Google Workspace checker: common questions
Can you tell Workspace from consumer Gmail?
Yes. Consumer Gmail runs on gmail.com with its own mail servers; Workspace runs on the company domain and publishes different MX and DKIM records.
Do you check individual users?
No. Detection is per company domain only — we never probe whether a specific person has an account.
What if a company uses both Google and Microsoft?
It happens. Both are reported independently, with the evidence for each.
