Campaign performance analyzer Claude skill

Use this weekly or at the end of a campaign. It answers three questions: what is working, where does it break, and what do we change next.

Inputs

• Per campaign: contacts, sent, delivered or bounced, replies, positive replies, meetings booked and held, by step, segment, sender and channel.
• Opportunities and pipeline created from those meetings.
• The period.

The play

1. Build the funnel

Contacts → delivered → replied → positive → booked → held → opportunity. Calculate each conversion. Skip open rates as a decision metric; open tracking is unreliable and often turned off for deliverability.

2. Benchmark

Read references/outbound-benchmarks.md for typical ranges by channel and what each gap usually means. Benchmarks are a sanity check, not a target; your own trend matters more.

3. Find the break

The first stage below benchmark is the problem to fix; improving later stages first is wasted effort.

4. Slice it

By step (which email gets the replies), segment (which persona or industry), sender (deliverability or skill), channel. Small slices need samples of 100+ contacts before conclusions.

5. Recommend the next test

One test at a time on the broken stage, with a hypothesis and a success threshold.

Output format

Period: | Campaigns: | Contacts:
Funnel (all): contacts → delivered x% → replied x% → positive x% → booked x% → held x% → opps
Best / worst campaign: <name - why>
The break: <stage - evidence - likely cause>
Slices worth noting: <step, segment, sender findings with sample sizes>
Next test: <hypothesis - change - metric - threshold - sample>
Stop / scale: <campaigns to pause, campaigns to give more volume>

What good looks like

• Diagnosis follows the funnel order.
• Every conclusion states its sample size.
• The report ends in one or two decisions, not twenty observations.
• The common mistake is optimising subject lines when a third of the emails bounce or land in spam.

Rules

• MUST report sample sizes and flag anything under 100 contacts as directional.
• MUST check deliverability by sender before judging copy.
• NEVER call a test winner on fewer than 200 contacts per variant.

Example prompts

• "Here’s last month’s export for 6 campaigns. What’s working and what should we change?"
• "Our reply rate halved this month. Find out why."
• "Build a weekly outbound report template for our SDR team."

Typical ranges for well-run B2B outbound to a targeted list. They vary by market, deal size and offer; use them to spot outliers, then track your own trend.

Meetings to pipeline

By step (cold email)

A healthy 4-step sequence usually gets 40-60% of its replies from step 1, 15-25% from step 2, 10-20% from step 3 and 10-15% from the break-up email. If step 1 gets almost none, the first email or deliverability is broken; if the break-up gets the most, earlier steps are too pitchy.
