- E-commerce founders running their own marketing without a dedicated team
- Brands graduating from Mailchimp's e-commerce features

- Creators running pure newsletters (use Kit or beehiiv)
- Large e-commerce operations needing custom data modeling (Klaviyo or Customer.io)
When Substack wins
- New writers with no list yet who want platform-driven discovery
- Writers who would rather give 10% of revenue than pay a flat $20-100/month with no readers

- Operators who want full control over deliverability, subscriber data, and migration optionality
