Wording help

Our wedding date has changed, so I'm trying to make something to send out to let everybody know. It has been pushed back 2 weeks.

How should I word the card? I am drawing a blank here.

did the invitations go out already or just the save the dates?

Quoting Captain Obvious:" did the invitations go out already or just the save the dates?"

It's going to go in the envelope with the invitations. They are already ready to be sent out, but the invitations can't be re-made.
