Pricing Comparison

ConvertKit Pricing Structure (as of April 12, 2026):

ConvertKit offers three distinct tiers with subscriber-based pricing:

• Newsletter (Free): Up to 10,000 subscribers with basic features including unlimited landing pages, forms, email broadcasts, and the ability to sell digital products
• Creator: Starting at $33/month ($32.50 annually) for up to 1,000 subscribers, adding unlimited visual automations, A/B testing, and premium support
• Pro: $66/month ($65.83 annually) for up to 1,000 subscribers, including unlimited users, advanced analytics, deliverability reporting, and collaborative editing

ConvertKit’s pricing scales with subscriber count, making it cost-effective for growing lists but potentially expensive for large audiences.

Substack Pricing: While specific Substack pricing data wasn’t available in our dataset, the platform typically operates on a revenue-sharing model for free accounts and offers Pro plans for creators wanting more control over monetization.

The key difference: ConvertKit charges based on subscriber count regardless of revenue, while Substack’s free tier takes a percentage of paid subscriptions but allows unlimited free subscribers.

Feature Deep Dive

Email Automation & Sequences

ConvertKit excels with visual automation builders. Even the free Newsletter plan includes basic visual automations, while Creator and Pro plans offer unlimited sequences. You can create complex subscriber journeys based on tags, behaviors, and engagement levels.

Substack keeps automation simple, focusing on basic welcome sequences and publication schedules. This simplicity works well for straightforward newsletter publishing but limits advanced nurturing campaigns.

Audience Segmentation & Tagging

ConvertKit provides sophisticated tagging and segmentation across all plans, allowing precise audience targeting. The Pro plan adds subscriber engagement scoring to identify your most active readers.

Substack offers basic subscriber management but lacks the granular segmentation tools that ConvertKit provides. This makes targeted campaigns more challenging.

Monetization Options

ConvertKit enables selling digital products, subscriptions, and courses directly through the platform. Even the free tier includes e-commerce capabilities, making it attractive for creators with diverse revenue streams.

Substack focuses primarily on paid newsletter subscriptions with its built-in payment processing, though it’s expanding into other creator economy features.

Content Discovery

ConvertKit requires you to build your own audience through external channels and integrations.

Substack offers a significant advantage with its reader network and recommendation system, helping newsletters gain organic discovery within the platform.

Who Should Choose ConvertKit

Established Course Creators: If you’re selling online courses, digital products, or multiple revenue streams, ConvertKit’s e-commerce integration and advanced automation make it the clear choice. The visual automation builder helps nurture leads through complex sales funnels.

Marketing-Savvy Entrepreneurs: Creators who want granular control over subscriber segmentation, A/B testing, and detailed analytics will appreciate ConvertKit’s Pro plan features like engagement scoring and deliverability reporting.

Growing Creator Businesses: The generous free tier (up to 10,000 subscribers) makes ConvertKit attractive for creators scaling their audience without immediate revenue pressure.

Teams and Agencies: The Pro plan’s unlimited users and collaborative editing features serve agencies or creator teams better than Substack’s individual-focused approach.

Who Should Choose Substack

Newsletter-First Writers: Authors and journalists who primarily want to publish regular newsletters with minimal technical complexity will find Substack’s streamlined interface ideal.

New Content Creators: Writers starting from zero benefit from Substack’s built-in discovery mechanisms and reader network, reducing the cold-start problem of audience building.

Subscription-Focused Creators: If paid newsletter subscriptions are your primary revenue model, Substack’s integrated payment system and reader expectations around paid content create natural monetization opportunities.

Simplicity Seekers: Creators who prefer focusing on writing over marketing automation will appreciate Substack’s straightforward publishing workflow.

Migration Considerations

Moving from Substack to ConvertKit

Data Export: Substack allows subscriber list exports, but you’ll lose engagement history and subscriber preferences. Plan to re-segment your audience using ConvertKit’s tagging system.

Content Migration: Newsletter archives don’t transfer directly. Consider whether to maintain Substack for historical content or manually recreate key pieces.

Learning Curve: ConvertKit’s advanced features require more setup time. Budget 2-4 weeks to properly configure automations and segments.

Moving from ConvertKit to Substack

Feature Loss: You’ll lose advanced automation, detailed segmentation, and e-commerce capabilities. Ensure these aren’t critical to your current strategy.

Subscriber Experience: The transition from marketing-style emails to Substack’s newsletter format may confuse existing subscribers. Clear communication is essential.

Revenue Model Shift: If you monetize beyond subscriptions, you’ll need alternative solutions for course sales, digital products, or affiliate marketing.

FAQ

Which platform is better for beginners?

Substack is significantly more beginner-friendly due to its simplified interface and built-in audience discovery. New creators can start publishing immediately without learning complex automation or segmentation concepts. ConvertKit requires more initial setup but offers greater long-term flexibility.

Can I use both platforms simultaneously?

Yes, many creators use Substack for newsletter publishing while leveraging ConvertKit for advanced email marketing and product sales. However, this approach requires careful subscriber management to avoid confusion and comply with email regulations.

How do the free tiers compare?

ConvertKit’s free tier is more generous, supporting up to 10,000 subscribers with core features including landing pages and basic automation. Substack’s free tier has no subscriber limits but takes 10% of paid subscription revenue, making it better for creators prioritizing audience growth over immediate monetization.

Which platform has better deliverability?

ConvertKit provides detailed deliverability reporting in its Pro plan and focuses heavily on email deliverability optimization. Substack’s deliverability is generally good due to its newsletter-focused reputation with email providers, but it offers less transparency about delivery metrics.

What about customer support?

ConvertKit offers 24/7 email and chat support for Creator and Pro plans, with priority support for Pro users. Substack’s support is more limited, typically responding via email with longer response times, reflecting its focus on simplicity over comprehensive service.

Can I sell products other than subscriptions?

ConvertKit excels at selling diverse digital products, courses, and physical goods through its integrated commerce features. Substack is primarily designed for subscription newsletters, though it’s expanding into other creator economy features like one-time payments and merchandise.

Which platform scales better for large audiences?

This depends on your business model. ConvertKit’s subscriber-based pricing can become expensive for large lists (100K+ subscribers), but its segmentation and automation features handle large audiences well. Substack’s revenue-sharing model may be more cost-effective for large free audiences with smaller paid subscriber percentages.
