each contact, based on country and industry, so the providers most likely to find that person run first.
FullEnrich sets its own order and you cannot reorder it. Keep yours, then test it on 10 rows your table missed and 10 it filled.
In Clay, you choose the providers, their order, the validation provider and the strategy. Clay’s Work Email waterfall then stops at the first valid result. FullEnrich orders its 25+ sources for each contact’s country and industry, checks every email with 3 verification methods and labels it Valid, Probably valid or Catch-all in the FullEnrich app and API.
Clay gives you the controls: you reorder, add or delete providers, choose the validation provider and decide how much risk counts as valid.
Six ways contact data goes wrong without anyone noticing, and how each one plays out in a waterfall you configure and in FullEnrich.
A catch-all ends the search before a valid email turns up.
In a waterfall you configure
If your strategy counts catch-alls as valid, the first catch-all stops the waterfall. A later source with a verifiable address never runs.
In FullEnrich
Every catch-all gets extra checks for signs the address is in use, then a label: Probably valid or Catch-all. You see which one you have before you send.
Clay docs, Work Email waterfall · FullEnrich help, How we verify emails
A catch-all server makes a basic mailbox check say valid.
In a waterfall you configure
A waterfall that validates with one provider inherits that provider’s blind spots. Catch-all servers are the usual one.
In FullEnrich
FullEnrich combines several verifiers. In its own benchmark of verification services, emails one verifier marked valid still bounced about 10% of the time, mostly undetected catch-alls.
FullEnrich help, How we verify emails (vendor-reported)
An office line fills the mobile cell.
In a waterfall you configure
If the first phone source returns a landline and the waterfall stops on any value, the source that holds the mobile never runs. The row looks found.
In FullEnrich
FullEnrich checks each line type with the carrier. Landlines, VoIP and disconnected numbers are dropped at 0 credits, and the search goes on to a mobile.
FullEnrich changelog, 15 Sep 2026 · FullEnrich help, How we verify phone numbers
The number is live, but it belongs to someone else.
In a waterfall you configure
A line-type check passes a namesake’s mobile or a recycled number that changed owner. Your rep calls a stranger.
In FullEnrich
On US and Canada numbers, FullEnrich checks the line owner against your lead and shows how sure the match is. Numbers from the wrong country are rejected too.
FullEnrich changelog, 15 Sep 2026
A valid email belongs to someone who left.
In a waterfall you configure
Any mailbox check, FullEnrich’s included, confirms the address exists. It does not confirm your lead still reads it.
In FullEnrich
FullEnrich’s bounced-email template runs in your Clay table. It finds where the contact works now and returns their new verified work email.
Clay helps here: its job change signals flag the move.

A row without a LinkedIn URL gets fewer sources.
In a waterfall you configure
Clay’s docs say a profile URL increases accuracy. Rows that arrive with only a name and a company skip the sources that need one.
In FullEnrich
In the FullEnrich app and API, FullEnrich finds the LinkedIn profile from first name, last name and company first, so more of its sources can run.

Inside Clay, the FullEnrich actions bill on one of two routes. On your own FullEnrich account, Clay charges no Data Credits for that step and still counts an Action when it returns a result. On Clay credits, Clay shows the cost next to the action. FullEnrich charges 1 credit per work email, 10 per mobile and 0 on a miss.
| Contact step | In Clay, on Clay credits | In Clay, on your FullEnrich account | FullEnrich on its own |
|---|---|---|---|

1,000 contacts cost at most 11,000 FullEnrich credits, in Clay or outside it. That is 1 credit per checked email and 10 per mobile if every row is found. Emails only, it is at most 1,000. Every miss costs 0.
To compare the two Clay routes, add up the Data Credits Clay shows next to each provider and validation step. Multiply that by your Data Credit price. Then set it against your FullEnrich price per credit.
Clay figures from Clay’s pricing page and docs, 9 October 2026. FullEnrich figures from fullenrich.com/pricing.
Mixing providers buys coverage, and each provider bills you its own way.
Every key has its own billing rule.
Some providers charge per lookup, so a row they miss still costs you. Others charge only for a match.
Refunds depend on the provider.
Some refund an invalid email and some do not, so bad data can stay on your bill.
Your validator is one more provider contract.
If you set one, Clay adds a validation column after each provider step, and your validator bills every check.
Re-running a column bills rows you already filled.
Each provider bills the row again. Clay’s own tip is to run a column only when the field is empty.
One FullEnrich account covers 25+ sources on one bill, with 3 verification methods on every email inside its 1 credit.
Price per credit drops from $0.058 at 500 credits a month to $0.035 at 100,000. Enterprise sets a custom rate above that.
| Credits a month | Price per credit |
|---|---|
| 500 | $0.058 |

FullEnrich powers 11x’s new version. Our coverage went from 200 million to 1.6 billion contacts, letting us win deals where competitors had zero coverage. It's the simplest solution by far and more economical than building in-house.
FullEnrich is a native integration in Clay’s marketplace, built by Clay, with two actions: Find work email and Find mobile phone. Clay connects the table to CRMs, sequencers, warehouses and HTTP APIs, so FullEnrich results travel wherever Clay sends them. Outside Clay, the same FullEnrich account connects to HubSpot, Zapier, Make, n8n, its API and MCP. Clay facts come from Clay’s own pages, checked on 9 October 2026.

Clay and FullEnrich each publish their own certifications. Clay lists SOC 2 Type 2, ISO 27001:2022 and ISO 42001:2023. FullEnrich holds SOC 2 Type II, and ISO 27001 sits with its EU host. For the contacts you enrich, inside Clay or on its own, FullEnrich acts as a processor under its published data processing agreement.
Between the two tools, Clay sends a row’s name with its company, domain or profile URL. FullEnrich returns the work email or mobile it finds. On your own FullEnrich account, you sign FullEnrich’s DPA as its customer.
FullEnrich runs in Clay as two actions: Find work email and Find mobile phone. Clay’s “Only run if” condition decides which rows each one touches. Pick the setup that matches your table, then run it on 20 rows before you scale: 10 your table missed and 10 it filled.
Your waterfall works, but some rows stay empty.
Keep your providers and their order. FullEnrich only sees the rows your last provider left blank.
Test it on the rows your waterfall missed, plus a few it filled to check they agree.
Your reps dial, and mobile credits go fast.
Spend mobile credits on the rows a rep will dial, filtered by title, owner or score.
Test it on 20 rows your reps will call this month, then check who picks up.
You would rather not maintain an email waterfall.
One step searches 25+ sources and checks each email inside it. The trade: you cannot change the order FullEnrich sets.
Test it beside your current email column on the same 20 rows.
50 free credits, no card: a 20-row email test, or 5 verified mobiles.

“When you're scaling a 1,000-person sales org across 80 countries, bad data kills your pipeline. We piloted FullEnrich with over 70 reps. The results? 2.4x more mobiles found, connect rates that jumped from 6% to 30%, and 5x fewer invalid numbers. They're not just another data vendor. They're the foundation our global outreach runs on.”

“Your real differentiator is the accuracy of the data. You've developed a technique where you know what's accurate and what's not, which is not the same as other players. When you're scaling as we are, even a 5 to 10% accuracy increase has a huge impact on the entire yield.”
