Bursting Email body coming in single line

Hi,

Am having formatting issue with bursting email body and is coming in single line.

Note: Email body is dynamic and am taking form fnd_messages

Initially I have the busting control file strucute as below and there were no issues and email body is coming as entered in the fnd_message.

<xapi:message id="${REQUEST_ID}" to="${CF_CONTACT_MAIL}"
attachment="true"  content-type="html/text"  subject="${CF_MAIL_SUB}">
${CF_MAIL_BODY}
</xapi:message>

But, later to incorporate hyperlink in email body have modified the control file as shown below.

<xapi:message id="${REQUEST_ID}" to="${CF_CONTACT_MAIL}"
