Thank you all! I don't think the client runs many events, so it will likely have to be email based.
This is all super helpful. My 1st company where I led global customer marketing was in the hardware space (3D printers), so review sites weren't really helpful for them compared to enterprise software companies. And then at SAP, we had a dedicated reviews team (bet we all wish we had something like that!).
Appreciate all of the advice. It's one area I've just not really touched.
