<button type="reset"> in email clients

Works in 10 of 21. Not supported in Outlook Classic, Outlook iOS, Yahoo Mail and 5 more. Partial in Gmail iOS and Thunderbird. Untested in Superhuman.

Your reader in Outlook Classic sees the email without <button type="reset">, even if it looks right where you tested it.
