MailSleuth is an extremely quick and efficient email OSINT (Open Source Intelligence) tool designed to check the presence of email addresses across various social media platforms and other web services. It supports single email checks, bulk processing from files, proxy usage for anonymity, and configurable concurrency for performance optimization.

This gem provides a model and an observer to log e-mail delivery.
