A company email format is the naming convention an organisation applies to every staff mailbox. It is set once at the mail-server level and used for each new hire, which is why one known address usually reveals how every other address at that company is built. Unlike a personal Gmail or Outlook account, where the user picks their own username, a work address follows a rule.
The conventions that account for the overwhelming majority of corporate mailboxes are:
first.last, as in jane.smith@company.com, the most widespread convention overallflast, as in jsmith@company.com, common in large enterprises and consultanciesf.last, as in j.smith@company.com, frequent in European organisationsfirstlast, as in janesmith@company.comfirst, as in jane@company.com, typical of startups and small teamsPlenty of employers run more than one convention at the same time. A rule adopted a decade ago often survives alongside a newer one, acquisitions arrive with their own, and duplicate names force exceptions. That is why treating any single format as definitive is a mistake, and why the only reliable answer comes from checking.
Sending to addresses you have guessed is the quickest way to damage a sending domain. Every hard bounce tells mailbox providers your list is stale, and the resulting reputation hit affects delivery to your entire audience, not just the addresses that failed. A verification step in front of your outreach removes that risk entirely. For volume work, the bulk email verifier cleans a whole CSV at once, and the real-time verification API keeps unverified addresses out of your CRM in the first place.
Enter any name and the company’s domain in the finder above. It applies all thirteen common corporate naming conventions and gives you each candidate address, which you can then verify. If we hold a dedicated page for that employer you will also find it in the directory below.
Yes. Generating address formats is free and needs no account. Verification runs on the free verifier with a daily allowance, and a free account adds 100 credits for larger checks.
A generated address is a well-informed candidate, not a confirmed one. Any tool claiming certainty from a name and a domain alone is overstating what it knows. Accuracy comes from the verification step, where the mail server itself confirms whether the mailbox exists.
Yes. Upload a CSV to the bulk email verifier, or call the verification API from your own systems to check addresses programmatically.
The email format checker validates whether a single address is syntactically well formed. This finder is about a company’s naming convention, meaning which shape its addresses take, and whether a specific mailbox actually exists.
Dedicated pages for 138 employers, grouped by industry. Each one lists that company’s address conventions and lets you build and verify a specific address.
15,082 domains where we have measured the address format from addresses our own verifier confirmed as deliverable, not inferred from a generic pattern list. Each page states the convention, the share of classified addresses using it, and the counts behind that share.
