ZeroBounce vs. Kickbox: Who’s more accurate?

Your email validation tool is only as good as it is accurate.

If you can’t trust your results or your email cleaner fails to identify what’s on your list, you can’t improve your email marketing. Let’s look at who provides the most accurate, reliable email verification experience.

Kickbox email verification accuracy

Kickbox reports that its email verification system is 99% accurate. They also claim you can expect an email bounce rate of less than 2%. However, it’s worth noting that their documentation only provides a 95% email deliverability guarantee.

How ZeroBounce’s accuracy compares to Kickbox

ZeroBounce’s email validation also offers 99% accuracy. Similarly, you can anticipate an email bounce rate of less than 2% with your newly-cleaned email list. There are no catches or other numbers you need to worry about regarding your email deliverability.

ZeroBounce supports its accuracy claim with a no-questions-asked money-back guarantee.

What types of emails does Kickbox detect?

While the pricing of any tool is important, it’s just as vital to know what your email cleaning tool provides. Not all email verification services can identify a broad range of email types.

Let’s compare what Kickbox can detect compared to ZeroBounce’s email cleaner.

Kickbox will identify a healthy number of invalid and high-risk email types to improve your email deliverability. However, ZeroBounce can accurately identify more than 30 statuses and sub-statuses of the emails on your lists.

That list includes abuse emails, repeated spam complainers, toxic domains, and other possible traps that can harm your sender reputation. Compared to Kickbox, ZeroBounce email list cleaning reports give you the most comprehensive data about who’s signing up on your forms and making it onto your email list.

ZeroBounce email verification reports offer more insights

When you scrub your list with either Kickbox or ZeroBounce’s email verifier, they can identify duplicate emails.

However, only ZeroBounce offers free, automatic deduplication to eliminate any unnecessary contacts taking up space. You won’t need to worry about risking multiple emails to the same person and racking up spam complaints or unsubscribers needlessly.

Kickbox can identify duplicate emails but leaves you to do the busy work of tidying up your data.

Kickbox also offers some light appended data, such as whether the email is role-based or on a free domain like Gmail or Hotmail.

ZeroBounce offers a more comprehensive set of appended data, including domains, usernames, IP data, name, gender, location, and mx information when available. You can clean your list and segment your subscriber data with the newfound data for better targeting and performance.

Kickbox and ZeroBounce help with email deliverability

In addition to their email verifier, both ZeroBounce and Kickbox offer additional email deliverability toolkits.

Both include:

  • Inbox placement testing
  • Blacklist monitoring
  • Email server and deliverability testing
  • DMARC monitoring

ZeroBounce and Kickbox allow you to try each tool by awarding your free account with a test for each. However, like ZeroBounce’s free email verification credits, you’ll receive one new monthly test for each email deliverability tool.

With your free credits and free deliverability toolkit, ZeroBounce can help free users gain insights about their email performance at zero cost. With Kickbox, you’ll need to subscribe to their deliverability tools to use them further.

Like email verification pricing, ZeroBounce offers more flexibility with affordable pricing and even more testing within each package.

ZeroBounce offers additional email insights and scoring

Your priority is to obtain clean emails for your email marketing.

But what if you could rapidly identify which email subscribers are the most active? What if you could reliably sort your accept-all emails so you don’t lose out on those potential sales?

Kickbox offers no such insights when you use their email verifier or deliverability tools. ZeroBounce does.

ZeroBounce offers Activity Data

Activity Data, a customer-beloved feature, gives you helpful insights into your subscribers’ overall email activity. It looks at actions such as clicks, opens, forwards, and unsubscribes that took place anywhere in the last 30 to 365 days - you set the period.

If you’ve got a particularly valuable offer and need those conversions, use Activity Data to find which valid contacts are in their inbox frequently. Segment those leads into a separate list, and watch your email marketing performance flourish.

You can also score your accept-all emails

Similarly, ZeroBounce offers accept-all or catch-all email scoring to help you get more value from those contacts.

Understandably, all email verifiers, including ZeroBounce, tag catch-all emails as “risky.” If you can’t make an informed decision, you’re better off not risking the bounce or low engagement.

Email Scoring looks at recent activity levels of your catch-all domains and grades them on a scale. High-scoring catch-alls show you higher activity levels, making them possible targets for your next campaign. It’s not guaranteed they’ll get your email, but it allows you to make informed decisions. Every email lead costs money, after all.

ZeroBounce offers mobile email validation

Another benefit ZeroBounce provides versus Kickbox is email verification for mobile devices.

You can take advantage of ZeroBounce’s email validation and all the other substantial benefits listed on this page from anywhere in the world. By comparison, Kickbox and other major competitors lag behind with a strictly desktop experience.

ZeroBounce customer support outpaces Kickbox

No matter how savvy you are with emails and technology, it’s good to know you have support when needed.

Kickbox lets you contact them by phone, email, or live chat. Inquiries via live chat typically take a few hours to receive a response.

ZeroBounce understands that urgent problems happen and you need help fast. That’s why they offer 24/7 support via live chat and phone 365 days a year. That includes weekends and holidays for your convenience. We secretly tested our average response time, and our email experts reached out in less than 12 seconds.

If you’re more of a self-starter, ZeroBounce also offers comprehensive, up-to-date documentation for every tool and service on the platform.

Frequently Asked Questions

ZeroBounce offers more affordable pricing than Kickbox with Pay-As-You-Go and subscription plans. Enjoy guaranteed 99% email verification accuracy with a plan that makes sense for your brand. You also get 100 free verification credits and one test for each deliverability tool monthly at no extra cost.

ZeroBounce and Kickbox advertise a 99% accuracy rating for their email validators. However, only ZeroBounce offers a money-back guarantee. Kickbox lists a 95% email deliverability guarantee, which differs from the accuracy rating on their website.

Verifying the emails on your list helps you reduce your email bounce rate and improve your email deliverability. When you’re able to deliver more emails, you can gain more accurate insights regarding your performance and drive improvements that boost your email marketing ROI.

You should clean emails at least once per quarter (every three months). All you need to do is upload your list to an email verifier and wait for your results. Then, import your new list back into your email database. You can also keep emails clean automatically by using an email verification API.

Real-time email validation automatically determines whether an email is valid at the time of signup. When a user enters an email into one of your signup forms, the email validator API detects it and either blocks or accepts it based on the result. This helps keep your email list clean for longer.
