Overview

MailVeri is a bulk email verification platform designed to clean mailing lists and improve deliverability. It processes up to 1 million emails per file using deep SMTP validation, catch-all detection, disposable email filtering, and role-based account identification.

The platform offers both bulk file upload and real-time REST API verification for integration with signup forms and lead capture systems.
