Mailchimp and Substack are both popular email marketing platforms, but they serve different primary audiences. Mailchimp is a comprehensive marketing automation tool built for small businesses and marketing teams, while Substack is purpose-built for writers and creators who want to monetize newsletters directly. Understanding their key differences will help you choose the right platform for your specific needs.

It depends on your use case. Mailchimp is better for businesses needing marketing automation, landing pages, and advanced segmentation. Substack is better for writers and creators focused on direct subscriber monetization. Mailchimp offers more comprehensive features overall, while Substack excels at newsletter monetization and audience building.
Substack has a free tier with no subscriber limits and only takes a 10% cut of paid subscriptions you earn. Mailchimp is free up to 500 subscribers but requires paid plans ($13+/month) for larger lists. For monetized newsletters, Substack can be more cost-effective; for business automation, Mailchimp's pricing is competitive.
Yes, you can export your subscriber list from Substack and import it into Mailchimp. However, you'll lose Substack-specific features like paid subscriptions and podcast hosting. The switch is straightforward for basic email lists but may require rebuilding automations and segments in Mailchimp.
