A Wedding save the date postcard is a type of invitation that is sent to guests to inform them of an upcoming wedding and to "save the date" for the event. Unlike traditional Save the Date cards, which are typically sent in an envelope, save the date postcards are mailed without an envelope and can be less formal than traditional cards.

Save the date postcards typically include the names of the couple getting married, the date and location of the wedding, and a message inviting guests to save the date. They may also include an image or design that reflects the theme or style of the wedding. Some couples choose to include additional information on the postcard, such as travel or lodging details, or a website where guests can RSVP or get more information about the event.

Save the date postcards are a popular option for couples who want a simple and affordable way to announce their wedding date. Because they don't require an envelope or additional postage, they can be more cost-effective than traditional Save the Date cards. They also offer a fun and playful way to invite guests to the wedding and can be customized with a variety of designs and colors to match the couple's wedding theme.

The address and postage are typically placed directly on the postcard, and the postcard itself serves as the mailing envelope.

However, if you prefer to include an envelope with your Save the Date postcard, you can certainly do so. Some couples may choose to include an envelope for a more formal or traditional look, or if they want to add additional information or inserts, such as a map or directions to the wedding venue. If you do choose to include an envelope, be sure to choose an appropriately sized envelope that fits the postcard comfortably and provides enough protection during mailing to ensure that it arrives in good condition.
