Kickbox or ZeroBounce? It seems hard to choose. Both email validators have gained market recognition, so you may be on the fence about which one is best.

However, if you look at the features and tools they offer, you get more clarity to help you make the best choice.

Using information available on the Kickbox website and documentation section, we wanted to see how these two email verifiers compare.

Read on to see what we found.

ZeroBounce vs. Kickbox: 99% accuracy vs. 95% deliverability

Let’s start with accuracy, an aspect you should always keep in mind when choosing an email validation service. ZeroBounce cleans email lists with 99% accuracy – and backs it up with a guarantee.

How does Kickbox compare?

The company doesn’t state its services’ accuracy but guarantees that 95% of your emails will be deliverable.

Removing duplicates and adding data to your email list

There are four types of risky email addresses that both ZeroBounce and Kickbox can detect:

• invalid

• spam traps

• disposable

• and catch-all

Abuse emails – belonging to users who could flag you as Spam – are not on Kickbox’s list. ZeroBounce, on the other hand, has an excellent track record of detecting known complainers via both bulk and real-time email verification.

Now, let’s look at a few other features that set the two email checkers apart. For instance, the removal of duplicate email addresses. Keeping duplicate contacts in your list is costly and unproductive. ZeroBounce not only detects them automatically but it does so for free.

Does Kickbox do the same? The company does not address the removal of duplicate emails on its website.

Another aspect worth mentioning is data appending. ZeroBounce validates your email list but that’s not all: the service also enhances it with additional information – such as gender, name, location, and IP info (where available). And again, it does this at no extra cost to you. Kickbox does not mention such additional services on its platform.

Some important features ZeroBounce and Kickbox have in common:

• Both email validators give you 100 free email verifications when you create an account. Unlike Kickbox, ZeroBounce replenishes your account with 100 credits every month

• Both ZeroBounce and Kickbox provide a deliverability toolkit. It includes inbox placement testing, blacklist monitoring, and DMARC monitoring. Each company gives you one free test when you create an account – but ZeroBounce offers a free test for each tool every month

A ZeroBounce feature you won’t find at Kickbox

What if you could know who your most active subscribers are? People who check their emails a lot, so you have a higher chance of reaching them in their inbox – and converting them?

With ZeroBounce, you can. Activity Data, a feature much beloved by our customers, gives you helpful insights into your subscribers’ overall email activity. It looks at actions such as clicks, opens, forwards and unsubscribes, then places them in a timeframe of up to a year prior.

You can find out, for instance, if a certain prospect you’re about to reach out to with an offer has checked their email lately. Then, you can segment those active leads and target them with a personalized campaign to boost your sales.

Kickbox does not offer such a tool, but instead, provides you with free 30-minute email deliverability consultations.

What if you want to get in touch with someone from ZeroBounce?

You can do that at any time and connect with one of our email experts in less than 12 seconds – we secretly tested our team’s average response time. Also, we guarantee 24/7 support for everyone who visits, customer or not.

That’s not the case with Kickbox: the company does not provide round-the-clock support.
