Pros

“I found it to be a powerful tool for lead generation and prospecting, with a large contact database and useful filtering options. While there was a bit of a learning curve at first, the platform offers a lot of value for sales and marketing professionals.”

Lily H.

Business Marketing

“Apollo occasionally struggles with poor data hygiene, and although there are plenty of 3rd party data sources you can incorporate into your Apollo instance to use credits to "waterfall" through these sources to find prospect or company data.”

Nicholas P.

Account Development Manager

“The Chrome extension is especially useful for quickly pulling verified contact data from LinkedIn in real time, which helps streamline daily prospecting workflows.”

Shasta W.

Director of Sales Support

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

“The key and only issue with the platform is that after you clean your leads or check off the option the only show verified emails, your total list reduces by like 20%”

Toni M.

Director of Market Research

“Without Ai chat, optimizing or enriching Works of credits after your credits are gone is brick tool, you can’t use it.”

Zaro D.

Owner

“Some emails can bounce or be missing, and the interface can feel a little busy when I only need quick validation.”

Ellie A.

Co-Founder

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.”
