AP Remittance Advice email message wraps the value of the attributes.

I am new to workflow.

I am editing an existing custom message in a workflow.  It has attributes that are substituted with a pl/sql.  The problem I am having is that the attribute values are longer than 80 characters and contain spaces.  No matter what I do, when the message is sent, it is wrapped.  I would prefer that it not be wrapped.  Is their anyway to stop it from doing this?  The attribute value contains a newline at the end of it.  It does not wrap the text in the message, only the value in the attributes if they are to long.
