Sponsored Newsletter Finder

What it does

This skill finds newsletters relevant to a defined ideal customer profile (ICP), evaluates audience fit across engagement and accessibility metrics, estimates sponsorship cost/CPM, and outputs a ranked shortlist with outreach recommendations. It uses targeted web searches, directory lookups (Substack, Beehiiv, Swapstack, Paved) and simple benchmarks to fill gaps where publishers don't disclose metrics. The goal is to help marketing teams quickly identify cost-effective newsletter sponsorship opportunities for testing or scaling.

When to use it

• You have an ICP and a modest monthly budget ($500–5,000) and want to test newsletter sponsorship.
• You need a prioritized list of candidate newsletters for outreach or media-kit requests.
• You want competitive validation (which competitors are already advertising) before committing budget.

What's included

• Scripts: None bundled, but the skill provides concrete search queries and directories to inspect.
• References: Mentions common sponsorship marketplaces (Paved, Swapstack) and newsletter directories.
• Instructions: Phase-based workflow (intake → discovery → scoring → competitive check → output) with a 5-dimension scoring rubric (audience match, reach, engagement, niche specificity, sponsor accessibility) and output templates for shortlists and outreach messages.
