NeverBounce

Pros

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.

Cons

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.

Pros

It is super simple to upload and accurately clean a list of email subscribers. Just the nature of the business is that, over time emails get changed or are dead, and we cannot afford to have too many bounces through our bulk email service or we will get flagged, or even banned. We don't mail super often so it helps to from time to time verify the email BEFORE we send, and this is pretty close to 100% accurate in doing that for us at a reasonable price.

Cons

I found it rather hard to integrate it with our CRM, hubspot. It does have an integration but the process and method given to integrate it was rather circular without giving clear, step by step from start to finish. I discussed this with product support. they are very good and helpful and it was worked out. Not sure if they have updated their online help resources to deal with that.

Pros

The best about NeverBounce is their user-interface. This tool is very simple and easy to use. We can upload our list and analyze percentage of invalid contacts and then go for paid plan.

Cons

Since we are paying to identify email address valid or not why I am getting more unverified or uncertain email address. They must improve overall result identifying email address either valid or invalid.

Pros

The email verification results was turned around in less than 15 minutes. Pretty fast seeing as I had a little over 20,000 emails. The integration with ActiveCampaign saved us a lot of time from having to export and then import lists. I was able to easily transfer our contact list with a simple integration and start the verification process.

Cons

The accuracy was okay. Despite running email addresses through NeverBounce, when I sent out email campaigns, I would still get reports that some addresses bounced or were not valid.

Pros

They are industry best for list validation

Cons

Very expensive to buy credits. They shouls reduce price
