After you've created your app to send to clients, it's time to send it out! This is incredibly similar to how you're used to sending client Galleries, but let's go over it together!
Sending out Mobile Apps
First, click on the "Galleries & Apps" button to view all of your currently active Galleries and Mobile Apps.
Identify which app you're wanting to send to your clients and select "Email". You'll be prompted to put in your client's email address and then write a message for them!
