I’m interested in seeing if anyone has problems reaching their entire user base? I work for a TV/ Video Entertainment company. When recruiting for UX Research studies, I can access a customer list of account holders and easily gain access to them, but I have to keep in mind that not all of our users are primary account holders. In other words-one account can be for an entire family, but the information we have on that account is only for the one paying the bills. I want to be able to recruit to the larger user base.
What are some different ways you have used to recruit for user research studies & participants?
