And additionally, putting the recipients in the To: line sounds like a
really bad idea. Sharing PII without permission and stuff like that.

Make absolutely certain that all the SPF, DKIM and DMARC stuff is perfect.
Make sure that any links are to the corporate domain... always.

You want a neutral, paranoid 3rd party who is receiving the notice to be
absolutely convinced of its Bona Fides. Do not suppose that your abundance
of Sincerity excuses sloppiness. It won't. :(
