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

1. **ICP definition** — Target title, industry, company stage (e.g., "VP of Sales at Series A-C B2B SaaS companies") 2. **Monthly budget** — Rough range for sponsorships (e.g., "$1,000-3,000/month") 3. **Geography** — US only, global, or specific region? 4. **Campaign goal** — Awareness (brand mention) or direct response (signup/demo)? 5. 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 browsing
• `paved.com` for sponsorship marketplace listings
• `swapstack.co` for newsletter ad network
• `sparkloop.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.
