The Postal Service’s complaint processing office will send you a letter to acknowledge that your complaint was received. You also will receive a separate letter telling you if the claim or claims in your complaint were accepted for investigation. If your entire complaint is not accepted, you will receive a letter explaining the reasons for the dismissal of your complaint and outlining your appeal rights should you disagree. (See Appealing the Decision or Filing a Civil Action)
If the Postal Service believes that some but not all of the claims in your complaint should be dismissed, you will receive a letter outlining the claims that will be investigated and identifying the claims that will be dismissed. You may not appeal the dismissed claims at that time. The letter you receive will explain when and how you may appeal any dismissed claims.
