I've already introduced this over on my agency's website, Digizu, however I'd like to introduce a new feature that we've just added. Oh, and did I mention it's free?
You can now embed any form or page from Digizu pages directly within your website. Simply create your desired form layout, and copy the embed code directly from the settings tab.
You can see an example of this in use on my contact page!
Oh, and because it simply injects the html form onto your website, you can style it however you want!
