Apollo typically achieves 85-90% accuracy for standard email patterns (firstname@company.com) at US technology companies. Accuracy drops to 60-70% for smaller companies or non-standard email formats. It generally outperforms ZoomInfo for email discovery but lags behind specialized tools like Clearbit for international contacts.
Credits disappear quickly with serious prospecting. A campaign targeting 500 prospects monthly would consume most of the Professional plan's 5,000 email credits. Factor in email verification and follow-up sequences, and you might need the Organization plan ($149/month) or higher for sustainable volume.
Apollo's API is developer-friendly with 100-300 requests/minute on paid plans and comprehensive documentation. Rate limits are generous enough for most custom applications, and webhook support enables real-time integrations. However, some advanced features like intent data may have API limitations not present in the web interface.
