Line feeds in mail content

I have tried everything I know of to get EOLs embedded in email message. &u0A, &u0D, text.FromUnicodeCodepoint(10). None of them seem to work. Is it possible to insert CR or LF into a mail message?

try
or \t

If HTML, try

Thanks Dave - that didn’t work (assuming I implemented it correctly).

Excellent Michel - that did it. Thanks.

And I just discovered that my code was specifying HTML. If I change that to plain text, &u0A, &u0D do actually work as well.
