Confirm the real format by verifying the top candidates.
Companies almost always use one consistent email format for every employee. If you know that one colleague is jane.doe@company.com, you know the CEO is firstname.lastname@company.com too.
This free tool applies the most common business email formats to the name and domain you enter and ranks them by how frequently companies use each pattern — so you can spot the likely format fast.
Knowing the likely format is the first step. To get the address that's actually deliverable, verify the candidates so you don't bounce and damage your sender reputation.
Emailchaser's free email verifier confirms which format lands, and our email finder returns the verified address for a specific person directly.
The format is set once by whoever administers the mail system — an IT admin in Google Workspace, Microsoft 365 or an on-prem directory — and every new mailbox is then created to match. Larger organisations lean on first.last because it scales to thousands of people without name clashes; small startups often use just first@ while there's only one Jane on the team. That single convention is exactly why knowing one person's address tells you almost everyone else's.
Across companies, first.last@company.com is the clear leader at roughly 38% of businesses, followed by first@company.com (about 17%), then first-initial-plus-last flast@company.com (12%) and firstlast@company.com (10%). The long tail — first_last@ with an underscore (6%), f.last@ (5%), firstl@ (4%) and the last-name-first variants at around 3% each — is where most bounced guesses come from. The tool ranks all ten patterns and, for domains it recognises, surfaces the format that company actually uses ahead of the generic ranking.
Real conventions vary more than people expect. Google, Uber and Stripe use plain first@, Cisco and Nvidia use flast@, and McKinsey uses first_last@ with an underscore — even though most of their big-tech and consulting peers standardise on first.last@. Whenever the domain you enter is on the tool's known list, that documented pattern is shown first and flagged, so you're not relying on the industry average for companies we can already pin down.
A single format can't cover two people with the same name. When a company already has jane.doe@company.com, the second Jane Doe usually gets a tie-breaker: a middle initial (jane.a.doe@), a number (jane.doe2@) or a shortened variant (janed@). Predicted addresses for very common names are the most likely to miss for this reason, so verify before you trust one.
The other frequent miss is the name itself. Directories are usually built from legal names, so Robert may be robert.smith@ even though he signs off as Bob, and William might be william@ or bill@. Accented and hyphenated surnames get flattened too — José becomes jose, and Smith-Jones can appear as smithjones or simply smith. If your first candidate doesn't verify, retry with the person's formal first name and an un-hyphenated, unaccented surname.
Usually the format is right and the domain is the problem. Plenty of companies send mail from a domain that isn't the one on their website — a shorter brand domain, a country domain for a regional office, or a dedicated mail subdomain. Goldman Sachs, for example, uses gs.com rather than goldmansachs.com. Enter the domain that actually appears after the @ in a known address, not just the marketing site's URL.
Even with the right pattern and domain, a mailbox can still reject mail: the person has left, they use a role alias like sales@ or info@ instead of a personal address, or the company changed its convention years ago and long-tenured staff kept the legacy format. A catch-all domain muddies things further by accepting everything, so a technically valid address may never reach a real person. The fix is the same every time — run your top two or three candidates through Emailchaser's free email verifier and send only to the one that resolves to a real, deliverable mailbox.
Manually testing jane.doe@, jdoe@ and janedoe@ by firing off emails burns your sender reputation with every bounce and quietly signals to the recipient that you're guessing. Starting from the known format collapses that guesswork: you get the handful of realistic patterns ranked by how often companies use each one, so you verify two or three candidates instead of blindly emailing ten.
When you only have a name and a domain, this finder and the email permutator do complementary jobs — the permutator generates every possible combination for bulk checking, while the format finder narrows to the likeliest patterns first. If you'd rather skip straight to a confirmed address for one specific person, the email finder returns the verified email directly.
What is a company email format?
A company email format is the consistent pattern an organisation uses to build every employee's email address — for example first.last@company.com or flast@company.com. Once you know the pattern, you can work out almost anyone's address at that company.
How do I find a company's email format?
Enter a person's first name, last name and the company's domain above. The tool shows the most common business email formats applied to that name, ranked by how often companies use each one. Verify the top candidates to confirm the exact pattern.
What is the most common business email format?
first.last@company.com is the most common business email format, used by roughly a third of companies. first@company.com and flast@company.com (first initial + last name) are the next most common. Our tool ranks every format by real-world prevalence.
Is the company email format finder free?
Yes — it's free, requires no signup, and runs in your browser. To confirm which format a specific company actually uses, verify the generated addresses with Emailchaser's free verifier.
What email format does a company use?
Most companies apply one of about ten patterns to every employee, and first.last@company.com is by far the most common, followed by first@company.com and first-initial-plus-last (flast@company.com). The exact one varies: Google uses first@, Cisco uses flast@, and most large firms use first.last@. Enter a name and the company's domain above to see the likely format, then verify it to confirm the pattern that company actually uses.
How accurate is the company email format finder?
It predicts the pattern rather than guaranteeing a live mailbox. For domains it recognises, the tool shows the convention that company is known to use; for everything else it ranks the ten common formats by real-world prevalence, so the top guess is right for most companies. Accuracy becomes near-certain once you verify the top candidates, which confirms which format resolves to a real, deliverable address.
Do all employees at a company use the same email format?
Almost always — the format is set once at the mail-server level and applied to every new mailbox, which is exactly what lets you work out one address from another. The exceptions are duplicate names (a second Jane Doe gets a tie-breaker like jane.doe2@), staff who joined through an acquisition and kept a legacy domain, and shared role addresses such as sales@ or support@. Executives sometimes have a vanity alias on top, but the underlying pattern still holds.
Why does the finder suggest a different address than the one I already have?
Usually the person's name doesn't map cleanly to the pattern — they go by a nickname (Bob for Robert), have a hyphenated or accented surname, or share a name with a colleague and were given a numbered variant. It can also mean the company sends from a different domain than its website, or changed its format over the years. Trust the address you can verify: run both through the email verifier and use whichever one is deliverable.
