Setting up your email on your galaxy s6 edge can be done when you first turn your phone on. For whatever reason most people skip this part and choose to add it later. On the home screen of your galaxy s6 edge there will be an email icon simply click it. Next it will ask you to add your email and password, but make sure your connected to wifi and the internet or this next step wont work.
Once you have your email and password click next. It will take about 10 to 15 seconds, and ask you in the next prompt how often you want your galaxy s6 edge to check for incoming emails. I would set it to every five minutes just to be safe. Once you have that configured click done, and your phone will begin to load all your inbox emails. You can add more then one email account to your galaxy s6 edge, but I recommend you use 3 and don’t over due it.
