Independent users who report on ZeroBounce mostly describe it as an accurate, established verifier for list cleaning, but price is the recurring complaint and its accuracy is disputed on B2B lists, where one user says conservative risk scoring bins valid addresses. About two-thirds of the 49 Reddit mentions are promotional, including a one-day burst of near-identical posts pitching FilterBounce, DoYouMail and Mystrika as ZeroBounce replacements, repeated plugs for one cheaper verifier, and seeded Prospeo switching stories, so this rests on about ten independent opinions, most of them brief.

Users complain about
- Expensive: users call it pricey, and an early-stage team says the API pricing became too heavy[1][2]
- Accuracy is contested on B2B data: one team left over low accuracy, and another says its conservative risk scoring pushes good startup addresses into the risky bucket[1][2]
- Cleaned lists still produced bounces for users verifying Apollo leads[1][2]
- A customer verifying a large HubSpot database says support treated them like a nuisance and is looking to replace it[1]
The few independent users who report first-hand find NeverBounce accurate enough for basic list cleaning and easy to work with, but its weak spot is lists where bounces persist after cleaning: Apollo-sourced B2B data, catch-all domains and Yahoo addresses. More than half of the 48 Reddit mentions are promotional, led by a cluster of near-identical comments steering readers from NeverBounce to one cheaper verifier, so independent discussion is thin, about ten opinions, most of them brief.

- An early-stage team calls the API pricing too steep to sustain[1]
- One former user alleges that after cleaning a niche list with NeverBounce, the companies on it began appearing on NeverBounce pages that publish their email formats, and quit over it[1]
