Valid Email Checker
Valid Email Checker is a rapid and precise platform designed for email verification and list cleansing, catering to marketers, agencies, e-commerce businesses, and developers who aim to reduce bounce rates and safeguard their sender reputation. Each email address undergoes our proprietary 11-stage verification process, which includes checks for syntax, MX records, SMTP handshakes, mailbox probing, catch-all addresses, role accounts, disposable emails, spam traps, full mailboxes, and disabled accounts, ultimately providing a clear status along with a risk score ranging from 0 to 100 and an assessment of deliverability. We stand out by promising that if a verification result is marked as Unknown, we will automatically issue a refund for the credit without any hassle or hidden terms; unlike many other services, we don’t charge for such checks, and every refund is transparently recorded in your credit history. You can verify a single email in less than a second or conduct bulk verifications on entire lists using our resumable engine, which never times out. Additionally, our platform supports 17 native integrations with various ESPs and CRMs, including Mailchimp, Klaviyo, HubSpot, Brevo, and others, as well as compatibility with platforms like Make, n8n, and Integrately, or you can utilize our REST API for more tailored solutions. New users are welcomed with 150 free credits to get started on their verification needs.

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.
