I installed "Add to All" v1.0.4 and added some content (below) to the Any other HTML (no PHP) to add to wp_head: section:
<meta name="com.silverpop.brandeddomains" ... />
Note: Part of the code has been cut out and replaced with "...". Searching on "silverpop" should find this though.
This code appears in the HTML for all the site's pages EXCEPT for the main page (home page). The URL for the site is http://test.ipc-global.com.
