My verdict: the essential tool if you use LinkedIn Sales Navigator.
Evaboot exports and automatically cleans your Sales Nav searches in one click: verified emails, duplicates removed, data formatted cleanly. No more sales exports with garbage emails.
The tool also enriches missing data and verifies deliverability. Starting at 29€/month for 1000 credits, it's a must-have if Sales Nav is at the heart of your prospecting.
What I like less: useless if you don't have Sales Navigator. And for scraping outside LinkedIn, you'll need other tools.
My advice: if you use Sales Nav, go for it. The interface is simple, it works first try, and time saved is considerable.
