What is the SmartFix Email Edge API?
Email Validator API. Real-time, multi-layer email validation: syntax check, live MX record lookup, and disposable domain detection. Auto-normalized input. Fast, accurate, production-ready.
SmartFix Email Edge API is available on the JoJ API marketplace. Subscribe with a single JoJ API key, call it through one gateway, and pay from one wallet — no separate account or contract with the provider.
SmartFix Email Edge API endpoints
- POST
/validate$0.01 / callvalidate
The target email address for comprehensive validation. The system executes a multi-layer verification suite including syntax analysis, real-time MX record lookup, and cross-referencing against global disposable domain registries. Automatically trimmed and normalized.
- POST
/validate-bulk$0.01 / callvalidate-bulk
Parallel Bulk Processing: Validate up to 50 email addresses in a single POST request. The system uses an asynchronous parallel engine to check your entire list in the same time it takes to check a single address.
Frequently asked questions about SmartFix Email Edge API
Does this API perform a live SMTP handshake to verify individual mailboxes?
No. The API verifies that the domain is active and capable of receiving mail (via MX record checks, disposable domain detection and typo analysis), but it does not run a live SMTP handshake on the specific mailbox. This keeps responses ultra-fast and avoids false positives caused by greylisting or catch-all domains, while preventing IP blacklisting from deep verification.
How does it reduce bounce rates without an SMTP ping?
In real-world applications, mistyped domains and temporary addresses are the leading causes of email bounces. SmartFix Email Edge catches these at the source directly on the edge network: Syntax & Typo Detection: Identifies RFC format errors and instantly suggests domain corrections (e.g., @gmial.com → @gmail.com). DNS & MX Verification: Confirms in real time that the destination domain has active, valid mail servers. Anti-Abuse Filtering: Instantly flags temporary/disposable emails (e.g., Mailinator) and pinpoints generic role-based mailboxes (info@, admin@).
