How this service works
Email Address Validation (syntax, MX, disposable, role, typos). Email address validation before you send: syntax, whether the domain exists and accepts mail (MX, null-MX), disposable/throwaway provider (8,900+ domains), role address, free provider and typo suggestions (gmial.com -> gmail.com), with a deliverable / risky / undeliverable verdict. No mail is sent.
Output
A JSON object containing the submitted email, a boolean valid_syntax field, a verdict string (e.g. 'valid', 'invalid', 'risky'), and a reasons array listing specific issues found such as typos, disposable domain, missing MX records, or role-based address detection.
Example use cases
CRM lead email hygiene
“Before we import these leads into Salesforce, check if 'sales.lead@tempmail.com' is a legitimate email or a disposable throwaway — I need to know the verdict and why.”
User signup validation
“A new user just registered with the email 'contact@goggle.com' — can you validate it and tell me if there are any typos or if it's a role-based address I should flag?”
Marketing list deliverability check
“I want to verify 'info@acmecorp.io' before we add it to our email campaign — check if it's a role address, if the domain has valid MX records, and give me an overall verdict.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/email/validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, fast, multi-factor email validation that covers syntax, DNS/MX checks, disposable domain detection, role-address flagging, and typo correction in a single call. Ideal for pre-registration checks, CRM hygiene, and marketing list filtering where you want actionable verdicts with explanatory reasons rather than a binary pass/fail.
Side effects
- Missing or empty email query parameter returns an error
- Malformed email string may return invalid_syntax with no MX check
- Disposable domain list may not cover all throwaway providers
- MX lookup may time out for slow DNS responses
- Non-existent TLDs or domains return invalid verdict
