Stay away, it does not work
I purchased 250,000 credits and run 2 tests. First a benchmark of 100 emails and second 25,000 emails to verify. On the first, NeverBounce only identified 11 as deliverable while other 3 services found 58 as deliverable. I sent the emails and 58 were dellivered. On the second test, NeverBounce provided a result for only 770 emails out of 25,000, others as unknown or unverifiable. They charged all credits although it is useless. I requested a refund but they said it is not possible. I will dispute the charge. Go find something more expensive but useful.
