How this service works
Verifies an email address and its domain with DNS-based risk checks: MX, disposable-domain, role-account, SPF, DMARC, and DKIM signals. Privacy-safe: does not probe the recipient mailbox. Use it as an email verifier, email verification API, or to validate email address deliverability.
Output
Returns a JSON object with the email address and domain, a deliverability_score (0–100 integer), a risk label (e.g. 'low', 'medium', 'high'), a list of MX records, boolean flags for is_disposable, is_role_account, and can_receive_mail, and a verification_level string indicating the depth of checks performed (e.g. 'domain_dns_no_mailbox_probe').
Example use cases
SaaS signup fraud screening
“Before we activate this new account, verify whether the email signup@tempmail.xyz is from a disposable domain and give me its deliverability score and risk level.”
B2B outreach list cleaning
“I have a lead email address contact@bigclient.com — can you check if it has valid MX records, a proper SPF/DMARC setup, and whether it's a role account before I add it to our sales sequence?”
Newsletter subscription validation
“Someone just subscribed to our newsletter with the email noreply@freewebsite.org — can you run a DNS-based check to see if it can actually receive mail and flag whether it's a role account?”
Technical details
Endpoint
POSThttps://x402.agentutility.ai/email-verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, privacy-safe email validation that goes beyond simple regex — specifically when you want DNS-level signals (MX, SPF, DMARC, DKIM) plus disposable-domain and role-account detection, without performing a live mailbox probe that could alert the recipient or get blocked by mail servers. Ideal for pre-send validation in email campaigns, onboarding flows, or lead qualification pipelines.
Side effects
- Invalid or malformed email address returns an error or low score
- Domain has no MX records — can_receive_mail returns false
- Disposable domain detected — is_disposable flag set to true
- DNS lookup timeouts for obscure or newly registered domains may degrade result accuracy
- DKIM check may return inconclusive if no common selectors are found and none are provided
