The fact this isn't already a thing boggles me. If you click email under a contact name, that email should inherently be logged and tracked on all future communication in that thread under activity. This is literally out of the box solution with competitors like hubspot. Telling my customers to remember to BCC a special email every time or we need to buy yesware for such a small function will not work. Also, if it isn't already, M365/outlook should be figured out BEFORE gmail. M365 is adopted by the majority of businesses.
