Email Provider Lookup
Enter any domain to identify its email provider. No signup required.
What this tool detects
This free lookup queries the domain's MX and SPF records to identify the email provider powering it. It distinguishes between 150+ providers including Google Workspace, Microsoft 365, Zoho, Fastmail, OVH, and more.
Unlike email verification, this tool never contacts the mail server. It performs passive DNS analysis only — safe, fast, and GDPR-compliant.
