Step #1: Go to your Promotions tab. Click to select the email newsletter you’d like to instead receive regularly in your Primary tab.
Step #2: Drag this email over to the Primary tab. This will let Gmail know that you don’t consider this newsletter to be promotional because you’ve asked to receive it.
Step #3: Gmail will ask if you would like to apply this setting to future messages. Click “Yes.” This will ensure that all future emails from this address will be placed in your main (Primary) inbox.
WHEW!!! That wasn’t too hard, was it?
And you’re done!
