QUICK Guide to Marking
The Real Authority 
as a safe sender in Gmail. 

You will have to do this on your computer. Open Gmail. In the upper-right corner, select the Settings (gear) icon. From the menu, choose Settings.

Select Filters and Blocked Addresses at the top.

Select Create a new filter. If you already have many filters, you'll have to scroll down to find this link.

To allow every email address from The Real Authority, type just that domain name, like @therealauthority.com.

At the bottom of the dialog box, select Create filter.

On the next screen, tell Gmail what to do with the domain you just indicated. To do so, select Never send it to Spam. To finish the process, select Create filter. That's it!
