Newsletter Sponsor Research

This drill identifies newsletters available for paid sponsorship, evaluates their audience quality and pricing, and produces a ranked shortlist ready for booking. Unlike partner research for free co-marketing, this drill focuses on paid placements and factors in cost-efficiency.

Input

• Your ICP definition (firmographics, buyer persona, pain points)
• Budget range per placement (e.g., $100-500 for smoke test, $500-2,000 for baseline)
• Target number of evaluated newsletters (default: 30 candidates, top 10 shortlisted)
• Preferred newsletter frequency (weekly preferred for testing velocity)

Steps

1. Search newsletter advertising marketplaces

Use the newsletter-marketplace-search fundamental to query Paved, Swapstack, Sparkloop, and Letterhead. Search for newsletters in your ICP's industry vertical. Also run a web search for "{your_industry}" newsletter sponsorship and "{your_industry}" newsletter advertise to find newsletters selling sponsorships directly.

Pull 30-50 candidate newsletters. For each, capture: name, publisher, subscribers, open rate, price, format, and source.

2. Research newsletter publishers via Clay

Use clay-company-search to find the companies behind each newsletter. Use clay-enrichment-waterfall to enrich with: company size, funding stage, industry, and the contact info for the person who manages ad sales or partnerships. This identifies who to negotiate with and verifies the publisher is a real, operating company.

3. Audit each newsletter for quality and fit

For the top 20 candidates (sorted by effective CPM), run the partner-newsletter-audit fundamental. For each newsletter:

• Read the last 3-5 issues to verify content quality and audience alignment
• Check if they already run sponsor content (proof of an established ad program)
• Score on the 1-5 scale across four dimensions: audience overlap, audience size, engagement quality, and ad-program maturity
• Flag newsletters that appear to have inflated subscriber counts (very low engagement relative to claimed size)

4. Calculate cost-efficiency metrics

For every newsletter that scores 12+ out of 20 on the audit, calculate:

• Effective CPM: (price / subscribers) * 1000
• Cost per estimated open: price / (subscribers * open_rate)
• Cost per estimated click: price / (subscribers * open_rate * estimated_ctr) — use 2% CTR as default for sponsored blurbs if no data available
• ICP density score: Multiply the audience overlap score (1-5) by the audience size score (1-5). Higher means more ICP-matched eyeballs per dollar.

5. Rank and build the shortlist in Attio

Use the attio-lists fundamental to create a list called "Newsletter Sponsors — {date}". Add the top 10-15 newsletters ranked by: ICP_density_score / effective_CPM (maximize ICP exposure per dollar). Include fields:

• Newsletter name and URL
• Publisher company name
• Estimated subscribers and open rate
• Price per placement and effective CPM
• Audit score (out of 20)
• ICP density score
• Ad sales contact name, email, and LinkedIn
• Marketplace source (Paved, direct, etc.)
• Status: "Researched" (initial state)

6. Flag competitive intelligence

While auditing newsletters, note which competitors are already sponsoring them. Use Who Sponsors Stuff (whosponsorsstuff.com) to check sponsor history. Newsletters where competitors advertise are validated channels — their audience responds to products like yours. Record competitor names on each newsletter's Attio record.

Output

• Ranked shortlist of 10-15 newsletters ready for paid sponsorship in Attio
• Each newsletter scored on audience quality, ICP overlap, and cost-efficiency
• Ad sales contact info for each newsletter
• Competitive intelligence on who else sponsors these newsletters
• Ready for newsletter-rate-negotiation fundamental and newsletter-sponsor-booking drill
