How this service works
Email domain routing check for Vendor screening: Validate an email address shape and check whether its domain has MX records. DNS data only; does not send email or verify that an inbox exists.
Output
Returns whether the email address is syntactically valid and whether the email's domain has MX records in DNS. Does not send email, does not confirm an inbox exists, and does not authenticate the recipient — DNS-layer routing check only.
Example use cases
Vendor onboarding email pre-check
“We're onboarding a new supplier and their contact is listed as accounts@tekfabricators.net — can you confirm that email address is well-formed and the domain has MX records before we send them the contract?”
Contractor database email audit
“I have a contractor email to screen before we add them to our system: finance@deltabridge-consulting.com — please check if the format is valid and whether that domain has mail routing set up.”
Procurement screening for suspicious domain
“Can you run a DNS and format check on the vendor email operations@qualitysupply-ltd.com? I want to know if the domain is actually configured to receive email before we proceed with them.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-domain-email-domain-check-vendor-screening?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, fast, DNS-only sanity check on a vendor or counterparty email address — particularly during onboarding workflows where you want to catch bad domains before committing to communication. Prefer this over full inbox verification services when you only need format and MX routing confirmation, not full deliverability testing or SMTP probing. It is ideal for automating vendor screening pipelines where cost and speed matter.
Side effects
- Invalid email format — syntactically malformed address returns a validation failure
- Domain has no MX records — domain exists but is not configured for email routing
- Domain does not exist — NXDOMAIN response from DNS lookup
- DNS timeout — temporary lookup failure due to DNS infrastructure issues
- Missing or empty email field — request rejected due to missing required parameter
