In the salutation line of a letter addressing multiple men and women, you can use "Dear All" or "Dear Team" for a neutral and inclusive approach. If you prefer to be more formal, you can list the recipients, such as "Dear Mr. Smith and Ms. Johnson," or simply "Dear Mr. Smith, Ms. Johnson, and Team." If there are many recipients, "Dear Colleagues" can also be appropriate.

When greeting multiple women in person I would say "Hello ladies".
If you are addressing several men and women in a letter, then the salutation can be 'Dear Ladies and Gentlemen'. Another salutation can be 'Sirs and Madams'. These types of salutations can be used for men and women that are on a committee.
To address a letter to several people, you would include each recipient's name and address in the address block. The salutation would be "Dear Sirs and Madams" if you are not familiar with the recipients. If you are on familiar terms, you would address as "Dear Jack and Jill." If you are addressing a letter to a company or entity and you are not addressing a particular individual, you would use "To whom it may concern." That salutation is inappropriate when you are addressing particular individuals.
The proper salutation for a female can vary depending on their marital status. Mrs. is used for women who are married. Miss is used for women who are single, while Ms. is used for women who are both married and single. This salutation is safer to use if one is unsure of the woman's marital status.

Gentlemen and Madams
In English, the salutation for a doctor, whether they are a medical doctor or the holder of a Ph.D. is the same for both male and female. It is Doctor.

The proper salutation in English for either a medical doctor or the holder of a Ph.D. is the same for either male or female. It is simply "Doctor".
I would use "Ladies and Gentleman" or if it is just women "Ladies" or if it was just men" Gentleman" if that makes any sense. Hope this suggestion helps you.
