Apollo vs. ZoomInfo for the Outbound-First Sales Team
ZoomInfo's pricing is now a category-defining problem. Apollo's data quality is not what the marketing implies. We tested both at three outbound-first sales teams. The right answer depends almost entirely on whether your buying committee includes finance.

↑ What works
- +Apollo's all-in-one offering is genuinely the right shape for the modern outbound team
- +ZoomInfo's data depth on enterprise contacts remains category-leading in the segments it covers
- +Both vendors have closed the worst of their data hygiene gaps from 2022
↓ Where it disappoints
- −ZoomInfo's per-seat pricing has crossed into territory only Salesforce-grade procurement can love
- −Apollo's mobile data and senior-leadership email coverage are weaker than the dashboard suggests
- −Both vendors have meaningful annual price escalators that should be negotiated before signature
The sales-tech buyer's question is not "which data vendor has the best data." It is "which combination of data, workflow, and pricing produces enough qualified meetings to feed the pipe at a cost the CFO will sign for." Apollo and ZoomInfo are the two structurally serious answers in 2025. They have moved in opposite directions on price and similar directions on product, and that produces a decision more nuanced than the trade press treats it.
We tested both at three outbound-first teams during Q1 2025: a 12-rep B2B SaaS team, a 28-rep professional services firm, and a 7-rep startup running aggressive outbound to enterprise prospects. We measured data accuracy on randomized samples, coverage in specific segments each team cared about, mobile and email deliverability, workflow integration, and total cost over a normalized usage scenario.
Where Apollo wins
Workflow integration. Apollo is the only major data vendor that has built — at this point in the company's evolution — a coherent all-in-one motion for the outbound team. Sequences, dialer, calendar booking, and the data layer are integrated cleanly. The result is a single tool a rep can live in for the full day and a meaningfully shorter onboarding for new hires. ZoomInfo's equivalent (Engage) has improved but feels like an acquisition still being integrated.
Pricing is the second Apollo win. The per-seat cost — currently $99 for the Pro tier we tested — is a fraction of ZoomInfo's enterprise pricing. The credit allotment is generous enough that a disciplined team will not run out at this tier. Annual escalators are present but modest by category standards.
ZoomInfo's pricing has crossed into territory only Salesforce-grade procurement can love. That is a category-defining problem.
Where ZoomInfo still wins
Data depth in specific industry segments. ZoomInfo's coverage of large-enterprise contacts in financial services, healthcare, and manufacturing remains the deepest in the category. We were not able to find a segment where Apollo's coverage was meaningfully better; we found several where ZoomInfo's was meaningfully better. For the team selling into 5,000+-employee enterprises in regulated industries, ZoomInfo is still the right answer.
Intent and signal data is the second ZoomInfo win. The signals — buying intent, technographic data, hiring trends — are richer and more reliable in the segments ZoomInfo prioritizes. Apollo's equivalent has improved markedly but is a step behind.
Where both fall down
Senior-leadership email coverage is weaker at both vendors than the marketing claims. We tested deliverability against verified C-suite contacts at randomized samples of 50 enterprise companies. Apollo's deliverability rate was 58%. ZoomInfo's was 66%. Both are usable; neither is the 90%+ figures that show up in vendor marketing.
Mobile phone coverage is the second shared gap. Apollo's mobile coverage is in the 35–45% range for enterprise contacts in our test. ZoomInfo's is 50–60%. Both are usable for outbound dialer work but require expectation-setting with a sales team that has been told the data is comprehensive.
On pricing
ZoomInfo's enterprise pricing has crossed a meaningful threshold in the last 18 months. The per-seat cost for a real enterprise SKU is now in the $1,500–$2,500 per user per month range when bundled with intent data and engagement. The annual contract for a 30-rep team can run $400K–$700K. That is a different category of vendor relationship from Apollo's $99-per-seat motion and produces a fundamentally different procurement conversation.
Apollo's pricing has crept upward but remains an order of magnitude below ZoomInfo at the enterprise tier. The gap is large enough that finance teams have begun, in our experience, to push back on ZoomInfo renewals at the next contract cycle.
The verdict
Apollo is the right answer for the outbound-first team that values workflow integration, has reasonable data needs, and lives within finance-friendly per-seat costs. ZoomInfo is the right answer for the team selling into specific enterprise segments where data depth is the bottleneck and where the budget exists to pay for the depth. Both at once is a real pattern at growth-stage organizations and increasingly the only honest answer for the team that needs both ends of the market.
- Carrie M.
Run both. Apollo for the day-to-day workflow, ZoomInfo for the targeted enterprise pursuits. Each does its job.
- Vincent O.
ZoomInfo's pricing is genuinely insane. Our renewal came in 47% higher than the prior year for the same SKU. We migrated to Apollo in 90 days.
- S. Patel
Apollo's senior-leadership email coverage is the part nobody warns you about. The C-suite contacts are about 60% deliverable in our experience.
- James C-P (author)
@S. Patel — yes, that gap is real. The mid-market and director-tier coverage is materially better than the C-suite coverage at Apollo.
- Mariko T.
We use Clay on top of Apollo for the data orchestration layer and that combo has been the right answer. Worth a separate review.
