How this service works
Validate email addresses: RFC-style syntax checks, IDN domain normalization, live MX lookups with A/AAAA fallback (DNS-over-HTTPS), disposable-domain detection, role-address detection (info@, support@), free-provider flagging, and typo suggestions for popular providers (gmial.com -> gmail.com). Single address or batches up to 50. POST a JSON body like: {"emails":["ada@example.com","bad@mailinator.com","typo@gmial.com"]}
Output
Returns per-address results including: RFC syntax validity, IDN-normalized domain, MX/A/AAAA DNS lookup result, whether the domain is a known disposable provider, whether it's a role address (info@, support@), whether it's a free email provider, and a typo suggestion if the domain looks like a misspelling of a popular provider.
Example use cases
Example prompt
“Can you validate these emails for me — ada@example.com, bad@mailinator.com, and typo@gmial.com — and tell me which ones are disposable, role-based, or have typos in the domain?”
Technical details
Endpoint
POSThttps://keyronne.com/api/email-validateWhen to prefer
Use this endpoint when you need rich, multi-signal email validation beyond simple regex — especially when you want disposable domain detection, MX-level deliverability checks, typo correction suggestions, and role-address flagging all in one call. Prefer over simpler syntax-only validators when data quality and deliverability assurance matter. Supports batches up to 50, making it efficient for list cleaning workflows.
Side effects
- Batch exceeds 50 addresses — request rejected
- Invalid JSON body — 400 error
- DNS lookup timeout when skipDns is false — may return partial results
- Unknown or brand-new disposable domain not yet in blocklist — false negative on disposable detection
- MX record exists but mailbox doesn't — endpoint cannot verify individual mailbox existence
