When should I send rehearsal dinner invitations?
Invitations to the rehearsal dinner should be sent two weeks before the wedding. You should not mail them with the wedding invitation, because it is a separate event. Plus, you don’t want that invitation to compete with or upstage your wedding invitation – you want to give your guests time to absorb and get excited about the actual wedding by itself.
If the rehearsal dinner is less-formal, it is acceptable to use digital invitations or invite people via phone as well. This should also be done two weeks before the wedding.
