Sealch
Sealch is an email verification tool that performs live SMTP and catch-all checks akin to services like ZeroBounce and NeverBounce, but at an impressive rate of just $0.35 per 1,000 verifications, making it nearly ten times less expensive. Users can easily upload a CSV file or utilize the bulk API, ensuring that each email address is verified in real-time against the corresponding mail server without sending any emails. The results are presented in a clear format, categorizing addresses into deliverable, risky, and invalid, while catch-all domains are accurately marked as "risky" rather than misleadingly labeled "valid." You won't incur charges for unknown addresses, and your credits remain valid indefinitely. Designed specifically for email marketing and outbound teams, Sealch ensures that you have a reliable list ready for campaigns without the burden of high enterprise costs. Additional features include live SMTP checks, detection of catch-all and disposable addresses, filtering of role-based email addresses, bulk CSV handling, and a REST API. You can kickstart your experience with 200 verifications at no cost and without the need for a credit card. This makes it an ideal choice for businesses looking to enhance their email outreach efficiency.
