Email verification tools such as Kickbox and ZeroBounce help users identify and validate invalid email addresses, preventing them from being included in email accounts and contact lists.

Email professionals can increase the size of their email lists and further customize their programs by configuring their email verification software.

Using an email checker tool can be confusing, as it is complicated and takes some time and effort to learn.

We are here to fairly compare and contrast each item’s strengths and weak points so that it will be easier to determine what applies in practice. Let’s check out round two.

What is Kickbox?

validate email list

Kickbox is one of the fastest-growing companies in the industry of email authentication, it’s a well-established business that comes with many features for clients in the industry’s numerous customers.

They have recently introduced a new API connection technology that allows users to verify their email addresses directly from their websites. They have also provided their clients with a well-maintained API dashboard where they see their quantitative and qualitative data about their progress.

Their technology is useful in determining whether you should e-mail your catch-all email address, but utilizing their AI to send emails is very risky. By rating, you can determine whether to email each catch-all address.

This capability permits you to evaluate the likelihood of an upcoming communication campaign’s success, even before it runs. You can also gauge your chances of a campaign possibly going to spam.

Among the principal drawbacks of Kickbox is the higher charges compared to many competing businesses offering anti-spam services, like Email List Validation & Debounce. Kickbox costs $60 per 10,000 email validation, whereas several rivals charge $20 to $30 per 10,000 emails.

If you’re thinking about checking your checklist, but are slightly anxious about the security of your personal information, it may be hard to do a search for a reputable email list checker that respects privacy. But by using Kickbox, you can easily dismiss this concern.

They are Swiss-EU Data Foundation-certified vendors. This is not something that happens often within the email picture firm, as they only obtain this certification a few vendors can manage.

Kickbox is exclusive in that it provides in-depth information with speedy email confirmation for people interested in reviewing their information.


Great accuracy

The accuracy of Kickbox’s 99% rate is considerable for companies looking for quick, dependable ways to verify the email addresses of their readers and subscribers.

This strengthens the credibility of a firm, since it illustrates to customers, contributors, and affiliates that they’ll get the correct responses when they get in touch with the company.

Added security

When assessing the reputation of an email verification provider, many individuals commonly ask me about their own personal data security approach.

If you want to share your list of customers with a company, you may feel like you’ve got some information you’re uncomfortable with going to a third party.

When choosing an e-mail verification tool, it’s crucial to find out that it does not feature any dangers to your information, since it protects it at amazing levels by way of its high-level encryption and other security measures.

Furthermore, it stores your information for 30 days after you send it.

Excellent scoring system

Kickbox recently announced the creation of an AI technology that provides seekers a way to provide their email addresses and choose a short numeric score from 0 to 10, with the final result of 10 being the highest possible.

As a number between zero and 10, 10 is understood to be the most cost-efficient score, while zero is the least victorious. This allows for easy identification and evaluation of marketing leads and where they are in their buyer journey.

Outstanding support

The Kickbox support team is responsive, and their customer service representatives can be contacted in a variety of ways, including by phone, email, chat, and ticketing. Chat support is also available 24 hours a day, and call limitations to vary according to the call. Also, the support of the company is second to none, and the overall reliability standard is exemplary.

App Integrations

Kickbox can be integrated with nearly all of the leading email marketing tools. This freedom means you can quickly add your email list from different email service providers to Kickbox that you use. That gives you the power to easily access your lists from a single ESP.


Verification Time

We were somewhat disappointed to see that our company performs below average when handling definitely worthies of the instantaneous sorted out.

High Priced

Kickbox is one of the more competitive mailing list validation services around. It charges $80 for just 10,000 email validations, making it extremely expensive compared to the competition such as Email List Validation.

What is ZeroBounce?

ZeroBounce is a popular bulk mailing list cleaning service provider. It works with any email address you’re sending. Pay $65 to acquire 10,000 addresses.

ZeroBounce maintains an advantage over other email validation service suppliers due to their advanced compatibility with email marketing platforms and CRM systems. Their tools serve as complete email list validation solutions for many businesses and a number of government agencies.

ZeroBounce has worked with many different world-renowned businesses, including Uber, Indeed, Dell, and more. Per this company, ZeroBounce might serve as an ideal pick for anyone who needs to immediately cleanse many email addresses while maintaining a reasonable expense.

Let’s identify the two recognized sides of the tool that you need to know about.


Turnaround Time

The expected turnaround time for a list of 10,000 email addresses to be examined is approximately 498 minutes. What differentiates ZeroBounce from comparable services is that seeking only 200 minutes to check over 10,000 email addresses.

Having a high level of functionality and the skill to create rapid outcomes, we can verify that Zerobounce is one of the fastest email verification services available on the market.

App Integrations

We have previously mentioned that ZeroBounce has made a fantastic interface with more than 46 built-in applications such as high-profile email clients and marketing software. This combination places ZeroBounce ahead of its competitors.

API integration

ZeroBounce integrates an API to incorporate the confirmation of email addresses directly from various websites, landing pages, or mobile apps.


Verification Accuracy

Regarding accuracy, ZeroBounce is known to have less than optimal accuracy in many situations, which can lead to some consumers being unhappy with low rates of accuracy.

Based on the suggestions of many customers, gathering contact information through email lists does not satisfy their expectations and frequently leads to low ratings. For this reason, those spam reports do not help ZeroBounce any more than anything else.

ZeroBounce Pricing

ZeroBounce has many different pricing tiers and plans as well as free and premium alternative choices. You’ll be able to receive between 100 and 40 billion email addresses with the free plan. The more expensive plans offer more functionality and require greater confirmation of email addresses. You can sign up on their website for all their pricing, features, and choices.
