To use the native G Suite mail, contacts, and calendar apps on your Android, you need to add and then sign in to your new G Suite account. You only have to do this once:

Navigate to your Settings Gear.

From there, select Accounts > Add account (bottom of screen), then choose Google to add your G Suite account.

Next you'll be prompted to log in with your @willowcreek.org credentials.

Now that you've completed your log in, find and open your Gmail app. (Note: to download additional google apps, check out your app store)

From here, you can easily switch between your Google accounts using the ☰ in the upper left corner. From here you can

• Access your inbox
• Access labels and other mail
• Switch between Google Accounts
• Send and reply to mail
