> Waterfall enrichment checks several data providers one after the other until it finds an email or a phone number. Here is how it works and which tools offer it in 2026.

**Quick answer:** waterfall enrichment checks several data providers one after the other, until one of them finds the email or phone number you need. [ColdIQ](https://coldiq.com/) runs it for you across 40+ providers and its own database of 700M+ B2B contacts. FullEnrich and BetterContact are cheaper options for emails and phones only.

- **For the most providers:** ColdIQ, with 40+ providers behind one API key, from $99 a month.
- **For a no-code table:** Clay, with 150+ providers inside its own app.
- **For emails and phones on a budget:** FullEnrich, from $29 a month, or BetterContact, from $15 a month.
- **For a large catalog:** Databar, with 100+ providers, from $99 a month.

## How Waterfall Enrichment Works

No single data provider has every email and phone number. One is strong on US tech companies. Another is strong in Europe. A third covers small businesses better.

A waterfall uses this. It asks the first provider. If that provider has no answer, it asks the second one, then the third, and so on. It stops as soon as one provider finds the data.

The result is more contacts found, and you usually pay only for the data you get.

## Why Teams Use It

- More emails and phone numbers found than with one provider.
- No need to sign a contract with each provider.
- One place to see which provider found what.
