Can I use forms in my emails?
Email clients consider email forms to be a security risk. While some email clients simply warn you of potential danger, others outright disable the forms. So if your client wants to send out a form, they should know that most of their recipients will never be able to use it. And for those who can, they'll think twice about submitting data when they see a warning from their email client.
