1. Executive Summary

Cold calling remains one of the most effective prospecting methods in B2B and high-ticket B2C sales, yet traditional approaches are suffering from historically low answer rates. This comprehensive research report analyzes 850,000+ outbound calls processed through Rizzly's AI voice agent platform to uncover actionable insights about answer rates, optimal calling times, and cost efficiency.

The findings are transformative: AI-powered cold calling dramatically outperforms human-only approaches across every meaningful metric. With proper implementation, sales teams can expect to increase answer rates by 1,075%, reduce cost per appointment by 73%, and generate 4-6x more qualified opportunities from the same lead volume.

Key Research Findings:

• 100% answer rate with AI voice agents vs 8% human baseline

• 10:00am-11:30am is the optimal cold calling window (32% higher connect rates)

• Wednesday and Thursday outperform other days by 23%

• $4.23 average cost per appointment with AI vs $15.67 human-only

• 6 call attempts is the optimal follow-up sequence for maximum conversion

2. Human vs AI Cold Calling: The Data

The most striking finding from our research is the dramatic difference in answer rates between human cold callers and AI voice agents. This isn't a marginal improvement—it's a fundamental shift in what's possible with outbound prospecting.

2.1 Why Prospects Answer AI Calls

Several factors contribute to the massive answer rate disparity:

Local Presence Dialing
AI systems use verified local numbers that match the prospect's area code, increasing trust and answer likelihood by 340%.

Optimal Timing
AI automatically schedules calls during statistically proven windows when prospects are most likely to answer.

Persistent Follow-Up
AI never forgets to follow up, executing 6-touch sequences consistently—something human reps accomplish only 20% of the time.

Spam Score Management
AI platforms actively manage caller ID reputation, rotating numbers to maintain clean spam scores across carriers.

Answer Rate Comparison

AI Voice Agent (Rizzly) – 100% answer rate
Power Dialer (Human) – 12% answer rate
Manual Dialing (Human) – 8% answer rate

2.2 The Conversation Quality Factor

Answer rate alone doesn't tell the full story. AI voice agents also demonstrate superior conversation-to-appointment conversion rates because they:

• Deliver pitch-perfect messaging every time, eliminating human error and inconsistency

• Never experience fatigue, rejection sensitivity, or motivation dips

• Handle objections with pre-trained, optimized responses

• Seamlessly transfer qualified prospects to live reps at the perfect moment

• Capture detailed conversation notes and lead intelligence automatically
