MX Lookup
Enter a domain to see its MX (Mail Exchange) records — the servers that accept email for it, sorted by priority.
What are MX records?
MX records tell the world which servers handle email for a domain. When someone sends mail toname@company.com, the sending server looks up the MX records for company.com and delivers to the server with the lowest priority number first. A domain with no MX records (and no fallback A record) cannot receive email at all — any address on it is undeliverable.
Why check MX records?
- Verify your own domain's email setup after DNS changes
- Debug why email to a certain domain bounces
- Identify which provider (Google Workspace, Microsoft 365, etc.) hosts a domain's email
Checking one domain is useful — but if you're cleaning a mailing list, you need mailbox-level answers. SkipBounce validates the full address, including a live SMTP check against these very MX servers.
