ZoomInfo is quick to make promises and…

ZoomInfo is quick to make promises and state how they can turn your business around because they have a product that no body else has and how their system is the greatest. It’s not and their customer service is horrible.

1.) The information lacks what a lot of people need and they don’t tell you from the start that theirs a fault in their system. The sales team does a good job of hiding that. The fault is that it doesn’t correctly find people. My information was linked to another business, numbers were 10x the amount we generate, and the topics that “customers” are looking for doesn’t mean they’re actually looking for it.

2.) when I first had a meeting with them, I told them that this was a sink or swim and then if we didn’t get results that were probably closing the doors. They stated how they guarantee us we would be having results. So we ran three months and maximize our chances. We did cold calls, cold emails, and beat the pavement with these “leads”. Not one account in three months. At the end of the first quarter we stopped using the product and we told them that we wanted to cancel because we were gonna have to close our doors. They said sucks to you signed a contract you owe us our money. Even though during our meetings and emails, it was explicitly told to them that we were gonna go out of business. They were so confident that they wanted to continue. Now all they say is well we sent a request, but we suggest that you catch up your balance so we have a better chance of canceling. Well, it’s already been three months I’m not using the product and they just added the third quarter to the invoice. To them they don’t care it’s as easy as paying it because money comes from thin air.

3.) prior to stop using services, we gave them a heads up that we were going to stop using the product because we didn’t have any results and of course they said hey we can help you do some training watch these videos and what not. I tried that stuff. I was even on a zoom call with two of their staff members who guaranteed me they give me contact information to a client and they fail to do that and I haven’t heard from them since.

4.) here’s what they don’t tell you, eventually while using their product you’re gonna get labeled as a spam user if you use too many of the contacts.

5.) after reading reviews, I wish I would’ve started here. I’m very disappointed in the experience and I’m very disappointed in the manipulation of the business.

Overall, it would be my recommendation not to use their service. I have had a couple other companies that reach out that are a third or half the price of what these guys charge for the exact same quality which would be more fair. If zoom info changes and handles this correctly, I will update the review to be fair with the situation.

Bad business ethics

We canceled subscription as per contract and they keep sending invoices, statements and now collection agencies even if we call them and write to them. No answer, no follow up, very bad business ethics.

We’ve been using ZoomInfo as our go-to platform for B2B data and go-to-market intelligence, and it has been a total game changer. One thing that really surprised us and might surprise others, too is that ZoomInfo’s pricing is actually very reasonable, especially when you factor in the sheer depth and accuracy of the data, the advanced tools, and the time it saves across sales and marketing teams. It’s far from being as expensive as people assume; in fact, it delivers incredible ROI.

Another huge plus for us is the quality of the EU data. We’ve tested other platforms that struggle outside the U.S., but ZoomInfo’s coverage in Europe has been consistently strong, reliable, and fully compliant, which has helped us expand our reach and personalize outreach campaigns across multiple regions.

The platform itself is powerful but easy to use, and the integrations with our CRM and marketing tools work seamlessly. From prospecting to enrichment to intent data, ZoomInfo keeps delivering real business impact, quarter after quarter.

In short: great price, great global data, and an unbeatable set of features. Highly recommended to any team that wants to grow smarter and faster!

Seems I have already requested removal from their services, but being able to spam me is far more important than this.

Unfair and Abusive Behavior from ZoomInfo After Company Closure!
They refuses to cancel our contract even after I submitted legal documents showing our company has been dissolved. I've reached out multiple times with no proper response — I feel they are deliberately stalling and acting in bad faith.
This is abusive and unfair. I am left without support, being forced to pay for a service that no longer makes sense for a closed business.
Also, the platform itself was disappointing, with many outdated or incorrect contacts. I respectfully request immediate contract cancellation with no further charges.

ZoomInfo - Stay AWAY

We thought the information in ZoomInfo was often outdated. We therefore did not use the service. Actually, we forgot about it to be honest. When I got the renewal invoice, I cancelled the service, but apparently, we were five days past the notification date. Do you think they would just let it go? No way.
You know a company has a piss poor product when the only way they can keep you as a customer is to lock you into a contract.

We used ZoomInfo for all of 2024 and paid $2500 per month. $30K total for the year.
We did not book one qualified lead.
Their support team was minimal at best.
Every time we did talk to them, they would look at our campaigns and tell us we were doing everything exactly like we should be. I also asked for some of their clients that have had positive results to visit with, and it took them months to finally give us a reference we could talk to.
I would be cautious moving forward with ZoomInfo based on our experience. Extremely disappointed in our experience, and it was a huge waste of money.
The platform is very confusing to use, the data appears to be old, and customer service is minimal.
They were great during the sales process of them signing us up, but once we signed up and went through their onboarding, we were pretty much on our own. When I did talk to upper management, they were very arrogant and not helpful at all.

Their website lies to you

Their website lies to you. It states to fill out information to get pricing. After filling it out, you have to wait for someone to call you. Then someone calls you and they can’t provide you pricing, but instead you have to setup another meeting with someone to start the sales process and hopefully get a quote at some point.

I was a promoter of ZoomInfo…until the end of our contract

I was a promoter of this product...until the end of the contract term. The contract was signed on Feb 29 2024...and the term was specified as 13 months. I interpreted this as ending on March 31 but they shut down access on March 29. I didn't have time to save my templates or reports. I asked on March 30 for access til March 31 to retrieve our company's work and they said "I have spoken with my leadership and engage support team on this and unfortunately we are not able to reprovision your old platform access, given the contract has expired." I don't agree w/their interpretation' and maybe I'm wrong but is it really worth a one star review to deny a former customer 2 days access to retrieve their data? What a short sighted company

Worst company that I have worked with in more than 40 years in business. The quality of their information is poor at best. i have had to have a staff member go through their data and then verify every piece of information. Worse, once you sign a contract they are unwilling to work with you when there are any seasonal blips.
