Hi there, I am a new UX Designer and looking for an answer of the question. How do you find user/s from existing website? What tool you use? I want to interview 5 people say for example, who are using my product, but how to know them specifically by name so that I can personally ask them for user interview through site or email? Can you please share your quality advice with me and helo me asap.
Hey there. Welcome. 
You could customise an exit intent survey asking people if they’d be open to doing a short interview.
