K9 mail icon meaning

The K9 mail icon!

The K9 mail icon is a symbol used to indicate that an email or message contains a file or attachment that is in the format of a Microsoft Office document, specifically a Word document (.docx) or PowerPoint presentation (.pptx).

The icon is a stylized representation of a dog's head, with the name "K9" being a reference to the canine species. The use of a dog's head as an icon is thought to be a nod to the idea that the file is "paws-itively" safe and secure.

In other words, the K9 mail icon is a visual cue that lets the recipient know that the email contains a Microsoft Office document that can be opened and viewed using Microsoft Office software.
