What Each Platform Costs at Different Revenue Levels
| Monthly subscription revenue | Sequenzy | Substack |
|---|---|---|
| $0 (free newsletter only) | Free up to 2,500 emails/mo | Free |
| $1,000/mo | $19-99/mo flat, no revenue share | ~$130-160/mo (10% cut + processing fees) |
| $10,000/mo | $19-99/mo flat, no revenue share | ~$1,300-1,600/mo (10% cut + processing fees) |
The gap widens as revenue grows, since Substack's cost is a percentage of revenue while Sequenzy's is a flat platform fee based on email volume, not income.
Best Fit by Use Case
Best for a single writer building an audience through discovery
Substack is the better fit when you're starting from zero audience and want to lean on its recommendation network and reader discovery to find your first subscribers.
Best for a business or product with an existing audience
Sequenzy is the better fit once you already have a way to reach your audience (a product, a website, existing channels) and don't need Substack's discovery mechanism, since you keep 100% of subscription revenue instead of paying a 10% cut.
Best for teams outgrowing a single-newsletter format
Sequenzy is the better fit once you need segmentation, multi-step automation, forms, or a marketing funnel beyond what a single publishing-first tool supports.

Evaluating Substack vs Sequenzy for Your Project
- Decide how you'll find your first readers. If you have no existing audience, Substack's discovery network has real value. If you're bringing an existing audience, that value is smaller.
- Estimate your subscription revenue at scale. Model Substack's 10% cut against your realistic revenue in a year, not just your first month, since the cost compounds as you grow.
- Check whether you need automation beyond a newsletter send. If you want behavior-triggered sequences, segmentation, or forms, Substack doesn't offer these at all.
- Consider the switching cost later. Migrating a list is straightforward; migrating away from Substack's built-in paid subscription and discovery network is not.
When should you choose Sequenzy?
1. You Already Have an Audience or Distribution Channel
If you're not relying on Substack's discovery network to find readers, there's no offsetting benefit to giving up 10% of subscription revenue.
2. You Want Marketing Automation, Not Just a Newsletter Send
Sequenzy's automation builder and smart segments support behavior-triggered sequences Substack has no equivalent for.
3. You Want to Keep 100% of Subscription Revenue
Sequenzy's flat fee model means your subscription revenue isn't taxed as it grows, unlike Substack's indefinite 10% cut.
4. You Need Transactional Email Alongside Marketing
Sequenzy handles both from one platform. Substack has no transactional email capability at all.
When should you choose Substack?
1. You're Starting From Zero Audience
Substack's recommendation network and reader discovery genuinely help new writers find their first subscribers in a way no email marketing platform replicates.
2. You Want Zero-Setup Paid Subscriptions
Substack's built-in billing and paywall require no integration work, a real advantage over connecting and configuring a payment provider yourself.
3. Your Workflow Is Fundamentally "Write and Publish"
If your only job is writing and publishing a regular newsletter, Substack's simplicity is a feature, not a limitation.
Who Should Use Each Platform
Choose Sequenzy if you are:
- A SaaS or AI company needing marketing automation and lifecycle email

Honest Limitations of Substack
- No marketing automation, sequences, or behavioral segmentation
