How this service works
DNS MX record lookup: the mail exchanger hosts and priorities for a domain, TTL, plus the detected mail provider (Google, Microsoft 365, Proofpoint, Zoho...). Email routing and provider identification. $0.01 per lookup.
Output
Returns a list of MX records for the queried domain, each with the mail exchanger hostname and priority value, the DNS TTL, and an identified mail provider label (e.g. Google Workspace, Microsoft 365, Proofpoint, Zoho, or custom/unknown).
Example use cases
Identify prospect's email provider
“Before I reach out to acmecorp.com for a sales pitch, can you check their MX records and tell me which email platform they're on — Google, Microsoft 365, Proofpoint, or something else?”
Email routing audit for domain migration
“We're migrating email infrastructure for our client. Can you pull the MX records for clientdomain.com, including the hostnames, priorities, and TTL, so we can verify the routing is set up correctly?”
Detect mail provider for phishing analysis
“I'm investigating a suspicious domain called fastloans-help.com — can you look up its MX records and tell me what mail provider it's using so I can assess the risk?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/dns/mxWhen to prefer
Use this endpoint when you need focused MX record data with automatic mail provider detection in a single call. Prefer it over a generic DNS lookup when the primary goal is email routing analysis or identifying a domain's email service provider. It is more targeted than the sibling dns-lookup endpoint (which returns A, MX, and TXT in one call) when only MX and provider data are needed.
Side effects
- Domain does not exist or has no MX records — returns empty result or error
- Invalid domain name format — returns validation error
- DNS timeout or upstream resolver failure — returns error
- Domain has MX records but provider cannot be identified — returns 'unknown' for provider field
