Important: If You Use Gmail
Google has split your inbox into three separate inboxes and created tabs across the top labeled Primary, Social, and Promotions.
Virtually all emails from bloggers, other websites, and people you subscribe to are lumped into the “Promotions” tab automatically… where you may not see them.
And unless you choose otherwise, much of the valuable content you’ve specifically asked to receive will also end up under the Promotions tab by default.
The good news is you can quickly and easily choose which emails go into which inbox tab.
Look at your Gmail account to see if the “tabbed” inboxes have been turned on (you’ll see the tabs across the top of your emails).
If so, here’s how to make sure you’re seeing the emails you’ve asked to see: Click on the Promotions inbox tab. Drag any emails from anyone you want to hear from and drop them onto the Primary tab.
If you want to totally turn off the tabbed inboxes (which I did, because I don’t want anyone else screening the emails I’ve asked to receive and I don’t want to keep having to check multiple tabs), just click on the Settings “gear” image at the upper right corner of your inbox and select “Settings.”
Click the “Inbox” tab and uncheck ALL of the categories except “Primary,” then save your changes.
