Who should you send save the dates to, including out of town guests and evening guests?

Your save the date list should match your final guest list as closely as possible. That includes close family, friends, and anyone you know will be invited to the full day. Out of town guests definitely need save the dates, because they have to book travel and accommodation early. For evening guests, think carefully. If you are certain they will be invited to the evening reception, you can include them. But if your plans might change, it is safer to wait and send them an invitation later. Sending a save the date to someone who does not receive an invitation is awkward. Also consider your bridal party, parents, and anyone helping you plan, they may already know the date, but it is still nice to send them one. If you have a large family or a long list of friends, you can send save the dates to everyone on your initial list, then trim later if needed. Just be aware that some guests will assume the save the date is a firm invitation. So only send to people you are confident about.
