@johnny thanks as always for offering help!

Do you think if the unsubscribe button in an email was clicked, I could hack together a way to add an unsubscribe id that when unsubscribe button in an email is clicked would open a window for a page on the app (call it “unsubscribe_page”) with a URL parameter of the unsubscribe ID & User ID and if the app detects that it will run a workflow to change the yes/no field for that User?

Create the unsubscribe ID and link it to a User for whenever the unsubscribe button in an email is clicked in the future and all the other supporting stuff to make it work.

Similar to how Joe from No Code Academy did User Invite feature in this video: https://youtu.be/5O06Ip2Zt1M?feature=shared
