A Smarter Way to Find Verified Contacts

Try every source, not just one

Your contact request goes to data providers one at a time. If Provider A doesn't have the email, Provider B gets queried. Then C, then D, all the way through 20+ sources until a match is found.

Verified before you see it

Single-provider tools return unverified guesses. Waterfall enrichment verifies every match before returning it. FullEnrich runs triple verification: syntax check, MX record validation, and SMTP handshake. Result: <1% bounce rates.

Only pay when we find data

The waterfall stops at the first verified match, so you never pay for redundant lookups. Credits are only deducted when a verified email or phone number is actually found.

waterfall_chart How It Works

How Waterfall Enrichment Works

Five steps from raw contact to verified data — across 20+ providers.

Step 1

Submit a contact

Provide a name and company domain — from a CRM export, LinkedIn list, CSV upload, or API call.

Step 2

Provider sequence activates

FullEnrich routes the request through 20+ data providers in an optimized sequence. Regional specialists are prioritized based on the contact's location.

Step 3

Sequential cascade

Each provider is queried one at a time. If Provider 1 doesn't have the data, Provider 2 is tried. Then Provider 3 — cascading through the entire stack until a match is found.

Step 4

Triple verification

Every found email passes three independent checks: syntax validation, MX record verification, and SMTP handshake. Phone numbers are validated as active mobile lines, not landlines or switchboards.

Step 5

Verified data returned

Only high-confidence, verified contact data is delivered. Work emails, personal emails, and direct mobile numbers — ready for outreach.

Go where your competitors can't

Most companies use the same data vendors. They are all contacting the same leads. Avoid competition by reaching into your untapped market and increase your TAM by 78%.

Lead grid highlighting untapped prospects outside competitor reach
Expand internationally with ease

Some data vendors are way better than others in specific regions and industries. A provider that worked well with your original customer base won't necessarily be the best for expanding to new markets.

20+ data sources for the price of 1

Access the world's best data vendors from a single account, interface and subscription.

verified_user Powered by verification agents

Every Email. Every Mobile. Verified.

Triple email verification

Three independent engines must agree. One disagreement removes the email.

Catch-all resolution

Deliverability confidence

Every delivered email carries its own bounce probability, so you know your expected bounce rate before you send.

j.moreau@dataiku.com 0.0% bounce
s.kim@figma.com 0.0% bounce
m.weber@personio.de 0.0% bounce
Mobile first, no landlines

You only pay for mobile numbers. Landlines found are free.

Active lines only

Every number is checked with the carrier network. Dead lines are removed.

Owner-name match

Line ownership is matched against your lead’s name, so reps never call a stranger.
