The address is not in this project: not in a form submission, a
document, a chat conversation or a sign-in of one of your apps, and the owner
did not confirm it. We only send to people your project already knows, never to
a bought or imported list. If the user really wants to mail this person, ask the
owner to confirm the address (allow_email_recipient in a chat where the owner
is signed in, or in the portal), then send again. This error also appears when the person
unsubscribed and the email is not transactional.
