One of the Top Email Verifier App

5.0 2 years ago

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I don't really like the user interface, which appeared outdated.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

5.0 5 years ago

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.

Email Validation Software: Good quality and fairly priced

3.0 6 years ago

Comments: We came to ZeroBounce after a very disappointing experience with Kickbox. Compared to Kickbox and the over-aggressive guy from the US we had to deal with, ZeroBounce has been friendly, accommodating and provides a good alternative. Just hoping they will futher develop their email scoring and become the best provider!

Pros:

Easy to use, well designed and providing a good option for email validation

Cons:

The email scoring feature which is so important to us, is still not of sufficient working quality

Fight against bad traffic

5.0 4 months ago

Comments: Overall the experience is excellent, if the price could more affordable or maybe give more email points for the price I think should be enough

Pros:

Any user with experience in sending email will understand my words below: * Bad Traffic * Bots * Bad reputation * Bad emails Thanks to zerobounces You're going to decrease bounce rate almost 0 and your ESTMP / SMTP will thank you for that. * Good communication * Good and Excellent performance API not doubt. * Good API handling, Incredible description in all JSON callback.

Cons:

The price is a little bit expensive, but I think it's worth it.

Good and cost efficient service

5.0 2 years ago

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.

Useful email validator for bounce rate reduction

5.0 2 years ago

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.

"The Best Email Validation Software"

4.0 3 years ago

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.

Keeping your Mail clean of unwanted information is possible

4.0 5 years ago

Pros:

If I had found out before that it was possible to keep my mailbox free of spam I would not have believed it, this software is quite simple, easy to use and very fast. In addition, it is not necessary to be using it all the time, since, with only authorizing it, it begins to make the cleanliness of your mail account. One of its greatest benefits is the saving of space that begins to be noticed immediately.

Cons:

One of the features that makes me doubt is the security of my information, I'm still testing its operation, but I think it's the only point that makes me doubt.

Great and Easy to Use

5.0 6 years ago

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.

ZeroBounce is the best email validation tool for us, been very useful indeed.

5.0 3 years ago

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.

Good Value Email Verification

5.0 6 years ago

Comments: Overall good. I only needed to verify one batch of emails, but the process was fairly straight forward and had the desired results. Just expect a bit of spam afterwards, but still worth the value since you can just block the spam..

Pros:

I was able to verify about 40K emails in a very short period of time. The results were separated into several categories that helped to identify what emails were not only valid but likely to have an actual customer on the other end. Absolute best thing about it was the price though. I did a bit of searching before going with ZeroBounce and this one had one of the best prices.

Cons:

This is an odd one. After verifying my emails, I started getting marketing emails from ZeroBounce. Pretty standard, I just unsubscribed and went on my way. But then the CEO or owner possibly started emailing me directly about various marketing things. I ended up having to block him so I could stop getting emails. Not that the emails were overwhelming or anything, but when you unsubscribe from a mailing list, you expect the emails to stop.

Unsurpassed software

5.0 5 years ago

Pros:

Zero Bounce is my ideal complement at work. I receive and send many emails daily with information about the services we provide in our work, as well as sending confidential information to my bosses, and reports on the development of our activities in cultural promotion; to achieve all this I use Zero Bounce as I can set filters of verified email addresses, make anti-spam filters, mail filters that enter my inbox. All these functions make it possible for me to work with a lot of security in my email. Zero bounce is wonderful software for me.

Cons:

A software that I have used at all times and I have taken advantage of each of its tools reaching the conclusion that this software is perfect for me and has no defects that make me change software. Zero Bounce is phenomenal software that fits very well in demanding work environments.

An excellent filter of spams, which keep our databases at work clean.

5.0 6 years ago

Comments: If you are looking for a program that optimizes the fucniones of your management or company, Zero Bounce must be in that software package necessary to be a successful company. An optimal mail filtering, an accurate configuration, which allows not to send unwanted emails to the main tray, easy to use and configure. I recommend this software

Pros:

In our work, we have several emails where we send information to each of the companies associated with service providers for the development of the social area. These contacts with business providers bring generic promotional mails that become spam. Zero Bounce is a great help for this type of cases, since within its benefits it allows to establish a filter for this type of spam emails, which load the database. Added to this allows to establish a more optimal organization of the emails desired by my management to work.

Cons:

We have tried several spam email filter programs with disappointing results because despite the configuration established some spam emails arrived in the main tray. However since we use zero bounce, we have not had this problem so I do not have any contras in relation to the use of this software.

Your Emails - Clean.

5.0 6 years ago

Pros:

Zero Bounce is an e-mail “cleaner”. It helped me clean out all the spams, bots and other unnecessary e-mails. The software is easy to use and understand. Once you have inputs on which type of e-mails are for keeping, the software then cleans out the inbox and other e-mails. It is amazing on how easily you can manipulate the software in order to keep the e-mails you want. It has been more than helpful since I receive more spam messages than actual e-mails. Also, Zero Bounce segregates my e-mail depending on its sender.

Cons:

Not much negative to say about Zero Bounce at this point.

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.

Great service but others are better (barely)

5.0 6 years ago

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.
