Deep Dive: Switching from Clean Email to Inbox Zero
Trade-offs, installation & data architecture
What you trade away
Inbox Zero’s free route demands Docker, OAuth infrastructure, and an AI key and supports a narrower mailbox set than Clean Email’s zero-admin multi-provider service.
How to deploy Inbox Zero
Use the hosted service or run the official CLI-assisted Docker deployment with Node.js, PostgreSQL, Redis, OAuth, and environment variables
What it takes to run
The free self-hosted path needs Docker, Node.js 24+, Google or Microsoft OAuth application setup, mail webhooks or Pub/Sub, a domain with TLS, and an AI API key
Where your data lives
Account, rule, and encrypted OAuth-token metadata live in PostgreSQL and Redis on the selected host; email content used for classification can be sent to the configured model provider
Why fork Inbox Zero instead of vibe-coding a Clean Email clone?
The visible inbox cleanup loop is buildable, but a credible replacement needs more than the first screen. Clean Email earns its keep through deliverability, security, integration, so expect a weekend or multi-day build and a narrower personal scope.
