If you're selling online courses, your email list is where the money is. Students find you through social media or search, but they buy because you've nurtured them through a launch sequence, case study emails, or a well-timed objection-handling campaign. The problem? Most email tools weren't built for course creators—they're either too expensive for the way you actually use them (big list, infrequent sends), lack the automations you need for launch sequences, or don't integrate cleanly with your course platform.

This guide walks through the tools that actually make sense for course creators in 2025. I'll show you which ones integrate natively with Teachable, Thinkific, and other course platforms, how pricing scales when your list grows, and—most importantly—when you should skip the expensive option and use a free or cheaper tool instead.

By the end, you'll know exactly which email platform fits your course business model, budget, and technical comfort level.

Quick Comparison Table

Kit (Formerly ConvertKit): The Industry Standard—But Newly Expensive

What it's genuinely good at: Kit is purpose-built for creators who sell digital products. Its tag-based subscriber system makes launch sequences straightforward: someone downloads your lead magnet, gets tagged "Lead Magnet A," enters a 5-email nurture sequence, and if they buy, gets tagged "Customer – Course A" and automatically removed from future sales emails for that course. This is exactly how course launches work in practice.

The native integrations with Teachable, Thinkific, and Podia are the real advantage. When a student purchases your course, Kit automatically fires the student onboarding sequence—no Zapier subscription, no webhook debugging, no maintenance burden. For creators running multiple courses, this integration alone saves hours of technical headache.

Kit Commerce (their built-in checkout) is increasingly competitive. On the free plan, you pay 3.5% + $0.30 per transaction; on paid plans, transaction fees drop to 0%. For a $500 course sale, that's $17.80 in fees on the free plan versus $0 on the Creator plan. After two sales, the Creator plan pays for itself.

Who it fits: Course creators who launch 2-4 times per year, maintain a list between 1,000-10,000 subscribers, and use Teachable, Thinkific, or Podia for course hosting. If you're running conditional automation (if clicked but didn't buy, send objection email; if bought, send student onboarding), Kit's visual automation builder is hard to beat.

Real downsides: Kit raised prices dramatically in September 2025—the Creator plan jumped from $15/month to $33/month for 1,000 subscribers, a 120% increase. At 10,000 subscribers, you're paying $149/month ($1,788/year). Many long-time users feel priced out, especially if they only launch once or twice per year.

The free plan looks generous (10,000 subscribers) but limits you to 1 active automation. That's fine for testing, but you can't run a real course business with one automation—you need separate sequences for lead nurture, launch, post-purchase onboarding, and cart abandonment.

Kit has no built-in course hosting. You're still paying Teachable or Thinkific separately for video hosting and course delivery. Kit Commerce only handles payments and email delivery.

Email design is deliberately minimal. If you're used to Flodesk's visual templates or Mailchimp's drag-and-drop builder, Kit's text-heavy aesthetic feels spartan. Advanced reporting (revenue attribution by email) requires third-party integrations.

Pricing (as of March 2026): Free (up to 10,000 subscribers, 1 automation), Creator from $29-33/month (varies by annual vs monthly billing), Creator Pro from $59/month. Pricing scales with contact count: expect $79/mo at 3,000 contacts, $149/mo at 10,000.

MailerLite: The Budget Alternative With Trade-Offs

What it's genuinely good at: MailerLite offers the most generous free plan among serious competitors—1,000 subscribers with unlimited email sends and basic automation. The interface is clean and beginner-friendly, and pricing stays reasonable as you scale: $9/month at 500 contacts, $19/month at 2,500 contacts.

The drag-and-drop email builder is more visual than Kit's, which appeals to creators coming from social media backgrounds. You can build decent-looking newsletters without HTML knowledge.

Who it fits: Brand-new course creators testing their first lead magnet and mini-course. If you're pre-launch or have fewer than 1,000 subscribers, MailerLite's free plan gives you room to experiment without monthly bills.

Real downsides: Course platform integrations are weak. MailerLite doesn't have native connections to Teachable, Thinkific, or most course platforms—you'll need Zapier to trigger post-purchase sequences, which adds $20-30/month and maintenance overhead.

Automation capabilities are shallower than Kit. Conditional logic exists but is less intuitive to build. Tag management works but feels like an afterthought compared to Kit's tag-first architecture.

Segmentation is coarser. You can segment by opened/clicked/purchased, but granular behavioral triggers (clicked link X but not link Y) require workarounds.

Pricing: Free (up to 1,000 subscribers), $9/month (500 contacts), $19/month (2,500 contacts), scaling to $69/month at 10,000 contacts.

Honest take: If you're pre-revenue and testing your first course idea, MailerLite's free plan is a smart starting point. Once you're making sales and need reliable course platform integration, the Zapier tax and automation limitations will push you toward Kit or an all-in-one.

systeme.io: All-in-One for Solo Course Creators

What it's genuinely good at: Systeme.io bundles email marketing, course hosting, sales funnels, and checkout into one platform. You're not paying Teachable + Kit + Zapier separately—everything runs on one bill. The free plan includes 2,000 contacts and unlimited email sends, which is legitimately generous.

Course hosting is straightforward: upload videos, set up modules, drip content by schedule. The checkout builder handles one-time payments, payment plans, and order bumps without third-party tools.

Who it fits: Solo course creators who want simplicity over best-in-class features. If you're launching your first course and don't want to manage integrations between three platforms, Systeme.io removes that complexity.

Real downsides: Email features are functional but basic. Automation exists but lacks the depth of Kit or ActiveCampaign. You can build a launch sequence, but complex conditional branching gets clunky fast.

The email builder is plain. If email design matters to your brand, you'll find the templates limiting.

Course hosting works but isn't as polished as Teachable or Thinkific. Student experience is fine for straightforward video courses but lacks advanced features like certificates, quizzes, or community forums.

You're locked into one ecosystem. If you outgrow Systeme.io's email capabilities and want to switch to Kit, you'll need to migrate your course hosting too—everything's bundled.

Pricing: Free (2,000 contacts, 1 course), Startup $27/month (5,000 contacts, 5 courses), Webinar $47/month (10,000 contacts, 10 courses), Unlimited $97/month (unlimited everything).

Honest take: If you're a solo creator launching your first course and want one tool that does everything "good enough," Systeme.io is hard to beat at $27/month. Once you're doing $5K+/month in course revenue, you'll likely outgrow the email features and want to move to a standalone ESP + better course platform.

ActiveCampaign: For Advanced Marketers Who Need CRM-Level Segmentation

What it's genuinely good at: ActiveCampaign offers the deepest automation and segmentation of any tool here. You can build multi-path launch sequences with conditional logic based on dozens of behavioral triggers: opened email A but not B, clicked link X, visited sales page Y times, etc.

The CRM features let you track individual subscriber journeys and manually intervene when someone's stuck in a sequence. For creators running high-touch cohort-based courses, this visibility is valuable.

Who it fits: Experienced marketers running complex evergreen funnels or multi-course product lines. If you're segmenting by lead source, engagement level, and purchase history across 3+ products, ActiveCampaign's power justifies the learning curve.

Real downsides: Steep learning curve. ActiveCampaign is built for marketers who understand CRM concepts. If you're new to email marketing, the interface feels overwhelming.

Course platform integrations require Zapier for most platforms. You're not getting the plug-and-play experience Kit offers.

Pricing scales quickly. You start at $15/month for 500 contacts, but at 2,500 contacts you're paying $93/month—more than Kit at the same list size.

Pricing: $15/month (500 contacts), $49/month (1,000 contacts), $93/month (2,500 contacts), scaling steeply with contact count.

Honest take: Overkill for most course creators. Unless you're running sophisticated multi-product funnels and need CRM-level tracking, Kit or MailerLite will serve you better at lower cost.

Kartra: All-in-One for Established Course Businesses

What it's genuinely good at: Kartra is a complete online business platform: email marketing, course hosting, membership sites, checkout, affiliate management, and helpdesk in one tool. For creators running full-scale course businesses with multiple products and affiliates, consolidating everything eliminates integration headaches.

The membership site features are robust—you can build drip content schedules, community forums, and tiered access levels that most standalone course platforms don't offer.

Who it fits: Established course creators doing $10K+/month in revenue who want enterprise features without enterprise complexity. If you're managing affiliates, running a membership site, and need integrated helpdesk support, Kartra's consolidation makes sense.

Real downsides: Expensive for beginners. Starter plan is ~$59/month, and you'll likely need the $119/month Growth plan for serious course businesses.

Email features are functional but not best-in-class. Automation works but feels less intuitive than Kit. Email deliverability is solid but not industry-leading.

Steep learning curve. Kartra can do everything, which means there's a lot to learn. Expect a month of setup before you're running smoothly.

Pricing: ~$59/month (Starter), ~$119/month (Growth), ~$229/month (Professional). Exact pricing varies by annual vs monthly billing.

Honest take: Don't start with Kartra. If you're pre-launch or doing under $5K/month in course revenue, the cost and complexity aren't justified. Once you're established and tired of managing Teachable + Kit + affiliate software + helpdesk separately, Kartra's consolidation becomes appealing.

Flodesk: Beautiful Emails, But a Niche Fit for Course Creators

What it's genuinely good at: Flodesk builds the most visually stunning emails of any tool here. If your brand is design-forward and you want emails that look like Instagram posts, Flodesk delivers.

Flat-rate pricing ($38/month unlimited contacts) is appealing if you have a large list. At 10,000+ subscribers, Flodesk is cheaper than Kit or ActiveCampaign.

Who it fits: Visual-first creators with smaller lists (under 5,000) who prioritize brand aesthetics and send broadcast emails more than automated sequences.

Real downsides: No native course platform integrations. You'll need Zapier for everything, which adds cost and complexity.

Automation is basic. You can build simple sequences, but conditional logic and behavioral triggers are limited compared to Kit or ActiveCampaign.

Tag management is clunky. Flodesk is built around segments, not tags, which makes launch sequences harder to manage.

Pricing: $38/month flat rate (unlimited contacts).

Honest take: Flodesk is built for lifestyle creators who send beautiful newsletters, not for course creators running launch sequences and student onboarding. Unless email aesthetics are central to your brand and you're willing to pay for Zapier, choose a tool built for course sales.

GetResponse: Solid Mid-Tier Option With Webinar Features

What it's genuinely good at: GetResponse offers respectable automation, course platform integrations (via API), and built-in webinar hosting. If you're running webinar-to-course funnels, consolidating email + webinar in one tool simplifies your stack.

Pricing is competitive: $15.60/month at 1,000 contacts, which undercuts Kit's post-2025 pricing.

Who it fits: Course creators who rely heavily on webinar funnels and want email + webinar hosting in one platform.

Real downsides: Interface feels dated compared to Kit or MailerLite. Automation builder works but isn't as intuitive.

Course platform integrations exist but require API setup or Zapier—not as plug-and-play as Kit's native connections.

Pricing: Free (500 contacts), $15.60/month (1,000 contacts), scaling to ~$99/month at 10,000 contacts.

Honest take: GetResponse is a solid "B+" tool—it does everything competently but nothing exceptionally. If webinar hosting matters and you want to save money vs Kit, it's worth testing. Otherwise, Kit or MailerLite are clearer choices.

The Honest Verdict: Who Should Pick What

Choose Kit if: You're using Teachable, Thinkific, or Podia for course hosting, you launch 2-4 times per year, and you need reliable automation for launch sequences and student onboarding. Yes, the September 2025 price increase stings, but the native integrations and tag-based automation still make it the best tool for serious course creators. Budget $29-149/month depending on list size.

Choose MailerLite if: You're pre-revenue, testing your first course idea, and need a free tool to start building your list. Accept that you'll likely migrate to Kit or an all-in-one once you're making consistent sales and need better course platform integration.

Choose systeme.io if: You're a solo creator launching your first course and want everything (email, course hosting, checkout) in one simple tool. The $27/month Startup plan is hard to beat for beginners who value simplicity over best-in-class features.

Choose Kartra if: You're doing $10K+/month in course revenue, running a membership site, managing affiliates, and tired of integrating five separate tools. The $119/month investment makes sense when consolidation saves you 10+ hours per month in maintenance.

Skip the expensive option if: You're pre-launch or doing under $1K/month in course revenue. Start with MailerLite's free plan or Systeme.io's free tier. Spending $33-59/month on email marketing before you're making sales is backwards—invest that money in course creation or paid traffic instead.

Avoid Flodesk, GetResponse, and ActiveCampaign for course sales unless: You have specific needs (Flodesk for design-first brands, GetResponse for webinar funnels, ActiveCampaign for complex CRM). For most course creators, they're either overkill or missing critical course-specific features.

Final Recommendation

If you're using Teachable or Thinkific and making consistent course sales, *Kit* remains the best fit despite the 2025 price increase. The native integrations, tag-based automation, and creator-specific features justify the cost once you're past the testing phase.

If you're just starting out and want to minimize costs while you validate your course idea, MailerLite's free plan gives you 1,000 subscribers and basic automation to test your lead magnet and first mini-course.

If you want maximum simplicity and don't mind trading best-in-class email features for all-in-one convenience, systeme.io at $27/month bundles email, course hosting, and checkout in one beginner-friendly platform.

The worst move? Paying for an expensive tool before you've made your first course sale. Start free, validate your offer, then upgrade to the tool that fits your revenue and technical needs.
