When emailing the company I have applied for a job at. Shall I begin my email with 'Dear Sir/ Madam' or 'To whom it may concern'
That's a great question.
I would use 'Dear Sir or Madam' because for me it seems slightly more personal and I care about the response whereas I have only used 'To whom it may concern' when either I have no idea about the structure of the body to which I am writing and the implication is that anyone will do or when I have not cared about the response e.g. in some resignation letters.
Personally, I wouldn't use 'To whom it may concern'- I only use that when the letter could be shown to various or completely unknown people- references, health letters, etc. I'd try to find a name, but failing that would use 'Dear Sir or Madam'.
