I want to send Apple a letter and I don't know how to start it.
Dear Apple employee? I don't know who will read it.
You write to the Company.
Then the address you are writing to.
A heading about the subject of the letter or any reference you have. (Do this in bold)
Then your text
and end Yours faithfully
Note 'To Whom it May Concern is usually for letters of recommendation etc where the author does not know to who he is writing. You do, and that is a company with a board of directors, hence Dear Sirs.
