EmailEngine is a self-hosted email automation system that provides a unified HTTP REST API, allowing developers to integrate sending, receiving, monitoring, and managing emails in their applications without directly handling complex email protocols (such as IMAP/SMTP).
EmailEngine uses a fixed annual license model, starting at USD 995 per year. This fee allows connections to an unlimited number of mailbox accounts and includes a 14-day free trial, making costs more predictable compared to per-mailbox monthly billing.
It broadly supports Gmail (via OAuth2 IMAP or the native Gmail API), Outlook/Microsoft 365 (OAuth2), and any general mailbox account that supports IMAP/SMTP.
