Hi,First of all, on the CMS part, you will need an endpoint where you'll
be able to select a email content and once selected, the CMS returns the
HTML back to the calling system, Campaign in our end, then in Campaign,
you can customise the Delivery form to add a button that would use the
new endpoint, once you've got the HTML you will save it in the field
content\html\source, you will also need to get the Text version of the
email that you would save in the field content/text/source....Certainly...
