How to Write an Effective Complaint Letter

A useful complaint letter should focus on facts rather than insults or emotional language. The recipient should be able to understand the problem and determine what action is being requested.

  1. Identify yourself clearly. Include your name and appropriate contact details.
  2. Identify the recipient. Provide the organization and, where known, the relevant department or official.
  3. Explain what happened. Give specific and accurate details about the problem.
  4. Include important references. Account numbers, order numbers or other references can help the organization locate the relevant record.
  5. Explain the effect. State how the problem caused inconvenience, loss, delay or another significant consequence.
  6. Request a reasonable resolution. Clearly explain what you would like the recipient to do.
