Brides tend to favor the idea of sending out save-the-date cookies, but make sure that you include an additional slip of paper so the information does not get eaten up with the cookies.
Using bright and outstanding colors will make your save-the-date stand out among the rest of the mail. You want to create an everlasting impression in your guests’ minds so that they will never forget to attend your special event.
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.
On the other hand, if you are not sure whether a particular person or couple will be invited to the wedding, don’t send them a save-the-date card. And there is really no reason, and it’s a waste of your precious money, to buy and send these notices when all of your guests live relatively nearby or the wedding will not occur during a busy time of the year.
Some companies offer digital save the date cards as well. What this means is you have the card to use on your computer and you could send them out to any email address that you have. Since almost every household has a computer and an email address, this would be a good way to save money on postage stamps.
