HTML Email - Button as a Form in an Email

Wondering if it is ok to have a form inside an HTML email. All i would be doing is having an image input submit to a paypal buy page. I would like it to go right to paypal without going to a marketing page f开发者_开发百科irst...

I would have the whole form that paypal requires for a button.

You'll need to make sure the Content-Type of the email is set to text/html and the recipient's email client will have to support HTML emails, other than that I should mostly be fine.

Most email clients do not support forms within them, this includes outlook 2007, ideally if you can have this as a link behind a image is better as then you will get more support across email clients.
