Newsletter Platform Comparison: Substack vs Beehiiv vs ConvertKit

Social media algorithms control who sees your content. Email newsletters bypass algorithms entirely — every subscriber gets every issue in their inbox. For creators, building an email list is the most valuable audience-building investment you can make.

Why Newsletters Matter for Creators

Platforms can change algorithms, demonetize content, or shut down entirely. Your email list belongs to you. You can export it and move to any platform. A newsletter with 10,000 engaged subscribers is more valuable than 100,000 social media followers because you have direct, reliable access to every subscriber.

Newsletters also monetize well through paid subscriptions, sponsorships, and affiliate marketing. Top newsletter creators earn six to seven figures annually from audiences a fraction of the size needed on YouTube or Instagram.

Substack: The Creator-First Platform

Substack is free for free newsletters. For paid newsletters, Substack takes 10% of subscription revenue plus payment processing fees. It provides a built-in discovery network (Substack Notes, recommendations) that helps grow your audience.

Substack's strength is simplicity — write, hit publish, and it handles delivery, payments, and archive. The built-in readership makes it easier to grow from zero than platforms without discovery features. The 10% revenue cut is the tradeoff for this simplicity and discoverability.

Beehiiv: The Growth-Focused Platform

Beehiiv is free for up to 2,500 subscribers with full features including custom domains, referral programs, and ad monetization. Paid plans start at $49/month. Beehiiv takes zero percent of subscription revenue.

Beehiiv's referral program (readers earn rewards for referring new subscribers) is its killer feature. Its analytics are more detailed than Substack's, and the ad marketplace connects you with sponsors automatically once your list reaches sufficient size.

ConvertKit (now Kit): The Professional Choice

Kit is free for up to 10,000 subscribers (limited features) with paid plans starting at $29/month. It is designed for professional creators who need advanced automation, segmentation, and landing pages.

Kit excels at automation — send different emails based on subscriber behavior, create complex welcome sequences, and segment your audience by interests. For creators selling digital products, courses, or services, Kit's automation and commerce features are unmatched.

Other Options

Mailchimp offers a free tier for up to 500 subscribers but has become less creator-friendly over time. Buttondown is a minimalist, developer-friendly option. Ghost is an open-source platform you can self-host for complete control. Flodesk offers flat-rate pricing ($38/month unlimited subscribers) with beautiful templates.

Which One to Choose

Just starting, want simplicity: Substack. Its discovery network helps you find initial readers, and the free tier has no limitations.

Growing a list, want monetization tools: Beehiiv. The referral program, ad marketplace, and zero revenue share make it the best growth platform.

Selling products or courses: Kit. Its automation and commerce features are designed for creators with diversified revenue.

Getting Your First 1,000 Subscribers

Promote your newsletter in every video, podcast, social media bio, and community you participate in. Offer a compelling reason to subscribe — exclusive content, early access, or a free resource. Cross-promote with other creators in your niche. Consistency is key — publish on a regular schedule and deliver genuine value in every issue.
