I changed my call recently from W6JHB to K7TXA. When I log into groups.io and go to my Account, it shows me as w6jhb@..., which, for the time being is the correct and valid email address. If I look at my WSJTX subscription, it shows me as getting Daily Summary.

At one time I had been using w6JHB@... for my email address, but I no longer receive any groups.io messages to that account. Yeah, confusing, I know.

So, where are you looking to see that I get individual messages?
