If you’re starting a newsletter in 2026, the choice is essentially between three platforms: Substack, Beehiiv, and Kit (formerly ConvertKit). They are not the same product. Picking the wrong one is one of the easier ways to waste a year. This guide breaks down which one wins for which type of creator.
Quick Answer
Pick Substack if you want built-in distribution. Pick Beehiiv if you want growth and ad revenue. Pick Kit if you sell digital products. Most beginners are best served by Beehiiv — lowest cost of being wrong.

Substack — Best If You Want Built-In Distribution
Substack is a network as much as a platform. The Notes feed, recommendations between writers, and the Substack app drive real organic growth. If you’re a writer who wants to be discovered by other writers’ audiences, this is the strongest pick.
Trade-off: you don’t really own your list. Substack owns the relationship. Migrating later is possible but painful.
Beehiiv — Best for Growth and Ad Revenue
Beehiiv has built the most aggressive growth toolkit of the three: referral programs, a built-in ad network for sponsorships, recommendation networks, and serious analytics. It’s the platform of choice for creators treating their newsletter as a business from day one.
Trade-off: fewer audience discovery effects than Substack. You bring the audience.
Kit — Best for Creators Selling Products
Kit shines if you sell something — courses, digital products, services. Its automations, tagging, and Creator Commerce features are the deepest of the three. The newsletter is one part of a creator stack, not the whole business.
Trade-off: less newsletter-first culture. The publishing experience is solid but not the headline feature.
Quick Decision Framework
- You want to be a writer and be discovered → Substack
- You want to grow fast and monetize via sponsorships → Beehiiv
- You sell digital products and want email + automation + commerce in one → Kit
What About Migrating Later?
All three let you export your subscribers as a CSV. The difference is what you lose:
- On Substack you lose your audience discovery
- On Beehiiv you lose your referral funnel
- On Kit you lose your automations
Pick like you’ll stay 3 years.
Real Examples
Example 1: A writer launches on Substack. Network effects bring 800 free subscribers in the first month. Eventually moves off Substack after 18 months but takes a 30% subscriber hit.
Example 2: A business creator launches on Beehiiv. Uses the ad network from day one. Hits $2k/month in sponsorships at 4,000 subscribers.
Example 3: A course creator uses Kit because the audience also buys her $499 course. Email automations triple course revenue within 6 months.
The Honest Answer
There is no single winner. There’s a winner for your business model. If you genuinely don’t know which model you’re building, start on Beehiiv — it has the lowest cost of being wrong.
Platform Selection Checklist
- Do I want network effects (Substack) or independence (Beehiiv/Kit)?
- Will I sell digital products to my list?
- Do I want a built-in ad network?
- Will I migrate if I outgrow the platform?
- Have I tried each free tier?
Final Word
Pick the smallest viable setup, ship something this week, and iterate from real feedback.
