VeriMails is an email verification tool designed to identify invalid, risky, or outdated email addresses before they cause bounces. It performs live SMTP handshakes and catch-all detection to determine whether an address is deliverable, risky, or undeliverable. The service is available as a web interface for manual checks and bulk CSV uploads, as well as through a REST API for integration into external applications, CRMs, or workflow automation tools. Verification results are returned in sub-2 second response times via the API, and bulk uploads include real-time progress tracking. The tool offers an email finder feature that generates verified person-level email addresses from a first name, last name, and company domain. Pricing is based on a credits system with no subscriptions or expiration dates. Each verification costs $0.0019, and new accounts receive 100 free credits with no credit card required. Bulk processing supports CSV files of any size, and the platform does not require an account for basic single email verification or for uploading a list, though credits are tied to an account. Typical use cases include cleaning prospect lists before sales outreach, maintaining sender reputation by reducing bounce rates, and ensuring high deliverability for email campaigns. Regular verification helps prevent spam filter triggers caused by high bounce rates and improves engagement metrics by ensuring emails reach real inboxes. The service is aimed at operators, sales teams, and developers who need accurate, actionable email verification without long-term commitments.
