Dear [recipient's name]:
Michelle and I are delighted to announce to you the exciting news about our upcoming wedding. Yes, after all these years, we will be getting married on May 15th. Of course, we want you to be there for our special day, and we will be providing you with all of the details in the near future.
Our wedding will likely be taking place somewhere here in town in the early evening on the 15th. It will be a relatively small, intimate event with just family members and close friends. We will be honored to host you in May and very much hope you can attend our wedding. Thank you for supporting our relationship over the years.
