[O] send org subtree as e-mail?

[Peter Salazar]

I frequently compose e-mails as subtrees of my org files. I'd like to be
able to e-mail the contents of these subtrees, maybe by first viewing the
subtree in an indirect buffer.

My org files look like this:

* e-mails
  ** note to person about blah
     To: per...@blah.com
     Subject: ADD people 7 times more likely to be creative
     --text follows this line--

     Dear Person,

     Blah blah blah.

     Best,
     Peter

I can open the subtree in an indirect buffer, but I can't e-mail the
contents as they appear because I get "Invalid header line."

If I delete the org-header, I can successfully send the e-mail. But then I
need to undelete the header afterward.

How can I send the contents of a subtree as an e-mail without first having
to delete the header?

Thanks,
Peter
