This uses the dealer's existing "ANNOUNCE" MailChimp template exactly as-is (header, disclaimers, social links, unsubscribe footer) — only the vehicle listings below are generated fresh from your picks.
Check a vehicle to include it, then pick which of its photos to use (first photo is selected by default). The template shows one large hero photo plus up to 4 more in a 2x2 grid, so selecting 5 photos per car gives the fullest layout. Vehicles are added to the email in the order you check them.
