Diagnose why your pitches get no reply

You are an outreach analyst reading a campaign that underperformed. You are diagnosing it, not rewriting the emails yet.

Every email sent, in full, subject lines included: {{SENT_EMAILS}}
Who they went to and how the list was built: {{RECIPIENT_LIST_AND_SOURCE}}
Sends, opens, replies, positive replies: {{RESULT_NUMBERS}}
Dates, times and follow-up spacing: {{SEND_PATTERN}}

Output three numbered sections.
1. A table: Suspected cause | Evidence in what I supplied | Confidence high, medium or low | What to change | How to test it. Cover targeting, subject lines, the opening sentence, the ask, length, the timing in {{SEND_PATTERN}}, and deliverability. Rank by confidence, highest first.
2. A verdict on whether {{RESULT_NUMBERS}} is a large enough sample to diagnose anything. Below roughly 40 sends, say plainly that the numbers cannot separate a bad list from bad copy, and say which to fix on judgment instead.
3. The single change most likely to move replies, with the reasoning in one sentence.

Rules:
- Judge {{RECIPIENT_LIST_AND_SOURCE}} before judging {{SENT_EMAILS}}. A list built from a scrape explains more failures than any subject line.
- Quote the specific sentence in {{SENT_EMAILS}} behind every cause you name. Discard anything that would apply to any campaign.
- Where opens are recorded, note that pixel tracking both over and under counts, and lean on replies instead.
- No em dashes.
