Verified work emails,

9-source waterfall

Providers are queried in confidence order and the first verified result wins — not a permutation guess, a confirmed address.

Deliverability you can trust

Syntax, domain, and live-mailbox checks run on every address. Catch-alls are flagged with their own status, never hidden.

Single or bulk

One lookup, or a bulk job over a CSV that returns deduplicated, ready-to-send addresses with a webhook callback.

ENDPOINTS

The endpoints you'll actually use.

POST/v1/email/findFind a verified work email from a name and domain.

01
Add email finding to your product

Give your users one-click verified emails inside your sales or recruiting tool, powered by Bunlead behind the scenes.

02
Clean lists before you send

Verify an entire outbound list programmatically so bounces never touch your sender reputation.

03
Automate on new records

Find and verify an email the moment a name and company land in your pipeline, then hand off to your sequencer.

FAQ

Developer questions, answered.

Is this just an email permutator?

No. Permutators generate guesses and leave you to test them. The Email Finder API queries a verified database first, and any deduced address still passes a live mailbox check before it is returned.

Do I pay when no email is found?

No. A lookup that returns no verified result is free. You are only billed for addresses that pass verification.

How are catch-all domains handled?

Catch-all addresses are returned with a distinct status and confidence score rather than a false "verified" flag, so you decide how to treat them.

Is finding work emails compliant?

Bunlead applies GDPR- and CCPA-aligned handling to professional contact data across its whole graph. You remain responsible for how you use the data in outreach.
