ConvertKit vs Beehiiv Affiliate Program 2026: 12-Month Math

50% forever (if you qualify) vs up to 60% for 12 months then nothing. Real dollar scenarios for newsletter and content creator audiences. contains affiliate links

Side-by-side comparison

*Kit's post-12-month recurring applies only to referrals made on or after Jan 1, 2024, and only if you maintain qualifying tier status each year.

The big structural difference most comparisons miss

Most "ConvertKit vs Beehiiv affiliate" articles compare the commission percentages and call it done. That's the wrong frame. The actual decision is about two completely different earnings models.

Kit pays you 50% for 12 months on every referral. Then, if you've referred at least 10 paying customers in a year, you keep earning on those customers forever at a lower rate (10% for Bronze, 15% for Silver, 20% for Gold). The rate drops significantly after month 12, but it doesn't stop.

Beehiiv pays you up to 60% for 12 months. Then it stops, full stop. That customer could stay on Beehiiv for 5 more years and you earn nothing on month 13 onward.

So the real question is: are you building a portfolio of long-term referrals, or are you in rapid-acquisition mode where you're constantly sending fresh referrals every month?

If you send 10 referrals in January and then nothing else for the rest of the year, Beehiiv's higher upfront rate wins. If you send 10 referrals in January, 10 in February, 10 in March, and you keep going while your existing cohorts compound, Kit's structure eventually dominates because your month-1 cohort starts generating post-12-month income just as your month-13 cohort starts generating first-year income.

The cookie math that actually matters

Kit's 90-day cookie is 50% longer than Beehiiv's 60-day cookie. For a certain type of audience, this is the deciding factor, not the commission rate.

Here's the scenario. Someone reads your "best newsletter platforms" comparison in January. They're not ready to commit. They bookmark it. They come back in March and click through to sign up for Kit. At day 75, Kit still credits you. At day 75, Beehiiv would not.

General content creator audiences, bloggers, and podcasters researching their first email platform tend to take weeks or months to make a decision. They compare, they hesitate, they come back. A 90-day window captures that entire decision cycle. A 60-day window cuts off anyone who takes more than two months.

Newsletter-native audiences are different. Someone who already runs a newsletter and is actively evaluating migration options typically decides in days or weeks, not months. For that audience, 60 days is more than enough and the cookie length advantage disappears. Beehiiv's audience is almost entirely this type: newsletter creators who know exactly what they want and move quickly.

Kit's 90-day cookie is 3x longer than the industry's common 30-day standard and 50% longer than Beehiiv's 60 days, which means any audience that takes more than two months to convert will be underattributed on Beehiiv. If your content attracts readers who are still figuring out their newsletter strategy, that attribution gap costs you real money.

Beehiiv's first-click attribution: a hidden tax on your earnings

Beehiiv uses first-click attribution. Kit uses last-click. This matters in practice.

First-click means whoever gets credit for introducing a user to Beehiiv owns the commission, even if the user later clicked multiple affiliate links. If someone discovered Beehiiv through a different creator's post six months ago and then clicked your link last week, you get nothing.

Last-click (Kit) means the most recent affiliate link before signup gets the commission. That favors affiliates who are good at capturing intent close to the decision point, like comparison articles, tutorials, or "how to start a newsletter" guides where readers are actively evaluating.

Neither model is strictly better. But if you're entering a crowded space like Beehiiv promotion, where many established newsletter creators have already introduced their audiences to Beehiiv through their own partner links, first-click attribution means you're competing against every link those readers have already clicked. For Kit, you just need to be the last relevant touch before signup.

Pricing context: what the commissions actually translate to

Commission percentages are meaningless without knowing the plan prices. Here's what each percentage actually earns per customer.

Kit (ConvertKit) Creator plan pricing:

• 1,000 subscribers: $39/month
• 3,000 subscribers: $59/month
• 5,000 subscribers: $89/month
• 10,000 subscribers: $139/month

At 50% commission, a Kit referral on the $39/month Creator plan earns you $19.50/month for 12 months, totaling $234 per referral in year one. At 10,000 subscribers, the same referral at $139/month earns $69.50/month, totaling $834 over 12 months. As that customer grows their list, your commission grows with them. That's the compounding argument for Kit that doesn't get talked about enough.

Beehiiv Scale plan pricing:

• Up to 2,500 subscribers: $49/month ($43/month billed annually)
• Up to 5,000 subscribers: $89/month
• Up to 10,000 subscribers: $109/month
• Up to 25,000 subscribers: $169/month

At 60% commission (Gold tier), a Beehiiv referral on the $49/month Scale plan earns $29.40/month for 12 months, totaling $352.80 per referral in year one. That beats Kit's $234 on the comparable entry plan. But Beehiiv's $49 Scale plan is its full-featured paid offering, while Kit's $39 is just the Creator entry tier. Creators who grow will pay more on both platforms, and Kit's account-growth effect means commissions scale automatically as your referrals' lists expand.

The 12-month math: two real scenarios

Let's run 100 referrals over 12 months under two different audience types. These are new paid conversions, not free plan signups.

Scenario A: Newsletter-native audience

Your audience already knows what a newsletter platform is. They follow creator economy content. They convert within 2 to 3 weeks of clicking. You're at Beehiiv Gold tier (60%) and Kit's base rate of 50%. Assume the average referral pays $49/month on Beehiiv and $39/month on Kit.

Beehiiv (60%, $49/month, 100 referrals, 12 months): 100 x $49 x 0.60 x 12 = $35,280. After month 12, commissions on that cohort stop.

Kit (50%, $39/month, 100 referrals, 12 months): 100 x $39 x 0.50 x 12 = $23,400. Plus, if you hit Bronze status, months 13 onward earn 10% on customers who stay. At 10% on $39/month from 100 customers who stay, that's $390/month ($4,680/year) in year two from the same cohort.

Year one: Beehiiv wins by about $11,880. Year two: Kit starts earning again on year-one referrals. By month 24, Kit's cumulative total ($23,400 + $4,680) reaches $28,080 on the original cohort, closing the gap. If you're also sending new referrals in year two, Kit's compounding becomes significant by year three.

Scenario B: General content creator audience

Your audience is bloggers, YouTubers, and podcasters who are researching email tools for the first time. They take 6 to 10 weeks to decide. Cookie length matters here. You lose roughly 20-30% of potential Beehiiv conversions to the 60-day cutoff that Kit's 90-day cookie would have captured. Assume the same 100 paying referrals on Kit, but only 75 on Beehiiv due to attribution loss from the shorter cookie window.

Beehiiv (60% Gold, $49/month, 75 effective referrals, 12 months): 75 x $49 x 0.60 x 12 = $26,460.

Kit (50%, $39/month, 100 referrals, 12 months): 100 x $39 x 0.50 x 12 = $23,400. Year two Bronze recurring: $4,680.

In this scenario, Kit wins year one too ($23,400 vs $26,460 is close, and by year two Kit's $28,080 cumulative surpasses Beehiiv's $26,460). The 90-day cookie capturing 25% more conversions effectively closes Beehiiv's rate advantage and flips the math. Year two, Kit wins clearly.

Where Beehiiv wins

Beehiiv is the right pick in three situations.

You have a newsletter-native, fast-converting audience. If your readers are already in the creator economy, already thinking about starting or growing a newsletter, and already aware of Beehiiv as a platform, they convert fast. The 60-day cookie is fine. The higher initial rate (up to 60% vs Kit's 50%) means more money in year one. For someone building a newsletter about newsletters, Beehiiv is the obvious primary recommendation.

You're new and prioritize cash flow over long-term compounding. Beehiiv's higher rates in year one mean faster initial earnings. If you're an affiliate early in your career and need revenue now rather than in years two and three, Beehiiv's front-loaded structure delivers more, faster, assuming you can reach Gold tier.

Your audience is specifically switching from Substack, Ghost, or an existing newsletter tool. Beehiiv has earned a strong reputation among newsletter creators migrating from simpler platforms. The Boost network and built-in monetization features are genuinely differentiated. When you're recommending a platform to someone who explicitly wants a newsletter-first product, Beehiiv is an easier sell and converts better because the product fit is clearer.

Where Kit wins

Kit is the right pick in most other situations.

General content creator audiences with slow decision cycles. The 90-day cookie captures readers who take 6 to 8 weeks to commit, a category that describes most general blogging and content marketing audiences. If you write about email marketing broadly, online business, or content creation tools, your readers are comparing multiple platforms and taking their time. Kit's longer attribution window earns you commissions that Beehiiv's shorter cookie would miss entirely.

Long-term recurring income builders. Kit's post-12-month recurring structure (10% to 20% indefinitely for qualifying affiliates) means your existing referral base keeps paying. Beehiiv cuts off at month 12. If you're building an affiliate business over multiple years, Kit's compounding effect becomes enormous. A referral you sent in January 2024 is still earning you 10% every month in January 2027. On Beehiiv, that referral stopped earning you anything in January 2025.

Affiliates who promote across subscriber growth stages. Kit's commissions grow automatically as your referrals grow their lists. A creator you refer at $39/month who grows to 10,000 subscribers and moves to $139/month is earning you $69.50/month in commissions, not the $19.50 you started with. Beehiiv's pricing also scales with subscribers, so this effect exists on both platforms. But Kit's Creator plan pricing at higher subscriber counts is higher than Beehiiv's Scale plan at equivalent tiers, so the dollar amounts tend to be larger on Kit for established newsletter creators.

PartnerStack infrastructure. Kit runs on PartnerStack, one of the most established SaaS affiliate platforms. Real-time reporting, structured dispute resolution, and multiple payout methods including Stripe in addition to PayPal. Beehiiv's in-house platform via Dub is PayPal-only. Not a dealbreaker, but PayPal-only excludes affiliates in certain regions and adds friction for anyone who prefers direct bank deposit.

Honest verdict

Pick Beehiiv if your audience is newsletter-native, converts fast, and you want the highest possible income in year one.

Pick Kit for almost everything else. The 90-day cookie matters more than people give it credit for. The indefinite recurring commissions matter a lot for anyone building a real affiliate business rather than chasing quick wins. And the fact that Kit's commissions scale with your referrals' list growth means your income can compound in ways that Beehiiv's fixed plan prices don't fully match.

I think the honest verdict for most affiliates reading this is: Kit wins. The indefinite recurring structure is genuinely hard to compete with over a 3 to 5 year horizon. Beehiiv wins in year one for the right audience, which is real and worth acknowledging. But most affiliates promoting email tools are not primarily serving newsletter-only audiences, so Kit's broader appeal and longer cookie win more often.

If you do run a newsletter-focused audience and you're confident you can reach Beehiiv Gold tier (60% commission), the year-one math favors Beehiiv. Just go in knowing that your month-12 cohort is your last earning event from that group. Plan your promotion cadence accordingly.
