In my email account how do I create a group contact?

I have just started with AT%26amp;T, switched from Comcast, had a way to add a group of people so when I needed to contact several people I was able to do so by inserting group into BCC

In my email account how do I create a group contact?
Click on Contacts ... then click on Add Category ... name a new Category for example "Friends".





Then click on EDIT for each contact one at a time and specify a category he belongs to.





Click "Save and Add Another" or "Save".
