<audio> in email clients
Works in 4 of 21. Not supported in Gmail, Gmail Android, Gmail iOS and 14 more.
Your reader in Outlook Classic sees the email without <audio>, even if it looks right where you tested it.

What to do instead in Outlook Classic
Replace <audio> with a styled play-button image linking to the hosted audio. Include duration and episode title in the surrounding copy so recipients have context before clicking through.
There is no drop-in fix for <audio> in Outlook Classic. Design so the email still reads without it.

Caveats (3)
- 1. Outlook 365, Outlook (New), Outlook iOS, Outlook Android: The
<audio>element is supported, but the video can not play due to a strict Content Security Policy. - 2. Proton Mail: The
srcattribute is transformed intoproton-src. - 3. Fastmail: Not supported. The
<audio>element and all its content is removed.
Caveats as recorded by caniemail (MIT), one entry per wording.
How <audio> behaves
The <audio> element embeds audio content. Email client support is essentially nonexistent, every major client strips <audio> tags or ignores the embedded player. The standard email pattern is to link out to a hosted audio player on the web instead.
- All major clients strip <audio> elements entirely.
- AMP for Email provides limited audio support but is not yet broadly adopted.
- Linked-out audio players are the only reliable cross-client pattern.
