How to enable multiple stars in Gmail


Gmail has a setting to enable multiple types of stars. Not "give this email 2 stars and this other email 1 star," but "give this email a gold star and this other email a blue star." YMMV as to whether this is helpful.


  1. Open up your Gmail settings. Under the "General" tab, find the "Stars" section and click on "4 stars".
