Start by adding an audio module to the body of your newsletter. If you’re unsure of how to do this, click here to see how to add modules.
After the module is in place, you can insert your audio by clicking the Add Audio button in the center of the audio module. Selecting Your Tracks in the left section of the pop up window allows you to choose an audio track from your linked Soundcloud account. (Make sure the audio track is marked as public, or it will not appear in the pop up window)
You can also add the URL of an audio track by selecting URL from the left menu and pasting the link to the track.
Hit the Go! button, and the audio will appear in place.
