FullEnrich and Clay both run waterfall enrichment across many data providers and both skip the charge when nothing is found. The difference is scope. FullEnrich is a finished product for emails and mobiles, at a fixed 10 credits per mobile and from $29 a month. Clay is a workflow platform with 150+ providers, from $185 a month, where the cost of a phone lookup depends on the provider you pick. Every number below was read on September 28, 2026.
Disclosure first: we are Overloop, and we sell contact data and outreach, so we compete with both FullEnrich and Clay. Every price and figure below was read on the vendors' official pages on September 28, 2026. Where one of them is the better choice for your team, we say so.
FullEnrich vs Clay: the short answer
Choose FullEnrich if the job is emails and mobile numbers on a list, and you want a price you can compute before you start: 10 credits per mobile found, about $0.35 to $0.58 per mobile depending on volume, unlimited users, nothing to build.
Choose Clay if the job is bigger than contact data: research accounts with AI, track job changes and signals, sync the CRM, and route rows into sequences. You design the waterfall and pick the providers; Clay does not publish one price for a phone number.
Choose Overloop if the number has to go straight into outreach. Overloop, our product, reveals a phone number for 5 credits, charged only when one is found, and runs the email and LinkedIn sequence from the same prospect record. Plans start at $69 per user per month with 250 credits.

Pricing
FullEnrich (FullEnrich machine-readable pricing, September 28, 2026): monthly Pro tiers of 500 credits for $29, 1,000 for $55, 10,000 for $499 and 100,000 for $3,500; annual from $26 a month for 6,000 credits a year. Mobile 10 credits, work email 1, personal email 3. No per-seat fee.
Clay (Clay pricing, September 28, 2026) splits its price into two meters. Actions pay for the platform work; data credits pay for data bought from its marketplace. Free includes 500 actions and 100 data credits a month but no phone enrichment. Launch starts at $185 a month on monthly billing ($60 for 15,000 actions plus $125 for 2,500 data credits), or $167 a month on annual billing. Growth starts at $495 a month monthly, or $446 on annual billing, and adds CRM auto-sync, HTTP API and webhooks. Enterprise is custom. Bringing your own provider API keys skips data credits; actions still apply.
Cost per mobile number
| Tool | Plan | How we computed it | Price per phone number |
|---|---|---|---|
| FullEnrich | Pro, 500 credits a month | $29, 10 credits per mobile = 50 mobiles | about $0.58 |
| FullEnrich | Pro, 1,000 credits a month | $55 = 100 mobiles | $0.55 |
| FullEnrich | Pro, 10,000 credits a month | $499 = 1,000 mobiles | about $0.50 |
| FullEnrich | Pro, 12,000 credits a year | $588 a year ($49 a month) = 1,200 mobiles | $0.49 |
| FullEnrich | Pro, 100,000 credits a month | $3,500 = 10,000 mobiles | $0.35 |
| Clay | Launch, monthly | $185 = $60 platform actions + $125 for 2,500 data credits ($0.05 a data credit); the data credits a phone lookup costs depend on the provider and are shown in the app | Not published as one figure |
| Overloop | Starter or Growth | Phone reveal draws on the plan's shared credits | 5 credits, only on a match (see pricing) |
Clay's credits guide says a fully enriched record typically costs 6 to 20 data credits and that phone numbers are the expensive part (Clay credits guide). At $0.05 a data credit, every 10 data credits a provider charges is $0.50, before actions. Check the credit cost of each phone provider in the Clay app before you build the table.
Data and coverage
Both are aggregators, so neither owns the coverage outright. FullEnrich says it queries 25+ sources, stores no contact database, removes about 30% of raw data at verification, and averages a find rate of around 80% (its figure). Its search covers 800M people and 50M companies. Clay's pricing page says it connects to 150+ data providers and lets you combine them into multi-provider waterfalls; coverage is whatever your chosen providers return.
So the comparison is less "whose data" than "who designs the waterfall". FullEnrich picks the order for you. Clay lets you pick, which is more control and more work.
Workflow
FullEnrich takes a CSV, a HubSpot list, an API call or an MCP request and returns enriched rows. There is little to configure. Clay is a spreadsheet-like table where each column can be an enrichment, an AI prompt, a formula or a push to another tool. It can do what FullEnrich does, and it can also research accounts with Claygent, watch for job changes, score leads and send email through its sequencer. FullEnrich also lists Clay among its integrations, so some teams run FullEnrich as one step inside a Clay table.
Integrations
FullEnrich's FullEnrich integrations names HubSpot, Clay, Zapier, Make, n8n and Slack, plus API and MCP on every plan. Clay's plans put email campaign integrations on Launch and CRM auto-sync, HTTP API calls and webhooks on Growth; Clay API access is on Enterprise.
Verdict by team type
- Sales team that just needs mobiles on a list: FullEnrich. Predictable price per mobile, nothing to build.
- GTM engineer or RevOps building signal-led workflows: Clay. The orchestration is the product.
- Agency enriching lists for many clients: FullEnrich for raw enrichment, Clay if each client needs a custom workflow.
- Team already on Clay: test FullEnrich as a waterfall step and compare the data-credit cost per filled phone.
- Team that wants the number on the sequence record: Overloop, if you want the revealed phone number and the email and LinkedIn sequence on one prospect record. 5 credits per revealed number, only on a match. Overloop has no built-in dialer.
Our Clay alternatives guide covers the tools that replace Clay's other jobs.
A third option: Overloop
Overloop is our product, so weigh this section with that in mind. It is not a pure data vendor. Overloop finds the work email and the phone number of a prospect and runs the email and LinkedIn sequence from the same record, so the number does not have to travel through a CSV before anyone uses it.
For phone data, the Overloop phone number finder queries several data sources in turn and stops at the first match. A revealed number costs 5 credits, charged only when a number is found; an empty search uses no phone-search credits. Overloop finds emails with its email finder and sources new prospects from an advertised 450M+ B2B contact database. Credits are one shared meter across sourcing, email finding and phone reveal. Starter is $69 per user per month with 250 credits and Growth is $99 per user per month with 500 credits; the credit rules sit on the pricing page.
Where we lose: if you need Clay-style custom orchestration, Overloop is not a workflow builder; if you need bulk CSV enrichment through an API, FullEnrich is built for it. Overloop has no built-in dialer, so revealed numbers feed call tasks and CSV exports. We do not publish a phone match rate, because a rate measured on our lists would not predict yours. Run the reveal on 50 prospects you already know before you decide.
Want the mobile inside the sequence without building a table?
Overloop reveals phone numbers for 5 credits each, only when one is found, and sends the email and LinkedIn sequence from the same prospect record.

This is desk research, not a lab test. On September 28, 2026 we opened each vendor's official pricing page and the data pages linked below as a logged-out visitor, rendered them in a browser, and recorded plan prices, credits and the credit cost of a phone number. Price per number assumes every credit on the plan goes to phone numbers, which is the ceiling, not a typical month: emails, exports and other features draw on the same credits at most vendors. Coverage figures are what each vendor declares about its own data. We did not run a paid trial of either tool and we do not rank data accuracy, because no independent audit covering both was available. Methodology notes for the blog sit on our methodology page.

How much does a phone number cost in Clay?
Clay does not publish one figure. Phone lookups spend data credits at the rate of the provider you choose, plus actions. On Launch monthly, 2,500 data credits cost $125, or $0.05 each. Clay's guide says a fully enriched record typically costs 6 to 20 data credits and that phone numbers are the expensive part.
Does Clay charge if no phone number is found?
No. Clay's pricing FAQ says that if an enrichment returns no result, you are not charged data credits or actions. FullEnrich applies the same rule and also returns landlines without charging.
Can I use FullEnrich inside Clay?
Yes. FullEnrich lists Clay on its integrations page, so you can run it as a step in a Clay table. Compare its 10 credits per mobile against the data-credit cost of the providers already in your Clay waterfall.
Is Clay free?
Clay has a free plan with 500 actions and 100 data credits a month and up to 200 rows per table, but it does not include phone number enrichment. Phone enrichment starts on Launch, from $185 a month on monthly billing or $167 on annual billing.
What is cheaper for mobile numbers, FullEnrich or Clay?
FullEnrich's cost is published: $0.35 to $0.58 per mobile depending on volume. Clay's depends on the providers you pick and the actions your table spends, so compute it in the app for your waterfall before comparing.
Which tool puts the mobile number straight into an outreach sequence?
Clay can route rows into its sequencer or an integration once you build the workflow; FullEnrich returns enriched rows to your CRM or API. Overloop reveals a phone number for 5 credits, charged only when one is found, and runs the email and LinkedIn sequence from the same prospect record, with nothing to build.
