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.
Save the date cards are simple cards that give limited information. You can announce your engagement and announce the date of your wedding. It doesn’t have to list the location unless it’s going to be out of town for part or all of your guests. There are a couple of options you have when you use save the date cards. You can have postcards printed and spend less on postage or you can create a card to insert in an envelope.
Printing your names and wedding date on fridge magnets is an always popular way to inform friends and relatives of your wedding.
Stop to think for a moment: You have painstakingly put together your wedding event, and done all you could to make this as perfect as you wished; but you take a look around your guests and realized that only half of them were able to make it to your wedding. You obviously missed out your wedding save-the-date cards to ensure your guests kept themselves available on this special day of yours.
Do include photos that are relevant to your wedding; and use colors that relate to your wedding. For example, if your wedding venue is to be decorated with white and pink decorations, then use the same color theme for your cards as well.
