The biggest difference: fixed pricing vs revenue share

MailerLite charges according to your plan and subscriber tier. Paid newsletter features are available on its paid plans, and your platform cost does not automatically increase as a percentage of your subscription revenue.

Substack uses a different model. Publishing can be free, but when you enable paid subscriptions, its standard fee is 10% of paid transactions, plus applicable payment processing charges.

Example: $3,000/month in paid subscription revenue

At the standard Substack rate, the platform fee alone would be approximately $300 per month, before applicable Stripe fees.

When MailerLite makes more sense

MailerLite can make more sense if you want a newsletter to be part of a broader email marketing system. It gives you automations, landing pages, forms and more control over how subscribers move through your audience.

When Substack makes more sense

Substack can be a better fit if simplicity and publishing speed matter more than advanced email marketing tools. Its built-in network can also help writers who want to participate in the Substack ecosystem.
