How do I add a note to contact?
There are two ways. You can add a persistent comment in Contact > Edit > Comments about this contact. It will always be visible on contact preview. To add a time-sensitive note, such as meeting results, add activity. You may label it “Note” or create any other descriptive label for the line-items of this type.
