Version 1
Subject: Your order 30418 and our apology Dear Ms. Lopez, Your order 30418 arrived four days late, and that was our fault. We shipped it to an old address we had on file instead of the one you gave us at checkout. You were waiting for a parcel that should already have been with you, and you had to plan around our mistake. I am sorry. We have taken three steps. Your address is now updated in our system, we have refunded the shipping charge, and we have added a check before dispatch so the delivery address is confirmed against the order every time. If anything else about this order is not right, please reply to this email. Sincerely, Tom Becker Brightside Home

How to write an apology letter

A good apology letter says plainly what happened and owns it, says how it affected the reader, apologises once, and says what you are doing to put it right and stop it happening again. Keep it short and specific. Leave out excuses, blame and "if you were offended", and never promise anything you cannot deliver, such as a refund or a date nobody agreed.

  1. Choose who it is forA customer, a business client, your manager, a teacher or school, or someone close to you.
  2. Say what happenedThe facts in a sentence or two: what went wrong, when, and the order or project it concerns.
  3. Add what you are doing about itA refund, a fix, a new process. Leave it empty and the letter gets a [what you will do] slot, nothing invented.
  4. Pick the format and copy a versionEmail, formal letter or a short message. Fill any [square-bracket] slots and read it once.

Common mistakes

  • Apologising for feelings instead of actions: "I'm sorry you feel that way" is not an apology.
  • Long excuses or several apologies. One short reason, if it helps, and one sincere apology.
  • Promising a refund, a discount or a date you have not agreed to.
  • No next step. Say what you have done, or what happens now.

For businesses: fewer apologies start with faster answers

Many customer apologies follow a question nobody answered in time: where is my order, can I change it, how do I return it.

A LuckPanda support agent answers those questions on your website at any hour, from your own pages and documents. Topics you choose, such as complaints or refunds, always go to a person, and your team picks up the chat with the whole conversation in front of them.

A complaint handed to the team

You sent me the wrong colour and I needed it for Saturday.
I'm sorry, that is frustrating with a date coming up. A person on our team handles wrong items. I've passed your chat to them; could you share your order number so they can start right away?

For AI agents

Build it with your AI agent

Give an agent your site and it can create the chatbot, read your pages and test it through LuckPanda's API and MCP. It prepares the work; going live stays with you.

Use LuckPanda's MCP server (https://luckpanda.app/mcp) to build a website chatbot for me. Ask for my website address, call chatbot_create_from_website with it, wait until the pages are learned (chatbot_source_list), then run a few test questions with chatbot_test_message and show me the answers. Do not put it live: I will do that myself.

Instructions for AI agents

Needs a LuckPanda agent key (Settings › Developers) with the chatbot.manage grant. MCP endpoint: https://luckpanda.app/mcp (Streamable HTTP, bearer key).

  • chatbot_create_from_website { url }: creates a draft chatbot named after the site and starts reading it.
  • chatbot_source_list: pages learned, failed or skipped, with a reason for each.
  • chatbot_test_message: asks the bot a question as the owner. Test chats never email anyone.
  • Going live (chatbot_update with status live) is a person's action; an agent gets APPROVAL_REQUIRED.
