You're not quite finished with the correspondence yet I'm afraid - once you've tied the knot you'll need to reach out to your guests one last time and thank them for their presence, and any gifts they may have given you.
It's a lovely chance to reminisce about the day- lots of couples like to include a photograph or two from the wedding for their guests to keep.
It's good to get these out in a fairly timely manner, however your guests will understand if it takes a little time. We recommend that you aim to get them to your guests within three months of your wedding day.
