Unlike invitations, there's no need to include RSVP cards with your Save the Dates. Guests aren't expected to respond until they receive the invitation, although some may. DO add your wedding hashtag and wedding website.

Does save-the-date mean you're invited?

A save the date card doesn't necessarily mean that you're invited to the wedding - it simply means that you're on the proposed guest list. ... That said, couples don't just send save the date cards to anyone, so if you've got one it's a safe bet that you are going to be welcome at the wedding.

Does everyone who gets a save-the-date get an invitation?

The recipients.

Everyone on your "A" guest list-even your maid of honor who found out the second you booked the venue-should receive a save-the-date. (Due to budget and venue restrictions, you may have a "B" guest list-people you would love to have at your wedding but can't invite until regrets come in).
