Thanks to modern marketing, my personal inbox has been filling up with pleas from a host of organizations wanting me to Join. (I suspect that one-time donation back in November put me on a list that has triggered an open invitation to my Gmail, but that’s another story.) Some of these emails have even worked, and I’ve joined a few groups in recent months. What I’ve learned is that the groups I’ve become most engaged with are those that not only got me to read their email and join, but who involved me after I hit the “Join Now” button.
