Deluge/Plain Text/Rich Text Not Functioning

I am working to generate a "sendmail" script, but currently, anytime I create a line break it isn't converting over correctly and is showing a "\n" tag at each break in the rich text. No matter where I create the message (rich text/plain text/deluge), it is sticking the "\n" at each line break.

Here is an example:

When I enter the following deluge code: "Test <br> Test"

I end up with the following text in the Rich Text editor:

Test
\nTest
