Contract Lock-In, Add-On Fees & API Rate Gotchas
Buyers often overlook that Apollo.io's 'Unlimited' email features are subject to strict Fair Use Policies that can throttle high-volume automated outreach. Conversely, ZoomInfo's pricing is highly modular; the base license often excludes critical features like Streaming Intent or advanced CRM workflows, leading to significant cost creep once the platform is fully integrated into an enterprise stack. Both vendors enforce strict non-rollover policies on credits, meaning unused capacity at the end of a billing cycle is lost, effectively penalizing teams that fail to optimize their consumption patterns.
