Email Verification and Validation

I'm looking to get a small list (under 2,000) validated. Zerobounce often shows up in searches on BHW.

Does anyone know:
Is the accuracy is typically accurate?
Is one site easier/smoother to navigate?

Anything I should avoid?

The accuracy is not always accurate. You will get highest bounce if you are sending spammy contents.
