Sending an unsolicited article to a magazine
I have written an article suitable for children of school-going age. I have enclosed a copy of the article with this letter. Perhaps you might kindly have a look and see if you like to see it in your magazine.
I shall be happy to make changes or even rewrite the article if you find anything lacking with the present one. I hope to hear from you soon. I have also included a stamped self-addressed envelope for your convenience.
