A high-performance email verification API running on the Cloudflare Global Edge Network. SmartFix validates adresses via live DNS/MX checks, flagging disposable "burner" emails (even those hiding behind subdomains), and suggesting real-time typo corrections. Built for developers who need low-latency validation for client-side forms and scalable parallel processing (up to 50 emails per request) for backend bulk cleaning.
Smart Conversion Logic :
SmartFix differentiates between fraudulent entries and accidental typo. If an address has a typo but the domain is technically active. The system provide a suspect_typo flag and a did_you_mean suggestion.
You Hold the Key: Since the domain is valid and not a disposable provider, we give you the flexibility to accept the lead or prompt the user for a real-time correction.
Hygiene vs. Conversion: You choose the balance. Whether you want a strict accepts or a frictionless signup, we provide the metadata to power your logic.
Stop Ghost Leads: Automatically reject disposable/burner emails (like Mailinator) that ruin your sender reputation and inflate your marketing costs.
Reliable Disposable Detection: SmartFix leverages a constantly synchronized and highly curated engine to identify temporary domains. By intercepting even the most recent burner providers, we ensure your lead quality remains uncompromised and your deliverability stays peak
Edge Performance: Powered by Cloudflare, processing requests at the server closest to your user for zero-lag integration.
B2B Intelligence: Instantly detect role-based accounts (info@, admin@)
High-Availability DNS: Using multi-provider DNS-over-HTTPS strategy to ensure MX lookups are performed with 99.9% reliability, even if one provider experiences downtime.
- Syntax Check: Fast-fail regex check to filter out malformed strings before they hit your database
- Typo Correction: Advanced algorithm to catch "fat-finger" errors (e.g.,
gmil.com→gmail.com). - MX Record Lookup: Real-time verification via DNS-over-HTTPS to ensure the domain can receive mail.
- Disposable & Burner Shield: Automatically blocks temporary email providers using a dynamically updated global list
Bi-Hourly Intelligence Sync: The system syncs with global databases every 2 hours to catch desposable domains and stealth burner domains. - Role Detection (B2B): Identifies generic accounts like
info@,admin@, orsales@for better lead qualification.. - Confidence Scoring: Returns a 0-100 score based on multiple signals, allowing you to set your own threshold for user registration.
- Freemail Identification: Detects if the address belongs to a major free provider (Gmail, Outlook, Yahoo, iCloud, etc.), helping you distinguish between personal and professional leads.
- Parallel Bulk Processing: Validate up to 50 email addresses in a single request. The system uses an asynchronous parallel engine, delivering results nearly as fast as a single validation
- Instant Single Validation : Ideal for client-side forms and real-time verification
- Subdomain Detection: Extracts the root domain from any subdomain to accurately catch and flag temporary/disposable emails.
