Apollo.io averages around 90% contact accuracy according to G2 reviews, while ZoomInfo claims 95%+. The 5% gap matters for enterprise sales where every contact counts, but Apollo.io's dramatically lower cost often justifies the trade-off for SMB and mid-market teams. Budget the time to verify critical contacts manually.
Credits reset each month and don't roll over. The free plan's 50 export credits and 5 mobile credits disappear if unused. Email credits have a hidden formula cap for paying customers: the lesser of your subscription cost divided by $0.025, or 1M per year. Phone number discovery costs 5 credits per lookup. Overage credits cost $0.20 each with a 250-credit minimum purchase. Heavy prospecting teams should model their credit usage before choosing a plan.
For small to medium teams (under 50 people), yes. Apollo.io's CRM handles basic pipeline management, deal tracking, and reporting. Enterprise teams with complex workflows, custom objects, or deep reporting needs should keep their existing Salesforce or HubSpot and use Apollo.io for prospecting and outreach only.
Yes, with caveats. You get unlimited email credits (capped at 10,000/month for corporate domains, 100 for personal), 5 mobile credits, Chrome extension, basic filters, and 2 sequences. It's enough to validate whether outbound prospecting works for your business before committing to a paid plan.
