From name to verified email in seconds
No spammy guesswork. Every candidate is probed against the live mail server before we hand it back.
Enter the inputs
First name, last name, company domain. That's it. Bulk uploads via CSV/XLSX are also supported.
Catch-all check
We first probe a random local part. If the domain accepts everything, we bail (and refund) rather than feed you false positives.
Pattern probing
We try the 9 most common business patterns in frequency order — firstname.lastname, flastname, etc. — via live SMTP.
Confirmed result
Stop on the first confirmed deliverable mailbox. See every pattern that was tried, with status and confidence.
Why Mailthentic's finder is different
Other tools guess and serve you a "most likely" address. We verify the exact mailbox before we hand it over.
Live SMTP confirmation
Every candidate is probed against the real mail server. Confirmed means the mailbox actually exists — not just that the pattern is statistically likely.
Catch-all aware
Domains that accept any address can't be searched reliably. We detect them upfront and refund your credits rather than guessing.
Custom probe patterns
Most companies use one of nine standard formats. For the rest, add your own templates using {first}, {last}, {f}, {l} placeholders. No extra cost.
Bulk uploads
Upload a CSV or XLSX with up to 5,000 rows. Header columns auto-detected — works with "First Name", "fname", "Given Name", "Company", "Website", and more.
Stop on first hit
Most finder runs terminate after 1–3 probes — the first match wins. No need to wait through every pattern just to learn one was the answer.
Refunds on dead ends
Invalid domain, catch-all, or infrastructure failure — we refund automatically. You only pay for searches that produced useful work.

Common questions
How does the email finder work?
Given a person's first name, last name, and the company's domain, we generate the nine most common business email patterns and probe each one via live SMTP. We stop on the first confirmed deliverable address.
Why only business domains?
Consumer providers like Gmail and Yahoo don't enforce a naming convention — usernames are arbitrary. Pattern guessing only works when employees follow a company-wide format, which is the norm at almost every business.
What if the domain is catch-all?
We probe with a random local part first. If the server accepts it, the domain accepts everything — we refuse to guess (any answer would be unreliable) and refund your credits automatically.
Can I add my own probe patterns?
Yes. Use {first}, {last}, {f}, {l} in templates like {first}.{last}.dev. Custom patterns don't cost extra.
How accurate is the result?
For confirmed hits, near 99 % — we verified the exact mailbox via SMTP. For Google Workspace and Microsoft 365 domains (which never confirm individual mailboxes by design), we return a best-guess with a 70-75 % confidence score.
How much does it cost?
Five credits per finder query — flat rate regardless of how many patterns we try. Refunded automatically for catch-all, invalid domain, and infrastructure failures. Sign up free with 5,000 credits.
Is bulk supported?
Yes — upload a CSV or XLSX with up to 5,000 rows. Each row is processed in parallel and you can download results as CSV. Header columns are auto-detected.
