For example, you own the domain name "example.com", and you set up an email forwarding service such as Forward Email or ImprovMX to relay all emails sent to "*@relay.example.com" to your Gmail account.

The script will label your emails according to a set of rules. For example:

- "[email protected]" will be labeled "hello" - "[email protected]" will be labeled "hello" and "world" - "[email protected]" will be labeled "hello/world" ("world" as a sublabel of "hello") - "[email protected]" will be labeled "hello/world" and "yo/wassup"
