Hi,
To insert tags using the html editor they must be added manually. Dynamic text tags can be found in the bottom of the design panel in the drag & drop editor.
If you are looking for tags used for articles, please add the articles in the drag & drop editor and inspect the HTML of the block. To do that, select the block, scroll down in the right-hand panel and click on the "Edit HTML" button.
Please note that certain tags may not work in the HTML editor, especially for add-ons. We strongly recommend getting familiar with the drag & drop editor, as it is the future of Acymailing.
