Pros

“The contact database is extensive, and the filters helped us build targeted lead lists quickly, saving time compared to researching companies manually.”

Bill L.

Vice President of Sales and Operations

“ZoomInfo makes it super simple for us to enrich our CRM account and contact data, and helps us prioritize our accounts based on key information”

Matt K.

RevOps Manager

“As with other similar services one challenge is accurate data on private companies and stale data, especially from smaller orgs.”

Eric L.

Sr. Solutions Engineer

Pros

“I work across consulting and B2B media, so I'm constantly building targeted contact lists, and being able to pull verified emails and direct dials right from a prospect's profile, without bouncing between tabs, has genuinely changed how fast I can put a campaign together.”

Ravi, R.

Engineer,

“Its core strength lies in its real-time data search capability, which allows users to access updated contact information instead of relying only on static databases.”

Alizaheer V.

key associate manager

“AI is its real-time search engine, which completely changes how I prospect because it researches contact information across the web the exact moment I request it, rather than pulling from a stale, pre-downloaded database.”

Jan S.

Owner, Chief Researcher

Cons

“ZoomInfo is a mediocre prospecting tool that has built a set of tools around the core need of having relevant, accurate contact data. And in those tools are hits and misses of all sorts. ”

Shawn S.

Business Relations

“I find mobile numbers can be incorrect, and there are a lot of privacy concerns from individuals when I reach out using the information ZoomInfo has collected.”

Marissa W.

Senior Account Executive

“Their entire operation appears structured to extract maximum revenue with minimal accountability, and to lock businesses into unfavourable terms with no regard for the actual experience or outcome.”

george s.

Director

Cons

“AI is its inconsistent data accuracy, which frequently results in frustrating 20% to 30% email bounce rates because its real-time engine lacks a strict multi-source "waterfall" verification process to catch outdated records.”

Jan S.

Owner, Chief Researcher

“Worst of all, their billing and cancellation practices are a total nightmare; they strictly enforce hidden 60-day auto-renewal notice policies that lock you into unexpected, non-refundable 12-month contract extensions that customer support refuses to waive.”

Jan S.

Owner, Chief Researcher

“I find that completely unacceptable. If your cancellation procedure requires the customer to submit a request and then wait for YOUR billing department to contact them, your company should not benefit when your billing department fails to make that contact.”
