How this service works
Mail exchanger lookup for Sales operations: Return the domain MX hosts and their delivery priorities. DNS data only; does not send email or verify that an inbox exists.
Output
Returns a list of MX (mail exchanger) host records associated with the queried domain, each paired with its delivery priority integer. Higher priority values indicate lower preference in DNS convention. No email is sent and inbox existence is not verified — this is pure DNS data.
Example use cases
Validate email routing before outreach
“Before we start our sales outreach campaign, can you look up the MX records for hubspot.com so I know which mail servers handle their inbound email and what priorities they're set to?”
Enrich prospect domain with mail server data
“I'm building a prospect profile for acme.com — can you pull their DNS MX hosts and delivery priorities so I can understand their email infrastructure?”
Verify domain has working mail exchangers
“We're about to send a batch of cold emails to leads at stripe.com — can you check their MX records to confirm the domain actually has mail exchangers configured and what they are?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-domain-mx-records-sales-operations?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need raw DNS MX record data for a domain as part of sales enrichment, email deliverability pre-checks, or infrastructure reconnaissance. Prefer this over full email verification services when you only need routing/infrastructure data and not inbox-level validation. Ideal for lightweight, low-cost ($0.01) domain mail server lookups at scale during sales prospecting workflows.
Side effects
- Domain does not exist or has no MX records — returns empty list or DNS NXDOMAIN error
- Invalid domain format supplied — returns validation error
- DNS resolution timeout — transient failure, retry recommended
- Domain has MX records delegated to a third-party provider that may not reflect the company's primary mail infrastructure
