A proper word to address a mam in mail

When addressing a mother in a formal or professional setting, such as in a letter or email, it's generally considered polite to use a title and last name, unless she has explicitly requested otherwise. Here are some options:

1. Mrs. [Last Name]: This is a classic and respectful way to address a mother, especially if you don't know her first name.
2. Mother [Last Name]: This is a more formal and affectionate way to address a mother, especially if you have a close relationship with her.
3. Ms. [Last Name]: This is a more modern and professional way to address a mother, especially if you don't know her marital status.
4. Dear [First Name] [Last Name]: If you know the mother's first name, you can use it in a formal letter or email, followed by her last name.

Here are some examples:

• Dear Mrs. Smith
• Dear Mother Johnson
• Dear Ms. Thompson
• Dear Sarah Johnson

Remember to always use a formal greeting and closing, such as:

• Dear [Name]
• Sincerely,
• Best regards,
• Respectfully,
• Yours faithfully,

It's also a good idea to proofread your letter or email carefully to ensure that the address is correct and the tone is respectful.
