Pretty much everything other than their pricing. They have the best results in the industry. They detect the disposable and Catch-all to perfection

Nothing other than the pricing. I hope they will offer some better pricing. Everything else is top-notch already.

If a competitively-priced SaaS product does a job quickly and produces great results, it's a great solution. That's exactly what NeverBounce is for my agency. Their product is so good that they give me virtually no reason to consider looking somewhere else.

NeverBounce is an extremely fast and thorough email verification/list cleanse tool. I've processed varying data sets (as many as 500,000 emails and as few as 500) at a time and have consistently been surprised by the speed at which NeverBounce can clean them. (For the larger list, it only took a couple of hours to complete. I can't guarantee everyone will get the same results, but I was blown away at how fast it worked through that list.) NeverBounce has also produced quality results for me again and again, which makes the speed factor I mentioned that much more impressive. While it can't completely eliminate your email bounces (no tool can; list hygiene is only one of dozens of factors that contribute to your bounces), NeverBounce will certainly reduce your bounce rates significantly. What I also appreciate is the option to extract whatever list segment you need and identify over 25 advanced data points that were detected in the cleanse. This means you can quickly identify free email hosts, role accounts, data with incorrect syntax, valid DNS/MX records, etc. All super useful stuff. You can slice and dice the data any way you want, basically. Last, NeverBounce provides a super clean, uncomplicated user interface which I appreciate. It's a very intuitive tool that is very easy to pick up and learn, and also easy to teach someone else how to use. It would be very easy to teach an intern or a VA to upload, process, read, and extract data from NeverBounce if needed.

I wish NeverBounce gave some deeper insight into exactly why an email was pulled/filtered/flagged in the cleansing process. They place emails into general categories (Valid, Accept All (Unverifiable), Unknown, Disposable, and Invalid) which is nice enough, but I wish they provided more granular details at the individual email level. I had a situation once where a client of mine inquired about why a specific email in their list was removed and I wish I had something more specific explanation to point them toward.

When it works, it generally works well, but the lack of support means we're looking for an alternative that is more stable and better supported.

When the software works well, it is very useful and helps us to make better use of our MA solutions as well as maintain data on an ongoing basis.

The support is terrible. Known issues are not proactively reported which caused us to inaccurately tag and email thousands of contacts in the summer of 2021 (unacceptable). When we've had support questions, we message support and then wait days for a response via email. Troubleshooting articles are basically non-existent.

We have been using NeverBounce to clean the email list we get from Google Forms for our Newsletter subscribers. We moved from another tool since we were getting a high bounce rate. With NB, it decreased.

No complains so far. The customer service can be a bit slow if you have any questions even if you are a paid user though.

I had the chance to use this software for about 6 months and the result they had provided is wonderful and accurate. This popular tool in the market as well as good service.

NeverBounce pricing is a little bit higher and they should work on time-consuming verifying the list.
