I used Glassdoor to get a rough idea of what salary to ask for when I moved countries. Same issue as you. It massively peevs me when I want to download a free-to-try piece of software, or a whitepaper and they require my email address so they can mail me the link. So I did what I always do when something that shouldn't seemingly require an email address, forces me to register. I used a disposable email address (Yopmail is my favourite one :)) Did it add any value to process? Not particularly. If I like what you have to offer, then I will go back and sign-up for the newsletters, until then, stop filling up my inbox with random rubbsih!
