Dear [recipient's name]:
To two of my favorite people, the happy couple, I want to extend my most heartfelt wishes for a happy anniversary. However, I realize that these wishes are arriving to you a few days later, so I want to apologize profusely for missing your special day. I hope it was wonderful and that you did something extra special to celebrate your relationship and all of the happy years you have enjoyed together.
I will definitely be there for the anniversary party that you and your family are hosting later this month, and I'm looking forward to seeing you then for the celebration. Here's to many more blessed years for the two of you. Again, happy anniversary, and like I said I'm so sorry that my wishes did not get to you on your special day.
Sincerely,
[Signature]
