Four ratings that do not agree: 4.5, 4.1, 1.8 and 1.6
Scores read in October 2026 (G2: a search-results snapshot from September 2026). G2 and Capterra block automated access, so their figures come from search results; G2 now lists ZoomInfo’s sales product as “GTM Workspace - Powered by ZoomInfo”. ZoomInfo’s own pages show the same 4.5 with 8,721 to 12,960 reviews, depending on the page.
What satisfied users rate
- Ease of use (4.3 on Capterra)

Renewals, contracts and support: the most common complaint
On Trustpilot, 65% of the 343 reviews give one star and 31% give four or five; ZoomInfo has claimed its profile, and Trustpilot notes that it has not replied to negative reviews. The recent one-star reviews describe no onboarding and no human support, and one calls the service a scam.
The contract is behind many of these complaints. ZoomInfo’s licence terms say the agreement is not cancellable for its term, usually 1 to 3 years, billed in advance; if ZoomInfo ends it for a customer’s breach, the rest of the term becomes due. Until the version of March 6, 2024, the terms also renewed the contract automatically unless notice was given 60 days before the end, at 10% above the previous price; contracts signed then may still carry that clause.
On Capterra, value for money is ZoomInfo’s lowest sub-score (3.5 out of 5, over 242 reviews) and customer service the next lowest (3.8). Support works 5:00 to 17:00 Pacific time, Monday to Friday, according to the terms. Before signing, ask for the term, the renewal clause and the notice period in writing.
Reviews from people who found themselves in the database
A share of the Trustpilot reviews do not come from customers at all. Their authors found their own details in ZoomInfo: a personal mobile number listed as a business line, data they say was resold, deletion requests that went unanswered.
ZoomInfo handles removals through its Privacy Center, and its customers must apply its suppression list at least once a month. One of its sources is its own free tier, whose users can share the contacts of the mailbox they connect (a condition of access in its terms, optional according to its FAQ). How to ask for removal is on our ZoomInfo page.
The ZoomInfo extension after the July 2026 redesign
The extension counts 300,000 users on the Chrome Web Store. Its rating has collapsed in a few weeks, from 3.49 on 302 ratings on September 11, 2026 to 1.64 on 295 on October 16, 2026.
The reviews since July 2026 point to the redesign as a side panel (version 12.9.3): reviewers report that most of the features they used are gone, that they cannot sign in, and that the panel closes their other side panels. ZoomInfo keeps shipping updates (version 12.22.1 on October 13, 2026); whether they win the ratings back is something to check on the store before relying on it.
What satisfied users rate highly
The users who keep ZoomInfo rate it well: 4.5 on G2 over about 9,000 reviews, and on Capterra 4.3 for ease of use and 4.2 for features, with 78% of reviews positive, 13% neutral and 10% negative. On Trustpilot, 27% of reviews give five stars, and recent ones praise the onboarding and the product itself.
ZoomInfo also cites a 4.7 on Gartner Peer Insights for its ABM product and its position as a Leader in Gartner’s Magic Quadrant for ABM platforms in 2026; we only found those on ZoomInfo’s own pages.
The customers ZoomInfo targets, by its own description
ZoomInfo is unusually frank about its fit. It aims at sales, marketing and RevOps teams in companies of 100 employees and up, and names its weaker fits: B2C businesses, individual users who only need a few contacts a month (for whom it says ZoomInfo Lite may be enough), and “teams that sell only into a single non-North-American market and should test regional coverage first”.
That last point matters outside the United States: ZoomInfo lists 137.9 million contacts in the US, against 15.5 million in the UK and 7.7 million in France. For a team that prospects mostly in Europe, the price of the emails it actually needs is the other measure: Emelia charges 1 credit per email found, only when one is found, and finds phone numbers through a waterfall across several providers.
ZoomInfo reviews: questions people ask
ZoomInfo is a legitimate company: ZoomInfo Technologies Inc., listed on the Nasdaq since June 4, 2020, with 35,000+ paying customers. The harshest Trustpilot reviews, one of which calls the service a scam, describe contracts that cannot be cancelled, missing support and personal numbers listed in the database; read the contract terms before signing, and use the Privacy Center if your own details are listed.
Different people write them. G2 and Capterra collect reviews from users of the product, who mostly like the data and the tool. Trustpilot is open to anyone, including former customers in a dispute and people who found themselves in the database: 68% of its reviews give one or two stars.
Not on Trustpilot: its profile, claimed since September 2020, is marked as not replying to negative reviews. Questions about your own data go to ZoomInfo’s Privacy Center, at privacy.zoominfo.com.
