The three platforms that dominate the online course market each target a different stage of the creator journey. Understanding which stage you're at — not which platform has the most features — is how you avoid the most expensive mistake in this space: buying a $149/month all-in-one tool before you've made your first dollar from courses.
| Platform | Starting price | Transaction fees | Email marketing | Best for |
|---|---|---|---|---|
| Thinkific | Free (1 course) / $36/month | None | Basic (paid email add-on) | New creators, clean UX |
| Teachable | Free / $39/month | 5% on free; 0% on paid | Basic (no automation) | Creators who want a proven brand |
| Kajabi | $149/month | None | Full email automation included | Established creators ($3K+/month) |
Thinkific is the cleanest, most creator-friendly course platform for someone building their first course. The free plan lets you publish one course with unlimited students and zero transaction fees — genuinely free, not "free with a catch." The Basic plan at $36/month removes the one-course limit and adds drip scheduling (releasing course content on a schedule), which is essential for structured courses where you don't want students to binge past week 3 before completing week 1.
What Thinkific does well:
What Thinkific doesn't do well:
Teachable is the most recognized name in online courses — many buyers trust a course platform they recognize, which has a small but real effect on conversion rates. The Teachable Basic plan at $39/month is comparable to Thinkific's starter offering, with two meaningful differences: Teachable has a larger creator community and ecosystem of consultants, integrations, and resources, but charges a 5% transaction fee on the free plan that Thinkific doesn't.
What Teachable does well:
The honest case against Teachable: The 5% transaction fee on the free plan is significant. At $197/course with 50 students in a launch: $197 × 50 × 5% = $492.50 in fees. That's more than a month of Teachable Basic. Upgrade to Basic immediately if you're on the free plan and have any sales volume. The $39/month Basic plan removes all transaction fees, which makes the economics identical to Thinkific in terms of platform cost.
Kajabi is the course industry's premium all-in-one platform. $149/month gets you course hosting, full email marketing automation, landing pages, pipelines (sales funnels), communities, podcasting, and a website builder — everything a course creator business needs, in one tool, without stitching together 4-5 subscriptions.
The pitch is compelling. The math only works at a specific revenue threshold.
What Kajabi includes that Teachable and Thinkific don't:
The Kajabi math: The subscription stack Kajabi replaces at scale: Thinkific Basic ($36) + ConvertKit Starter ($25) + landing page tool ($29) + community tool ($49) = $139/month. Kajabi at $149 saves $0 per month over this stack while providing a somewhat less specialized version of each tool. The real value argument for Kajabi is integration simplicity (one login, no Zapier connections) and the time cost of maintaining multiple tools — not raw feature comparison at list price.
When Kajabi is genuinely the right call:
When Kajabi is the wrong call:
Both Thinkific and Teachable assume you'll use an external email marketing tool. Kajabi has email marketing built in. Here's the thing: ConvertKit is better at email marketing than Kajabi's built-in tools — more tag-based segmentation, better deliverability, cleaner automation builder, and integrations with more tools.
If you start on Thinkific + ConvertKit and later move to Kajabi, you'll likely keep ConvertKit for email anyway. The "one fewer tool" argument for Kajabi's email is weakened by the fact that many established Kajabi users still use ConvertKit alongside it for their highest-stakes email work.
Disclosure: I earn a 30% recurring commission if you sign up for ConvertKit via my link. The honest recommendation stands independent of that — ConvertKit's automation and segmentation capabilities are genuinely superior to any course platform's built-in email tools.

Whatever platform you choose, your course materials need to look polished. Canva Pro is the single most impactful tool for course visual quality — workbooks, slide decks, resource PDFs, social proof graphics, and promotional materials all come out at professional quality in a fraction of the time it takes in PowerPoint or Keynote.
The Canva → Thinkific workflow: design your course workbook in Canva → export as PDF → upload as a downloadable resource in Thinkific → students download as part of their enrollment. For a $197 course, a professional workbook increases perceived value and completion rates meaningfully. For $13/month, it's the highest-ROI tool in the course creator stack after the platform itself.

You're building your first course and haven't launched yet: Start on Thinkific free. Validate that you can sell the course before paying a monthly fee. Once you've made your first 5-10 sales, upgrade to Thinkific Basic ($36/month) and add ConvertKit for email.
You have a small audience (email list under 5,000) and want the most established brand: Teachable Basic at $39/month. Slightly better coaching features, recognizable name, affiliate management built in.
You're consistently earning $3,000+/month and managing 4+ separate tools (email, landing pages, course platform, community): Evaluate Kajabi. The consolidation benefit becomes real at this revenue level and complexity.
You're considering Kajabi because it "seems like what successful course creators use": That's the right signal that it's the wrong reason. Thinkific + ConvertKit + Canva produces course businesses that look just as professional and keep more revenue in your pocket until you genuinely need the consolidation.
Platform choice doesn't determine whether your course sells. Your audience size, the quality of your content, your email list, and your ability to talk about the problem you solve determine whether your course sells. The platform is plumbing. Start with the cheapest plumbing that doesn't leak — which is Thinkific for most people — and upgrade when the plumbing starts to slow you down, not before.
