intro.md

Sponsorships are the fastest newsletter monetization — and you don't need 100k subscribers. A 3,000-subscriber newsletter in a commercial niche (B2B, finance, marketing) with a 40% open rate is sponsor-worthy. This prompt builds your media kit and the cold pitch that gets advertiser replies, framed around engagement and audience quality, not just size.

You are a newsletter monetization expert who's brokered hundreds of sponsorship deals. Build my media kit + the cold pitch to land sponsors.

INPUTS:
- Newsletter topic: {{newsletter_topic}}
- Subscriber count: {{subscriber_count}}
- Open rate: {{open_rate}}
- Audience profile (who they are, their job/spending power): {{audience_profile}}

PRODUCE:

1. AUDIENCE-VALUE FRAMING
Reframe my stats around VALUE, not vanity. A small, engaged, high-spending-power audience is MORE valuable than a big disengaged one. Articulate why a sponsor should care about THIS audience ({{audience_profile}}) — what they buy, what they influence.

2. MEDIA KIT (one-pager structure)
- Newsletter name + one-line description
- Audience: {{subscriber_count}} subscribers, {{open_rate}} open rate, + the audience profile (job titles, industries, interests, spending power)
- Why advertisers reach this audience here (vs other channels)
- Ad placements offered (primary sponsor slot, classified, deep-dive sponsored post) + what each includes
- Suggested PRICING (calculate from subscriber count × open rate × a realistic CPM for this niche — B2B $25-50 CPM, broad consumer $15-25; show the math + a starter rate)
- Social proof / past results (placeholder if none yet)

3. SPONSOR TARGET LIST
10 specific TYPES of companies (and example company names) that would want to reach {{audience_profile}}. Group by how warm/likely they are.

4. COLD PITCH EMAIL
A short, sharp outreach email to a prospective sponsor:
- Subject line (specific, not "sponsorship opportunity")
- Open with why THEIR product fits MY audience (shows you researched them)
- The audience value (engagement + profile, lead with quality not just size)
- A specific, low-friction offer (one slot, a clear price or "starting at $X")
- A clear CTA (book a slot / reply for the media kit)
Keep it under 150 words.

5. RATE-CARD LOGIC
How to price as I grow + when to raise rates (after sold-out slots, after a case study).

Lead with audience QUALITY — a focused {{subscriber_count}}-subscriber list at {{open_rate}} can out-earn a huge unengaged one.

Step-by-step playbook

How to actually use this prompt for the best results.

01
Lead with engagement + audience quality, not size
Sponsors pay for attention and buying power, not raw subscriber counts. A 3k-subscriber B2B newsletter at 45% open rate with director-level readers beats a 50k consumer list at 15%. Frame your pitch around who reads and how engaged they are.
02
Research each sponsor before pitching
The cold pitch opens with why THEIR specific product fits YOUR audience. Generic 'want to sponsor?' emails get ignored. Spend 5 minutes per prospect so the first line proves relevance.
03
Price from real CPM math, then offer a starter rate
Use the subscriber × open-rate × CPM math to set defensible pricing, but offer first sponsors a starter rate in exchange for a testimonial/case study. The case study unlocks higher rates with everyone after.
04
Raise rates after sell-outs
When slots sell out or you have a sponsor result to point to, raise the rate. Sold-out inventory is the signal you're under-priced — the rate-card logic tells you when and how much.

Pro tips for better output

›B2B / finance / marketing / dev newsletters command 5-10× the CPM of broad consumer ones — niche commercial audiences are where sponsorship money is.
›Sponsorships are viable from ~2,500 engaged subscribers in a commercial niche — don't wait for 50k; pitch as soon as your open rate is strong (35%+).
›A single sponsor result/testimonial is worth more than any stat — get your first sponsor a great result and use it to close every sponsor after.

$ man faq

FAQ

How many subscribers do I need to get sponsors?

In a commercial niche (B2B SaaS, finance, marketing, dev), ~2,500 engaged subscribers with a 35%+ open rate is enough to land sponsors. Broad consumer niches need more. It's about audience quality and buying power, not raw size — which is exactly how the pitch frames it.

How do I price a sponsorship slot?

Roughly: subscribers × open rate × CPM ÷ 1000. For B2B use a $25-50 CPM, broad consumer $15-25. So 4,000 subs × 45% opens × $40 CPM ≈ $72/send as a baseline — then adjust up for a premium niche. Offer first sponsors a starter rate for a testimonial.
