Sequenzy vs Substack: Revenue Attribution vs Writer Platform

Overview

Sequenzy and Substack serve fundamentally different needs. Substack is a platform for writers to build paid newsletter businesses with zero upfront cost. Sequenzy is a comprehensive email broadcast service for businesses wanting revenue attribution.

Key Differences

Pricing Model

Substack is free until you charge subscribers, then takes 10% of your paid subscription revenue. For writers starting out, this removes upfront costs entirely.

Sequenzy charges a flat monthly fee regardless of revenue. As your revenue grows, the percentage you effectively pay to Sequenzy decreases dramatically.

Platform vs Tool

Substack is a platform. Readers follow you on Substack, discover content through the Substack app, and your newsletter lives within their ecosystem. This provides discovery benefits but creates platform dependency.

Sequenzy is a tool you own. Your subscriber list is yours, your branding is yours, and you can migrate anytime. No platform lock-in, but also no built-in discovery.

Who Should Choose What

Choose Sequenzy if:

• You run a SaaS or product business
• You want full control over branding and data
• You need sophisticated automation and sequences
• Your revenue will exceed $190/mo (10% of $1,900)
• You want to avoid platform dependency
• You need subscriber segmentation by billing data
• You want to track email-driven revenue precisely
• You use Stripe, Polar, or Creem for billing

Choose Substack if:

• You are a writer starting a paid newsletter
• You want zero upfront costs
• You value the Substack network for discovery
• You prefer simplicity over customization
• Your revenue is modest or just starting
• You don't need advanced automation
• You're okay with platform lock-in

The Bottom Line

For businesses and SaaS companies, Sequenzy is the clear choice. The 10% revenue share on Substack becomes expensive quickly, and the limited automation cannot support sophisticated email strategies.

For writers building a paid newsletter from scratch, Substack's zero-cost start and built-in discovery make it compelling. Just understand that as you grow, you will eventually pay more than a flat-fee service like Sequenzy.
