How do I get the "new" Gmail email client?

Question

I use Google Gmail for a number of my email accounts, both company an personal.

I have noticed with surprise that some of my Gmail accounts have the new format, where my emails are grouped according to whether it is a Forum, Social or Promotion at the top tabs.

However, there is my one account that I use often that has not been migrated to this new version. I would like to use it as my email is very cluttered and confusing without it.

How do I upgrade to it?

Answer 1

I managed to find the solution and here is what I did:
Click on the right-hand wheel cog "Settings"
Then Click on "Configure Inbox"
After which you select the tabs that you want to appear at the top and click save and you're good to go!!!
