Dependencies

pip3 install requests

Optional helper script for Substack directory search:

python3 skills/newsletter-sponsorship-finder/scripts/search_newsletters.py --keywords "cloud,AWS,DevOps" --output json

Process

Phase 1: Define Target

Accept from user:

  • Target audience description (e.g., "CTOs and DevOps engineers at startups")
  • Industry keywords (e.g., "cloud, AWS, DevOps, infrastructure, FinOps")
  • Budget range (optional, for filtering)
  • Geographic focus (optional)

Phase 2: Discovery (run searches in parallel)

A) Direct newsletter search (WebSearch)

Run these searches:

  • "[industry] newsletter"
  • "[industry] weekly newsletter developer"
  • "best newsletters for [target audience]"
  • "[industry] newsletter sponsorship"
  • "advertise in [industry] newsletter"

B) Newsletter directory search

Search Swapstack/Paved/SparkLoop for relevant newsletters:

  • "site:swapstack.co [industry]"
  • "site:paved.com [industry]"
  • WebFetch on directory result pages to find listings in the target niche

C) Industry-specific discovery

  • Search for "[industry] blog" and "[industry] content creator" to find people who likely also have newsletters
  • Search for "[industry] newsletter" site:linkedin.com posts
  • Search for Substack newsletters: "site:substack.com [industry keywords]"
  • Optionally run the helper script: python3 skills/newsletter-sponsorship-finder/scripts/search_newsletters.py --keywords "[keywords]" --output json

D) Competitor sponsorship research

  • Search "[competitor name] sponsor newsletter" or "[competitor name] advertise"
  • Check competitor websites for "As seen in" or press pages
  • This reveals which newsletters competitors already sponsor (proven audience match)

Phase 3: Enrich Each Newsletter

For each discovered newsletter, use WebFetch to visit the newsletter page and try to find:

  1. Name — Newsletter name
  2. Author/Organization — Who runs it
  3. URL — Signup page or archive
  4. Estimated audience — subscriber count (often mentioned on sponsorship pages or About pages)
  5. Topic focus — What it covers
  6. Frequency — Daily, weekly, monthly
  7. Sponsorship info — Rates, format (dedicated send, banner, classified), contact
  8. Audience quality — Is the audience primarily decision-makers or junior folks?
  9. Social proof — Notable sponsors, testimonials

Phase 4: Score & Rank

Score each newsletter (0-10):

  • Audience overlap with target ICP (+3 max)
  • Audience size (+2 for 10K+, +1 for 5K+)
  • Sponsorship availability confirmed (+2)
  • Reasonable pricing for budget (+1)
  • High engagement signals — open rates mentioned, active community (+1)
  • Competitors sponsor it — proven audience match (+1)

Phase 5: Output

Save results to the specified output path as markdown:

## Next Steps
1. Reach out to Tier 1 newsletters for rate cards
2. Request media kits from Tier 2 newsletters
3. Set calendar reminder to refresh this list quarterly
4. Monitor competitor sponsorships monthly

Tips

  • Run once per client to establish a sponsorship pipeline
  • Refresh quarterly as new newsletters launch frequently
  • Check competitor sponsorships monthly — if a competitor starts sponsoring a newsletter, it validates the audience
  • Combine with agentmail to automate initial outreach to newsletter operators
  • Use company-contact-finder when a newsletter's sponsorship contact is not publicly listed
  • Newsletters with 5K-50K subscribers often offer the best ROI for B2B sponsorships — large enough audience, small enough for personal touch

概要と使いどころ

Research supported advertising promises from a specific buyer's context, current product facts, customer language and observed ads. Turn them into static, video or copy ideas; match video ideas to actual recipes and save a product-scoped angle bank for write-video-ad-script. Product-led discovery can use verified facts without reviews. Reference persistence and reach are observations, not proof of performance.

The intake stage of a Meta ad harness. Researches the brand first, states what it assumes, and asks only what it cannot infer and what would change money, claims or legal exposure if guessed wrong — at most four questions a turn, in plain business language. Writes the brand's stable facts (ads/brand.md), the campaign brief, and a log of what was asked vs assumed. Use it when someone wants to run Meta ads and the brand's ad facts are not yet recorded.

Analyze the message match between your ads and landing pages. Checks if the promise in the ad copy carries through to the landing page headline, body, and CTA. Flags disconnects that kill conversion rates. Works with Google, Meta, and LinkedIn ads.

Turn a brand's facts, a campaign brief and the product into a one-minute Meta ad strategy with its reasoning — goal, audience, objective and placements, budget split, how many ads and how different they must be (generate 3x so the user can choose), the test frame, the success metric, and safety rules for the user to accept. Decides what launch-meta-ad-campaign then executes, and re-reads the strategy after a deep check to show which assumption changed. Use it after intake and before any creative is generated or any campaign is built.
