How OpenAI email is structured
OpenAI uses first-name-only @openai.com (first@openai.com) for most employees. Common-name collisions go to first.last@openai.com.
Hiring and recruiter domains
Recruiters: @openai.com directly.
Use a generator to build candidates
If you have a name and need the most likely OpenAI address, run it through the professional email address generator with openai.com as the custom domain. Verify the top candidates with any standard email-verification service before sending in volume — guessing right doesn't guarantee delivery.
Why format guessing works
Most large companies pick one convention and apply it consistently. Knowing one employee's address gives you every other employee's — the unlocking signal is the pattern, not the person. See the long-form piece on email formats for the six patterns that cover 95% of professional inboxes.
