Keep track w/o memory hogging

Kiwi for Gmail lets me keep track of my 6 Gmail accounts without consuming as much RAM as 6 tabs open in a browser. Clicking on links in emails opens a new browser tab as easily as it does within your browser. At first, I thought the price was too much, but it works well, I like that I can completely close the browser and still have access to email, and freeing up the extra memory makes the price worth it in my opinion.
