Do not put a comma between your first name and surname. Alex just put the comma there to separate the two words.

Also Dear Sir/Madam, the letter would be signed as (yours truly,)

You would only use �thanking you � to someone you know, the other terms are �best wishes �, �kind regards � or �regards �.

 

I think all English speaking countries use slightly different formats.

 

Down here at the bottom of the world we don�t put punctuation after the greeting. In fact, comas and fulls stops generally no longer appear in address fields, after greeting or closing or after Ms/Mr.  Gov�t letters usually follow a set format which private business then also follows. Naturally, there are many exceptions though with non-gov�t letters as we have all been taught differently over the years.

 

One thing is standard though and it�s the closing which is the same as what Alex has written

 

You can see an example business letter here (with a subject) and read more info here.

 

Cheers
