Kickbox allows us to be confident in our data, it seamlessly integrates with HubSpot, giving us a high level of performance, knowing any comms we are sending are going to highly engaged, real contacts - the price impact is so small for the impact it has on the business Review collected by and hosted on G2.com.

I find Kickbox pretty easy to use. It doesn't have any unnecessary fluff, which I appreciate because I don't have time to deal with complicated websites. The API is good, making the entire process straightforward. The initial setup was also easy, which was a relief. Review collected by and hosted on G2.com.

Maybe a pre-analysis or something like that to stop me wasting all my credits. It says this is a high risk one or a low risk one or something like that. Review collected by and hosted on G2.com.

I didn't really have any negative experiences or issues. Review collected by and hosted on G2.com.

It was simple to use, upload a list, get it back sorted into deliverable, risky and undeliverable. No setup or tech knowledge needed. So easy to drop a csv file in and get a clear result back is exactly what I needed. Review collected by and hosted on G2.com.

The turn around time on larger list verifications can be slower, when waiting for initial approval from the verification team. Review collected by and hosted on G2.com.

I like how fast and simple Kickbox is. I use its email verification, and it’s great because it’s easy to use. I like how well the whole process flowed, and it was very easy to initially onboard. Review collected by and hosted on G2.com.

I think Kickbox could move into phone numbers too. Verifying whether numbers are connected to someone or disconnected would be helpful, similar to email verification. Review collected by and hosted on G2.com.

Being able to check if a user is using a real email address that is deliverable and also its great for us to identify if somebody is trying to register on our site using a throw away email address. It is also VERY simple to set up. We also find it good value for money. Review collected by and hosted on G2.com.

nothing we find the service perfect for our needs and response times on the API are already good. Review collected by and hosted on G2.com.

VERY easy to use, and easy API to work with. The Sendex Score is a great feature to keep you apprised of your sending risks...overall great solution. Review collected by and hosted on G2.com.

Can get pricey...but still sits in the middle range amongst competitors. Review collected by and hosted on G2.com.

Nothing much, everything is perfect now. Review collected by and hosted on G2.com.

I like that it's simple, straightforward, and effective. When I need to verify an email list, Kickbox helps me do so easily and quickly. Additionally, Kickbox provides a report for every email list that I verify, which is very useful both for me and for communicating results to clients. They make email verification basically frictionless, and since Kickbox offers easy-to-read/understand reports, it's easier to communicate results and show value to my clients. Another thing I really like is their variety of knowledgebase articles that are easy to find and explain email verification in very simple terms. This helps answer my questions and makes it easy to answer my clients' questions. I also used Kickbox's integration with HubSpot, which streamlined the process of verifying lists directly from HubSpot in Kickbox and then quickly getting the verified lists added back to HubSpot. The initial setup was very easy. All I needed to do was create an account, add a payment method, and then I was ready to use Kickbox. Review collected by and hosted on G2.com.

For the most part, I haven't had any problems with Kickbox. However, one small nitpick I have is how 'Unknowns' are handled. When you verify an email list, it's possible that Kickbox will be unable to get a valid response from some recipients' mail servers. When this happens, they mark the email as 'Unknown' because they weren't able to verify it. While it's nice that Kickbox will let you re-verify these 'Unknown' email addresses for free, re-verifying these email addresses creates a second, separate report. For a recent verification job, I was initially faced with ~1,300 'Unknowns,' which was a good chunk of my list. So, I had to re-verify these ~1,300 emails several times in order to verify most of them, which led to me having 7 different reports/results for one list. Instead of being able to download all of the results together, I had to download files separately and combine them manually. Perhaps there is a good reason why Kickbox handles re-verifying 'Unknowns' this way, but I find it to add a bit of friction to my job. Review collected by and hosted on G2.com.
