Contact / Waterfall Agent

Why it works

Built to find the contact that single-database tools miss.

Every provider has coverage gaps. The Contact Agent queries 10+ in parallel, cross-validates the results, and falls back to live web search when every database comes up empty — so "not found" is almost never the final answer.

Ten providers, one answer.

HunterMail, LeadMagic, FindyMail, Prospeo, and more — queried in parallel, cross-validated before delivery. When providers disagree, Tnuki surfaces the conflict instead of picking silently.

Live-web fallback for the hard ones.

When every database misses, Tnuki searches company team pages, LinkedIn, press releases, and bios — the places your contact actually shows up. The last-mile resolution most tools can't do.

Deliverability-checked before you see it.

Every email passes a live SMTP check before it reaches your draft. No stale-data bounces burning your sender reputation on contacts that moved six months ago.

Pay only when it works.

Failed lookups cost you nothing. You're not paying credits for "not found" results you can't use — unlike every single-database tool that charges per query regardless.

Frequently asked

Common questions about Tnuki Contact / Waterfall Agent

How is this different from ZoomInfo or Apollo?

ZoomInfo and Apollo rely on a single proprietary database, refreshed on monthly or quarterly cadences. The Waterfall Agent queries 10+ providers plus the live web per lookup — so if your contact just changed jobs yesterday, you see the new email today.

What happens if no provider has the contact?

The agent falls back to live web search — company sites, LinkedIn, press releases, public bios. Most 'not found' results from other tools are resolvable this way.

How do I know the email will actually deliver?

Every email runs through a live SMTP deliverability check before it reaches your draft. Results are flagged with confidence levels so you know when to send and when to verify further.

What about phone numbers and LinkedIn profiles?

Included in the same waterfall. You get email, phone, LinkedIn, title, and company — validated together, delivered in one row.
