Email Format Finder

The single most common business email format is first.last@company.com (for example jordan.lee@acme.com), used by roughly 48% of B2B addresses. The next most common is flast@company.com (jlee@acme.com) at about 27%. Together those two cover roughly three-quarters of business email addresses.

Most companies use one consistent pattern for every employee, so once you know one person's address you know everyone's. Enter a name and the company domain here to generate the likely candidates ranked by how common each pattern is, then verify which one actually exists before you send.

An email permutator takes a first name, last name, and company domain and generates every plausible address combination (jordan.lee@, jlee@, jordan@, j.lee@ and so on). It produces candidates, not confirmed addresses, so the output should always be verified before use.

Yes, and you should. A generated format is a best guess until it is checked. Run the top candidate through an email verifier, which checks the domain's mail servers and the specific mailbox in real time and returns whether it is deliverable, without sending anything to the address.

Yes. Larger organizations standardize on formal patterns: first.last@ becomes far more common at big companies, while small teams are much more likely to use just a first name (first@). If a small startup's addresses do not match first.last@, try first@ next.

A guess is only as good as its verification. Because the top two formats cover about three-quarters of business email addresses, a ranked guess is often right, but the only way to know is to verify the specific mailbox exists. Treat the generated list as ranked candidates and confirm the winner before sending.

Generating and verifying a professional email address is generally legal; it is sending that the law governs. Under US CAN-SPAM you may email a business contact if you identify yourself, honor opt-outs, and include a valid physical postal address; under GDPR, B2B outreach relies on legitimate interest and requires the contact be relevant to the person's role and that you document how you got the address. Consent-based regimes are stricter: UK/EU ePrivacy and PECR can require prior consent to email individuals and sole traders, and Canada's CASL is consent-based with no legitimate-interest exception. This is general information, not legal advice, so confirm the rules for the recipient's country and only contact people for genuine, relevant business reasons.

A format finder shows you the pattern a company uses and generates likely addresses from a name; an email finder searches for a specific, already-known person's verified address directly. Use the format finder when you know the name and company but not the address; use the email finder when you want a confirmed match in one step.
