A claim letter(also called a claim message) is a type of apersuasive letter identifying a problem with a product or service, sent by a customer to an agency or business. It may also be referred to as a letter of complaint.
When writing a claim message, you should focus on the most important facts. No unnecessary details, like a blow-by-blow chronology, are needed. You should include the reason for writing, what went wrong and what you'd like to happen. An effective claim message is written in a formal style, as anger and emotion are not an effective method of persuasion.
