In the discussion of email warning for too many, you mentioned 11. I was sending an email using 12 people in the TO: field, and the first one on the mail list did not get sent and errored out. It was stuck in the outbox. Sent email to the same account, and they were successful, did not get stuck in the outbox.

Since the send action is divorced from the message creation, at which point should the error be displayed?

[ChristophWurst]

For better UX I'd say when the message is added to the outbox
