When is calendly inappropriate in a business context?

I’ve read Sam Lessins tweet about scheduling again. I personally thought about scheduling as follows: - internal -> calendar (google calendar/outlook) - external/inbound -> calendly - external/outbound -> email & manual exchange After talking about this yesterday with @chris_hahn2, we wondered: how does the ProductHunt community think about scheduling and its automation?
