CSS Notifications question

Does Gravity Forms Notifications customization for emails limit us to only inline CSS or can we make declarations of CSS at the top of the notifications, if so; do we declare the CSS just with <style> </style> even without a <head> existing?

Hi Frank,

For the best compatibility with multiple email clients, you must use inline css. Not all email clients recognize or interpret style blocks. The support for external or embedded style sheets is spotty at best across different clients, so the best way to confirm is, honestly, just to test and see if it works for your different clients.

Please note that some email clients immediately spam or restrict any external links for obvious reasons.
