How to reply to a customer complaint email

Updated November 12, 2026

Reply the same day if you can, and within one business day at most. Say sorry for the specific problem, say what you will do about it, and give a date. Do not argue or explain first. People forgive a mistake faster than a slow, defensive answer, and a clear next step ends most complaints.

Reply

Same day, one business day at most. An unanswered complaint feels like being ignored, and that is when customers post reviews or dispute the charge.

What your reply should say

1. Open with the specific problem in their words, so they know you read it.
2. Apologize once, plainly, without excuses or blame.
3. Say exactly what you will do to fix it, and by when.
4. Give them a direct way to reach you if the fix does not work.

Mistakes to avoid

• Starting with company policy before you have acknowledged the problem.
• Writing "we are sorry you feel that way". It sounds like you doubt them.
• Promising a fix without a date, then going quiet.
• Blaming a colleague, a courier or the customer in writing.
• Sending a long explanation when a short answer and a fix would do.

Questions people ask

Should I apologize if the customer is partly wrong?

Yes, for the part that is true, such as the frustration or the delay. You can apologize for their experience without accepting blame for something you did not do. Then state the facts calmly and offer what you can. Keep the apology specific, not a blanket "sorry for everything".

Is it okay to offer a refund right away?

If the complaint is clearly fair and the refund is small, yes. It often costs less than a long exchange. If the amount is large or the facts are unclear, say you are looking into it and give a date for your answer. Check your own refund policy first.
