What's the best to start a cover letter with:

"To Whom It May Concern"


"Dear Sir/Madam"

It's a letter to an American company in Europe.

I know, the best is to apply personally but can't get any name.

Thank you.


You can't go wrong with 'Dear Sir or Madam'.


Broadly speaking, To Whom It May Concern is only used if you are writing a letter of reference for an employee.
