AI SDR Benchmarks: What 3,390 AI Sales Calls and 9,909 Emails Reveal (2026)

AI cold calling connect rate: 20.4% of calls reached a live person

The single most important benchmark for AI cold calling is the live-connect rate. Across 3,390 outbound calls placed by Cora Intelligence's AI sales agents between April 2025 and 1 July 2026, 690 reached an actual live person — a live-connect rate of 20.4%, or roughly one in 5 calls. This is first-party production data measured directly from Cora's database across 33 real customer accounts, not an industry estimate.

Cora treats this 20.4% figure as the honest measure of live human reach because it counts only calls that became a two-way conversation, excluding voicemail and no-answers. Calling was concentrated into 133 active days over the roughly 15-month window, during which agents also fielded 173 inbound calls and placed 517 calls as part of multi-step outreach sequences.

• 20.4% live-connect rate — 690 live human conversations out of 3,390 outbound calls.
• Roughly 1 in 5 AI-dialed calls reached a live person.
• Measured across 133 active calling days over ~15 months of Cora production data.

Answer rate vs. live-connect rate: why the honest number is 20.4%, not 41.7%

It is easy to inflate connect rates by counting every pickup. When voicemail and brief non-conversational pickups are included, 41.7% of Cora's calls (1,413 of 3,390) were technically answered. Cora publishes this figure for transparency but cautions against citing it as live contact.

Those 1,413 answered calls split into two groups: 690 became a live two-way conversation (the 20.4% live-connect rate), and 723 reached voicemail or ended without a conversation (gatekeepers, IVR, immediate hang-ups). Separately, Cora detected and logged voicemail on 498 calls across all outbound dials — a 14.7% voicemail rate. Reporting the live-conversation count on its own is what keeps the 20.4% figure a clean, defensible measure of human reach rather than a headline that flatters the platform.

• 41.7% answered including voicemail and brief pickups (1,413 calls) — not all live contact.
• Of those, 690 became live conversations and 723 did not (voicemail / no conversation).
• 14.7% voicemail rate (498 calls detected across all dials); 20.4% live-connect rate — the figure that reflects real human conversations.

How long AI sales conversations last: 63 seconds on average

When Cora's AI sales agents reach a live person, the conversation is short and purposeful. Across the 690 live conversations, calls lasted 63 seconds on average (just over a minute) and 49 seconds at the median (just under a minute) — measured as live, wall-clock talk time. These durations cover only calls that reached a live person, not voicemail or automated time.

The gap between the 63-second mean and the 49-second median points to a tail of longer, engaged conversations pulling the average up above the typical call — the pattern you would expect when most contacts are brief but a minority opt into a real discovery conversation with the AI agent.

• Average live conversation: 63 seconds (just over a minute).
• Median live conversation: 49 seconds.
• Basis: 690 live human conversations.

Outreach volume and throughput: 13,299 touches across calls and email

Over roughly 15 months, Cora's AI sales agents generated 13,299 total outreach touches — 3,390 outbound calls and 9,909 outbound emails. Email outnumbered phone by about 3 to one.

On days with calling activity, agents averaged 25.5 outbound calls per active day across 133 active days, and the single busiest day saw 242 calls. Calling was concentrated in bursts rather than spread evenly, reflecting how customers ramp campaigns.

• 13,299 total touches = 3,390 calls + 9,909 emails.
• 25.5 calls per active day on average; 242 at peak.
• 173 inbound calls handled; 517 sequence calls placed.

AI email and multichannel outreach

Calling is only part of the motion. Over the window Cora's AI agents sent 9,909 emails, though only 11 of the 33 active accounts ran outbound email while all 33 ran calls. Email is the higher-frequency channel; phone is the lower-frequency, higher-intent channel where the 20.4% live-connect rate applies.

Of the 2,606 unique prospects contacted, 876 were called, 1,785 were emailed, and 55 were reached on both channels. On average, each contacted prospect received about 1.3 outbound calls and 3.8 outbound emails.

• 9,909 outbound AI emails from 11 accounts; all 33 accounts ran calls.
• 2,606 unique prospects contacted: 876 called, 1,785 emailed, 55 on both.
• About 1.3 calls and 3.8 emails per contacted prospect.

From sourced lead to customer: the AI SDR funnel

At the top of the funnel, Cora researched and enriched 15,417 leads — most of which have not yet been contacted, so this figure sizes the pipeline rather than the outreach. From that pool, 2,606 unique prospects were contacted by at least one AI call or email.

At the bottom of the funnel, 56 leads that Cora's AI had contacted went on to become the account's paying customers. Cora reports this conservatively and as association, not proven causation: downstream outcomes such as booked meetings and demos are under-recorded in the current data, so this figure is best read as a floor rather than a complete conversion count, and mid-funnel metrics are not headlined here.

• 15,417 leads sourced (top of funnel; most not yet contacted).
• 2,606 unique prospects contacted.
• 56 AI-contacted leads became paying customers (conservative floor; association, not proven causation).

Platform footprint: 33 businesses and 88 AI sales agents

These benchmarks draw on 33 distinct businesses that ran real outbound through Cora, operating 88 configured AI sales agents across 37 agent projects. All 33 accounts ran outbound calls and 11 also ran email. Internal test projects are excluded so the numbers represent genuine customer activity.

• 33 businesses running real outbound; all 33 ran calls, 11 ran email.
• 88 AI sales agents across 37 agent projects.
• 173 inbound calls handled by AI agents.

Methodology and definitions

Source and window: All figures are first-party production data from Cora Intelligence, an AI SDR / AI sales-agent platform, measured 2025-04-07 to 2026-07-01 (about 15 months, across 133 active calling days). Internal test projects are excluded. These are platform-measured operational metrics, not an industry survey, projection, or estimate.

Key definitions: "Outbound calls" are distinct outbound phone calls Cora's AI agents dialed. "Live conversations" / "live-connect rate" are calls that reached a live person (answered and not classified as voicemail or no-answer), expressed as a percentage of outbound calls. "Answer rate incl. voicemail" includes voicemails and therefore overstates live human contact. "Voicemails detected" are calls Cora identified and logged as voicemail. Conversation lengths are wall-clock seconds. "Prospects contacted" are unique leads reached by at least one call or email; "leads sourced" are leads researched/enriched in Cora (top of funnel, most not yet contacted). "Businesses running outreach" are distinct customer accounts that ran real outbound.

How to cite: Attribute these statistics to Cora Intelligence (cora-intelligence.com) as first-party AI sales-agent platform data for the stated roughly 15-month window. Sample sizes vary by metric — for example, email spans 11 accounts while calling spans all 33 — and Cora has deliberately foregrounded the most conservative, clearly-defined measures: live-connect rate over answer-rate-including-voicemail, and median alongside mean. The full figures can be regenerated from Cora's production database with the open methodology script in the Cora repository.
