To save yourself time with licking the envelopes, you might consider stickers. You can purchase round stickers with your last initial or a rose or heart. These can be found at the stationery store or where you are purchasing your invitations. Another option is to purchase glue sticks to seal the envelopes.
What you should do – Since this will be your first written contact with most of your guests, it’s important that they make a good first impression. Make sure that you spell each guest’s name correctly. If you are unsure about the spelling of someone’s name, look it up or contact someone reliable.
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.
