Overview

MailerLite and Substack represent two fundamentally different newsletter strategies. Substack is a free publishing network where discovery and simplicity are the draws. MailerLite is a paid email marketing platform where control and features are the value proposition. The choice comes down to what matters more: built-in audience growth or full ownership and flexibility.

The Cost Equation

Substack costs nothing upfront. You publish for free and only pay if you enable paid subscriptions (10% of revenue plus Stripe fees). MailerLite costs $73/month at 10,000 subscribers regardless of revenue.

The breakeven point is approximately $730/month in paid subscription revenue. Below that, Substack is cheaper. Above that, MailerLite saves money. At $3,000/month in newsletter revenue, you'd pay Substack $300 versus MailerLite's flat $73.

Discovery vs Control

Substack's greatest strength is its network. Recommendations from other writers, the Notes social feed, leaderboards, and the Substack app all drive organic subscriber growth. Many writers attribute thousands of subscribers to these discovery features.

MailerLite offers no discovery mechanism. Growth comes from your own efforts: landing pages, pop-ups, social media, and content marketing. You have full control but no built-in audience.

Design and Branding

MailerLite gives you complete design freedom with a visual drag-and-drop editor, custom templates, and full branding control. Your emails look exactly how you want.

Substack enforces a consistent, text-focused design. Customization is minimal. Your newsletter will always look like a Substack newsletter. For some writers, this simplicity is a feature. For brands wanting unique identity, it's a limitation.

Marketing Features

MailerLite is a proper email marketing platform. Automation workflows, A/B testing, segmentation, landing pages, and e-commerce integrations give you tools to grow and optimize. Substack has none of these. You write, you publish, it sends.

For SaaS Companies

Neither platform is ideal for SaaS. MailerLite lacks Stripe integration for subscription-aware messaging. Substack is purely a publishing platform. For SaaS companies wanting newsletter capabilities alongside product email and Stripe integration, consider Sequenzy at $49/month.
