Independent users mostly rank ZoomInfo as the most complete contact database, especially for US and enterprise prospecting and mobile numbers, and teams that moved over from cheaper tools such as Seamless report a clear difference. The trade-off is price, contract and cancellation terms that users find aggressive, and data that is still often wrong; several reps say emails, numbers and org charts miss badly and that its intent features rarely produce pipeline. Discussion is broad, with about 40 independent opinions; about a fifth of mentions were set aside as promotional, including comments from ZoomInfo staff, a Prospeo seeding cluster and an identical Cognism pitch posted by two accounts.
Users like
- Teams that moved from Seamless, Slintel or Apollo report noticeably more accurate and thorough data, and one team returned to ZoomInfo after trialing Seamless[1][2][3][4][5][6][7]
- Strongest for US and enterprise accounts: users call it the best fit for Fortune 500 prospecting and say calling enterprises without it leaves you stuck[1][2][3]
- Mobile numbers are the main draw for callers; one rep gets a mobile about 75% of the time, while noting it is far from perfect[1][2][3][4]
- Integrations add value: CRM and call-recording tie-ins surface decision makers before calls, and reps connect it to Salesforce and AI assistants for account research[1][2]
Users complain about
- Expensive: users call it ridiculously or prohibitively priced, question the premium given its errors, advise negotiating hard, and say reps at some companies buy other tools because it is so enterprise-focused[1][2][3][4][5]
- Data is still often wrong: reps report bad emails, wrong phone numbers, off-base org charts, catch-all addresses and connect rates under 1% for one team[1][2][3][4][5][6]
- Intent and pickup-likelihood signals are seen as unreliable: users call intent smoke and mirrors and say a 'more likely to pick up' list was still mostly cold[1][2][3]
- Contract and sales practices draw complaints: sketchy legal language and a trigger-happy legal team at cancellation, plus persistent sales calls after prospects say no[1][2][3][4]
Independent users largely agree Clay is the most flexible way to run waterfall enrichment and custom research workflows, because it can query many providers and route the results into a CRM. The trade-off is cost and effort: credits burn quickly, the 2026 move to billing every workflow action makes bills hard to predict, and teams say it takes a skilled builder or a dedicated person to get value from it. More than half of the Reddit mentions are promotional, including a cluster of about a dozen r/coldemail comments from May and June 2026 that all pair Prospeo with Clay in the same talking points, plus many replies plugging Clay alternatives such as Bitscale, Floqer, Airscale and pipe0; this review rests on about 20 independent opinions.
Users like
- Waterfall enrichment across many providers: users say it pulls from more sources than single databases like Apollo and fills gaps they would otherwise miss[1][2][3][4][5]
- Flexible enough for custom work once someone learns it: AI account research, hiring signals, CRM imports and middleware between other tools[1][2][3][4][5]
- Costs become manageable for teams that filter lists with cheap signals before enriching, or bring their own provider API keys instead of paying Clay's data markup[1][2][3]
Users complain about
- Expensive: credits burn quickly because it can do so much, and one team cites a $26k quote for what it considered entry-level work[1][2][3][4][5]
- The 2026 pricing change bills every workflow step, HTTP call and CRM push as an action, which users say makes costs hard to predict at agency scale[1][2]
- Steep learning curve: every use case has to be built by hand, and some teams say they would need to hire someone just to run it[1][2][3][4]
- Economics weaken at high volume: users who run it as a bulk data provider find it expensive and suggest reserving it for a filtered or top-priority slice of the list[1][2]
