How this service works
Verify an email address before you send: syntax + MX + disposable/role/free-provider detection in one call, boolean-first (deliverable, safe_to_send) with a machine-readable reason. DNS-level check only — does not confirm the individual mailbox exists (no SMTP probe). For a scored trust report instead of a yes/no gate, see /email-intel/analyze.
Output
A JSON object containing: the normalized email and domain, a result string (deliverable/risky/undeliverable), boolean flags for deliverable, safe_to_send, format_valid, mx_found, disposable, role_based, free_provider, and smtp_checked, a list of MX records found, a list of risk_flags describing issues, and a human-readable reason code summarizing the verdict.
Example use cases
Block disposable emails at signup
“Before we create this account for the email address temp-user@mailinator.com, check if it's a disposable or throwaway address — I only want to allow real, deliverable emails.”
Validate leads before CRM import
“I have a new lead with the email contact@acmecorp.io — can you verify whether the domain actually has MX records and whether it's safe to send a sales email to that address?”
Flag role-based addresses in mailing list
“Check whether newsletters@bigcompany.com is a role-based email address like a generic inbox, and whether it's actually deliverable, so I can decide if I should include it in my campaign.”
Technical details
Endpoint
GEThttps://netintel.dev/email/verifyWhen to prefer
Use this endpoint when you need a fast, low-cost boolean gate (deliverable / safe_to_send) on an email address before sending, importing into a CRM, or creating an account — especially when you need disposable, role-based, and free-provider classification alongside MX validation. Prefer this over /email-intel/analyze when you need a simple yes/no decision rather than a scored trust report. Note that this performs DNS-level checks only and does not SMTP-probe the individual mailbox.
Side effects
- Invalid or malformed email address returns format_valid: false with reason indicating syntax error
- Domain has no MX records — mx_found: false, result: undeliverable
- Address is on a known disposable provider list — disposable: true, result: risky or undeliverable
- Rate limiting or quota exceeded returns HTTP 429
- Domain DNS lookup timeout may cause delayed or failed MX resolution
- Individual mailbox existence is not confirmed — smtp_checked is always false; a deliverable result does not guarantee the specific mailbox accepts mail
