Sponsored Newsletter Finder
Find newsletters your ICP reads, evaluate their audience fit, and produce a ranked shortlist ready for outreach. Cheaper and faster than building your own list from scratch — newsletters already have the trust and the audience.
Best for: Seed/Series A teams with $500-5,000/month to test a paid distribution channel. Not for companies without budget or companies targeting a mass-market ICP.
When to Use
- "Find newsletters I can sponsor to reach [ICP]"
- "What newsletters does my target audience read?"
- "I want to test newsletter sponsorship — where should I start?"
- "Give me a ranked list of newsletters for [industry/role]"
Phase 0: Intake
- ICP definition — Target title, industry, company stage (e.g., "VP of Sales at Series A-C B2B SaaS companies")
- Monthly budget — Rough range for sponsorships (e.g., "$1,000-3,000/month")
- Geography — US only, global, or specific region?
- Campaign goal — Awareness (brand mention) or direct response (signup/demo)?
- Any newsletters you're already subscribed to or know about in this space? (Seeds the search)
Phase 1: Discovery via Web Search
Search for newsletters using multiple angles:
Search Queries to Run
"[ICP industry] newsletter" sponsorship
"[ICP role] newsletter" site:substack.com OR site:beehiiv.com
"best newsletters for [ICP role/industry]"
"[ICP industry] newsletter" "advertise" OR "sponsor"
"[competitor company] newsletter sponsorship" (find where competitors are already advertising)
newsletter directory "[ICP industry]"
Also search curated newsletter directories:
newsletter.directory for category browsingpaved.com for sponsorship marketplace listingsswapstack.co for newsletter ad networksparkloop.co for referral partnerships
Collect: newsletter name, URL, estimated subscribers, topics covered, sponsorship page URL if found.
Phase 2: Evaluate Each Newsletter
For each discovered newsletter, score across 5 dimensions (1-5 each):
Scoring Criteria
| Dimension | 1 | 3 | 5 |
|---|
| Audience match | Unrelated audience | Partial overlap | Direct ICP match |
| Reach | <1,000 subscribers | 5,000-20,000 | 20,000+ |
| Engagement | No open rate data | ~30-40% open rate | 40%+ open rate |
| Niche specificity | Generic business newsletter | Industry newsletter | Role-specific newsletter |
| Sponsor accessibility | No sponsor info found | Inquiry required | Clear pricing / marketplace listing |
Total score: /25. Shortlist newsletters scoring ≥ 15.
Data Points to Find for Each Newsletter
Search for:
- Subscriber count (often on the "About" or "Advertise" page)
- Open rate (sometimes disclosed, often ~40-50% for niche newsletters)
- CPM or flat sponsorship rate
- Audience demographics (if disclosed)
- Past sponsors (who's already buying? = validation)
- Send frequency (weekly, daily, etc.)
For newsletters with no pricing page, estimate CPM from industry benchmarks:
- Micro (<5k subs): $50-150 flat rate
- Small (5k-20k subs): $100-500 flat rate
- Mid (20k-50k subs): $500-2,000 flat rate
- Large (50k+ subs): $1,000-10,000 flat rate
Phase 3: Competitive Intelligence
Check if known competitors are sponsoring newsletters in this space:
Search: "[competitor name]" "sponsored by" newsletter
Search: "[competitor name]" advertisement site:substack.com
If a competitor is sponsoring a newsletter, it's validated audience fit — flag it as high priority.
