This is the best email verification service I've used so far. And the cheapest, by far. The accuracy is excellent and you get the most bang for your buck.
I have used their service and it's pretty good. They have the cheapest plans in the market and very good accuracy.But their service is a little slow when you upload multiple bulk verifier files. But I can't expect faster servers for the money I paid, I am satisfied.
