2 open-source projects that already do this job. Free to use - not free to run, which is what the numbers on the right are for.

What you give up either way
- Mobile apps (iOS/Android) and Chrome extension
- Polished UI/UX and product polish (notifications, inbox switcher)
- Built-in anti-abuse and scale protections used by the hosted service
- Multi-domain/custom-domain management UI and high-volume email routing limits
- SLA, priority support, and historic analytics
An open-source project doing the core job proves a replacement is possible. It does not prove it matches OpenInbox.io, and it does not prove anyone has run it for a month. How we decide.
