01HOW EMAIL

How email format finding works

Most companies use a consistent email pattern across employees. If you know one person's email, you can usually guess everyone's. We generate the most common patterns for the name + domain you enter.

PatternExamplePrevalence
first.lastjane.doe@acme.comMost common (~35%)
firstlastjanedoe@acme.comCommon
flastjdoe@acme.comCommon
firstjane@acme.comSmall companies
f.lastj.doe@acme.comLess common
02ALWAYS VERIFY

Always verify before you send

A format guess is just that — a guess. Sending to a guessed address that doesn't exist causes a hard bounce, which hurts your sender reputation. Always verify the address before adding it to a campaign.

KillBounce gives you 100 free verifications — enough to confirm which guessed format is real before you send a single email.

Frequently asked

Answers to the questions teams ask first

Is this email format finder free?

Yes — free, no signup. Enter a name and domain to get the patterns.

Are these real email addresses?

They're the most likely patterns based on common conventions — not confirmed addresses. Verify before sending to avoid bounces.

How do I know which format is correct?

Verify each guess. KillBounce confirms which one actually exists via a live SMTP check — 100 free verifications with signup.

Why does verifying matter?

Sending to a guessed-but-wrong address bounces, and bounces damage your sender reputation. Verify first, send second.
