Planning a wedding involves making numerous detailed decisions and plans. Unfortunately, life happens and plans have to change on occasion. Perhaps a family or work emergency requires you to postpone your wedding date, or your venue suddenly goes out of business. Take action immediately if you have to change any wedding plans once you have spread the word about your big day, sent out your wedding invitations or committed to anything.
Secure another venue, vendor or wedding date, if applicable. If you're postponing the wedding indefinitely, notify your family, friends and potential guests.
Inform your wedding planner, officiant, bridal party and families of your changes right away if the changes affect them. Update your wedding website, if you have one, or call the people involved.
Send postcards to inform guests of venue changes, such as if your ceremony or reception location have changed. The postcards should have some wording that make them stand out from the invitations so your guests know it's important to pay attention to them. Let your guest know exactly what the change is, such as "We just wanted to inform you that the ceremony location has changed, but the reception location is the same" and list the details.
Call each of your guests, starting with those who live out of town, if you are changing your wedding date or canceling the wedding altogether. Enlist the help of your parents and bridal party if your guest list is overwhelmingly long.
Follow up your phone calls with new invitations, preferably with a different design, that list all the new details. Send new invitations that look different; they are more likely to draw attention.
