NeverBounce Reviews & Product Details

When we started using them 6 years ago, we liked their service. Affordable and only occasional bugs. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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.

Pay as you go pricing is reasonable, interface easy to use Review collected by and hosted on G2.com.

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 Review collected by and hosted on G2.com.

I like that NeverBounce was simple to integrate and worked well for many years. The initial setup was very easy. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

Easy to use interface and lag free. Simple to understand UI/UX . Review collected by and hosted on G2.com.

The validity of the emails IDs is a little less accurate compared to competition, Review collected by and hosted on G2.com.

Implementation is pretty easy and they have good pricing Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

Absolutely nothing, they didn't verify the emails - it is fraud Review collected by and hosted on G2.com.

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 Review collected by and hosted on G2.com.

We didn't have any problems with them for the first few months. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

Would not recommend, especially for businesses that need reliable and timely services. Review collected by and hosted on G2.com.

We chose NeverBounce to streamline our email verification process, but it has been nothing but a disappointment. After making the payment, the credits were not added to our account. The portal even shows a refund, but despite multiple follow-ups, no refund has been processed, and we received no response from their customer support team.

This lack of responsiveness and failure to resolve such a basic issue has impacted our business operations. I expected much better from a service like NeverBounce, but this experience has left us reconsidering our choice.

Would not recommend. Review collected by and hosted on G2.com.

NeverBounce is the best because it’s quick, accurate, and easy to use. We can customize email verification with tailored integration options. It integrates smoothly with popular platforms, keeps email lists clean, and is affordable for businesses of all sizes and its bulk verification makes managing large lists hassle-free, which really helps with deliverability.

NeverBounce is effective but can get costly for larger lists and also some integrations take extra setup, and it could benefit from more in-depth analytics. But overall not much dislike about NeverBounce. Review collected by and hosted on G2.com.
