If you write a newsletter, your readers opened the email because they trust the byline. That trust is the thing that keeps your open rate above 40% when most newsletters sit at 22%. It is also the thing you instinctively protect when you see a "monetize your list" thread on Twitter and feel your shoulders tighten.
This piece is for writers who would rather leave money on the table than sound like they are reading from a media kit. The good news is you do not have to. Done properly, affiliate income can slide underneath your existing writing without you rewriting a single sentence in a different voice — and it can compound into a meaningful revenue line without ever interrupting a reader mid-paragraph.
Oakgen.ai pays 25% commission on every subscription for the first 6 months the referred reader stays subscribed. The full mechanics are in the affiliate program explainer, but the short version is: you place one link, the right readers convert, and you get paid every month of their first six billing cycles. No gimmicks, no tiers, no quarterly goalposts. This post is about the placement, not the program.
The Trust-First Model (Why Most Newsletter Affiliates Flop)
Most newsletter affiliate sections fail for the same reason most sponsored Instagram posts fail: they read like they were pasted in from somewhere else. The voice changes, the cadence speeds up, the adjectives thicken, and suddenly the reader is looking at an ad dressed as an essay.
Readers notice this faster than you think. They do not always unsubscribe — but they stop clicking, stop forwarding, and quietly stop believing the next recommendation you make. The damage is invisible and compounding.
The trust-first model inverts the default. Instead of asking "how do I fit an affiliate link into this newsletter," you ask "where in the trust architecture of my newsletter does a recommendation naturally belong, and which tool is honest enough for me to recommend it without flinching?" If those two answers do not align, you skip the placement. That is the whole model.
When they do align — when you genuinely use a tool and a reader could benefit from it — the placement disappears into your voice because it already was your voice. You are not selling. You are telling someone what is on your desk.
Three Placement Patterns That Preserve Voice
There are only three placements that reliably work for newsletter writers. Everything else is a variation on these.
Pattern A: The sidebar or masthead "tools I use" link
A single-line placement in your masthead, footer, or author bio block. Something like Tools I use to make this newsletter → followed by a link to a page on your own domain (or a Notion page, or a simple landing page).
When it fits: every newsletter. This is the lowest-friction placement in existence. It is always-on, it never interrupts the writing, and readers who are curious will click it on their own time.
Typical conversion: low absolute numbers, but high intent. Maybe 0.2–0.5% of opens click through to the tools page. Of those, 3–8% end up buying something. You will not get rich on the sidebar alone, but you will never have to apologize for it either.
Pattern B: The inline aside within a piece
A parenthetical, usually one or two sentences, dropped inside a larger essay. Something like: "(I wrote the first draft of this piece with an AI I actually like — Oakgen — which lets me generate cover images and voice-overs from the same workspace. Affiliate link if you want to try it.)"
When it fits: essays where the tool was genuinely involved in making the piece. Process posts, behind-the-scenes newsletters, "how I made this" breakdowns. It feels dishonest if the tool was not part of the workflow.
Typical conversion: highest of the three patterns when done well. The placement inherits the authority of the piece around it. On a good essay, 4–8% of readers click, and 10–15% of clickers convert. On a forced inline, you get neither — and you sound like a radio ad.
Pattern C: The dedicated "tools I use" page
A standalone page on your site or newsletter, linked from every issue via a short footer line ("My full stack is here") and occasionally referenced in the body when it is relevant. Each tool gets a paragraph — what it is, why you use it, what it replaced, what it does not do well.
When it fits: any newsletter with a niche where readers regularly ask "what do you use for X?" Tech newsletters, writing newsletters, creator newsletters, finance newsletters, design newsletters — all benefit disproportionately from this page.
Typical conversion: the highest lifetime yield of any placement, because the page compounds. Every new reader who joins the list eventually finds it. Every old reader who gets curious revisits it. One well-written "tools I use" page will out-earn a hundred inline drops over five years.
The dedicated "tools I use" page is the single highest-ROI asset a newsletter writer can build for affiliate income. It is also the one most writers never build because it feels less like writing and more like bookkeeping. Spend one afternoon on it. You will earn on it for a decade.
Disclosure Copy That Doesn't Kill Conversion
The FTC requires you to disclose affiliate relationships. It does not require you to sound like a lawyer. The worst-performing disclosures are the ones that scream — bold, all-caps, aggressively legalistic — because they signal to the reader that something shady is about to happen. The best-performing disclosures are short, specific, and conversational.
Three phrasings that are both compliant and human:
- "Some links below are affiliate links — if you buy through them I get a small recurring cut. I only link to tools I actually pay for and use myself."
- "Full disclosure: affiliate link. Oakgen pays me a percentage of your subscription if you sign up through it. I would recommend it regardless — it is on my desk either way."
- "This is an affiliate link. You pay the same price; I get a commission. If the recommendation is wrong for you, please do not click it for my benefit."
Notice what all three have in common: they are written in the same voice as the rest of the newsletter. They do not flinch, they do not over-explain, and they respect the reader's ability to make the decision themselves. That last line in option three — "please do not click it for my benefit" — counterintuitively increases conversion, because it signals that you are not desperate for the click.
What Works vs. What Flops — Four Annotated Examples
Let us look at four real-shaped examples. Two that read as honest recommendations, two that read as pasted-in promotions.
Good example #1:
I have been drafting these Monday essays with Oakgen for the last six weeks. It generates the cover image, the headline variants, and the voice-over for the audio version in the same tab. Price-wise it is a wash against what I was stitching together before, but mentally it is half the tax. If you are curious: [affiliate link], it pays me if you subscribe.
Why it works: specific time frame ("six weeks"), specific jobs the tool does ("cover image, headline variants, voice-over"), honest about the economics ("a wash"), clear disclosure. Reads like the rest of the newsletter.
Good example #2:
(Process note: the portrait at the top of today's piece was generated in Oakgen — affiliate link, I get a cut if you sign up. I drew the brief, the tool drew the picture.)
Why it works: parenthetical placement, single line, the tool was actually involved in the piece, and the disclosure is matter-of-fact. The phrase "I drew the brief, the tool drew the picture" is in the writer's voice.
Bad example #1:
Attention creators! Tired of juggling 5 different AI tools? Oakgen.ai is the ALL-IN-ONE creative studio you have been waiting for. With unlimited images, videos, music, and TTS, Oakgen is the industry leader in AI content generation. Sign up today with my exclusive link and unlock your creative potential!
Why it flops: every sentence is a cliché. "Attention creators," "tired of juggling," "industry leader," "unlimited," "unlock your creative potential" — none of these phrases would ever appear in the writer's actual newsletter. The reader's internal voice-detection flags it as foreign. Click-through craters. More reading on why this tone backfires is in how to promote an AI tool without sounding cringe.
Bad example #2:
Also — Oakgen is great. Check it out. [link]
Why it flops: the opposite problem. Too thin to be useful, too unattached to the surrounding piece, no disclosure, no reason to click. Reads like an afterthought, which signals to the reader that it is an afterthought — probably a paid one. A two-word recommendation with no context is worse than no recommendation at all, because it trades trust for nothing.
The Compounding Effect (Do The Math)
Here is the math that most newsletter writers miss.
Pick a middle estimate. A "tools I use" page on a mid-sized newsletter gets 3 signups per month across all its linked tools. Oakgen pays out an average of $5 per signup per month (most referrals land between the Basic and Pro plans, averaging around there). That is:
- Month 1: 3 new subscribers × $5 = $15/month recurring
- Month 6: roughly 15 active referrals × $5 = $75/month commission (all of the first-six-months' referrals are still inside their 6-month window)
- Month 12: roughly 18–22 active referrals inside their 6-month window × $5 ≈ $90–$110/month. The earliest cohorts have rolled off the window, but if you keep publishing, new cohorts keep rolling in to replace them.
- Year 2 running total: in the neighborhood of $1,400–$1,900 earned across the year, depending on whether your publishing cadence holds
That is from one page, one tool, one newsletter, with no ad drops, no sponsorships, no disruptive placements. It doesn't compound indefinitely — each referral's 6-month window is fixed — but it stacks as long as you keep publishing, because every new issue sends a trickle of new traffic to that same evergreen page, and every fresh referral starts a new 6-month stream.
Compare that to ten disruptive ad drops. Ten ad drops in a year is roughly one every five weeks. Each one costs you a little trust, some unsubscribes, and a conversion rate that decays as readers learn to skim past them. You might make more in raw dollars in year one, but you will also burn the list you spent years building. The "tools I use" page does the opposite: every month it earns more than the month before, and readers respect you slightly more for having one.
Earn 25% recurring on every referral.
Share Oakgen, get paid every month they stay.
Oakgen Setup in 10 Minutes
If the math works for you, here is the setup. It takes under ten minutes and you only have to do it once.
- Open /refer — the Commission Terminal. Sign in with the same account you use for Oakgen.
- Grab your unique affiliate link. It is pinned at the top of the dashboard. The 30-day cookie window starts the moment a reader clicks it.
- Decide your placement. For most newsletter writers, start with Pattern C — the dedicated "tools I use" page — and add Pattern A (masthead link) as a permanent fixture.
- Write the page in your actual voice. One paragraph per tool. What it does, why you use it, what you tried before. Include the disclosure in the first paragraph of the page, not the footer.
- Link it from every future issue with a single footer line: "The tools behind this newsletter →"
- When you write a process-heavy essay where Oakgen was genuinely part of the workflow, use Pattern B (inline aside) — one parenthetical sentence, with the disclosure in-line.
- Watch the Commission Terminal. Clicks show up in real time. Signups and commissions settle on a 30-day rolling cycle. Payouts trigger at $10 via PayPal, Wise, or bank transfer.
That is it. You do not need a funnel, a sequence, a webinar, or a pop-up. You need one honest page and the discipline to not ruin it with the wrong voice.
The reader who signed up for your newsletter did so because you sound like you. Keep sounding like you — and let the recurring commission pile up quietly in the background while you write the next issue. When you are ready, the dashboard is at /refer.
