Deployment modes
Choose where inbox2 runs
The same apps and the same inbox run four ways: free and local on your own devices, hosted by us, in your own cloud, or in your own building with our MX receiving the mail. You can start in one mode and move to another later without switching apps or leaving your data behind.

One product, four places to run it
