Newsletter Signal Scanner

Turn your newsletter subscriptions into a structured intelligence feed. Monitors an AgentMail inbox for incoming newsletters, extracts signal-relevant content by keyword campaign, and delivers a weekly digest of what matters — competitor mentions, ICP pain language, market shifts, and emerging topics.

When to Use

• "Monitor industry newsletters for competitor mentions"
• "Alert me when newsletters mention [topic] or [company]"
• "What are newsletters writing about this week in our space?"
• "Set up newsletter monitoring for [client]"

Phase 0: Intake

Newsletters to Monitor

1. Which newsletters should be subscribed to and monitored? (List names or URLs)
   • If unknown, ask: "What 3-5 newsletters does your ICP read?" — then use sponsored-newsletter-finder to discover others.
2. Which AgentMail inbox should receive them? (Or should we create a new one?)

Keyword Campaigns

1. Competitor names to track (e.g., "Clay", "Apollo", "Outreach")
2. ICP pain-language terms to track (e.g., "outbound struggling", "pipeline dried up", "SDR ramp")
3. Market shift terms (e.g., "AI SDR", "agent-led growth", "GTM engineer")
4. Your brand name (to catch mentions)

Output

1. Digest delivery: Slack channel, email, or markdown file? (default: markdown file)
2. Frequency: daily or weekly? (default: weekly)

Save campaign config to the current working directory as newsletter-signals.json (or user-specified path).
