For most AI professionals starting their first newsletter, Substack is the better choice. It has a built-in recommendation engine that helps with discovery, a simpler setup, and zero cost. Switch to Beehiiv when you hit 1,000+ subscribers and need advanced growth tools, segmentation, and analytics.
This is the most common question aspiring newsletter writers ask, and the answer depends on your stage, goals, and technical comfort level. Both platforms are excellent — neither is a bad choice. But they serve different needs at different stages of growth.
Substack
Substack
Price: Free for free newsletters. 10% of paid subscription revenue if you charge subscribers.
Best for: Writers starting from zero, people who prioritize simplicity, those who want built-in discovery.
Discovery: Substack's recommendation engine is its killer feature. When other Substack writers recommend your newsletter, their subscribers see it. This is the closest thing to organic viral growth available to new writers.
Writing experience: Clean, minimal editor. Great for pure text-based newsletters. Limited formatting compared to Beehiiv.
Analytics: Basic — open rates, subscriber count, top posts. Enough to start, insufficient for optimization at scale.
Limitations: No A/B testing for subject lines, limited segmentation, no custom referral programs, no ad network, basic automation only.
Beehiiv
Beehiiv
Price: Free up to 2,500 subscribers. Paid plans from $39/month for advanced features.
Best for: Growth-focused writers, people who want detailed analytics, those planning to monetize through ads.
Discovery: Beehiiv Boost lets you pay to acquire subscribers through other newsletters, and get paid when you recommend other newsletters. It's a marketplace — more controllable than Substack's organic recommendations.
Writing experience: More powerful editor with better formatting, drag-and-drop sections, and custom HTML blocks. Better for visually complex newsletters.
Limitations: Less built-in social/community features than Substack, steeper learning curve, free tier has Beehiiv branding.
Head-to-Head on What Matters
Getting started speed: Substack wins. You can publish your first issue in under 30 minutes. Beehiiv takes 1-2 hours to set up properly with custom branding and settings.
Organic discovery: Substack wins significantly. The recommendation network is the most powerful growth tool available to small newsletters. Beehiiv's Boost is effective but costs money.
Growth tools at scale: Beehiiv wins. A/B testing, referral programs, automations, and segmentation become essential once you pass 1,000 subscribers. Substack simply doesn't offer these.
Monetization flexibility: Beehiiv wins. Ad networks, paid sponsorship management, and more pricing options give you more ways to generate revenue.
Email deliverability: Both are excellent. Neither platform will cause deliverability issues for normal use.
Portability: Both allow you to export your subscriber list as CSV at any time. You're never locked in. This is critical — always verify this before committing to any platform.
Our recommendation
Start with Substack. It's simpler, free, and the recommendation engine gives you a growth advantage that's hard to replicate. When you hit 500-1,000 subscribers and find yourself wanting A/B testing, better analytics, or referral programs, migrate to Beehiiv. The migration is straightforward — export your subscriber CSV from Substack, import into Beehiiv, and redirect your old Substack URL.
What About Other Platforms?
ConvertKit (now Kit): Excellent for automation and selling digital products. Overkill for a simple newsletter, but worth considering if you plan to sell courses or templates alongside your newsletter.
Ghost: Self-hosted option with full control. Best for technical writers who want complete ownership and don't mind managing the infrastructure. Higher setup effort but zero platform risk.
Mailchimp: Not recommended for newsletters. It's designed for marketing campaigns, not editorial content. The editor, pricing, and analytics aren't optimized for newsletter writing.
