Email Append & Verification

Find and verify a personal or work email for a name plus address, phone or company, with real SMTP-level verification rather than a syntax check.

EmailVerificationAppendHygiene

We find emails from our consumer and professional graphs, then verify them for real: SMTP handshake, catch-all detection, role-account flags and disposable-domain checks. Every result carries a verdict you can filter on, so a campaign is not paying for bounces.

For B2B, we infer the company pattern from known addresses on the domain and verify permutations until one is deliverable.

Sample rows

Illustrative and synthetic. Real samples for your geography are a reply away.

Abridged. The full data dictionary ships with every sample and lists every field, its fill rate and its source.

Used for

  • Email append to postal and phone files
  • List hygiene before a send
  • B2B contact discovery
  • Suppression of undeliverable records

How it is built

Candidates come from our graphs and pattern inference; verification runs through SMTP-level checks with catch-all probing so 'valid' means something. Inconclusive results are labeled, never guessed.

Questions we get

What hit rate should I expect?

It depends on input quality and on whether you want a personal or a work address. Rather than quote a range, we run a free test on a slice of your file and report the actual number.

Do you sell email lists?

We sell appends and verified contact fields on the datasets on this site. We do not sell anonymous email blasts.
