What does FYI mean?
FYI indicates that a message is for informational purposes only and doesn’t require further action right now. You can use FYI in a few different ways: as a sort of label for information, as a way to draw attention to a key detail, or as a way to introduce information that someone didn’t ask for.
Since it’s an initialism, the correct way to write FYI is with all three letters capitalized. However, since it’s also used casually, you may also see “Fyi” or “fyi.”
FYI can be used in various contexts, like email, text messages, and chats.
FYI in email
FYI often appears in informative emails to make sure the reader knows about an important event or detail. It might be in the subject line or in the body of the email.. In this context it’s usually capitalized to look more professional.

FYI in text messages
Since texting is an informal context, FYI might be lowercased in text messages.

FYI in chat
Like texting, chatting is casual, so FYI may be lowercased here as well. In chats, especially those connected to video games or streaming platforms, you’ll probably see other abbreviations—like AFK—used too.
