What are MX records?
MX (Mail Exchange) records are DNS entries that specify which mail servers should receive email for a domain. Lower priority numbers indicate higher preference.
What is the priority value?
Priority determines the order mail servers are tried. Lower numbers are preferred. If priority 10 fails, the sender tries priority 20, and so on.
Can you detect the email provider?
Yes, we identify common providers like Google Workspace, Microsoft 365, Zoho, and others based on MX record patterns.
What if a domain has no MX records?
Domains without MX records typically cannot receive email. Some may fall back to A records, but this is uncommon.
How current is the data?
MX lookups are performed in real-time against authoritative DNS servers, so you always get current records.
Can I use this for email verification?
MX lookup confirms a domain can receive email. Combine with our Email Validator for full address verification.
