Email Format Finder

Most companies use one of a handful of email formats. Enter a first name, last name and domain to see the likeliest patterns — a starting point for reaching the right person.

Need more than the free basics? These are educated guesses, not verified addresses. To actually find and verify real emails at scale — with a 270M+ contact database and bounce checking — a tool like Apollo does it properly.

A guess, not a verified address

This lists the common formats companies use, but it does not check whether any address actually exists or deliverable. Sending to a guessed address risks bounces, which hurt your sender reputation. Treat the output as candidates to verify. For real prospecting — finding the right person and confirming the email lands — use a sales-intelligence tool with built-in verification like Apollo.

Frequently asked questions

Does this verify the email exists?

No. It only shows the common patterns companies use. Always verify an address before emailing — guessed addresses bounce and damage your sender reputation.

What's the most common email format?

first.last@company.com and flast@company.com are the most widespread, but it varies. This tool lists the likeliest options to test.

How do I find verified emails at scale?

Use a sales-intelligence platform like Apollo that finds contacts and verifies deliverability, rather than guessing and risking bounces.
