I think Warmly, is affront to the very idea of the SaaS business model.

In my opinion, stay away from this service. I tried Warmly, because my CSM at another software company was using it and I thought it looked interesting. Huge mistake. Once they had access to my Microsoft 365 account they proceeded to add a Warmly, profile to every member of my team that was included in a meeting invite, sending an update to the event fifteen times before I realized what was happening. I think this is an unconscionable overreach for a gimmicky service intended to eliminate the need to tell people your name in a Zoom meeting. In my experience, definitely top three worst customer experience.
