Mathematical Audit

How LinkedIn InMail Conversion Metrics Are Calculated

The auditor models a full InMail outreach funnel from sends through responses, meetings, and closed deals to calculate ROI.

Monthly Responses = InMails Sent × Response Rate
Monthly Meetings = Responses × Meeting Conversion Rate
Monthly Deals = Meetings × Deal Close Rate
Monthly Revenue = Deals × Average Deal Value
ROI = ((Revenue - InMail Cost) ÷ InMail Cost) × 100

The average LinkedIn InMail response rate is 18–25%, which is 2.6–5× higher than cold email (1–5%). Personalized InMails generate 3× higher response rates than generic templates. In late 2025, LinkedIn capped Open InMail sends to under 100/month.
