Dear ms
His Excellency, Ambassador of ................... This salutation can be used when writing to the Forein ambassadors of all countries.
Dear Sirs and Madam:
Consul of China
Honorable Consulate
Walter J. Smith, Jr., MD. Never use Dr and MD (or PhD) in the same name.
I BELIEVE THE CORRECT FORM WOULD BE: DEAR DR. AND MRS .....
If being formal, he/she is referred to as doctor.
Dear Father, Dear Reverend Father or Most Reverend Father
The proper salutation when writing to a judge is "Dear Judge [Last Name]" or "Your Honor."
Desmond Tutu was a Bishop, so the correct salutation would be, "Your Excellency".
the correct salutation for two men is Messrs
Sir and Ma'am. Or, you refer to them by their rank, as in "Greetings, Colonels Smith."
