Review of ZeroBounce


Rated 4 out of 5 stars

Essential tool for sending any volume…

Essential tool for sending any volume of emails. Very easy to use. When I've talked with email consultants they nod approvingly when I say we use ZB. We've tried 1 or 2 other services bundled in with other tools but didn't get the detail or the results ZB provides.

That said: if you're sending to B2B addresses you're more likely to get "catch-all" which basically means it's an unknown. (That's just how email works) We don't find all of the additional insight/data offered that helpful but hopefully that evolves. Support is fine, sometimes feels like one of us has misunderstood but we get there soon enough and they are responsive.

Thanks so much for the detailed feedback, Dan! We’re thrilled to hear ZeroBounce has become an essential part of your email process and that consultants recognize its value too.

You’re absolutely right about catch-all addresses — they can be tricky, especially in the B2B world. We’re always looking for ways to improve the additional insights we provide, and your perspective is really helpful.

It’s also great to hear our support team has been responsive, and we’ll keep working to make sure communication is as clear and smooth as possible.
