Apology Letter Template: Examples for Business, Work & Personal
A bad apology can do more damage than the original mistake. "I'm sorry you feel that way" blames the other person. "I'm sorry, but…" cancels everything before it. A good apology names what went wrong, owns it, fixes it, and shows it will not happen again.
That is all an apology letter has to do. Each template below comes in two versions — a print letter and a short email. Copy one, fill in the brackets, and send it.
What Makes an Apology Letter Work?
A sincere apology has four parts. Miss one and the letter feels hollow.
1. Acknowledge what happened. Name the specific mistake. "I am sorry we sent the wrong order" is an apology; "sorry for any inconvenience" is a shrug.
2. Take responsibility. Own your part without excuses. "I missed the deadline" works; blaming traffic and your computer does not.
3. Fix it. Say what you have done to put it right — a refund, a replacement, a new date. No fix, no real apology.
4. Prevent a repeat. One sentence about what will change stops the reader wondering if it will happen again.
Keep it short — under 200 words personal, under 250 business. Long apologies sound like self-defence.
How to Use These Templates
Replace everything in [square brackets] with your own details and delete any sentence that does not fit. Send it soon: a fast, honest apology beats a perfect one that arrives a week late.

Business vs Personal Apology: Tone Comparison
The four parts stay the same everywhere — only the tone changes.
| Business apology | Personal apology | |
|---|---|---|
| Opening | "I am writing to apologise for…" | "I am really sorry for…" |
| Language | Formal, plain, no slang | Warm, natural, your own words |
| Responsibility | "I take full responsibility" | "That is on me" |
| The fix | Refund, replacement, new date | Make it up to them |
| Prevention | A process change | A personal commitment |
| Closing | "Sincerely," + title | First name only |
| Length | 150–250 words | 100–200 words |
Sounding cold is the business mistake; sounding formal is the personal one. Match the tone to the relationship.
What NOT to Say in an Apology Letter
Some phrases undo the apology in the same sentence.
| Don't say | Say instead | Why it matters |
|---|---|---|
| "I'm sorry you feel that way" | "I'm sorry I did that" | Blames their feelings |
| "I'm sorry, but…" | "I'm sorry. What happened was…" | "But" cancels it |
| "Mistakes were made" | "I made a mistake" | Hides responsibility |
| "It wasn't that bad" | "I understand it upset you" | Denies their feelings |
| "If I offended you" | "I offended you, and I'm sorry" | Sounds hypothetical |
| "Sorry for any inconvenience" | "Sorry we sent the wrong order" | Sounds like a form letter |
| "Let's just move on" | "I'd like to put this right" | Denies them their say |
For business apologies, do not admit legal fault in writing for anything that could become a claim, such as an injury. Describe the fix and let a lawyer review the wording first.
Quick Tips Before You Send
- Send it promptly — apologies lose power every day.
- Keep it short. Past one page, you are probably defending yourself.
- Name the mistake once. Repeating it sounds like arguing with yourself.
- Fill in the brackets with real details.
- Check the name and the facts. An apology with the wrong name is worse than no apology at all.
Frequently Asked Questions
How long should an apology letter be? Short. A personal apology works at 100–200 words and a business apology at 150–250 words. Say what happened, own it, explain the fix, and stop.
Should I apologise by letter or by email? Use a letter for formal situations — a valued customer or a serious workplace error. Use email when speed matters, such as a late delivery.
What is the best opening line for an apology letter? Name the mistake directly: "I am sorry we sent the wrong item in your order." A direct opening shows you are not hiding behind vague language.
Can I use the same apology template for business and personal situations? The structure is the same — acknowledge, take responsibility, fix, prevent — but the tone should change. Business apologies are formal; personal ones are warmer.
What should I do if the other person does not accept my apology? Do not argue or send a second, longer apology. Thank them for hearing you out, repeat the fix briefly, and give them time. Pushing them will only make it worse.
