Personal and Confidential Mail

Personal and confidential mail is a type of mail that contains sensitive or private information, such as financial information, medical information, or legal documents. These types of mail should be treated with extra caution and security, as they contain confidential information that should not be shared with anyone else. There are times when you write on behalf of yourself rather than for the entire company. This chapter includes samples to help you write personal and confidential business letters.

What do personal and confidential mean?

What could be in a private and confidential letter?

A private and confidential letter could contain sensitive information such as personal financial information, health information, legal documents, private business dealings, and any other information that the sender and recipient want to keep private.

How do you address an email with confidential information?

When sending an email with confidential information, it is imperative to ensure the recipient is the intended recipient. You may consider using a secure email service that encrypts emails with a passcode or a password-protected document to share confidential information. Additionally, you should include a disclaimer in the email that the information is confidential and should not be shared with anyone else.

Is it private and confidential or personal and confidential?

It depends on the context. Generally speaking, private and confidential is used to refer to information that must not be shared with anyone outside of a designated group of people, while personal and confidential is used to refer to information that is more sensitive or intimate.

How do I mark a document private and confidential?

To mark a document as private and confidential, you can add a phrase such as “Private and Confidential” or “Confidential and For Internal Use Only” at the top of the document. You can also add a watermark to the document, such as “Confidential” or “Private”. Depending on the sensitivity of the document, you may also want to consider encrypting the document or password-protecting it.

Mail or Confidential Notation

Business-oriented letters may also include a notation indicating any special handling your letter should receive:

“Confidential” indicates that no one but the addressee should read this letter.The envelope, too, should indicate that a letter is confidential. For emphasis, write these notations either in all capital letters or underlined with initial capitals: Certified Mail.

Social letters typically do not include these notations. Also, remember that e-mail is not the right forum for confidential disclosures.


Use this word when the person to whom the letter is addressed is the only one who should read the letter. Physically separate the word from the rest of the letter by two lines. To assure confidentiality, include the word “Confidential” on the envelope.


Most business letters originating from a firm are written on the firm’s letterhead. If you are writing a personal business letter or your firm does not use letterhead, then you need to include your firm’s address in the heading.

It is likely that your organization may prefer one form over another. In the following explanations, the assumption is that you will be using letterhead stationery. If you are writing a personal business letter without letterhead, place your address one line above or below the date as in the following examples:

August 3, 20XX
Any number, Any road
Any city


Any number, Any road
Any city
August 3, 20XX
