How do I re-link my email accounts together and change the notification alerts on my s7?

[AC Question]

After I did the "Android app update" in April of 2017 on my Galaxy s7, I found out that I didn't have all my email accounts together to change or view like they were before the app update and that I can't find a way to change the notification alerts on them.

Question is how do I re-link my email accounts and how do I change the notifications now?

Personally I can't stand the update and wish I never did it. The app icons that were changed look like a 3 year old did them.

Welcome to Android Central! What do you mean that you don't have all of your email accounts together to change or view? Are you talking about the stock Email app?
