What do you mean for reference only?

FYI is the abbreviation of For Your Information, which is interpreted in English as: information provided for your reference is a popular English abbreviation in foreign companies and also a working term.

Reference messages are now mainly used for email and SMS. The specific intention is to tell the recipient that the information content is understood, and there are two common ways to use it:

1, for your reference.

FYI is often written at the end of the email body, and then the attachment usually has photos, videos or other documents, indicating that it is for the recipient's reference. The abbreviation is FYR.

Please understand this.

Simply let the recipient know the content and information in the email, and there is not necessarily an attachment.

Matters needing attention

It is for reference only and cannot be used for leadership. This word is correct, but it is rarely used. The word "please know" is usually used. Everyone can use the word "please know" as the conclusion of the email, but it is not common for subordinates of their own company or unit to send emails to their superiors. Because the word "know" is too narrow, it usually makes the leader think that what you wrote to him only let him know the result of what you did, without him pointing out other requirements or guidance.
