## Description

MailValid is an email verification and list-cleaning service for teams and individuals who want to improve the quality of the addresses they use for outreach, marketing, recruiting, and customer signups. It offers 100 free credits, with paid verification starting at $0.00075 per email; purchased credits do not expire. Users can check a single address in the web app, upload CSV or TXT files for bulk cleaning, integrate verification through a REST API, or connect compatible AI agents through its MCP server.

MailValid checks email syntax, domain and MX records, and mailbox availability without sending a message. Results can flag invalid, disposable, role-based, free-provider, and catch-all addresses, helping users identify risky contacts and maintain cleaner lists. Bulk jobs support up to 10,000 addresses, with results available for download as CSV or JSON. The service also supports signup verification, CRM data hygiene, lead-list checks, and pre-send validation for cold email and recruiting campaigns. MailValid reports 95%+ accuracy, 99.9% uptime, and more than 10 million emails verified.
