Your wedding is a very special day, and we understand that you may need to cancel your plans for any number of reasons. We want to make the process as easy as possible for you. So here is a wedding cancellation letter you should send everyone and let them know about the change of plans for your wedding.
Dear {Name},
It is with great sadness that we must inform you that, due to unforeseen circumstances, our wedding has been canceled. We apologize for any inconvenience this may have caused and hope that you can still join us for a celebratory dinner on the new date. Thank you for your understanding.
Sincerely,
Bride and Groom
