On the subscrbe form (generated from the campaign monitor wizard) is it possible to change the submit button into an href tag instead so I am able to style it using CSS.
Hi shopkiwi, absolutely - swapping out a submit button for a href tag is documented here. The easiest method is:
<input type="image" name="your_image_name" src="your_image_url.png" />
Let us know how you go :)
