It's important for brides and grooms who are planning their wedding to send save the dates before sending the invitations. While it isn't a requirement, it is a courtesy to extend to your guests that will help them make travel arrangements so that they'll be able to attend your special day. Here is what you need to know about these cards.

Save the date cards are appropriate for every marriage ceremony, but there are some that they are more important for. If you are having a destination wedding, it is especially vital. Since these are often at places that attract a lot of tourists such as popular beaches, a heads up will give your guests time to save money and make early bookings and travel arrangements. If you have several out of town guests coming to your wedding, letting them know early on with a card is also advisable.

These should be sent as early as possible. It's good to send these out between six months (for local ceremonies) to eight months (for destinations that require travel) before your wedding. They go out a few months before you mail the formal invitations. Don't make the mistake of mailing them too early, as they will likely be forgotten by your guests.

Everyone who will be invited to your wedding should receive a save the date invitation. This means that you will have to decide on your guest list early on. Once someone receives a card, they must also receive a formal invitation. Etiquette dictates that everyone, even members of your wedding party, should receive one.

Be specific about who is invited. If you are having no kids at the ceremony, the parents will need ample time to make arrangements. List all of your guests by name on the envelope. This will help avoid an awkward situation later on.

Save the dates don't have to be as formal as your wedding invitations. They can be cards, postcards, or even magnets. Magnets are popular because they can be stuck on the fridge to remind your guests not to schedule any other activities on that day. Postcards tend to be cheaper, and can be a blessing for a couple who wants to save money for the actual ceremony and reception.

While save the dates aren't a requirement for a wedding, they are appreciated by guests. More people will be able to attend your ceremony and this advanced notice will make everything go more smoothly.
