You should send save-the-date cards to all of your intended guests when either of these circumstances fit your situation. Even friends and family members who you already know will attend should be sent a card.
Rules & Etiquette – Again, few rules apply. The only information you must include is your names and wedding date, although I suggest including location information as well so wedding guests can begin their travel plans. Aim to send save-the-date cards soon after you secure your date and venue, or about 4-6 months prior to your wedding. Remember, everyone who receives a save-the-date also receives an invitation, so have your guest list finalized prior to sending them. You can, however, always add guests later (there is no rule that says everyone must receive a save-the-date card). Although formal replies are not required, you can get preliminary attendance estimates through word-of-mouth.
Preparing family and friends for your wedding is a kind and thoughtful gesture. There are many different ways to create save the date cards, some of these ideas can be a bit pricey, while others are inexpensive, but these cards are a great way to announce your wedding plans to your guests ahead of time.
Save the date cards is the best way to announce your wedding plans to family and friends. You want to make sure that everyone you invite has plenty of time to plan for the event. It doesn’t matter if your wedding will be local or if they will need to travel, they need to be prepared. Save the date cards help everyone to do just that. You don’t want to send them out too early, but at the same time if you are going to use save the date cards, you need to send them out soon enough for them to do any good. It’s recommended that you send them out about six months before your planned wedding day.
Your save-the-date can take any size or form. If you decide on mailing cards out, then your cards can be the size of a postcard, or even smaller. Make sure the size does not cramp the wordings together.
