Hey! I dig the UI, but outside of that there's probably 40 other companies who all do the exact same thing. Plus one from Atomic Mail which does unlimited for $40. What's your UVP here?

Kickbox ensures you only send email to real users. Just drop your contacts directly into the Kickbox interface and it helps you separate the low-quality addresses from high-value contacts.Verify email addresses within your application using its Real Time API.

I've used KickBox and was really happy with it. Compared to other services, it was really easy to use and all worked fine.

A really good provider for email verification. I would really like if they can detect duplicate entries or remove Habitual complainer from a list like some other provider mentioned here.
