How this service works
Validates one email (email=) or up to 50 (emails=comma list, same price): RFC 5322 syntax, normalized form, MX records (A fallback), disposable, role account, free provider, typo suggestion, and a deliverable/risky/undeliverable verdict with reasons. No SMTP probing.
Output
A JSON object per email containing: normalized email form, domain, syntax validity, MX record status and records, disposable flag, role account flag, free provider flag, typo suggestion (or null), a verdict of 'deliverable'/'risky'/'undeliverable', and an array of reason codes explaining the verdict.
Example use cases
Signup form email gating
“Before we create the account, check whether j.doe123@gmial.com is a real, deliverable email — flag it if it looks like a typo, is a disposable address, or the domain doesn't accept mail.”
Bulk lead list hygiene
“I have this list of 40 emails from our lead gen campaign: alice@acme.com,bob@mailinator.com,carol@outlook.com,... — can you validate all of them and tell me which ones are undeliverable or risky so we can clean the list before outreach?”
Detecting role-based or free-provider signups
“Check the email info@startup.io and tell me if it's a role-based address, whether the domain has working MX records, and whether we should flag it as risky for our B2B SaaS signup flow.”
Technical details
Endpoint
GEThttps://webtools.genexxis.com/email-validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-signal email validation (syntax + MX + disposable + role + free provider + typo suggestion + verdict) in a single call without SMTP probing. It supports up to 50 addresses per call at a flat rate, making it cost-effective for bulk hygiene. Prefer it over basic regex validators when you need actionable deliverability verdicts with reasons, or over SMTP-probing services when you want non-intrusive validation.
Side effects
- Missing both email and emails query parameters — returns an error response
- More than 50 addresses in the comma-separated emails list — likely rejected or truncated
- Malformed comma-separated list — may cause partial or error response
- Network or DNS lookup timeout for MX records — may return degraded verdict
- Unusual or internationalized domain names — MX resolution may be unreliable
