Email Format Finder
Discover Any Company's Email Pattern
AI researches a company's publicly visible email addresses to detect their format. Know whether they use firstname@company.com, f.lastname@company.com, or something else — before you send.
How Email Format Detection Works
AI searches the public web
Our AI scans company websites, team pages, press releases, conference sites, and public documents for any employee email from this domain.
Pattern recognition
When an email is found, the AI reverse-engineers the format (e.g., john.doe@company.com → firstname.lastname pattern).
Confidence-rated result
You get the format, an example email, the source, and a confidence rating — plus suggestions if the format couldn't be determined.
When to Use an Email Format Finder
- Cold outreach to a new company — quickly learn their email convention before reaching out
- Sales teams targeting enterprise accounts — large companies often use non-standard formats
- Recruiters sourcing passive candidates — verify the format before contacting executives
- Startup founders doing founder-led sales — don't waste time guessing wrong emails
Frequently Asked Questions
How do I find a company's email format?
Enter the company domain and we use AI to research the company's known email patterns. If an employee email is publicly visible anywhere on the web, our tool can detect the format (e.g. firstname.lastname@company.com).
Does this work for any company?
It works best for companies with public-facing employees — those whose emails appear on team pages, press releases, PDF reports, or conference websites. Small startups with no public email footprint are harder to detect.
