Here is an easy way to prioritize your inbox and provide some visual feedback for those emails that are most important. Stars!
Now I know most of us know about “starring” an item as important but did you that in your settings (go to the gear in the upper right hand corner, then settings) you can customize your stars.
Personally, I have selected 4 different colored icons so I can make items in my inbox. For instance, a blue exclamation is for things I need to respond to and a yellow star is an email I may need to do something with. This helps keep me a little more organized and hopefully you find it useful as well!
