When you have created your Tag it can be added to the email HTML. The Tag is added to HTML in the normal way static images and links are used.
For example, here is the HTML code for the Kickdynamic example email with placeholders.
This applies to all Kickdynamic Tags.
To then see the Tag working you can save the HTML and open it in a browser. The Tag will work as normal when viewed in a web browser. To see what it looks like in the inbox then send a test as normal.
Once you have generated a Tag, it will not change. For example, if you create a rule and then decide to change the images in the rule, upon saving the changes, the Tag will remain the same. All changes will automatically pull through. You only need to add the Tag to the HTML once.
