How this service works
Validate one email address without sending mail: syntax, MX, disposable, free webmail, role account, SPF/DMARC. Returns deliverable/risky/undeliverable/invalid with score.
Output
Returns a deliverability verdict (deliverable, risky, undeliverable, or invalid) with a numeric risk score, plus individual signal flags: syntax validity, MX record presence, whether the address is from a disposable provider, a free webmail service, or is a role account (e.g. info@, noreply@), and SPF/DMARC configuration status for the sending domain.
Example use cases
Lead quality check before CRM entry
“Before I add this lead to my CRM, can you check if the email address they gave me — marketing@freemail.xyz — is actually deliverable or if it's a disposable or role account I should reject?”
Sign-up form abuse prevention
“A user just registered with the email temp9182@guerrillamail.com — can you tell me if that's a throwaway disposable address so I can decide whether to block the sign-up?”
Email campaign list hygiene
“I'm about to send an email campaign and I want to verify that jenny.smith@contoso.com is a real, deliverable address with valid MX records and not flagged as risky before I include it in the list.”
Technical details
Endpoint
GEThttps://gogeta2-u35175.vm.elestio.app/agents/v1/email/check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-email, non-sending validation that goes beyond syntax checking — specifically when you need MX verification, disposable/free webmail detection, role account flagging, and SPF/DMARC checks all in one call. Prefer it over basic regex validators when list quality, fraud prevention, or deliverability accuracy matters. It is not a bulk batch validator and does not send a probe email.
Side effects
- Malformed email input returns invalid verdict immediately
- Domain with no MX records returns undeliverable
- Timeout resolving DNS records may return an error or degraded result
- Edge-case international/IDN domains may not resolve correctly
- Known disposable provider lists may lag newly created throwaway domains
- SPF/DMARC check may return partial data if DNS is slow or rate-limited
