How this service works
Validate up to 500 email addresses in one paid request using syntax, MX, disposable, role-account and domain-risk checks.
Output
Returns a structured validation result for each submitted email address, including flags for syntax validity, MX record presence, disposable domain status, role-account detection, and domain-risk signals — covering up to 500 addresses per call.
Example use cases
Pre-campaign email list scrubbing
“I have a list of 400 email addresses I collected for our newsletter — can you run them all through validation and tell me which ones are invalid, disposable, or role accounts so I can clean the list before we send?”
New user signup fraud screening
“We just got a batch of 250 new signups overnight and I want to check all their email addresses for fake or disposable domains and flag any role-based accounts like admin@ or noreply@ before we provision their accounts.”
CRM data quality audit
“Can you validate these 180 email addresses from our CRM export and give me a breakdown of which ones have bad syntax, missing MX records, or come from risky domains so we know which contacts to remove?”
Technical details
Endpoint
POSThttps://agent-vending-production.up.railway.app/v1/email-risk/bulk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to validate multiple email addresses at once and want to minimize cost and latency compared to making individual validation calls. It is ideal for list cleaning, batch onboarding validation, or pre-send campaign hygiene where you have 2–500 emails to check in a single operation. For a single email address, prefer the sibling single Email Validate endpoint instead.
Side effects
- Empty or missing emails array returns a validation error
- More than 500 emails in the array exceeds the batch limit and is rejected
- Malformed email strings may return syntax-fail without MX lookup
- Payment not included or insufficient funds returns HTTP 402
- Temporary DNS lookup failures may cause MX check timeouts for some addresses
