How IBM email is structured
IBM uses first.last@ibm.com as primary. Country codes appear for non-US employees (e.g., first.last@in.ibm.com for India).
Hiring and recruiter domains
Recruiters: @ibm.com or @us.ibm.com.
Use a generator to build candidates
If you have a name and need the most likely IBM address, run it through the professional email address generator with ibm.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.
