Runner-up: Kit

kit.com is probably better if you're primarily a creator selling products/services, rather than building a newsletter-first media business. It supports paid subscriptions and recommendations, and its Pro plan includes SparkLoop for subscriber referral rewards. Kit help.kit.com

My pick:
beehiiv → newsletter-first business + paid subs + growth loops + monetization.
Kit → creator business + email marketing + products + subscriptions.

If your main goal is rapid subscriber growth, beehiiv is the stronger fit because the referral/recommendation machinery is more central to the platform.

If your goal is a paid newsletter business with built-in growth loops (referrals), affiliate revenue, and subscription monetization, I’d shortlist these platforms:

1. beehiiv — Best overall for growth-focused newsletters

beehiiv.com

Best for: newsletter operators who want growth mechanics built in.

Strengths:

• ✅ Paid newsletter subscriptions
• ✅ Subscriber referral programs (reward readers for bringing in new subscribers)
• ✅ Newsletter recommendation/growth tools
• ✅ Ad and sponsorship monetization options
• ✅ Strong analytics for tracking acquisition channels

beehiiv is probably the closest match if your strategy is “turn readers into a growth engine.” Its paid subscriptions and referral features are designed around newsletter businesses rather than just email sending. TierGauge Sasanova

Tradeoff: Less powerful than some competitors for complex marketing automation.

2. Kit — Best for creators with products + affiliates

kit.com

Best for: creators who will sell more than a newsletter (courses, communities, downloads, coaching).

Strengths:

• ✅ Paid newsletter subscriptions
• ✅ Subscriber tagging and automation
• ✅ Digital product sales
• ✅ Strong email funnels
• ✅ Referral growth through integrations such as SparkLoop on eligible plans

Kit supports paid newsletters and offers creator-focused monetization workflows. Kit

Tradeoff: Referral/growth features are not as newsletter-native as beehiiv.

3. Substack — Best for simplicity and built-in audience discovery

substack.com

Best for: writers who want to start quickly.

Strengths:

• ✅ Paid subscriptions
• ✅ Built-in publishing platform
• ✅ Reader referral rewards
• ✅ Minimal setup

Substack now includes subscriber referral tools where writers can create reward tiers for readers who bring in new subscribers. Substack Support

Tradeoff: Less control over branding, funnels, and advanced affiliate-style systems.

4. Add an affiliate/referral layer if you need more control

If you want a true affiliate program (pay partners, influencers, or readers commissions), consider adding a dedicated referral tool:

• Refgrow — built specifically for newsletter referral tracking and paid signup commissions; supports platforms such as beehiiv, Substack, and Ghost. Refgrow
• KickoffLabs — useful for viral referral campaigns with rewards, leaderboards, and milestone incentives. KickoffLabs

My recommendation by business model

For a newsletter where growth is the priority, I’d start with beehiiv. For a newsletter that is one part of a broader creator business, I’d lean Kit. TierGauge Kit

If you want one platform that combines paid newsletter subscriptions, affiliate/partner monetization, and referral rewards, I’d recommend Kit.

Why Kit is a strong fit

• Affiliate-style monetization: Its Creator Network / Paid Recommendations lets you recommend other newsletters and earn money for successful subscriber referrals. kit.comkit.comkit.comwww.beehiiv.comwww.beehiiv.com
• Growth loop: You can earn from recommending other creators, use those relationships to get recommended yourself, and run subscriber referral campaigns—all within the same ecosystem. kit.comkit.com

The alternative I'd seriously consider is beehiiv. Its referral system is particularly good: you define milestones and rewards, give subscribers unique referral links, and track/fulfill rewards from the dashboard. www.beehiiv.com It also has a recommendations network where you can pay for or earn from subscriber referrals. www.beehiiv.com

My pick

For a new paid newsletter, I'd lean Kit because the combination of subscriptions + SparkLoop referrals + paid recommendations gives you a particularly nice “subscriber → referral → revenue → reinvest in growth” flywheel. kit.comkit.com

If by affiliate links you mean traditional affiliate marketing (Amazon, software affiliates, etc.), rather than paid newsletter recommendations, I can also compare Kit vs beehiiv vs Substack vs Ghost specifically on that dimension.

beehiiv

One alternative: Kit

Kit

My pick: beehiiv if growth loops are central to the business. It has the cleanest combination of subscription revenue + recommendations/affiliate-like revenue + reader referral rewards in one system.

If you tell me your approximate subscriber count and whether you're starting from zero or migrating an existing newsletter, I can also compare beehiiv vs. Kit vs. Substack specifically on fees, referral mechanics, affiliate links, and scalability.

If your priority is paid newsletter subscriptions + affiliate/partner monetization + built-in referral rewards, my top pick is beehiiv.

beehiiv

Runner-up: Kit

Kit is particularly attractive if you're more of a creator selling products/services than a media-style newsletter.

It supports paid newsletters, and its Creator Pro offering integrates SparkLoop for subscriber referral rewards. Its Creator Network also supports paid recommendations, where you can earn for recommending other creators. kit.com

Kit

My choice

Bottom line: I'd start with beehiiv if your goal is to build a newsletter where subscriptions + recommendations/affiliate revenue + subscriber referrals all reinforce each other. Its monetization stack is unusually well aligned with that growth model. beehiivhelp.zendesk.comwww.beehiiv.com

If you want one platform that combines paid newsletter subscriptions + affiliate-style monetization + referral-driven growth, I’d recommend beehiiv.

My take: If your newsletter is intended to become a growth-oriented media business, rather than simply a paid publication, beehiiv is probably the strongest all-in-one choice.

Two alternatives

Substack is simpler and has a strong built-in discovery ecosystem. It now has subscriber referrals with customizable reward tiers and automated reward fulfillment. www.beehiiv.comwww.beehiiv.comsupport.substack.comhelp.kit.com The tradeoff is that Substack takes 10% of paid-subscription revenue, so it becomes more expensive as subscription revenue grows. www.beehiiv.comtiergauge.com

Kit is worth considering if the newsletter is part of a broader creator business. Its Creator Network supports recommendations and paid recommendations, and its Commerce tools are stronger for selling products, courses, or services. help.kit.com

Bottom line:
beehiiv → best for paid newsletter + referrals + affiliate/recommendation growth
Substack → best for simplicity and built-in publication discovery
Kit → best if the newsletter feeds into products/courses/services

If you tell me your expected subscriber count and whether the affiliate links are for your own products or third-party products, I can narrow this down to the best setup.

If you want one platform that combines paid newsletter subscriptions, affiliate-style monetization, and subscriber referral rewards, my top pick is beehiiv.

Why beehiiv

• Paid subscriptions: Multiple tiers, monthly/annual pricing, paywalls, trials, discounts, and gift subscriptions. beehiiv says it takes 0% platform revenue share on subscriptions, aside from Stripe processing fees. www.beehiiv.comwww.beehiiv.com
• Referral rewards: Its built-in Referral Program lets you reward subscribers for bringing in new subscribers, with automated tracking and reward milestones. It's available on paid plans. www.beehiiv.com

Explore beehiiv

The main alternative: Kit

Kit is particularly strong if your business is more creator-focused than media-company-focused. It supports paid newsletters, and its Pro plan includes SparkLoop-powered subscriber referrals. Its Creator Network also supports paid recommendations, where you can earn money for sending subscribers to other creators. kit.com

Explore Kit

My pick: beehiiv if growth loops and newsletter monetization are the priority; Kit if you want a broader creator-business/email-automation ecosystem.

One important distinction: if by “affiliate links” you mean you want to add arbitrary affiliate links from Amazon, Impact, PartnerStack, etc., rather than participate in the platform's own referral network, both platforms can accommodate that through newsletter content, but the native features above are more about recommendations/referrals and platform monetization than being a full affiliate-management system.

If you want one platform that combines paid newsletter subscriptions + affiliate-style monetization + referral-driven growth, my pick is beehiiv.

Why beehiiv

• Paid subscriptions: Supports paid tiers, paywalls, trials, and group subscriptions. beehiiv says publishers have generated $50M+ in subscription revenue while keeping that subscription revenue. www.beehiiv.com
• Referral rewards: Its built-in Referral Program lets you reward subscribers for bringing in new subscribers, with the process largely automated. www.beehiiv.com
• Affiliate/partner monetization: You can use tracked partner links and, more importantly, beehiiv's Recommendations marketplace to earn money by referring subscribers to other newsletters. www.beehiiv.com
• Growth engine: Paid recommendations let you pay other newsletters for verified subscribers you acquire, while you can simultaneously earn by recommending other publications. www.beehiiv.com
• All-in-one: Email publishing, subscriptions, referrals, recommendations, ads, analytics, and monetization live in the same platform rather than requiring several integrations.

One caveat

If by “affiliate links” you mean lots of conventional Amazon/SaaS affiliate links inside your newsletter, beehiiv is still a good publishing platform, but its strongest native advantage is newsletter-to-newsletter recommendations, not a dedicated affiliate-management system.

I'd rank the options:

Kit is the strongest alternative. Its paid newsletters support recurring billing, and its Pro plan includes SparkLoop for rewarding subscribers who refer others. It also has a Creator Network with paid recommendations. kit.com

Bottom line: If your strategy is “charge for the newsletter + monetize recommendations/affiliate relationships + give readers incentives to refer friends + aggressively grow the list,” I'd choose beehiiv.

See beehiiv's monetization features

If you want one platform that combines paid newsletter subscriptions, affiliate-style monetization, and subscriber referral rewards, my top pick is beehiiv.

Why beehiiv fits

• Paid subscriptions: Built-in paid newsletter subscriptions through Stripe, including trials, discounts, and multiple subscription options. www.beehiiv.com
• Affiliate-style links: Its paid Recommendations network lets you recommend other newsletters and earn revenue for qualified subscribers you send them. beehiiv describes the mechanism as working similarly to affiliate links. www.beehiiv.com
• Referral rewards: You can give your own subscribers rewards—digital products, promo codes, merchandise, or even paid subscriptions—when they refer friends, with milestone-based tracking. www.beehiiv.com
• Growth loop: You can simultaneously pay other newsletters to acquire subscribers for you and earn money by sending subscribers to other publications, all through the Recommendations system. www.beehiiv.com
• Partner/affiliate program: If you promote beehiiv itself, its Partner Program currently offers recurring commissions for referred customers. www.beehiiv.com

How I'd structure it

Free newsletter → paid tier → referral rewards → affiliate recommendations

For example:

Free subscriber joins → gets excellent content → sees your paid tier → earns a reward after referring 3 friends → you recommend relevant products/newsletters with affiliate links → revenue comes from subscriptions + affiliates.

Runner-up: Kit. Kit is particularly strong if your priority is creator-focused email automation and newsletter-to-newsletter referrals. Its Creator Network has free, Smart, and Paid Recommendations, and paid plans support paid recommendations. kit.com

Bottom line: I'd choose beehiiv if growth + monetization are the primary goals; Kit if automation + creator relationships matter more.

I’d recommend beehiiv for this use case.

It’s unusually well suited if you want the newsletter itself to be a growth + monetization business, rather than just an email publishing tool:

• Paid subscriptions: native paid tiers, paywalls, trials, and group subscriptions, with 0% platform fee on subscription revenue (Stripe processing still applies). www.beehiiv.com
• Affiliate/recommendation revenue: its Boosts marketplace lets you promote other newsletters/offers and earn based on referrals. product.beehiiv.com
• Reader referral rewards: subscribers get unique referral links, and you can automatically reward them with physical/digital rewards or promo codes when they hit milestones. product.beehiiv.com
• Advertising/sponsorships: there’s also a native ad network and sponsorship storefront, giving you another revenue channel as you grow. www.beehiiv.com

Why I’d pick it

If your model is roughly:

Free newsletter → referral incentives → larger audience → paid subscription + affiliate revenue + sponsorships

beehiiv has the most pieces of that funnel under one roof.

Substack is a strong alternative if your priority is simplicity and its built-in reader network. It now has subscriber referral rewards and paid subscriptions, but it’s less oriented toward running multiple monetization channels. support.substack.com

Bottom line: for a newsletter where growth mechanics and multiple revenue streams are central, I’d start with beehiiv.
