Apollo.io and ZoomInfo are two of the most recognized names in B2B sales intelligence, but they occupy very different positions in the market. Apollo has disrupted the space by offering a surprisingly capable all-in-one platform — CRM, email sequencing, dialer, and a 275M+ contact database — starting at just $49/user/month with a free tier that gives you 10,000 credits monthly. It's the platform that democratized access to sales intelligence for startups and SMBs who previously couldn't afford tools in this category.
ZoomInfo, on the other hand, is the enterprise incumbent. With 300M+ contacts, advanced Bombora-powered intent data, org charts, and sophisticated firmographic intelligence, it's built for large sales organizations with the budget to match — plans start around $14,995/year and enterprise packages regularly exceed $40,000-$100,000. There's no free tier, no public pricing, and no way to get started without a sales call.
The choice between them often comes down to budget and scale. But there's a critical dimension both platforms underperform on: email accuracy. When your outreach depends on emails actually reaching inboxes, neither Apollo's ~84% nor ZoomInfo's user-reported accuracy (often well below the claimed 95%) delivers the reliability modern outbound teams need.
Feature Comparison
Apollo's greatest strength is consolidation. A single subscription gives you prospecting, enrichment, email sequences, a built-in CRM, a dialer, and basic intent signals. For early-stage companies trying to minimize their tech stack, this all-in-one approach is genuinely compelling. The free tier — 10,000 credits/month with basic sequencing — lets solo founders start prospecting without any spend at all.
ZoomInfo's advantage is depth. Its intent data (powered by Bombora), organizational charts, website visitor identification, and technographic data give enterprise sales teams intelligence that Apollo's platform simply doesn't match. If you need to know which companies are actively researching your solution category, or you need to map an entire buying committee's reporting structure, ZoomInfo has capabilities Apollo can't replicate.
Where both fall short is data quality at the point of contact. Apollo's database is large but emails are not verified in real-time — you're relying on data that may have been accurate when it was last crawled, not when you hit send. ZoomInfo suffers the same problem at a much higher price point, with G2 reviewers consistently reporting email bounce rates that exceed the platform's accuracy claims.
Pricing
The pricing gap between Apollo and ZoomInfo is massive. Apollo's free tier includes 10,000 export credits per month, basic sequences, and CRM access. The Basic plan ($49/user/month) adds unlimited sequences, A/B testing, and more credits. Professional ($79/user/month) unlocks advanced reports, dialer, and intent filters. Organization ($119/user/month) adds AI-assisted workflows and custom reporting.
ZoomInfo doesn't publish pricing and requires every prospect to go through a sales process. Based on G2 reviews and user reports, the Professional plan starts around $14,995/year for 5,000 credits and 3 seats. Advanced plans range from $25,000 to $30,000/year, and Elite packages for larger organizations can exceed $40,000 to over $100,000/year. All plans require annual contracts with auto-renewal — miss the 60-day written cancellation window and you're locked in for another year.
For a 5-person team doing 10,000 lookups per month, Apollo costs roughly $3,000-7,000/year. The same team on ZoomInfo would spend $15,000-$30,000+, with significant hidden costs for credit overages, additional seats, and premium modules. Apollo is the clear winner on value for teams under 50 people.
