In reference to Litmus, the table below shows which email clients support, somewhat support, or don't support forms:

Email Client	Forms supported?	Notes
Apple Mail	Yes	“GET” works as expected. “POST” opens up a landing page with a form instead of submitting from the email
iPhone Mail App	Somewhat	“GET” works as expected. “POST” does not submit.
Gmail Desktop Webmail	Yes	Submits with a popup alert.
Gmail (iOS)	Somewhat	Does not submit in iOS GANGA. “POST” input is also disabled.
Gmail Android	Somewhat	Only “GET” works, but opens up a landing page with a form instead of submitting from the email. With “POST”, the form visually appears, but does not allow user input.
Gmail Mobile Webmail	Yes
Outlook on Windows	No
Windows 10 Mail	No
Outlook MacOS	No	The form visually appears and allows user input on Microsoft email addresses, but does not allow submission.
Outlook.com	No	Submits only when an email is opened in its own window, rather than submitting from inbox view. Upon submission, input attributes are prefixed with “x_” so it can cause issues with collecting data. Would recommend hiding for this client.
Outlook iOS	Yes
Outlook Android	Somewhat	The form shows visually, but the keyboard doesn’t appear to allow users to input information so users would have to copy and paste text to input. Would recommend hiding for this client when a keyboard input is used but allow forms if using other inputs.
Yahoo! Desktop Webmail	Yes	Submits with a popup alert.
Yahoo! iOS	No	The form visually appears and allows user input, but does not allow submission.
Yahoo! Android	Somewhat	The form shows visually, but the keyboard doesn’t appear to allow users to input.
AOL Desktop Webmail	Yes
AOL iOS	No	The form visually appears and allows user input, but does not allow submission.
AOL Android	Yes
Samsung Mail App	Somewhat	The form shows visually, but the keyboard doesn’t appear to allow users to input information. Would recommend hiding for this client when a keyboard input is used but allow forms if using other inputs.
