How this service works
Verify an email address: syntax check, domain MX lookup, disposable-domain and role-account flags. Use before sending or storing an address.
Output
Returns validation results for the submitted email address including: syntax check pass/fail, whether the domain has valid MX records, a disposable-domain flag indicating temporary or throwaway email services, and a role-account flag for addresses like admin@, noreply@, or support@.
Example use cases
Pre-send email list scrubbing
“Before I send this campaign, check if user-submitted address jane.smith@guerrillamail.com is valid — I need to know if it's disposable, has proper MX records, and passes syntax so I don't waste sends on junk addresses.”
Registration form email gating
“A new user just signed up with the email noreply@example.com — can you check whether that's a real deliverable address or a role account I should reject during registration?”
CRM data hygiene check
“I'm cleaning up our contact database — can you verify that info@fakecorp.xyz has valid MX records and isn't a disposable or role-based email before I keep it in our CRM?”
Technical details
Endpoint
GEThttps://agents.citiviewgroup.com/v1/email/verify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, lightweight email quality check before storing or sending to an address — especially when you want to catch disposable or role-based addresses in addition to basic syntax validation. Prefer this over full send-based verification (which sends an actual email) when you want a non-intrusive, read-only check at signup or data-import time.
Side effects
- Missing or malformed email parameter returns an error
- Non-existent domain with no DNS record may cause MX lookup timeout
- Some newer disposable domains may not yet be flagged in the blocklist
- Network errors during MX lookup may result in inconclusive domain status
