We created a list of bidders from the prior event to facilitate set up for this year's event. Obviously not all bidders from 2019 were in attendance in 2020. So when it came time to communicate with only those attending (or, indeed, any subset of the database we wanted to contact), we were not able to do this within RSA, but had to download the data-set, edit in Excel, and then use our regular ConstantContact mail capabilities. Being able to do this within RSA would have been significantly easier.
