Embed as HTML: Copy and paste the code into your website's content editor. By default, the form will fill the width of the container it's in. You can also make any inline styling changes you want. Embed as Iframe: This option lets you have the entire opt-in form within it's own frame. You can edit the max container width and height from within your form settings. Hosted: Use a URL that is hosted by Clearstream. Simply copy and paste the URL. This is useful if you want to point people to your form from 3rd party websites, like social media.
