My verdict: in my top 2 for email enrichment, essential in my stack.
In my top 2 for waterfall workflows (with Enrow). Very good discoverability and excellent data quality.
It's an essential tool in my stack. If you're looking for pure performance in email discovery, go for it.
What I like less: the interface is a bit less modern than some competitors. But for what it does, that's secondary.
My advice: if you do email enrichment, test Icypeas. Combined with Enrow in a waterfall, it's formidable.
