The first thing you should know when it comes to sending save the dates to your wedding is that whoever you send your save the dates to, is also invited to the wedding. So definitely finalise your guest list before any official correspondence is sent out about your big day!
Therefore, you need to be very careful who you send your save the date cards to as save the date cards are recognised as official correspondence about your wedding, and those who receive one, will expect a formal invitation with more details shared.
The only time where it has been understood and acceptable to NOT send a formal invitation after a save the date was sent, is in the times of COVID-19 postponements and downsizing of weddings due to local restrictions at the time.
Everyone you intend to invite to your wedding. The same guest list should be used again for the invitations.
If you are unsure on whether you should include a plus one option for a guest, then hold off until you are certain and when you send the invitations. Only include a plus one on the save the date card if you are absolutely certain that you want to extend one.
This will ensure it is crystal clear who is intended to be invited. If you don't include the guest names on the save the date card, it could be assumed by your guests that a partner is invited or the whole family. So be clear to add all names to the save the date card.
