Ok, so this last information is something a bit different from the initial info provided ??
You are correct, CartBounty neither free, not paid version currently include an option to edit email templates using some WordPress style block editors. Instead we have tried to keep these templates as simple and easy to setup as possible.
And also no HTML tags are currently allowed in the email contents (they will be stripped out and it is done to make sure no errors are made inside these messages and the end-user receives a valid HTML email).
However if one feels comfortable and good with HTML, CartBounty has integrated templating system which allows you to directly edit HTML email and include custom HTML tags, styles etc. This option is intended for more advanced users / developers who feel the need to extend emails and take things just a bit further. Please take a look at our FAQ on using templates.
Let me know if you require further assistance or better open a support ticket.
Best wishes,
