MailChannels provides a transactional email service for platforms, multi‑tenant applications, and hosting providers. It offers both SMTP relay and a robust RESTful Email API, along with inbound/outbound spam filtering, reputation management, and abuse isolation. The service is designed to protect sender reputation, detect compromised accounts, and give per‑sender controls, helping developers and hosting companies reliably deliver email without building their own infrastructure.
