When writing a formal letter addressed to someone whose gender is unknown, how important is it to use "Dear Sir or Madam", instead of "Dear Sir"?

I was taught that "Dear Sir" is an acceptable gender-neutral salutation but times may have changed, is this right or wrong?

Dear Sir may have been an acceptable gender-neutral salutation some time ago, but I would suggest 'To whom it may concern,' as a more modern and suitable alternative :)


When the addressee is in the same field as the writer, you can use the address Dear Colleague.

    Don't you find that it always rains when you try to write a letter in a field? Sep 5, 2013 at 7:17

    @EdwinAshworth No, because I am not a man out standing in his field.

The proper way to begin a formal letter to someone whose gender is unknown is with the "Dear Sir/Madam," phrase while At the end the letter use the phrase "Yours faithfully," plus your full name, like the template that follows:

Dear Sir/Madam,


Yours faithfully, Your full name
