What is EmailEngine?
EmailEngine is a self-hosted email automation platform designed for developers and businesses seeking to integrate email functionality into their applications. It provides a unified REST API that connects seamlessly with various email protocols and services, including IMAP, SMTP, Gmail API, and Microsoft Graph API. This eliminates the complexity of dealing with multiple RFC specifications and email provider APIs, allowing developers to focus on building core features.
The platform offers real-time notifications via webhooks, OAuth2 integration for Gmail and Outlook, and features like hosted authentication and low-code custom integrations. EmailEngine ensures high deliverability by using the user's own email servers for sending emails and includes monitoring capabilities with Prometheus metrics. As a self-hosted solution, it keeps all data within the user's network, addressing data compliance concerns.

FAQs
-
What are the system requirements for running EmailEngine?
EmailEngine requires Redis as its caching database. A reasonably recent version of Redis is needed, and low latency between Redis and EmailEngine is recommended for optimal performance. -
Can I run multiple EmailEngine instances with a shared Redis database?
Currently, running multiple EmailEngine instances with a shared Redis database is not supported. Horizontal scaling is on the development roadmap, but no estimated time of arrival is available. -
How does EmailEngine handle data compliance?
As a self-hosted solution, EmailEngine does not send or store data outside the user's network. It retains minimal metadata for syncing and caching, but not email contents, ensuring data stays securely within the network.
