Somewhat related to this thread: I received an "How's the R2?" email from Netduma with a survey, which I wanted to fill out of course, as a happy customer. However, the 'Give Your Response' button is unclickable (all other links are clickable) and when I open the email in my browser, I can click it but it just redirects me to the same email. So perhaps an issue with the email / survey, or something on my end?
