Pros & Cons
10 pros·6 cons across both
S
S
Substack
+5-3
Pros
- 90% revenue share for creators on paid subscriptions (industry-leading)
- Free plan supports unlimited subscribers with no feature restrictions
- One-click setup; no technical knowledge required to launch
- Built-in payment processing via Stripe; automatic subscriber paywall
- Growing network effect with 500K+ active publications and 50M+ monthly readers
Cons
- No advanced email automation or drip campaigns beyond basic welcome series
- Limited segmentation; cannot target subscribers by behavior or engagement level
- No e-commerce integrations; cannot sync with Shopify or WooCommerce
Mailchimp
+5-3
Pros
- 300+ pre-built automation workflows for complex customer journeys
- Advanced segmentation using 50+ behavioral, demographic, and purchase data points
- Native integrations with Shopify, WooCommerce, BigCommerce, and 300+ apps
- A/B testing for subject lines, content, send times with statistical significance reporting
- Free plan includes up to 500 contacts with full feature access (automation, segmentation, reporting)
Cons
- Steeper learning curve; automation and segmentation require 2-4 hours to master
- Pricing scales aggressively; $20-$350/month for 1K-100K contacts vs Substack's flat rates
- No revenue sharing; all subscription revenue goes to the business, not creators
Frequently Asked Questions
5 questions
Substack is optimized for creator newsletters, not business marketing. It lacks automation, segmentation, and e-commerce integration. While you can use it to email a list, Mailchimp is significantly better for business campaigns with triggered workflows, behavioral targeting, and Shopify sync.
