"Great Value for Pre-Send Email Validation with Better Data Visualization"
What do you like best about Kickbox?

Decreasing the number of emails with bad addresses in our org. Review collected by and hosted on G2.com.

What do you dislike about Kickbox?

I thought I was prepared to send my email, but it turns out, we still had 12 hard bounces after I ran all of out emails through Kickbox. We only have 247 contacts, and I was only emailing 80, so 12 is HUGE. On the up side, it was cheaper than Never Bounce, and I think the visualization of the data I got back was better. But there were a lot of emails that were unconfirmed. Review collected by and hosted on G2.com.

"Essential for Email Deliverability, Easy to Use"
What do you like best about Kickbox?

I use Kickbox to scan lists for deliverability before importing them into HubSpot. I appreciate that it identifies potential deliverability issues, which helps me keep my bounce rates down on my marketing emails by avoiding sending to addresses that would bounce. I find it easy to use, and I like the clear classification and explanations. Contacts are classified into different levels of riskiness regarding deliverability, and the reasons are explained, which I find helpful. Additionally, the initial setup of Kickbox was very easy. Review collected by and hosted on G2.com.

What do you dislike about Kickbox?

The integration with HubSpot is not very useful. Currently, it can pull in lists from HubSpot, but I don't need to scan these contacts, I will have done so before they entered the platform. What I would like to do is be able to send new contact lists into HubSpot from Kickbox as an import. Review collected by and hosted on G2.com.

"Effortless Email Verification, Reliable Results"
What do you like best about Kickbox?

I appreciate Kickbox's simplicity and accuracy. The interface is easy to use, and the verification results are reliable. The real-time validation is very helpful for preventing bad email entries. It's a smooth, hassle-free tool that just works. The initial setup was very easy, and everything felt intuitive, so we were up and running quickly. We use Kickbox with Salesforce and HubSpot, which helps maintain accurate records, reduce bounce rates, and improve email deliverability. Review collected by and hosted on G2.com.

What do you dislike about Kickbox?

One thing that could be improved is the consistency of the verification results. Occasionally, when I rerun the same email address, Kickbox returns different outcomes, which can make it a bit confusing. Improving result stability and accuracy would make the tool even more reliable. Review collected by and hosted on G2.com.

"Effortless Email List Clean-Up with Kickbox"
What do you like best about Kickbox?

I use Kickbox to cleanse my email lists, ensuring my newsletters are sent without interruption. It's simple to use and provides quick results, which I find incredibly valuable. With Kickbox, I've been able to increase my newsletter delivery rates and keep my system from locking up due to too many invalid address sends. I've used it for both large and smaller lists, and it's a convenient tool, especially when dealing with lists that might not have solid contact info. When I first started, I inherited a poorly maintained customer email list and Kickbox helped me quickly cleanse it, eliminating issues with account lockouts and helping me maintain a 99% delivery rate. The initial setup was very easy, and I was able to integrate it with my HubSpot database seamlessly. I also like that I can rely on it to ensure that emails reach the right recipients and maintain high delivery rates. Review collected by and hosted on G2.com.

What do you dislike about Kickbox?

I can't say I have many complaints. I didn't realize there was a whole 'Understanding Results' section and this could have been helpful to know sooner if I knew where to look. Perhaps make it easier to find on the site or as a pop-up option, like a tutorial. Review collected by and hosted on G2.com.

"Effortless Email Validation, Zero Issues in 5 Years"
What do you like best about Kickbox?

I like Kickbox for email validation, which is my primary requirement for sending bulk emails to my subscribers. I've been using Kickbox for more than five years, and it's never given me any challenges. I also found the setup quite easy; it took us less than thirty minutes to do the entire configuration, and we've been smoothly using it since then. Review collected by and hosted on G2.com.

"Easy Integration and Great at Catching Typos & Undeliverable Emails"
What do you like best about Kickbox?

It was very easy to integrate, and it does a really good job of weeding out typos and undeliverable addresses. Review collected by and hosted on G2.com.

What do you dislike about Kickbox?

The dashboard doesn't give a bunch of information. It's very simple, which is nice for a general understanding, but I would like to be able to get down and see which emails were categorized how in a given time frame. Review collected by and hosted on G2.com.

"Kickbox Restored My Deliverability and Protected My Sender Reputation"
What do you like best about Kickbox?

Kickbox helps me keep my sender reputation in good standing. Ever since Google tightened down on email security late last year, a lot of my messages started landing in spam and my deliverability tanked. After I cleaned my list and ran a warm-up sequence that only sent to deliverable contacts, things improved and felt much more stable overall. Review collected by and hosted on G2.com.

What do you dislike about Kickbox?

Nothing at this time of note. Everything has been fairly straightforward and simple. Review collected by and hosted on G2.com.

"Simplified Email Verification with Kickbox"
What do you like best about Kickbox?

I like Kickbox for its clear classification of email health, which simplifies understanding which emails can impact my deliverability rate. I appreciate the simplicity of the final result file, which groups results into four straightforward categories: Good, might be risky, bad, and don't know, without overwhelming me with too many categories. Also, the initial setup was super easy. Review collected by and hosted on G2.com.

What do you dislike about Kickbox?

I don't like that I can't directly import in the CRM. I can directly pick a segment from HubSpot and ask for email verification, but I can't do it for importing data back. I take data first in Excel then I import manually. Review collected by and hosted on G2.com.

"Simple Yet Effective Email Verification Tool"
What do you like best about Kickbox?

I like that Kickbox is a simple solution that helps us verify emails easily. It's really easy to onboard and connect, and it's not too expensive. One person was able to get onboarded in enough time. The tool provides good insights into what our average Sendek score is. The process of integrating it is quite straightforward, and the support forum is helpful. Review collected by and hosted on G2.com.

What do you dislike about Kickbox?

There isn't a simple one-off integration with Customer.io, so it took a little bit of time to integrate. I had to do a whole API integration as a nontechnical user, and as a marketer, this was a bit challenging, but not impossible. Review collected by and hosted on G2.com.

"Effortless API Integration and Intuitive Dashboard Make Email Verification a Breeze"
What do you like best about Kickbox?

I appreciate how straightforward the API integration is and how reliable the validation results have been. The response structure is clear and easy to parse, which simplifies integrating Kickbox into automated workflows for email verification. Additionally, the dashboard is intuitive and offers helpful analytics for tracking validation activity. Review collected by and hosted on G2.com.

What do you dislike about Kickbox?

The only drawback I've noticed is that SMTP verification can occasionally take longer with some domains, and there is a lack of detailed information when a request times out. Additionally, having more flexible pricing options for smaller verification batches would be beneficial. Review collected by and hosted on G2.com.
