It's not just about not having your name. Depending on the subject of your letter, make the letter seem very vague. You DO have detail, but depending on your personality, don't make the letter seem obvious it's you.
By saying what you want but without your name on it
To write an anonymous letter, identify your purpose, choose your format, and write the body including an introduction, details, and a conclusion. Ensure you omit any personal information to maintain anonymity, then proofread and decide on the delivery method. These steps will help you effectively communicate your message without revealing your identity.
