Beth wants to organize her emails in a main category of “bills” and then put emails in that category but also in sub-categories such as electricity, internet, etc. She uses Gmail, and luckily there is a simple solution. Gmail lets you create sublabels for any label, which effectively puts the emails in those sublabels in two categories, making them easy to find. Here’s how it works.
1. First you need to create an initial label. To do this just head to your Gmail and click the Settings button (symbolized by a cog icon) in the upper right corner. In the drop-down menu select Settings. In the Settings page that appears, click the Labels link in at the top of the page. Scroll down to the Labels section and select Create a new label.
Click this to create a new label.
2. Once your label is created, you’ll see it in the far-left column of your main Gmail view. Hover your mouse over the label, and a down-arrow icon will appear. Clicking it reveals a new menu. Scroll down to the bottom, where you’ll see Add sublabel.
Click Add sublabel here and go to the next step.
3. Once you’ve clicked that option you’ll be able to add a new label. Next, click the option labeled, “Nest label under” and select the main label you want to put it under. You’re done!
Check the “Nest label under” box
