Text type 'HTML' for the Channel 'Mail (Letter)'

Question

Dear Experts,
I'm unable to use the text type 'HTML' for the Channel 'Mail (Letter)' in mail forms, as a result of which fonts like arial and images like jpeg could not be used in mail forms created for letters.
Is there a way to use HTML type or to have more font options, insert JPEG images, tables etc in mail forms for letters?
Regards,
Kathir

In case, if you are using custom excel export functionality, you should use fileDownloadActionListener with in a button.
Here, you could specify the content type.
<af:commandButton text="Say Hello">
              <af:fileDownloadActionListener filename="hello_txt"
                                        contentType="text/plain; charset=utf-8"
                                        method="#{bean.sayHello}"/>
            </af:commandButton>For more details, check here:
