Apology Letter For Mistake – 5+ Samples & Formats

An apology letter for a mistake is written to seek forgiveness after doing wrong to another party. When you find out you have made a mistake, be it in your business, work or home, besides a verbal apology, consider writing a letter to apologize for the mistake. Apologizing doesn’t make you weak but rather strong. An apology defeats your ego and makes you a better person.

Writing this letter can be tasking; you can struggle to get the best words to say sorry. In such a case you can rely on a sample or template.

What to include in an apology letter for mistake

  • Briefly explain what happened: When writing the letter, include your account of what occurred and why you feel the other person was hurt. At this moment avoid blame games; only address your role in the act.
  • Acknowledge the mistake: The best way to pass an apology is by owning the mistake. If you turn to blame others, you might make matters worse and fail to get a solution to the problem.
  • Seek forgiveness: Once you have owned the mistake, ask for forgiveness. Though you have wrong the other party, asking for forgiveness is a way of inviting them to find a solution to the problem.
  • Speak directly to the wronged person(s): Write the apology letter as if you are talking to the individual. By this act, you are making the letter personal. At the same time, your apology is focused, and chances of forgiveness are high.
  • Provide a solution: Besides seeking forgiveness, offer a solution to the problem. For example, if you erroneously sent few goods to a client, offer to top up the difference.

Sample apology letter/email for mistake


Mr. Bill McCarthy

57, Alvin Street


Date: 3rd March 2022

Subject: Apology for late delivery

Dear Mr. McCarthy,

I write this letter to offer heartfelt apologies for the late delivery of your order 12/2022 that was to be delivered to your premise on 02/01/2022. The order arrived three days later.

We are deeply apologetic for inconveniences caused to your business and customers. The lorry that was to deliver the parcel broke-down midway in the journey. Unfortunately, we did not have a standby vehicle on that day to take over the deliveries.

We sent another lorry the following day; thus, the parcel arrived three days later. Late deliveries hardly occur in our company since we always have a stand by lorry for emergencies but unfortunately, all Lorries were engaged, and the extra lorry was in the garage for servicing.

Once more accept our apologies; we are confident that this will not happen in the future.
