GmailClass adds labels to the emails in your inbox. You configure what labels these should be, and how to categorize them.

Powered by Jev

Mark a label with a specific color to instantly know if they can be deleted or if they should be read. You usually already have an auto-trigger on certain emails you throw away instantly.

Watch a short video in which the setup and functionality gets explained. As well as how to set up the labels.

Install GmailClass in your browser, then open the extension to get started.
