My verdict: a hidden gem to use without moderation.
I love Enrow. It's one of my top 2 tools when doing waterfall to find emails. The value for money and ease of integration are excellent.
I much prefer it to Dropcontact, Apollo or Hunter. Data quality delivers, the API is a pleasure to use, and pricing is honest.
What I like less: honestly not much. Coverage on some markets (especially US) may be slightly less than Apollo, but for Europe it's excellent.
My advice: if you do email enrichment, test Enrow. You might replace your current tools. That's what I did.
