Efficient Email Validation
Comments: It is a great experience to integrate the ZeroBounce APIs with other CRM solutions.
Pros:
a. Email validation without any delay and accurate information. b. Emails are validated at a high frequency without any downtime. c. Credit consumption methodology is flexible according to business perspective d. Able to add multiple checks and validation using the user-friendly UI. e. Great customer support while stuck with an issue related to API schema. f. Easy to integrate with all APIs, with other app integration easy to implement.
Cons:
a. Need to increase the bulk email validation limit. Currently, the limit is 100, so we can only validate 100 emails in bulk at a time. b. Need to increase the limit for making API calls per minute, especially when working with large data volumes, as we need to adjust waiting times accordingly.

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.

Fight against bad traffic
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.

ZB Support Experience
Comments: I was completely amazed by the level of assistance provided by the customer chat support. I think I'm so pleased because the answers I was hoping for were not only provided but exceeded my expectations. Our conversation was quite lengthy because I had some very specific questions that required detailed answers. The representative even shared articles with me to refer back to and sent links to guide me through the necessary steps on the webpage.
Pros:
Chat Support -I was fortunate to have a patient support representative who didn't rush our conversation, even when there were delays in my responses. I received thorough answers and left fully satisfied. KB (Knowledge Base): -My interaction with Netflix's KB greatly assisted me in selecting appropriate keywords. Netflix boasts the most user-friendly KB interface, with ZeroBounce as a close contender. Navigating and searching for articles to address inquiries is a breeze. I love that it includes screenshots and videos, which helps in following the instructions as easily as possible. UI (User Interface): -The UI is intuitive, making it effortless to comprehend its functions and follow instructions. Its visually appealing design is exactly what I seek in a product.
Cons:
I am a new user, and right now it serving me with its purpose. I'm not very tech-savvy, so all that technical jargon doesn't really resonate with me as much as it might with others.

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

"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.

Keeping your Mail clean of unwanted information is possible
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.

useful product for email validation and email filtering activities
Comments: For all size companies, a very useful software to carry out email marketing solution by identifying email lists and spam domains. Clean a database from inactive email addresses and improves validation and inbox placement scores. With a suitable subscription price, the software will increase the effectiveness of customization.
Pros:
1) Very productive and effective integration with alternative Softwares such as Goggle sheets, Asana, Autopilot due to my work experience. 2) The filtering feature allows you to obtain the updated email without spams or bugs which is effective to keep customers' satisfaction high and not waste time on workflow. 3) A well-constructed security system lets you not to be worried about data privacy and anonymity of information on emails.
Cons:
1) Whether the processor of your computer is not that much strong at office, the software can work slowly. However, if you keep your device up to date, then I believe there should not be a problem. 2) There are some limitations concerned with a free trial version: a) only 5 free email sending option in a day. As a result, another colleague uses 5 free email, then you wont have the same option; b) There is only one chance to create one account with the name of the company. In free trial version, it is limited, maybe it is different in a paid version.

Comments: Zero Bounce customer service is one of it's kind and has helped my emails get opened with over 80%/100 as compared to before that I hadly get a 25% open rate.

Zero Bounce helps you verify valid emails in your list to avoid bounces when you send your emails in email campaigns. It assists you in separating the bad ones from the good ones and allowing you to import them separately to your pc before using them.

Your Emails - Clean.
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.
