Substack vs Mailchimp: The Side-by-Side Breakdown
Substack and Mailchimp sit in the Marketing bucket but move at different cadences. Substack is shaped by hosted newsletter and publication platform with built-in payments, recommendations, and an audience network for writers; standouts include built-in stripe payments and tax handling, notes feed and cross-publication recommendations, podcast hosting and audio newsletters. Mailchimp is shaped by all-in-one marketing platform built around email campaigns, automations, and audience insights for growing brands; a/b testing and reporting dashboards, drag-and-drop email and template builder, behavior-triggered automations and customer journeys carry the pitch. Substack stumbles on limited design and customization control. Mailchimp stumbles on advanced automations feel limited compared to dedicated platforms.
