# #2 NeverBounce

NeverBounce, owned by ZoomInfo, is an email verification service that cleans uploaded lists and verifies addresses in real time through an API and integrations such as HubSpot, Mailchimp and Zapier. Website: neverbounce.com. Category: [Email Infrastructure & Verification](https://gtmranked.com/best/email-deliverability/). Score 17/100 (3 positive, 2 mixed, 5 negative of 10 independent comments).

**Verdict:** 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.

**What users like:**
- Users who have run lists through it describe the results as accurate for basic validity checks [1](https://www.reddit.com/r/DigitalMarketing/comments/1k16pnz/_/mnl5prt/) [2](https://www.reddit.com/r/DigitalMarketing/comments/1p1zc6f/_/nq3ds9u/) [3](https://www.reddit.com/r/Emailmarketing/comments/1rkfayc/_/p3mepk8/)
- Returns your file in the layout you uploaded with a status column added, which makes it easy to route verified and unverified contacts into different campaigns [1](https://www.reddit.com/r/Emailmarketing/comments/10rt0zn/_/j70a6gj/)

**What 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](https://www.reddit.com/r/Emailmarketing/comments/1bsft16/_/mldhksc/) [2](https://www.reddit.com/r/Emailmarketing/comments/1bsft16/_/mf9rj1s/) [3](https://www.reddit.com/r/Emailmarketing/comments/1akuq73/_/kpasgxj/)
- Catch-all and Yahoo addresses are a weak spot: one user saw invalid Yahoo addresses marked valid and a 15 percent bounce rate [1](https://www.reddit.com/r/Emailmarketing/comments/sjqe6z/_/hwxbynp/) [2](https://www.reddit.com/r/DigitalMarketing/comments/1p1zc6f/_/nq3ds9u/)
- An early-stage team calls the API pricing too steep to sustain [1](https://www.reddit.com/r/Emailmarketing/comments/1rkfayc/_/p3mepk8/)
- 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](https://www.reddit.com/r/Emailmarketing/comments/10rt0zn/_/lf1mogl/)
