When should you choose Sequenzy?

1. You Need Email Marketing, Not Notification Infrastructure

Knock is notification infrastructure - it delivers messages across channels but doesn't have marketing features. If you need email campaigns, subscriber segments, and AI-generated sequences, Sequenzy is purpose-built for that. Knock would require a separate marketing tool.

2. You Want Simple, Affordable Pricing

Knock's Starter plan is $250/month for 50k messages. At 10k contacts, Sequenzy is $49/month. If you primarily need email (not in-app notifications or push), you're paying 5x more with Knock for capabilities you don't use. Check our transparent pricing to compare.

3. You Want Native Stripe Integration

Sequenzy connects directly to Stripe via our native integration and syncs customer data, MRR, subscription status, and churn signals automatically. Knock requires you to manually send events via their API. If your billing is in Stripe, we make it effortless.

4. You Want AI-Generated Email Content

Describe what you want ("a 5-email trial-to-paid sequence for a project management SaaS") and our AI generates the emails. Knock has no content creation features - it's infrastructure for delivering messages, not creating them.

When should you stick with Knock?

1. You Need In-App Notifications

Knock's killer feature is pre-built in-app notification components. A notification bell with a feed of updates - the kind you see in Slack or Linear. We don't have this. If you need in-app notification UI, Knock saves weeks of development time.

2. You Need Multi-Channel Orchestration

Knock handles email, push notifications, SMS, in-app messages, and chat platforms (Slack, Discord) from one unified system. You can set up fallback logic (if push fails, send email). We only do email. For true multi-channel notifications, Knock is the right choice.

3. You Have Engineering Resources

Knock is built for engineering teams who want to abstract notification complexity. It's infrastructure, not a marketing tool. If you have developers who want to build a sophisticated notification system, Knock is powerful. Read our guide on transactional email architecture to understand the difference.

4. You Need User Notification Preferences

Knock has a sophisticated preference center where users can choose which channels they want notifications on. We have basic unsubscribe handling, not channel preferences. If users need to control their notification experience across channels, Knock wins.

5. You Need Workflow Sophistication

Knock's workflow engine handles complex scenarios - batch notifications, channel fallbacks, conditional routing based on user preferences. Our email sequences are simpler. If you need infrastructure-level notification orchestration, Knock is more powerful.

Honest Limitations of Sequenzy

  • Email only: No in-app notifications, push, SMS, or chat integrations.
  • No notification UI components: We don't have pre-built notification bells/feeds for your app.
  • Simpler workflows: Our automation is great for email marketing but less sophisticated than Knock's notification orchestration.
  • No channel preference center: Basic unsubscribe handling only.
  • Smaller free tier: 100 subscribers vs Knock's 10k messages.

Honest Limitations of Knock

  • Not a marketing platform: No email campaigns, subscriber segments, or marketing automation.
  • Expensive for small teams: $250/mo minimum after the free tier.
  • No content creation: Delivers messages but doesn't help you write them. No AI features.
  • Requires developer integration: Not a no-code marketing tool. You need engineering resources.
  • No Stripe integration: You have to build your own event tracking for billing data.
  • Different purpose: Knock is infrastructure. If you want a marketing platform, you need something else.

Yes, 10,000 messages per month on the free Developer plan. That's more generous than Sequenzy's 100 subscribers for testing. But once you scale past free, Knock's Starter plan is $250/mo.
