MillionVerifier shows up constantly as the default list cleaner in cold-email stack advice, but only about ten of the 100 comments give a first-hand opinion, and roughly a third are promotional, mostly answers that name it on the way to plugging a data provider or another verifier. Independent users agree it is cheap and good enough for routine bulk cleaning. Critics say it handles catch-all domains poorly and that some addresses it passes still bounce, which is why several users run a second verifier after it.
Users like
- Cheap per verification: users call it very affordable, cheap enough for a few thousand emails a month, and the best value they have found against pricier verifiers[1][2][3][4]
- Results hold up for routine list cleaning: users describe them as solid and fast, say it catches most role addresses, and one regular user says it works great[1][2][3][4]
Users complain about
- Weak on catch-all domains: one team that ran repeated campaigns found it marks some catch-alls as valid even though they turn out undeliverable[1]
- Some addresses it passes still bounce: a regular user found verified contacts hard-bouncing, and another says bounces dropped sharply after moving to a different verifier[1][2]
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.

Users complain about
- Cleaned lists still bounce: on Apollo lists users saw a large share (one says 30 to 50 percent) flagged invalid while the remainder still bounced, and another user stayed around 3 percent bounces[1][2][3]
- Catch-all and Yahoo addresses are a weak spot: one user saw invalid Yahoo addresses marked valid and a 15 percent bounce rate[1][2]
- 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]
