While directly embedding audio files in emails is technically challenging due to compatibility issues with various email clients, there are alternative methods to include audio:
Audio Links: Include a hyperlink that directs the user to an external page where they can listen to the audio file. Audio Previews: Offer short snippets and teasers of the audio content to entice recipients to click through to the full content. Audio Thumbnails: Use images with a play button that, when clicked, redirect to the audio content.
