A branded email to every subscriber on a mailing list is sent as one campaign again, including after you look at the names on the list. Removing someone, or adding an extra person, still sends one copy each.
The campaign To line uses each subscriber's first and last name from their contact record. Reply-to is a real mailbox, so it no longer shows as a placeholder. Compact composer notices keep even spacing around the dash, and a long line wraps under the title. Title-only progress notices no longer trail a dash, and the privacy notice clears once the campaign has gone. If a send can no longer be tracked, the composer shows that once, with Save draft and refresh.
