Validation accuracy comparison
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.
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.
Better email insights
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.

Any Yahoo or AOL email lead on your list has the risk of being “disabled”.
Verify+ from ZeroBounceⓘ is a free addition to email validationⓘ that identifies “disabled” Yahoo and AOL email addresses.
By opting into Verify+, ZeroBounce will check for bounces by sending a message to the address. There’s no risk to your company or domain, and ZeroBounce handles the entire sending and verification process.
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.
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.
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.
