💡 Pro tip: Most tools offer free trials or free tiers. Test 2-3 options side-by-side to see which fits your workflow best.
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.
Compare features, test the interface, and see if it fits your workflow.
