List of angel investors? I will not promote

Is there a platform where startups can find a list of angel investors investing in their sector? I understand Crunchbase "has this" however you have to have a business subscription which costs $2,400 a year to buy contacts and even then you don't know which of the angles actually have their email address listed unless you pay which is mind blowing to me. Are there alternative platforms? Or am I stuck to Linkdein?
