Choose Immune when

Public and shared inboxes are the pain

  • Group aliases like support@ still attract outreach Gmail does not treat as spam.
  • You want verification for strangers without training a custom Gmail content rule set.
  • Some mail should never touch a Gmail UI and should go straight to a helpdesk.

Google Workspace may still fit when

You need something else

  • All important mail already lives in Gmail for known contacts only.
  • You are happy managing abuse with spam folders and user reports alone.
