Could you please let me know what could be quickest way to design email notification.
is this something which can be achieved using Nintex forms
If you are talking about the design of the email's body, I suggest you to design your email on any HTML tool editor.
Then paste the HTML designed on the workflow action, and finally add references to information (fields,variables,etc)
While you are testing your notifications consider that every email client has its own rendering engine and the format could differ.
Thank you Fernando for your answer.
