How this service works
Validate and classify an email DOMAIN from public DNS: MX hosts + mail-provider, SPF and DMARC policy, plus disposable / free-webmail / role-account flags and a deliverability signal. No SMTP probing of individual mailboxes (privacy + ToS).
Output
Returns MX hosts and identified mail provider, SPF and DMARC policy details, boolean flags for disposable/free-webmail/role-account classification, and an overall deliverability signal for the domain — all sourced from public DNS without any SMTP mailbox probing.
Example use cases
Example prompt
“Can you check the email domain for john@tempmail.io — I want to know if it's a disposable address, whether SPF and DMARC are properly configured, and what mail provider is behind it?”
Technical details
Endpoint
GEThttps://webtools402.176-109-107-191.sslip.io/enrich/emailWhen to prefer
Use this endpoint when you need to validate or classify an email domain at the DNS layer without probing individual mailboxes — ideal for pre-send list hygiene, signup form validation, spam/disposable detection, or checking email authentication policy (SPF/DMARC). Prefer over full SMTP-probe services when privacy compliance and Terms-of-Service adherence are priorities.
Side effects
- Domain has no MX records — deliverability signal will be negative or unknown
- DNS lookup timeout or NXDOMAIN for non-existent domains
- SPF or DMARC records absent — flags returned as missing/none
- Invalid email or domain format in query parameter — likely 400 error
- Payment not provided or insufficient — 402 payment required
