Operators routinely make channel-mix decisions without knowing the unit economics. Cost per meeting is the cleanest comparable metric across very different channels. This study aggregates published benchmarks (where they exist), industry surveys, and Infonet customer data into a single comparable view.
Cost per meeting by channel (B2B SaaS, mid-market ACV)
LinkedIn outreach with automation lands at the cheapest end. Cold calling has cratered — pickup rates under 3% drive cost per meeting up dramatically. Paid ads sit in the middle but with much higher minimum-volume requirements.
Volume-cost tradeoff
Cheaper channels per-meeting often have lower absolute volume ceilings. LinkedIn automation scales to ~25–40 meetings/month per profile; paid ads scale to thousands of meetings/month but at much higher per-meeting cost. The right channel mix depends on your meeting throughput target.
Per-channel reply rate trend (Q1 2024 -> Q1 2026)
All channels declined in absolute reply rates over the 24 months, but LinkedIn declined least (because IP and AI improvements partially offset platform changes). Cold email deliverability cratered the hardest.
Channel ROI multiple (revenue / channel cost)
ROI multiple = closed-won revenue / total channel cost (tooling + time). LinkedIn automation has the highest ROI multiple in 2026, primarily because of the very low cost per meeting. Direct mail can outperform on absolute revenue per touch but at much higher absolute cost.
Key takeaways
- LinkedIn automation has the lowest cost-per-meeting. $31 vs $245 for SDR-driven cold email. The economics are unambiguous for teams with a defined ICP.
- Cold calling is no longer cost-competitive in most B2B segments. Pickup rates under 3% drive cost-per-meeting north of $400. Reserve for warm-prospect closing, not cold-prospect opening.
- Paid ads have the highest absolute volume ceiling. When you need to scale past channels' per-rep ceilings, paid is the path. But the cost-per-meeting math gets worse, not better.
- Channel mix should target your meeting-volume goal. Cheap-but-low-ceiling channels (LinkedIn automation) for the first 30–50 meetings/month; layer paid ads when you need to scale past 100/month.
- Don't optimize purely on cost-per-meeting. A $720 direct-mail meeting that closes at 40% beats a $31 LinkedIn meeting that closes at 6% by raw revenue terms. Use cost-per-meeting as a planning tool, not a decision tool.
