Mailcatch.app

The product is an email and SMTP testing tool with a fake SMTP server that captures application emails in a sandbox inbox so teams can preview content, validate headers, and avoid sending test messages to real users. It is for developers and engineering teams building and testing transactional and application emails. It is delivered as a SaaS dashboard with per-account testing environments, project-based inboxes, and SMTP credentials compatible with any SMTP-enabled app or framework.
