You do NOT need to write any addresses.
Begin your letter as follows:
Dear Sir or Madam,

Write at least 150 words.

MODEL ANSWER:

Dear Sir,

I am a regular reader of your publication and I am writing this letter to suggest some modifications in its layout.

Since 2012, when I assumed my new post as the marketing manager in my office, I started reading your magazine: ‘The Market and the Customer’. As days advanced, I became involved in your articles and started practicing some of the strategies which the marketing experts suggested to enhance the sales of products and services. I admit, it has made my success rate improved greatly.

However, recently, I can find most pages have irrelevant advertisements which are not so interesting for a reader who has interest in the field. I think, this would fade your reputation and goodwill, and hence I suggest you to avoid such. I would also like to suggest you to have innovative strategies included in the magazine.

I would be grateful if you would attend to this matter as soon as possible.

Yours faithfully
(Name)
