Pros

“ZeroBounce offers easy setup, strong spam detection, great support, and good value for teams.team collaboration features that make managing and verifying email lists efficient across departments.”

Bhanu L.

Growth

“It made list hygiene easier by quickly identifying obvious bad addresses and highlighting risky segments (spamtraps/abuse/unknown). Once you define internal rules for how to treat catch-all and other edge cases, it becomes a strong, repeatable part of an email deliverability workflow.”

Connor C.

Director, Email

“I think its a powerful tool to help companies reduce their spam when prospecting new regions, helping emails to stay safe from spam folder”

Alvaro S.

Owner

Pros

“Best tool for startups and SME's. If you can't pay premiums for tools that are the most accurate like Emailable, MillionVerifier is a great option.”

Leana Y.

Marketing Director

“It's a great tool for small to medium businesses, not so much for Enterprise since they're not that accurate for spam emails.”

Diana B.

Founder

“They do have sporadic downtime.”

Leana Y.

Marketing Director

Cons

“In particular, the account verification emails were unreliable, the verification link consistently failed, making it difficult to complete the registration process.”

Rishav K.

GTM Engineer

“The credits that come with our subscription are not flexible enough, we have too many credits for functionalities that we don't use.”

Boryana A.

Customer success manager

“Additionally, some of the validation categories require interpretation, which can create minor uncertainty around borderline results if you are new to email verification tools.”

Finn J.

CEO

Cons

“It feels a bit spammy sometimes.”

Diana B.

Founder

“This is just a shell company now with no real humans behind it. If you run into any issues at all, good luck getting help or your money back.”

Bryce M.

Founder

“That was incorrect and my source for that data was very wrong.”
