A domain with a small typo can look like yours while passing its own email authentication checks. Lookalike domain monitoring helps you find these variations and investigate potential impersonation beyond the protection DMARC gives your own domain.
Scan once, then keep watching
Enable Lookalike monitoring from Domains in your organization or MSP client workspace. Suped queues an initial scan, then checks weekly. Monitoring counts the domain toward your plan's domain limit, even when it has no email volume.

Enable lookalike monitoring for a domain to start its first scan and weekly checks.
Know where to investigate
Open Lookalike domains to see variations ranked by risk, with DNS provider comparisons, email configuration, website categories, and blocklist results. Filter the columns to focus your investigation, then download a CSV of the filtered results.

Lookalike results grouped under a monitored domain, with risk ratings, investigation signals, column filters, and CSV export.
Choose View data to inspect a variation's last scan, DNS records, email setup, website, and blocklist listings. Risk ratings help prioritize a review; they are not proof of fraud. Email records show configuration, not observed messages being sent.

The investigation view compares DNS providers and shows the last scan, risk rating, and email DNS records.
