Sealch LLC Opiniones 

Escrito por la empresa

Sealch is an affordable email verification service built for cold email teams, agencies, and marketers who need clean, deliverable lists without paying enterprise prices. We verify email addresses with a real, live SMTP check — the same method used by ZeroBounce and NeverBounce — to confirm whether each mailbox actually exists before you send. Upload a list for bulk email verification, check a single address, or plug our email verification API straight into your signup forms and workflows. Every address is sorted into deliverable, risky (catch-all), or invalid, so you can clean your list, cut your bounce rate, and protect your sender reputation. Built-in catch-all detection, disposable-address filtering, and role-account flags give you accurate results you can trust — at 99.2% accuracy. Where Sealch stands apart is price and fairness. We run the exact same SMTP verification as the big-name tools at a fraction of the cost — from $0.35 per 1,000 verifications instead of the usual $8 — and we never charge you for "unknown" results. If a mail server blocks a check, that credit is refunded automatically. Credits never expire, your data is never sold, and all scan data is permanently deleted after 30 days. Sealch is operated by Sealch LLC, a registered company in Wyoming, USA — fast, accurate email list cleaning without the enterprise bill.Ver más
