<Update label="June 15, 2026">
  **Lower-cased company and work-email domains**

  Company domains and work-email domains on participant profiles are now stored and returned in lowercase. Existing profiles have been back-filled, so domain comparisons (for example, matching a participant's work email to a company) behave consistently regardless of the casing the participant originally entered.

  See [Retrieve a participant's profile](/profiles/retrieve-participant-profile).
