Anniversary Letter (Template & Samples)

An anniversary letter is a letter that is written to a person to congratulate them on a special day that marks a specific amount of time in a partnership. This can be written by a husband to his wife, from a wife to her husband, from a boyfriend to a girlfriend, a girlfriend to her boyfriend, or to celebrate the anniversary of a successful business.

In a romantic context, the letter affirms the strength of the relationship and the commitment that one partner has for the other. For a business anniversary, it serves as an acknowledgment of an important milestone for a business associate, partner, or business contact.

It’s always nice to receive a written acknowledgment from a partner about a successful relationship that has endured the test of time. Whether you’re writing an anniversary letter to your significant other or to a business partner, there are a few things to keep in mind to get your intended message across clearly and impactfully.

  • Honesty in the sentiments you include. Your partner knows if things have been easy or blissful so avoid making dishonest statements
  • Be kind. If there have been ups and downs, it’s okay to acknowledge them but end on a positive note. In every word that you choose, be kind.
  • Highlight the strengths. If you include ups and downs, place more emphasis on the legitimate strengths of your partner and your relationship. Point out times when he or she has excelled instead of shortcomings.
  • Speak from your heart. If there is something special that you want to tell your partner, now is the time to do so. Speak from your heart and tell him or her something that he or she will value for years to come.
  • Remind your partner of your past and look towards the future. Reflect on times from your past that are memorable for both of you. Then talk about your future together and your hopes as you enter into it together.

Sample Anniversary Letter

5th Anniversary Letter to Alex

My Dearest Alex,

We’ve been together as husband and wife for five years today. I wish that each day would have been filled with the joy and happiness that we felt in that first magical year of our marriage. Life happens to everyone, and circumstances outside of our control upset the perfect bliss we felt together. When hard times came, I saw what kind of man you truly are. The loss of our baby, the fire that consumed our home, and the scars that we bear as a result of that night changed our lives forever. Though grief has been a constant companion, you found a way to smile and to laugh again, and you helped me to know what it is to continue pushing forward in life. You make me smile and feel joy in the midst of the rest.

Although there have been hard times, you never wavered. I see your strength, and it has given me the backbone to start living life once again. I cherish every moment with you, both good times and bad, and I know that as long as we’re together, there isn’t anything that can break us down.

You are the love of my life. I marvel as you painstakingly assemble vintage cars and take a heap of rust and turn it into a masterpiece. We each have our own hobbies that give us time apart to think and to grow as individuals, but when we’re together, it’s as magical as the first day we met. Thank you for being my strength and for showing me that I can be strong and stand on my own two feet once again. I love the life that we have built together, and I look forward to whatever the future may bring.

Yours eternally,
