Stop disposable email signups
DisposableScan checks any email against millions of domains, enriched with DNS, MX and IP intelligence — so throwaway accounts never make it through.
Type any email or domain to get a full disposable report.
Built for speed and accuracy
The database is the single source of truth — fast, and right.
Blazing fast
Known domains return from the database in under 10ms and from Redis cache in under 5ms — no DNS round-trip.
DNS & IP intelligence
MX, PTR, SPF, DMARC, nameservers, ASN, hosting & geo for every new domain.
Developer-first API
JSON REST, JWT + API-key auth, usage stats and full lookup history.
Bulk & imports
Verify thousands per request and import 100k+ domains from TXT, CSV or XLSX with a live progress bar.
