Is it rude to send a save the date but no invite?

A save the date is a commitment. It tells someone to keep the date free, book travel, and arrange childcare or time off. If you send one and then do not follow up with an invitation, you leave the guest in a difficult position. They have planned around you, and then they are dropped without explanation.

Sometimes numbers change, venues shrink, or budgets tighten. If this happens, contact the person personally, not by group message. Apologise sincerely, explain briefly, and do not ask them to keep the date free for a future event. If you are worried about guest numbers, do not send save the dates at all. Wait until your guest list is final and send invitations only.

For a large wedding, it is kinder to send save the dates only to people you are certain you can invite. For a small wedding, skip save the dates entirely and send invitations earlier, about three to four months before. That way, no one is left wondering. If you do send save the dates, treat them as a firm promise. Your guests will thank you for the clarity.
