What are you guys using to extract leads from an email list? More specifically, I need to go through an email list and filter out all the email adresses for people working in agencies.
I know Clearbit can do something like this, but I’m not sure how good it is. Their free trial quota is way too low to tell if it works or not. Does anyone have experiences to share?
I was thinking about outsourcing it. Good or bad idea? Suggestions?
