Beehiiv's Ad Network (The Fast Track)

How it works:

Beehiiv connects you to their ad network
Advertisers pay per 1,000 impressions (CPM)
You get 50% of the CPM, Beehiiv takes 50%
Payouts happen monthly

Math example: If your newsletter gets 50K impressions/month at a $10 CPM:

Total ad revenue: 50 × $10 = $500
Your cut (50%): $250/month

Why Beehiiv wins here:

Monetizes at 100 subscribers (impressive)
No paywall needed — free subscribers = revenue
CPM scales with niche (finance/tech get higher CPM than general interest)
Boosts program adds referral income on top

The ceiling: Most creators hit $500-2,000/month in ad revenue at 10K+ subscribers. Top 1% hit $5K+/month with 50K+ subscribers and premium niches (finance, tech).

Substack's Model (The Paywall Approach)

How it works:

You set up paid subscription tiers
Substack takes 10% of subscription revenue
You keep 90%
Payouts via Stripe monthly

Math example: If 100 subscribers pay $10/month:

Total revenue: 100 × $10 = $1,000
Substack's cut (10%): $100
Your take: $900/month

Why Substack wins here:

Higher per-subscriber value ($5-20/month typical)
Cleaner economics (you know exactly what you'll make)
No dependency on advertiser CPM rates (which fluctuate)
Paying subscribers are more engaged

The ceiling: Realistic: $1,000-5,000/month at 100+ paying subscribers. Top creators: $10K-50K/month with 500+ paying subscribers.

Head-to-Head: Starting From Scratch

You have 5,000 free subscribers. No paying tier yet.

Beehiiv Ad Network:

Assume 20% open rate = 1,000 impressions/send
2 sends/week = 2,000 impressions/week = ~8,000/month
At $8 CPM (mid-range): 8 × $8 = $64 × 50% = $32/month

Substack Paywall:

Assume 3% conversion to paid ($10/month tier)
5,000 × 3% = 150 paying subscribers
150 × $10 × 90% = $1,350/month

Winner at 5K subscribers: Substack by 40x

But here's the catch: getting 3% of your audience to pay is hard. Realistic conversion is 0.5-2%. At 0.5%, you'd have 25 paying subscribers = $225/month. Then Beehiiv's ads start looking competitive.

The Hybrid Play (The Best Path)

Use both:

Beehiiv for ad network revenue — monetize your entire free list
Substack Boosts — get paid for promoting other creators' newsletters (referral income)
Premium tier — offer a paid tier to your most engaged readers

Real scenario: 10K subscribers, 1.5% paid tier (150 paying), Beehiiv ads at $10 CPM:

Ad revenue: (10,000 impressions × $10 CPM / 1,000) × 50% = ~$50/month
Paid subscriptions: 150 × $10 × 90% = $1,350/month
Total: $1,400/month

The Real Talk

If you have an audience already: Substack's paywall wins. People will pay for good content; the question is conversion rate.

If you're building from 0: Beehiiv's ad network gets you revenue while you build. No pressure to convert people; you monetize the free subscribers.

If you're serious: Use Beehiiv (or SubStack) for distribution, run the ad network (or paywall), and build your own audience on owned channels (email list, Substack, personal site). That's where the real money lives.
