How can I Have Separate Alerts for Email and SMS?

I am using a Samsung Galaxy S4 running Android 4.2.2. Currently both SMS and Email notifications have the same sound. Before I was on this phone I was on an iPhone and this was easy to change. I cannot find a way to distinguish between alerts. In browsing this site for an answer I came across this question which had this answer: > You can customize the Notification settings for both Gmail and Messaging in each of the apps separately. > > In Gmail press menu and go to More->Settings and look at the Notification settings section. > >In Messaging press menu then Settings and look at the Notification settings section. I assume this answer is out-of-date because it doesn't work on the Galaxy S4. I am using the Stock Gmail App for email and I use GO SMS PRO for messaging. How do I change to separate alerts?
