How this service works
MX Lookup - Call when you need to know who handles a domain's email - checking deliverability, identifying a mail provider, or debugging a bounce. Send the domain. Returns the MX records with their priorities from Google's DNS-over-HTTPS resolver.
Output
Returns the raw DNS resolver Answer array as JSON, containing MX record entries with each mail exchange hostname and its priority value as returned by Google's DNS-over-HTTPS API.
Example use cases
Identify email provider for domain
“What mail servers does notion.so use? Look up their MX records and tell me the hostnames and priorities.”
Verify email deliverability setup
“Check the MX records for my domain acmecorp.io — I want to confirm the mail exchange entries are set up correctly before we start sending campaigns.”
Research competitor email infrastructure
“Can you pull the MX DNS records for shopify.com so I can see which email provider they're routing through?”
