Check for freemail and public email domains

Identify consumer mail providers when B2B fit or lead scoring depends on corporate domains.

Why this signal matters

B2B products often weight corporate domains higher in lead scoring. A public-domain flag at signup lets RevOps segment freemail signups, tune onboarding, and prioritize outbound without rejecting valid users.
