Charles
One of the Top Email Verifier App
Pros:
There are several aspects that I appreciate about this service. Firstly, it is exceptionally precise, and I have not encountered any problems with email bounces. Secondly, it is user-friendly, where you simply upload your email target file, receive an analysis, and new lists divided into good versus bad email addresses.
Cons:
I don't really like the user interface, which appeared outdated. Furthermore, the process may seem sluggish. Although the price is slightly high, there isn't much to criticize since the service delivers a satisfactory output, which is an essential requirement.
Alternatives Considered: Clearout and Bounceless

Best Email Validation Application
Comments: Our overall experience with ZeroBounce was great. They gave us everything we needed when we were choosing which vendor we wanted to go with and were not overly pushy on the sales side - not to mention they have a great product. The documentation they provided free on their website actually helped us understand things that had nothing to do with their software but just email marketing in general, so that was really great.
Pros:
We chose ZeroBounce after doing testing of multiple email verification companies for a client that was looking to improve bounce rates. The reason we chose ZeroBounce was because they had some of the most accurate results and were quick to offer special rates for our company. Personally, I really appreciated that their sales reps were not overly pushy and really gave us space when we were making our decisions, unlike some of the other ones. They have really good documentation on their website which educates people not only on their own software, but only email marketing in general. They also offer free name appending with their validation services. Lastly, they had a few special features that I had not seen offered on other email validation sites and offered 1,000+ free credits to get started.
Cons:
The only con we found was that the software can run a little slow at times but this is acceptable because from the testing we did, it showed that even though the service took a bit longer to run - the results were better. To me, this just says that the reason it takes longer is because it is going through more extensive validations.
Alternatives Considered: XVerify and QuickEmailVerification
Reasons for Choosing ZeroBounce: We were looking for better email validation results and real-time verification for lower prices.
Switched From: Melissa Data Quality Suite
Reasons for Switching to ZeroBounce: Price and testing results combined were more favorable.

Vijendr
An average email verification tool.
Comments: My experience was neither very good nor very bad. It is an average software.
Pros:
The user interface of ZeroBounce is quite good. A normal user can easily use its functionality.
Cons:
I found difficulties during validation of large data sheets. It took lot of time and sometimes I used to redo the process 2-3 times to get the complete results. I also didn't find its accuracy as per my requirements.

Helped me reduce email bounces
Comments: excellet.
Pros:
It has helped me in reducing the number of emails per campaign that bounce. Earlier we were having high bounce rate & a famous blogger suggested me to try zerobounce. After using it for few months I'm very happy with it :D

I wish they tell if my emails are delivering in inbox or spam.

Good and cost efficient service
Comments: Not a single issue in years, and when we detected a "problem", they solved it ASAP and keep us informed every time they could tell something.
Pros:
Easy API, simple and straightforward, in fact. Implementation was fast and customer support is nothing but clean and efficient.
Cons:
So far, we have nothing wrong. The issue we had with ZB we have it with other services, too, so it was not in fact ZB's fault.
Alternatives Considered: SparkPost and EmailOversight
Reasons for Switching to ZeroBounce: We use SparkPost for other goals, and have been using EO, too.

Dilay
Useful email validator for bounce rate reduction
Comments: ZeroBounce is definitely helpful for increasing the successful delivery rates of our online email marketing campaigns.
Pros:
ZeroBounce helps us to validate the user emails that we store in our database before launching an online email marketing campaign. This way we reduce the ratio of undelivered or bounced emails in our bulk email marketing campaigns.
Cons:
It was pretty time consuming to integrate ZeroBounce to our internal system. We were quite dependent to the guidiance of the support team.

Noli
ZeroBounce Personal Review
Pros:
I liked how simple ZeroBounce was to use. I was up and running in minutes because it was so simple. It was also very dependable, as none of my emails were lost. Overall, I strongly recommend ZeroBounce to anyone looking for a reliable and user-friendly email validation service.
Cons:
I didn't like how ZeroBounce doesn't allow you to automatically remove bounced emails from your list. I discovered that I had to manually go through the list and delete them, which took a considerable amount of time and effort.

Hi, Noli Thank you for taking the time to review us! We love to hear that you found it so easy to use ZeroBounce. As for your results, you should have a dedicated file for all the valid emails and individual files for each status code. So you don't have to remove bounces manually. We hope this helps. Thank you again for sharing your feedback!

Bala
"The Best Email Validation Software"
Comments: Setup was quick, API usage was simple, extensive information was returned, and the support crew was very efficient and responsive. After evaluating four other options, we decided on ZeroBounce and have not been disappointed.
Pros:
We chose ZeroBounce after evaluating a number of email verification services for a client who wanted to reduce bounce rates. We chose ZeroBounce because they provided some of the most accurate results and were fast to offer our firm exceptional discounts. Unlike some of the others, I loved how their sales staff were not excessively pushy and truly gave us room when we were making our decisions. They have excellent documentation on their website that educates users not only about their programme, but also about email marketing in general. With their validation services, they also provide free name appending. Finally, they offered a few unique features that I hadn't seen on other email validation services, as well as 1,000+ free credits to begin started.
Cons:
The only disadvantage we discovered was that the programme can be a little sluggish at times, but this is tolerable because our testing revealed that even though the service took a little longer to run, the outcomes were superior. To me, this simply means that it takes longer since it is subjected to more thorough validations.

Max
Great and Easy to Use
Comments: Overall, great. Love using it and highly recommended.
Pros:
I've found ZeroBounce to be the best and most accurate email verification service, for both single-email validation and list validation. And very cost-effective too. I use it daily for my company to vet emails we generate from prospective clients, and prior to sending out mailing lists to ensure our lists have as high deliverability as possible (as most services require these days due to anti-spam laws). I like how they give a breakdown on each email address and their status.
Cons:
Some of the nomenclature/descriptors for the emails are hard to understand. For example "Spam Trap" or "Catch-All". It would be helpful if ZeroBounce provided more information on what those various categories mean and how to use them (or not). The current information provided is a little sparse and leaves something to be desired.

Shayan
ZeroBounce is the best email validation tool for us, been very useful indeed.
Pros:
I've been using the platform for a very long time and its been excellent. They have a 98% accuracy when it comes to validation which is always comforting. The validation process is just effortless, you simply upload a file and click a button. What I like the most is that when you download the results after the validation check, the downloaded file splits the results into different folders so for example valid, invalid, donotmail, spamtrap and so on.
Cons:
Honestly speaking, I do not have anything which I dislike about the platform. I've always had a good experience with the platform so no issues with customer service or any problems when using the platform. The platform does exactly what its supposed to and it does it very well every single time with no issues for me.

A great way to make sure that sent newsletters are guarded and non-toxic
Pros:
I was on the market for an email protect kind of software and I came across ZeroBounce. Its appraisal rate is high. Upon using it, it never once disappointed me with its features. Server detection of received emails is possible, preventing fraud. Removes spam, temporary addresses and toxic domains. It is an install and run kind of program which means once you install it, it will run silently in the background with little to no manipulation at all. It is amazing and very helpful. I would highly recommend this if you are dealing with many emails and you are trying to send newsletters or any type of emails as well.
Cons:
Filters are rarely not accurate. There are a few spams that escape and find their way into your inbox.

Zero Worries With My Email Marketing!
Comments: zerobounce has helped me enjoy zero worries with all my email marketing campaigns.
Pros:
Every online business owner knows the importance of email marketing, but email marketing comes with a lot of hurdles. You have to struggle with maintaining the reputation of your IP, maintain a low spam score, ensure your email delivers to the inbox of your subscribers, and lots more. One could easily get overwhelmed by these, luckily zerobounce is here to the rescue. With zerobounce I can filter out emails that could hurt my business, remove invalid emails, remove emails that increases my spam score and lots more. In short, zerobounce has helped me enjoy zero worries with all my email marketing campaigns.
Cons:
Nothing much really, zerobounce has been a great tool for my business. I only had one encounter of slow response from the customer service, which I understood anyways.

Has become my go-to email list scrubber
Comments: My overall experience is a series of clean, fast, and simple transactions where you pay a good price and get what you expect! What's not to like?
Pros:
It's very hard to talk about quality... to do so I suppose I could rig an experiment by submitting my confirmed customers' lists to multiple providers and comparing their results... but that's time and money I don't have to spend on intellectual curiosity. SO, basically, our only real comparison points remaining are cost and turnaround time. And ZeroBounce excels at both! You upload a file. You wait for less-time-than-you'd-expect, and you download a folder with several subfiles. This is your content segragated into deliverable, undeliverable, email traps, and 'accepts all'. Be smart and just send to the deliverable segment. If you're using a backup or temporary email provider because you suspect the list is bad or you got a groupon or something then you can include the "accepts" all segment too.
Cons:
the only quibble I have is the somewhat excessive security process to ensure that only you are receiving your scrubbed lists. What can I say? I'm more of a reckless wild child and if the Russians are tapping me to get me email list, so be it. (Maybe they'll have better luck? )

The mail of the company totally clean thanks to this program
Comments: Thanks to this software my company acquires more versatility for the reception of information by the clients, it allows me to create spam filters necessary to not fill my emails
Pros:
Product of the offers presented by our company, many of our clients add us to spam emails that send their emails to the database of our organization. This program is very useful for us because it allows us to place really effective spam filters that allow us to have our trays operational to serve our customers.
Cons:
Sometimes the filters must be very specific, if the information leaks to the company's emails, degenerating the management of our organization

Comments: We are using AWS Simple Email Service for sending emails from our cloud service offering and selected Zerobounce in order to reduce our bounce rate. With Zerobounce we are able to maintain a good bounce rate in AWS by not sending emails that we know will bounce to invalid email addresses.
Pros:
-support response time is very quick and resolution time quick as well -easy to integrate into our typescript nodeJS environment -love the new dashboard to view api usage -gdpr compliance right off the bat
Cons:
-not much that I didn't like, it was a bit tricky to determine from the possible errors returned which ones should be considered a pass or fail.

It all started with the free trial
Pros:
Well like in the title, you just need to take a look at this tool for free. After I tried, it was easy to pay for it when the trial was over. Great email manager, to just know I´ll be seeing exactly what I need to see when it comes to work: it´s priceless. Great app, and this includes great costumer service. Easy to customize the spam filters and just easy to always be in touch with your clients. Thank you.
Cons:
It can get a little messy with a lot to do when settings things up for the first time. Can take some time to go through that stage, but once is up and running, it works smoothly.

Great service but others are better (barely)
Comments: Overall experience was good. I would recommend ZeroBounce as the second best email validation service and the easiest to use. Price was very competitive, but ZeroBounce raised prices in the middle of my usage. Fortunately, I was grandfathered in, but the service we ended up going with (that had better customer support) actually ended up being cheaper when scaling.
Pros:
ZeroBounce is quick to learn, easy to use, and also has reports showing the breakdown of results. Compared to other services, it was better at sorting greylisted emails and was "better safe than sorry" with do not sends.
Cons:
The customer service could have been better. When both my coworker and I reached out about HIPAA compliance, we received different answers. The customer service rep helping me would not answer my question, but kept repeating that ZeroBounce was compliant in other ways. The rep helping my coworker told him no straight up. Finally another rep reached out to my coworker and revealed that those helping us were wrong. When I tried again to reach out to another service rep about this, I received no answer.

Great way to ensure customers get your emails!
Comments: My emails get through to clients with zero bouncing, true to the name.
Pros:
As with any business, emails can mean leads. But leads won't happen if your emails are sent to spam by rigorous spam filters! ZeroBounce ensures that that doesn't happen. It also helps protect me from spam and other such issues on my end. Plus, it has helped me rise in my search results on Google. I think this is because it allows me to get through to people with less email bouncing.
Cons:
It can be a bit complicated to learn this application, especially figuring out the filter settings. But overall, I have had no problems with it.
