"Perfect service and simple to use"

Perfect service and minimalistic design. I use this service every day for validating email list, and it works. No bounce and no problem.

"Really nice working service"

Really nice working service, happy with the results! I checked 300 emails and didn't know what to use for my emailling. Highly recommend especially their API

"An amazing service"

I've never tried this service before but when I tried, the service is user-friendly, everything easy to understand, the big bonus they work pretty fast, plus it's cheap.
