Can you try something simple?
this is a<br/>test
Then export it in arx format and you shouldn't have any "\r\n".
I tried attaching a simple header template and it brought back funny characters,
I do not exactly remember how, but I did this some years ago without a problem.
I did not have HTML-data in my fields, I just wanted to send a HTML email with text from various fields.
I just created a .html file with #$$FieldName$$# in it I think...
I would suggest reading the Email Engine docs for details.

if you are using cusom filter to send email notification try below steps:
1. create simple html email template.
2. Mention that email template in Filters Notify actions Header Template.
3. Notify Text should be <html>text</html>
this should work....
