About

Sealch is an email verification service that runs the same live SMTP and catch-all check as ZeroBounce and NeverBounce — at a flat $0.35 per 1,000, roughly 10× cheaper. Upload a CSV or call the bulk API, and every address is checked in real time against the recipient's mail server (no email is ever sent). Results come back cleanly segmented into deliverable, risky, and invalid, with catch-all domains flagged honestly as "risky" instead of a false "valid." You're never charged for unknowns, and credits never expire. Built for outbound and email marketing teams who need a clean list before they send — without paying enterprise prices. Features include live SMTP verification, catch-all detection, disposable and role-based address filtering, bulk CSV processing, and a REST API. Start free with 200 verifications, no credit card required.
