It is possible to add a template within a template?
Problem
We have multiple email templates, which require some standard text in each of them. it is time-consuming to update every template, if we update the wording of this text.
Solution
What I would like to do is to have some standard terms conditions, in text ( not as an attachment), populated into the email template automatically. (the text is greater than what the snippet would allow)
With these terms conditions managed in single place with a template etc.
Apologies for missing that piece @Mart . Have you tried breaking your content down into multiple snippets? You mentioned Terms and Conditions - often those are in numbered paragraphs, perhaps you could use a handful of snippets with a paragraph or two each.
The other alternative would be to start from a clone, and edit the main content, leaving the T&C’s in place.
