Tips to write an apology letter

Let us look at some tips to write a professional apology letter.

  1. Ask for forgiveness
    Cartoonist Lynn Johnston said that an apology is the superglue of life. It can repair just about anything. A sincere 'I am sorry' works like a charm. Seeking forgiveness can send across a clear message that you are sincerely sorry. However, avoid melodrama. 😜

  2. Accept your mistake
    It is important to own the mistake to show your sincerity. It can be a little difficult in some situations. However, it is the essence of a genuine apology.

  3. State what happened
    Sometimes it seems a redundant thing to do, yet it is very important. It ensures the wronged person that he/she was heard properly and that you are aware of the whole situation. Describing what happened also reiterates your stand on the whole situation. However, avoid being defensive and let the person know that you are genuinely concerned.

  4. Provide solution
    Providing a well-thought-out plan of action to resolve the issue is important. It calms down the wronged person, and he/she feels that you actually worked towards providing a solution for the problem.

  5. Provide assurance
    To maintain a healthy professional relationship, it is important to provide assurance that similar mistakes will not be repeated again. Describe the steps taken by you to avoid similar situations in the future. Also, state if similar situations arise, how you intend to solve them in a more effective manner.
