Apollo.io

Editorial Review

Apollo.io has established itself as one of the best value propositions in the sales intelligence space. Its generous free tier — offering 10,000 email credits per month with real functionality — makes it accessible to solo founders and small teams in a way that competitors like ZoomInfo simply cannot match. The database of 275M+ contacts is competitive with enterprise-grade alternatives at a fraction of the price. The platform's strength lies in combining prospecting data, outreach automation, and analytics into a single tool. Sales teams can go from identifying a target account to launching a multi-step sequence without switching between applications. The Chrome extension for LinkedIn prospecting is well-regarded, and the CRM integrations with Salesforce and HubSpot are solid with bidirectional sync. The main trade-off is data quality. Email bounce rates can run 5-15% depending on the segment, and phone number accuracy is inconsistent. International coverage outside North America is thinner. Teams running high-volume outreach through Apollo's built-in sending should also be careful about domain reputation management. Customer support on lower tiers is primarily self-serve. Despite these caveats, Apollo.io delivers exceptional value for teams that need sales intelligence without enterprise budgets.
