ZoomInfo Reviews 

Contacted by a company that got my personal phone number from Zoom Info. I never consented to them selling my data to customers! If you are considering hiring them, please don't...I am sure there are many people in my position, and they don't want you cold-calling them using these sorts of tactics!

Didn't realize it was a year contract. Tried cancelling immediately and they charged me two more times after first started reaching out (probably reached out 15 or so times after that. No one returned my contacts over a series of months. Finally got someone to respond to an email/pick up a call, and they said they'd cancel the year contract but would not refund charges they made as I was desparately reaching out to them.

They do not respond to requests to remove profiles, which violates data privacy laws. Horrible, unethical company and the info they list is usually wrong too.

I originally had an issue, i was lucky to connect with Jamie who was able to explain things and get my issue resolved. Highly recommend ZoomInfo to any business that can benefit from using their solution. Thank you

Never sign with them! You can never reach anyone for help and they don't let you cancel! Horrible platform and a horrible company. DO NOT WORK WITH THEM!

Zoominfo do not take the most basic step of cross referencing their B2B databases with the Telephone Preference Service (TPS) in the UK.

This is a direct breach of ICO regulations.

We decided to sign up to Zoom info to establish a sales pipeline within our business, we signed a 12 month contract for what they stated on numerous team calls that the information supplied on the portal was up to date and accurate, during the 12 months of the contract over 50% of the information was in accurate, wrong contact information, phone numbers and emails. despite attempts from our strategy department to resolve these issues nothing changed. at the end of the contract we decided not to continue with there services. we signed a contract for 12 months meaning 12 monthly payments, yet they raised 15 and now they are chasing for this payment. they continue to chase using an independent collection agent. this company needs to be audited by the regulating bodies who control this type of organisation, as you can see from there ratings 1.7 this company should be investigated to ensure other companies don't get caught up in paying for something that can not be delivered.

I did not give ZoomInfo (no part of the reputable Zoom that enables web meetings) permission to use my information. So they simply stole it, then sold it to enable others to spam me. ZoomInfo is disreputable and I will trust no company that simply cold contacts me, especially via email. The only positive reviews here come from the second-rate companies that buy stolen data from ZoomInfo.

1) stole my data from no idea where
2)sold it with no consent
3) ignore my multiple request to erase my data

vendors using this service risk to destroy their reputation

Again this company is selling my personal data including my personal mobile - I have complained aslo in the past and nothing is happening

The contacted me out of the blue saying thy were going to process my information. They claimed I would need to go their trust centre or whatnot to stop this blatantly illegal data processing happening. I replied to the E-Mail and believe me unless they react appropriately I will sue this scammy lowlife spam company.

Difficult company to do business with. Cannot reach anyone for support without making an appointment. At present, I can't use my account, which is expensive.

Horrible company. Tried to sign up for a trial, no confirmation code was sent, we tried another of our email addresses, no luck. Suddenly got a call from a guy with a blanket in his mouth (sounded like) and he asked for "some information" about our company. This is not how it works. We cancelled the request.

zoominfo has wrong info about my nonprofit organization -- wikipedia makes it sounds like it's not worth contacting zoominfo to get it fixed.

ZoomInfo completely changed how our sales team works. We used to spend hours searching for contact details but now everything is right there. The buying intent signals help us reach out to the right People at exactly the right time.

Easy to use and powerful tool for improving sales Productivity every day.

My experience with ZoomInfo has been extremely frustrating and disappointing.

From the start, the platform felt overpriced for what it actually delivers. The sales process sets high expectations, but once you’re in, the value just isn’t there. The data quality is inconsistent—many of the contacts are outdated, inaccurate, or simply not useful for real outreach. When you’re relying on a tool like this for business development, bad data quickly becomes a serious problem.

Another major issue is the contract structure. The agreements are large, rigid, and difficult to get out of. It feels less like a partnership and more like you’re locked into something that doesn’t evolve with your needs. There’s very little flexibility, and the cost is hard to justify given the results.

What stood out most to me is the overall approach to customers. Good business, in my view, is about mutual growth—both sides benefiting and building something sustainable. My experience here felt very one-sided, where the focus seemed to be on maximizing revenue rather than delivering real value to customers.

In the end, I wouldn’t recommend it based on my experience. There are other tools and platforms out there that offer better data quality, more transparency, and a more customer-focused approach.

ZoomInfo has been a great product overall. As an actual customer, I find it very easy to use and the data is reliable. The platform also provides strong intent signals which makes it easier to find the right prospects. I especially like how you can identify and contact prospects directly from the portal. Overall, i am very satisfied with the service and have no complaints.

The dashboard is easy to use. They gave us demo sessions and, a 3 day free trial to try the product.
