This add-on will add a toggle button to the footer of the Specials & Search page.

Once clicked, a text area will open below the button to show the source code of the product list.

The list is formatted as a table with inline styling to work for most email clients.
(Outook has a tendency to strip out your css leaving your mailer looking odd).

This product list is reponsive and will adjust to the size of the email clients window.
