HTML tags stripped out

Hi,

I am trying out the free version before paying and wanted to see if I could use HTML tags in the editor, but they seem to get stripped out.

I created a notification as a test for “New Media Published”

Is there a solution to this? I have an email template with HTML tags, and CSS tags for styling, but when I paste it into the “Message Body” field, it strips all the tags out.

How can I use HTML for my templates and CSS styles
