As a consumer advocate who has reviewed, investigated and resolved thousands of problems during the past decade, I know there is a right way — and a wrong way — to write an effective complaint letter. The most effective way to get the outcome you’re hoping for is to keep your message cordial, concise and clear.  

To help you do that on your next problem-solving mission, I’ve created a free letter-writing template for you — and some sample letters so you can see this methodology in action.

You’re welcome.  😉

The structure of an effective complaint letter

Nearly all effective complaint letters follow a similar pattern: 

  • Cordial opening 
  • Concise explanation of the problem
  • Clear summary of your efforts to fix the fiasco
  • Conclusion that includes a reasonable resolution
  • Cordial closing

How does this work? Michelle’s sample complaint letters

You might be asking yourself, but how does this really work? How can you possibly squoosh all the things you need to say in a concise message? The good news is that you don’t have to. 

It is best to resist the urge to say everything you want to say in your complaint letter. Offload your angry thoughts and extraneous details to family and friends. The best way to get your problem solved is to strip emotion from your complaint.

The bottom line

The methodology I suggest to consumers for solving their problems is the same one I use when I take a case to mediation. If you follow my guidance and still hit a wall of resistance from a company, send your request for help to the Consumer Rescue team.
