Assuming you mean a woman with the title "Lady". On the envelope put "Lady Jane Doe" before the location address. For the salutation in the letter use "Dear Madam" or "Dear Lady Jane"
If you are talking about a woman who holds a position of power (e.g President) Use "President Jane Doe" on the envelope. "Dear Madam President" in the salutation
If you mean any woman, use Miss or Mrs. before her name on the envelope if you know her marital status, Ms. if don't (or if this is her preference). The salutation should be "Dear Miss/Mrs./Ms. Smith" if the letter is formal, "Dear Jane" if a friendly letter to someone with whom you are on a first name basis.
Unfortauntely, we don't know the address of your land lady. However, If you're trying to address a letter to your land lady you'd just address her as Ms. or Mrs. depending on if she married or not.
Dear Madam ________,
dear first lady,
Dear Mr. _________________, CEO:
The Honorable ____________ (even when you know he isn't)
In the address line: The Right Honourable the Countess of (whichever district she is Countess of) In the letter body: Madam or Dear Lady (name of her district)
To address a letter of recommendation properly, start with the recipient's full name and title, followed by the organization or institution they are associated with. Be sure to use a formal salutation, such as "Dear Recipient's Name," and maintain a professional tone throughout the letter.
u can use, from a stranger or another funny names.
To properly address a letter to the lieutenant governor of a state, begin with "The Honorable [Full Name]" followed by "Lieutenant Governor of [State]" on the next line. Include the address of the lieutenant governor's office below that. For the salutation, use "Dear Lieutenant Governor [Last Name]."
You could simply say, "Dear Sir/Ma'am"
You can address them as 'Sir' if they are a man, ' Miss' if you do not know if the lady is married or not, 'Madam' if you know the lady is married. If you are writing a letter, and you do not know the gender, you can address him/her as 'Dear Sir/Madam'. If you do not want to use any of the above, you may use 'excuse me'. Hope this answers your question :)
You want to address them as "Honorable [full name]"
