FullEnrich vs Clay for Waterfall Enrichment

FullEnrich and Clay come up in most conversations about data enrichment. Both find email addresses and phone numbers, and both are meta providers.

What is a meta provider?

To find phone numbers and email addresses, you need access to a large database of contacts. There are two ways to get that access: own the database, or resell access to someone else's. Traditional data providers sell their own data; meta providers resell access.

Why meta providers

Being a meta provider comes with several advantages. The biggest is the ability to chain multiple datasets into waterfalls. Waterfalls increase coverage without meaningfully increasing cost, because you are normally billed only for successfully resolved requests.

A waterfall tries provider 1 first. If provider 1 does not have the result, the request moves to provider 2, and so on until a provider returns a result.

Waterfall enrichment flow: a lookup falls through provider 1 and
provider 2 without results and without cost, provider 3 returns a result
and is the only provider billed, and the result then passes a
verification step where it is kept or discarded

The motion has another advantage. Even when a provider returns a result, you can add a verification step on top. You can validate the email address with a provider like ZeroBounce, or check a phone number for common markers of a false entry.

If validation fails, the result is discarded.

Clay and FullEnrich both use this exact strategy to find contact data. In fact, FullEnrich is one of Clay's listed providers. If you purchase a Clay license, you get access to FullEnrich too.

Comparing on cost

A phone number through FullEnrich-inside-Clay costs roughly 95¢. The same number directly from FullEnrich costs an average of 55¢ (👉🏽 a phone number on pipe0 costs an average of 8¢).

Don't expect the FullEnrich you reach through Clay to match the native product 1:1, either. FullEnrich's own platform runs 20+ providers per waterfall. Clay's native waterfall runs roughly 14 providers, of which FullEnrich is only one. It is common practice to sell meta providers like Clay a slimmer version of your waterfall.

Even reaching FullEnrich on Clay with your own API key now incurs costs, after Clay's 2026 pricing change that introduced actions.

Here is how the list prices break down, using each vendor's published plans and per-enrichment rates:

	FullEnrich	Clay	pipe0
Entry plan	$29/mo, 500 credits	$167/mo, 3,000 data credits + 15,000 actions	$49/mo, 1,600 credits
Top self-serve plan	$55/mo, 1,000 credits	$446/mo, 6,000 data credits + 40,000 actions	$999/mo, 34,000 credits
Price per credit	5.5–5.8¢	from 5¢, plus actions	2.9–3.1¢
Work email, on success	1 credit ≈ 5.5¢	~2–5 credits ≈ 10–25¢	0.5 credits ≈ 1.6¢
Mobile number, on success	10 credits ≈ 55¢	≈ 95¢ via FullEnrich-inside-Clay	3 credits ≈ 9¢

Prices come from each vendor's pricing page and docs as of August 2026. Clay publishes no flat rate card; costs display in-product, and Clay's own waterfall guide prices individual provider lookups at 20¢ to $1.00. The pipe0 numbers are pipe-catalog list prices; high-volume billing lowers them further. On this math, pipe0 comes out roughly 7x as cost effective. All three tools have free tiers, so run the same 50 rows through each and check.

Stacking margins

The chain of providers now looks roughly like this:

B2B data provider
Meta provider
A meta provider inside a meta provider (FullEnrich inside Clay)

This is the triple-margin pattern, and it bloats the cost per enrichment. With meta providers, you generally trade cost for coverage. Maintaining a large waterfall yourself is a genuinely annoying problem that carries a cost category of its own. Purchasing many individual providers, stitching them together, and working with rate limits and various provider credit balances is hard and expensive.

Meta providers know this and charge accordingly.

Clay goes beyond enrichment

Clay is more than a meta provider. It is a full automation framework that lets you perform actions like sending emails or Slack messages and lets you define logic around the data you retrieve.

Should you use either?

At pipe0 we spend a lot of time benchmarking enrichment providers, comparing their performance, and discussing rates. We have also built enrichment systems at companies like Cursor and Cloudflare.

We find it difficult to recommend either platform. The margin charged per enrichment is still 4-5x where it should be.

That said, for low-volume enrichment where accuracy matters, you can consider FullEnrich. If your use case goes beyond retrieving email addresses and phone numbers, consider Clay.

We also want to encourage you to try pipe0: a fairer margin profile and higher coverage and accuracy.
