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?** When we started using them 6 years ago, we liked their service. Affordable and only occasional bugs. **What do you dislike about NeverBounce?** 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 solving and how is that benefiting you?** They are verifying web leads before we add them to a drip campaign ### 2. 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?** 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?** 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 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. ### 3. 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?** Pay as you go pricing is reasonable, interface easy to use **What do you dislike about NeverBounce?** 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 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! ### 4. No-Nonsense Ease of Use with Strong Support **Rating:** 5.0/5.0 stars **Reviewed by:** Div S. | Chief Marketing Officer, Small-Business (50 or fewer emp.) **Reviewed Date:** March 13, 2026 **What do you like best about NeverBounce?** The no non-sense ease of use. And the support is good as compared to competitors. **What do you dislike about NeverBounce?** Additional data for catch-alls with some tips on when to add them to the campaigns vs when not to **What problems is NeverBounce solving and how is that benefiting you?** Deliverability of my email campaigns ### 5. 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?** Very helpful for verifying emails before we upload into the CRM. **What do you dislike about NeverBounce?** It's not always one hundred percent accurate. **What problems is NeverBounce 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. ### 6. Avoid Post-Acquisition: Price Hikes and Poor Support **Rating:** 0.5/5.0 stars **Reviewed by:** Pedro G. | Chief Executive Officer, Mid-Market (51-1000 emp.) **Reviewed Date:** December 09, 2025 **What do you like best about NeverBounce?** I like that NeverBounce was simple to integrate and worked well for many years. The initial setup was very easy. **What do you dislike about NeverBounce?** 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 solving and how is that benefiting you?** We use NeverBounce to validate our emails, checking if they are valid or not. ### 7. The tool is good but there is obviously scope for improvement. **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Legal Services | Mid-Market (51-1000 emp.) **Reviewed Date:** September 22, 2025 **What do you like best about NeverBounce?** Easy to use interface and lag free. Simple to understand UI/UX . **What do you dislike about NeverBounce?** The validity of the emails IDs is a little less accurate compared to competition, **What problems is NeverBounce solving and how is that benefiting you?** Helping with the validity of the email IDs ensures that the reachout happens to the relevant people and ensures that the emails don't bounce. ### 8. High bounce rate even after verification, support completely unhelpful **Rating:** 1.0/5.0 stars **Reviewed by:** Verified User in Human Resources | Small-Business (50 or fewer emp.) **Reviewed Date:** June 05, 2025 **What do you like best about NeverBounce?** Implementation is pretty easy and they have good pricing **What do you dislike about NeverBounce?** We’ve been a NeverBounce customer for over 10 years, but I can no longer recommend their service. We used their platform to verify every email we sent—expecting, of course, that verified emails wouldn’t bounce. Despite that, we continued to see a high bounce rate, which is simply unacceptable. What’s worse, NeverBounce’s support was completely unhelpful. Responses felt AI-generated, with no real resolution offered, and we were left waiting without answers. Avoid their service. There are far better and more reliable email verification providers out there. **What problems is NeverBounce solving and how is that benefiting you?** Email verification ### 9. High bounce rate - they do not verify emails **Rating:** 0.0/5.0 stars **Reviewed by:** Ed M. | Founder, Small-Business (50 or fewer emp.) **Reviewed Date:** June 13, 2025 **What do you like best about NeverBounce?** Absolutely nothing, they didn't verify the emails - it is fraud **What do you dislike about NeverBounce?** I verified thousands of emails none of them worked if the person had left the company, the emails did not deliver and the email did not exist **What problems is NeverBounce solving and how is that benefiting you?** Absolutely zero problems, it is actually causing problems ### 10. Unresponsive customer support. They do not honor their guarantee. **Rating:** 0.0/5.0 stars **Reviewed by:** Anthony C. | Owner, Small-Business (50 or fewer emp.) **Reviewed Date:** October 22, 2024 **What do you like best about NeverBounce?** We didn't have any problems with them for the first few months. **What do you dislike about NeverBounce?** The first time we had an issue it caused a big disruption. We had a large email campaign ready to go - but it was shut down because of high bounce rates. We checked with neverbounce to ask what happened since we just cleaned the list the night before. We urgently needed to resolve the situation or we risk losing a week's worth of sending. They were slow to reply (taking 24-48 hours in between responses initially). Their responses were not helpful. And then they just stopped responding altogether. They did nothing to resolve the issue, or answer any of our questions. And they most certainly made no effort to honor their guarantee. My last message to them was that if we didn't hear back soon we were going to leave a poor review on G2 and initiate a chargeback. Suddenly they responded and said that our messages had been landing in their spam folder which is why they didn't see them. Rest assured they are on top of the matter now. But now its been nearly a week and no replies. **What problems is NeverBounce solving and how is that benefiting you?** none ## NeverBounce Integrations - [HubSpot Sales Hub](https://www.g2.com/products/hubspot-sales-hub/reviews) ## NeverBounce Features **Generative AI** - AI Text Generation - AI Text-to-Speech **Agentic AI - Email Verification** - Decision Making ## Top NeverBounce Alternatives - [ZeroBounce](https://www.g2.com/products/zerobounce/reviews) - 4.7/5.0 (1,350 reviews) - [Kickbox](https://www.g2.com/products/kickbox/reviews) - 4.5/5.0 (583 reviews) - [Reoon Email Verifier](https://www.g2.com/products/reoon-email-verifier/reviews) - 4.8/5.0 (1,012 reviews)
