Overview

What is EmailEngine?

EmailEngine is a self-hosted email gateway that exposes mail accounts via a unified REST API. It hides the complexity of email protocols and OAuth2 authentication: a single API allows you to read, search, send, and manage messages, regardless of whether the underlying account uses IMAP/SMTP, the Gmail API, or Microsoft Graph (Outlook / Microsoft 365).

Its key advantage is real-time webhook management: upon receiving a new email or when an account changes, EmailEngine notifies your application instantly. This allows you to build mailbox integrations — inbox synchronization in a SaaS, transforming emails into support tickets, automations — without directly handling IMAP/SMTP servers.

Technically, EmailEngine is a Node.js application that relies on Redis for its state storage (connected accounts, webhooks, processing queue). DINAO deploys the entire stack in containers, manages Redis, and includes its state in backups. Note: EmailEngine is commercially licensed software, not open source.

FAQ

You might be wondering…

Which email providers are supported?

Any standard IMAP/SMTP account, as well as Gmail (Gmail API) and Outlook / Microsoft 365 (Microsoft Graph), with managed OAuth2 authentication.

Do my emails pass through a third-party service?

No. With self-hosting, email data stays within your network, on our French servers. Nothing passes through an external service.

Is EmailEngine open source?

No. EmailEngine is self-hostable software under a commercial license (publisher subscription). DINAO installs and maintains it for you; license terms are to be specified in your quote.

What needs to be backed up?

The state of accounts and webhooks is stored in Redis. DINAO includes Redis in daily encrypted backups so you don't lose anything.

Who is EmailEngine for?

Developers and SaaS publishers who want to integrate mailboxes (inbox sync, support, automations) without coding the IMAP and OAuth2 mechanics.
