Use succinct wording on save-the-date invitations. Include only the most basic information, such as the names of the people getting married and the date and the location of the wedding. Let guests know that a more detailed invitation is on the way.
The wording can reflect the couple's personalities and interests. There are no absolute rules about how to word a save-the-date. The function of a save-the-date is to give guests the information they need to plan travel and time off of work to attend the wedding, so as long as the wording includes the date and location, the save-the-date is a success. TheKnot.com, PurpleTrail.com and AmInvitations.com provide dozens of examples of save-the-date wording.
TheKnot.com suggests the standard wording for save-the-dates is, "Jack and Jill are getting married on July 5, 2015." Then list the location on the next line. Most save-the-dates conclude with the standard line, "Formal invitations to follow." For a less formal save-the-date, TheKnot.com suggests alternative wordings such as, "He proposed ... she said 'Yes!' Jack + Jill will tie the knot on July 5, 2015," or, "We're taking the plunge! Hope you'll be there to celebrate our flight. Jack & Jill say 'I Do' on July 5, 2015."
