Some Red Flags Here **Rating:** 1.0/5.0 stars **Reviewed by:** Verified User in Publishing | Marketing Director, Mid-Market (51-1000 emp.) **Reviewed Date:** February 09, 2026 **What do you like best about NeverBounce - Powered by ZoomInfo?** When we started using them 6 years ago, we liked their service. Affordable and only occasional bugs. **What do you dislike about NeverBounce - Powered by ZoomInfo?** When we originally became a customer of Neverbounce 6 years ago and integrated them into our systems, there was no expiration date on prepaid credits. That was part of the purchasing decision for us, as our use case involved variable quantities of new leads that we use the Neverbounce API to check before adding them to a drip sequence. In 2024, they introduced an expiration date on credits in fine print on the pricing page. I'm guessing this is a way to increase the revenue without raising the price, since there is no real-world reason why the credits need to expire. It’s like the Post Office announcing that all unused forever stamps will expire in a year and adding an expiration date to any stamps made in the future. This is a pretty major shift for customers who have already written software around their service. I reached out to their customer service asking for a resolution, and they seemed apologetic but said nothing could be done. I see this is a common complaint with the company, and in looking at their website I also noticed they advertise 7,000+ G2 reviews with a 4.5-star rating. As of today, they have 138 reviews and a 4.2-star rating. I don't know what else they're lying about, there could be more things, and it certainly leaves me wondering about the accuracy of their product. I'm currently looking for a replacement service to transition to. **What problems is NeverBounce - Powered by ZoomInfo solving and how is that benefiting you?** They are verifying web leads before we add them to a drip campaign ### 2. Costly and Lacks Promised Features **Rating:** 2.5/5.0 stars **Reviewed by:** Clare S. | Sr. Associate, Small-Business (50 or fewer emp.) **Reviewed Date:** April 27, 2026 **What do you like best about NeverBounce - Powered by ZoomInfo?** I liked that NeverBounce did what it said it would do. It was fairly easy to use, even though it took some time to import spreadsheets. **What do you dislike about NeverBounce - Powered by ZoomInfo?** I was sold by the salesperson that it would be a tool that would be useful for verifying both personal and work emails all at once. However, once I received the tool, I realized how expensive it was and it did not actually do that feature. It could only do one email at a time, so it did take a long time to get through lengthy lists. It was easy because we were sold into it, but it did have a bit of a learning curve. It was a little bit tedious to use. **What problems is NeverBounce - Powered by ZoomInfo solving and how is that benefiting you?** I used NeverBounce to verify business and personal emails for cold outreach, which helped protect my business's domain by reducing bounce rates. ### 3. Reliable Validator with Seamless Integration **Rating:** 4.5/5.0 stars **Reviewed by:** Charles C. | Senior Product Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** December 16, 2025 **What do you like best about NeverBounce - Powered by ZoomInfo?** I like that NeverBounce is very simple and straightforward to use. I used to mostly rely on CSV uploads for bulk verification, but I really appreciate how well NeverBounce integrates with my other tools, allowing me to validate emails through API calls now. It's quick, and having access to a large dataset really builds my trust in the results. The API calls simplify steps and allow for more automated workflows, while CSV uploads, despite being a bit more manual, are still very quick for large lists. The setup was incredibly easy, and integrating it with more automated workflows was seamless. **What do you dislike about NeverBounce - Powered by ZoomInfo?** I'm disappointed with NeverBounce's policy of adding expiration dates to their credits. When I first started using them, their credits did not expire, and I had a really big bank of credits to use. They seem to have retroactively applied an expiration date to credits that were already purchased, which was disappointing. Although they were kind enough to give me an extension on that expiration deadline, I would have preferred if they had applied the expiration date only to credits purchased after the announcement, rather than backdating it. **What problems is NeverBounce - Powered by ZoomInfo solving and how is that benefiting you?** I use NeverBounce to enhance data quality by cross-checking emails from multiple sources, boosting my confidence and ensuring email delivery. ### 4. Efficient Email Verification, Needs Pricing Adjustment **Rating:** 3.5/5.0 stars **Reviewed by:** Vatsal N. | Founder, Internet, Small-Business (50 or fewer emp.) **Reviewed Date:** April 30, 2026 **What do you like best about NeverBounce - Powered by ZoomInfo?** I like that NeverBounce has a really good API with high data limits. This makes it easy to verify thousands of emails at a single go without any problems. The initial setup is very easy and straightforward, and I also appreciate how it integrates smoothly with Clay. **What do you dislike about NeverBounce - Powered by ZoomInfo?** The pricing stings a bit. I feel like it could have been a bit cheaper. **What problems is NeverBounce - Powered by ZoomInfo solving and how is that benefiting you?** NeverBounce's API allows us to verify thousands of emails at once efficiently, enhancing our email campaigns. ### 5. Neverbounce got me banned from my email marketing provider then refused to help **Rating:** 0.0/5.0 stars **Reviewed by:** Verified User in Computer Games | Small-Business (50 or fewer emp.) **Reviewed Date:** January 26, 2024 **What do you like best about NeverBounce - Powered by ZoomInfo?** Pay as you go pricing is reasonable, interface easy to use **What do you dislike about NeverBounce - Powered by ZoomInfo?** The quality of the service does not meet their guarantees and they took an extremely long amount of time to reply, and offered zero refunds **What problems is NeverBounce - Powered by ZoomInfo solving and how is that benefiting you?** I wanted to clean some emails that I hadn't contact in a while and NeverBounce I had used in the past. Unfortunately, their error rate was 1 in 8, which is substantially higher than their claims. When I confronted them about the egregious errors, they took weeks to reply, offered no refund (contrary to their marketing claims), then shirked responsibility. Extremely shady practices! ### 6. Easy, No-Fuss Interface, But Bounce Insights Feel Too Vague **Rating:** 3.5/5.0 stars **Reviewed by:** Mujtaba H. | Research Analyst, Mid-Market (51-1000 emp.) **Reviewed Date:** May 11, 2026 **What do you like best about NeverBounce - Powered by ZoomInfo?** It has an easier interface - pretty basic, quick and gets the job done. **What do you dislike about NeverBounce - Powered by ZoomInfo?** It doesn't give me insight of why the email bounced. Only gives me very vague numbers to deal with. **What problems is NeverBounce - Powered by ZoomInfo solving and how is that benefiting you?** I can run my emails through NB. It gives me a list of Emails I shouldn't move ahead with and that is big help. ### 7.

And the support is good as compared to competitors. **What do you dislike about NeverBounce - Powered by ZoomInfo?** Additional data for catch-alls with some tips on when to add them to the campaigns vs when not to **What problems is NeverBounce - Powered by ZoomInfo solving and how is that benefiting you?** Deliverability of my email campaigns ### 8. Very Helpful for Verifying Emails Before CRM Upload **Rating:** 4.0/5.0 stars **Reviewed by:** Dylan B. | Contributing Writer, Mid-Market (51-1000 emp.) **Reviewed Date:** April 02, 2026 **What do you like best about NeverBounce - Powered by ZoomInfo?** Very helpful for verifying emails before we upload into the CRM. **What do you dislike about NeverBounce - Powered by ZoomInfo?** It's not always one hundred percent accurate. **What problems is NeverBounce - Powered by ZoomInfo solving and how is that benefiting you?** We don't want to upload a bunch of faulty emails into the CRM, so we spend the money to check. ### 9.

The initial setup was very easy. **What do you dislike about NeverBounce - Powered by ZoomInfo?** I don't like that since NeverBounce was acquired by Zoominfo, the experience has been terrible. The pricing raised by 300% in one month, which is outrageous. Their support is really bad now and they never get back to you anymore. We cancelled our subscription because of these issues. **What problems is NeverBounce - Powered by ZoomInfo solving and how is that benefiting you?** We use NeverBounce to validate our emails, checking if they are valid or not. ### 10.
