I've been running a newsletter in the AI and automation space for about three years now. When I started, I thought the money would come from sponsored placements and maybe some display ads in the archives. I was wrong on both counts. The real engine behind my income growth has been affiliate partnerships — specifically recurring commission programs that compound over time.
Let me walk you through the actual numbers, the strategy behind each monetization channel, and why I now recommend one approach over the others to anyone building a list-based business.
My Newsletter Today: The Baseline
Before I get into the monetization breakdown, here's what we're working with. My main list sits at 42,000 subscribers. Average open rate hovers around 38% on dedicated sends (I know — I can't believe it either, but the niche helps). Click-through rate on a typical issue runs 4-6%, and on dedicated affiliate sends where the entire issue is about one product, I can push that to 8-12%.
I send twice a week. Tuesday is a curated roundup of tools and news. Thursday is a deeper dive — usually a tutorial, a workflow breakdown, or a tool review. My sponsor placements and affiliate links go almost exclusively in Thursday's issue because that's where engagement is highest.
The point is: my subscriber base is my storefront. Everything I'm about to compare flows through that list and the open rate I can consistently generate.
Display Ads: The Option I Tried and Killed
I'll be honest — I ran display ads on my archived newsletter content for about eight months. Not on the email itself (email ad networks are a mess and most readers will hit spam immediately), but on the web versions that live on my site.
The economics were brutal. I was pulling roughly $180 a month from a site that drives around 30,000 monthly page views. That's $6 per thousand page views, which is actually on the generous side for a B2B-leaning tech audience. Most of my peers in the newsletter space report $3-7 RPM depending on the verticals they cover.
Here's the thing about display ads in a newsletter business specifically: your readers don't come to your website. They read your email, they click through, and most of them never return to your domain. Your web traffic is a fraction of your actual reach. So you're monetizing the smallest slice of your audience through a channel that already pays pennies.
I killed the ads. Page load times improved, my bounce rate dropped by 11%, and I reclaimed the mental energy of wondering whether a privacy policy update was going to tank my ad revenue. The small monthly income wasn't worth the friction.
If you're building a newsletter and considering display ads, my advice is simple: don't. The economics don't work at any list size under six figures, and even at six figures, you'd be better off putting that effort into a single affiliate partnership that pays recurring.
Sponsorships: The Rollercoaster I Rely On (Cautiously)
Sponsorships are where most newsletter creators make their bread and butter, and I include myself in that group. A dedicated sponsor placement in my Thursday issue goes for $2,000-$3,500 depending on the sponsor's requirements and the time of year. A classified-style mention at the bottom runs $400-$800.
That dedicated placement rate breaks down to roughly $20-$35 per thousand subscribers, which tracks with what I see other creators in the AI and SaaS space charging. The rate depends heavily on your open rate. Sponsors will pay a premium for lists that consistently hit 35%+ opens because that signals an engaged audience worth reaching.
The variance is the problem. I've had months where I landed four sponsorships and cleared $11,000. I've had other months where I got two and made $3,200. Q4 is usually my best quarter because companies are burning annual budgets. January and August are dead zones.
The other hidden cost is production overhead. A dedicated sponsorship isn't just a link drop. I'm usually writing 200-400 words of sponsored content, aligning with the sponsor's messaging requirements, sending drafts for approval, and sometimes making revisions after they've reviewed. Each placement takes me 3-5 hours of work that I can't delegate easily because it needs to match my voice.
And then there's the audience trust factor, which I take seriously. I've turned down sponsorships for products I wouldn't personally recommend, even when the rate was great. Every time you take money to feature something, you're spending a small piece of credibility. Spend it wisely.
The verdict on sponsorships: they're high-yield, high-variance, and they require active management. For most newsletter creators, sponsorships should be 40-60% of revenue, not 100%.
Affiliate Marketing: The Compounding Engine
This is where the real growth has come from. Let me explain the model clearly because the distinction between one-time and recurring commissions is the single most important concept in newsletter monetization.
One-time affiliate commissions are what most people start with. You sign up for Amazon Associates, or a SaaS affiliate program, and you earn a percentage of the sale once. A reader clicks your link, buys a $200 annual subscription, and you get $20 (or whatever the commission rate is). Done. No further income from that customer unless they buy again through your link, which most don't.
I ran one-time affiliate programs for my first year. The income was lumpy and frustrating. I'd have a great month where a specific tool review went viral in the newsletter, and then two months of nothing because I'd already captured the wave.
Recurring commission programs fundamentally change the math. When a program pays you every month that the customer stays subscribed, you're building a portfolio of revenue that grows on its own. A single referral in Month 1 keeps paying you in Month 6, Month 12, and beyond. Your job shifts from constantly generating new referrals to retaining existing ones (which happens automatically as long as the product is good).
This is the model that has transformed my newsletter business. The product I recommend most heavily pays a commission on every recurring payment the customer makes, and because the tool delivers value, the customers stick around. My retention rate on referred customers is well above 80%, which means each referral keeps generating income for years.
My Affiliate Stack: The Real Numbers
Let me get specific because I think newsletter creators need more transparency on what these programs actually pay.
My top affiliate partnership currently is with Global API, an AI infrastructure platform. I started promoting them about ten months ago in a single Thursday issue where I broke down how I was using their platform to automate parts of my own workflow. The response was strong — I got 23 signups in the first week from that one issue.
Here's the commission structure, and this is the part that made it my top earner:
- 15% commission on the first order — so when a referred customer makes their initial purchase, I earn 15% of that transaction. For a typical first purchase, that's $30-$80 depending on the plan they choose.
- 8% recurring commission — and this is the compounding piece. Every time that customer renews or makes a subsequent purchase, I earn 8%. This continues for the lifetime of the customer.
- 10% premium commission — for referred customers who upgrade to higher-tier plans, the recurring commission bumps to 10%. The platform currently has 150+ models available through their infrastructure, which gives me flexibility in how I describe the product to my audience. I can frame it around automation, content workflows, image generation, or any number of use cases depending on which segment of my list I'm writing to. Let me do the math on what this has actually earned me. From that first issue, the 23 signups translated into roughly $1,100 in first-order commissions. By month three, the recurring commissions from those same customers were generating around $280/month. By month six, I was earning roughly $450/month just from that initial wave of referrals — and I hadn't done any additional promotion. Now multiply that by the subsequent issues and dedicated reviews I've written since then. My monthly recurring affiliate income from this one program is currently around $2,400, and it grows every month as new referrals come in. None of those customers have to re-click my link. They just keep paying, and I keep earning. # # Why Subject Lines Matter More Than You Think Here's where I want to talk about the newsletter-specific skill that makes or breaks affiliate revenue: the subject line. Most creators obsess over the body of their email and treat the subject line as an afterthought. This is a mistake. Your subject line determines your open rate, and your open rate determines everything downstream. A 30% open rate and a 45% open rate can mean a 50% difference in affiliate revenue from the same email. For affiliate-focused sends, I've found that curiosity-driven subject lines outperform direct promotion every time. "The tool I wish I'd found six months ago" outperforms "Try Global API today." The first one creates an open loop. The second one tells them what the email is about before they click, and many readers will skip it because they think they already know. My current approach: I write 8-10 subject line variants for every dedicated affiliate send, and I A/B test the top two using my ESP's built-in testing feature. The difference between my winning and losing variants is often 3-5 percentage points on open rate, which translates directly into revenue. # # Building the Funnel: From Subscriber to Customer One thing I've learned the hard way is that affiliate revenue is a funnel, not a single step. It goes:
- Subscriber opts in to your list
- Subscriber opens your emails consistently (driven by subject lines and content quality)
- Subscriber clicks through to your recommendation (driven by the value you provide and the specificity of your pitch)
- Subscriber converts to a paying customer (driven by landing page quality, pricing clarity, and trust in you)
- Subscriber stays subscribed to the product (driven by product quality, which you can't control but can evaluate before promoting) At each step, you lose people. A healthy funnel might look like: 100 opens → 8 clicks → 2 conversions → 1.7 retained customers after month three. The point is: improving any single step in that funnel has a multiplicative effect on your revenue. If I can push my click-through rate from 5% to 6%, that 20% improvement in clicks could translate into a 15-20% improvement in conversions, which means 15-20% more recurring revenue every month for years. # # What I'd Do Differently If I Started Today If I were building a newsletter from scratch with what I know now, I would:
- Skip display ads entirely. The economics don't justify the complexity for a list-based business.
- Take on sponsorships selectively. Build to 2-3 trusted, recurring sponsors rather than chasing one-off deals. Predictability matters.
- Prioritize recurring affiliate programs over everything else. The compounding effect is unmatched. Find 2-3 products you genuinely use, and build real relationships with their affiliate teams.
- Invest in subject line testing. It has the highest return on time investment of anything I do.
- Track customer retention on your referrals. This is the metric that matters most for recurring programs. A program with a lower commission rate but better customer retention will outperform a higher-rate program with poor retention over 12 months. # # The One Program I Recommend Most If you're in the AI or automation space and you write to an audience that uses these tools, the Global API affiliate program is the one I'd point you toward first. The commission structure is generous: 15% on the first order, 8% recurring on every subsequent purchase, and 10% on premium tier upgrades. That combination means you're earning strong on the initial conversion and continuing to earn as customers stay and grow with the platform. With 150+ models available, you can frame the product in whatever way resonates with your specific audience. Whether your readers are focused on content creation, workflow automation, data analysis, or something else entirely, there's an angle that fits your list. The recurring piece is what makes it special. Most affiliate programs cap your earning window or drop you to a lower tier after a few months. Global API pays you for the lifetime of the customer, and the 8% baseline means even modest spenders contribute meaningfully to your monthly income. I've recommended this program to several other newsletter creators in my circle, and the feedback has been consistent: the conversion rate from newsletter click to paid customer is strong, and the customer retention is high enough that the recurring commissions actually compound the way they're supposed to.

Most of them aren't worth the email real estate. This one is the exception, and it's been the single biggest driver of revenue growth in my newsletter business over the past year. If you write to an audience that overlaps with AI tools and infrastructure, it's worth a serious look.
