If you're selling online courses, your email platform isn't just for newsletters—it's your primary sales engine. You need automation that converts browsers into buyers, onboards new students automatically when they purchase, and nurtures your list between launches without breaking the bank during quiet months.

The challenge: most email platforms charge you monthly for your entire contact list, even if you only launch 3-4 times per year. And connecting your course platform (Teachable, Thinkific, Kajabi) to your email tool often requires fragile integrations that break at the worst possible moment—right when a new student expects their welcome sequence.

This guide walks through the platforms course creators actually use, what each one genuinely excels at, their real limitations, and exactly who should pick what. By the end, you'll know whether you need a specialized email tool or an all-in-one platform, and which pricing model won't punish your launch schedule.

Quick Comparison

Kit (Formerly ConvertKit): The Creator-Friendly Standard

Kit built its reputation specifically for creators—bloggers, podcasters, and course sellers. The visual automation builder is genuinely intuitive, and the free plan up to 10,000 subscribers is unusually generous for this category.

What it's actually good at: The visual automation canvas makes building enrollment sequences straightforward. You can see the entire student journey—from lead magnet to course purchase to post-purchase onboarding—in one visual map. Tag-based subscriber management means you can segment by behavior (clicked sales page, attended webinar, purchased Course A) without wrestling with complex list architecture.

Native integrations with Teachable, Thinkific, and Podia mean when someone buys your course, they automatically enter your onboarding sequence without Zapier. That reliability matters when you're sleeping and students are enrolling at 2am.

Who it fits: Course creators who want powerful automation without a steep learning curve. If you're migrating from Mailchimp and found it clunky, Kit feels like a relief. The free tier genuinely works for creators building their first course with under 10k subscribers—you get basic automation and landing pages included.

Real downsides: Contact-based pricing hurts if you launch sporadically. At 5,000 subscribers, you're paying $79/month year-round even if you only send heavy email during three launch windows. A creator with 15,000 subscribers pays around $149/month whether they send daily or barely touch the platform for months.

The Creator plan ($39/mo starting point) is required for unlimited automations, which you'll need for any real course business. The free plan caps you at one automation, making it essentially a trial for course sellers.

Pricing reality: Free up to 10k subscribers (severely limited automation). Creator plan starts at $39/mo for 1,000 subscribers (around $33/mo annual billing) with unlimited automation. At 5k subscribers: $79/mo. At 10k: $129/mo. At 25k: $259/mo.

MailerLite: The Budget Option That Actually Works

MailerLite consistently wins on price, and unlike most "cheap" tools, it doesn't feel crippled. The interface is clean, automation works reliably, and the free tier (1,000 subscribers) includes basic automation—rare in this price range.

What it's actually good at: Keeping your costs low while you build. At $9/mo for 500 subscribers, it's roughly a third the cost of Kit or ActiveCampaign. The drag-and-drop email builder is straightforward, and deliverability is solid. For creators just starting out or running a single evergreen course, it handles the basics without drama.

The automation features are simpler than competitors, but that can be a feature—fewer options mean less decision paralysis. You can build a purchase-triggered welcome sequence, a cart abandonment series, and behavior-based segments without drowning in options.

Who it fits: New course creators testing their first launch, or established creators with simple automation needs who resent paying $100+/month for features they don't use. If your course business is "send a launch sequence four times a year and weekly newsletters in between," MailerLite handles it fine.

Real downsides: Course platform integrations are limited. Teachable and Thinkific require Zapier bridges, adding $20-30/month and another point of failure. When that Zapier connection breaks during a launch (and it will, eventually), you're troubleshooting integrations instead of selling.

Conditional automation logic lags behind ActiveCampaign and Kit. You can't easily build "if they clicked the sales page but didn't buy, send this; if they never opened, send that" branching logic. It's more linear: Step 1, wait, Step 2, wait, Step 3.

Pricing reality: Free up to 1k subscribers (includes basic automation). Paid plans start at $9/mo for 500 subscribers, $18/mo for 1k, $36/mo for 5k. Still significantly cheaper than competitors at scale—$72/mo at 10k subscribers versus Kit's $129/mo.

ActiveCampaign: The Automation Powerhouse

ActiveCampaign brings CRM-level sophistication to email marketing. If you've used other platforms and felt limited by their automation logic, ActiveCampaign feels like taking the training wheels off.

What it's actually good at: Deeply conditional automation. You can build sequences that branch based on dozens of criteria: did they click the sales page, did they watch the webinar replay, have they purchased before, what's their engagement score, how many emails have they opened in the last 30 days. For course creators with multiple products and complex funnels, this granularity converts better than simple linear sequences.

The built-in CRM tracks each contact's full history—every page visit, email opened, course purchased. When you're emailing about Course B, you can exclude everyone who already bought it or create a special offer for Course A buyers. This level of segmentation directly impacts revenue.

Native integrations with Teachable, Thinkific, and Kajabi are robust and well-maintained. Purchase events sync reliably, and you can trigger different onboarding sequences based on which specific course someone bought.

Who it fits: Course creators treating this as a real business, not a side project. If you're launching multiple courses, running evergreen funnels, and need to track customer lifetime value across products, ActiveCampaign's CRM features justify the cost. It's the tool you grow into when MailerLite feels limiting.

Real downsides: The useful features aren't on the Starter plan. You need the Plus plan (around $49/mo starting point) to get conditional automation, CRM functionality, and contact scoring—the features that make ActiveCampaign worth it. The Starter plan is essentially a trial tier.

The interface has a learning curve. Where Kit feels intuitive immediately, ActiveCampaign requires investment to master. Budget time for setup and learning, or expect to hire help.

Pricing reality: Starter plan starts around $15/mo for small lists but lacks the automation depth you need. Plus plan (required for real use) starts around $49/mo for 1,000 contacts, $99/mo at 2,500 contacts, $179/mo at 5,000 contacts. The price jumps are significant.

GetResponse: The Webinar Wild Card

GetResponse positions itself as an all-in-one marketing platform, but its standout feature for course creators is built-in webinar hosting—something competitors charge separately for or don't offer at all.

What it's actually good at: If your course launch strategy includes live or automated webinars, GetResponse bundles the webinar platform with email automation. You can register attendees, send reminder sequences, host the webinar, and trigger purchase sequences—all in one tool. That integration eliminates the fragile connections between Zoom/WebinarJam and your ESP.

The automation features are solid (though not as deep as ActiveCampaign). You can build behavior-based sequences, segment by engagement, and create conditional workflows. For most course creators, it's enough power without overwhelming complexity.

Who it fits: Creators who sell primarily through webinars and want to consolidate tools. If you're currently paying for Zoom/WebinarJam ($40-80/mo) plus an ESP ($40-100/mo), GetResponse's $59/mo Webinar plan (includes webinars for up to 100 attendees) potentially saves money while simplifying your stack.

Real downsides: Webinar functionality only appears on the $59/mo tier and up—the $19/mo Starter plan doesn't include it, making the headline pricing misleading for the webinar use case. At that price point, you're competing with ActiveCampaign Plus, which has deeper automation.

Course platform integrations exist (Teachable, Thinkific) but aren't as polished as Kit's or ActiveCampaign's. Expect occasional hiccups that require support tickets.

Pricing reality: Starter plan at $19/mo for 1k contacts (no webinars). Webinar plan at $59/mo for 1k contacts (up to 100 webinar attendees). At 5k contacts: $119/mo with webinars. The value proposition depends heavily on whether you'd otherwise pay separately for webinar hosting.

systeme.io: The All-in-One Budget Play

Systeme.io takes a different approach: instead of best-in-class email paired with separate course hosting, it bundles email, course hosting, checkout, and funnels in one platform at a lower total cost.

What it's actually good at: Eliminating integration headaches entirely. When your course platform and email platform are the same tool, purchase-triggered onboarding sequences just work—no Zapier, no API connections to break, no troubleshooting at midnight during a launch.

The pricing model is generous: $27/mo for unlimited contacts and unlimited email sends. For creators with larger lists (10k+) who launch sporadically, this is dramatically cheaper than contact-based pricing. A 15k-subscriber list would cost $149/mo on Kit but stays $27/mo on Systeme.io regardless of list size.

The free tier (2,000 contacts) actually includes course hosting and basic automation—rare in this category. You could genuinely launch your first course without paying anything.

Who it fits: Beginners who want simplicity over sophistication, or experienced creators with large lists who resent paying contact-based pricing for sporadic sending. If you're starting from scratch and don't have existing tools to migrate from, Systeme.io's all-in-one approach eliminates a lot of decision paralysis.

Real downsides: The email automation features lag 1-2 years behind specialist ESPs. You can build basic sequences and segment by tags, but the conditional logic and behavioral triggers aren't as sophisticated as ActiveCampaign or even Kit. For simple course businesses this doesn't matter; for complex multi-product funnels, you'll feel the limitations.

The course platform itself is functional but basic. If you're used to Teachable's polish or Kajabi's features, Systeme.io feels bare-bones. It works, but it's not delightful.

Migration is harder later. If you outgrow Systeme.io and want to move to specialized best-in-class tools, you're migrating both your email platform and your course platform simultaneously—double the complexity.

Pricing reality: Free up to 2k contacts (includes courses, automation, checkout). Startup plan $27/mo (unlimited contacts, unlimited sends). Webinar plan $47/mo (adds webinar hosting). Unlimited plan $97/mo (removes all limits). The value proposition is strongest for larger lists—at 15k+ subscribers, you're saving $50-150/mo versus contact-based competitors.

Kartra: The High-End All-in-One

Kartra bundles everything—email, courses, membership sites, checkout, affiliate management, helpdesk, calendar—into one comprehensive platform. It's the opposite of Systeme.io's simplicity: powerful, complex, and expensive.

What it's actually good at: Supporting established course businesses with complex needs. If you're running multiple courses, a membership site, an affiliate program, and need sophisticated funnel tracking across all of it, Kartra provides that depth. The built-in affiliate management alone would cost $50-100/mo as a separate tool.

Like Systeme.io, the all-in-one approach eliminates integration fragility. But Kartra's automation capabilities are significantly more advanced—closer to ActiveCampaign's depth while still being built into the same platform as your courses.

Who it fits: Course creators already making $5k+/month who need enterprise features without enterprise complexity. If you're managing affiliates, running a membership site alongside courses, and need detailed funnel analytics, Kartra's $119/mo starts looking reasonable compared to buying five separate tools.

Real downsides: The $119/mo starting price is steep for beginners or creators testing their first course. You're paying for features you don't need yet, betting you'll grow into them.

The learning curve is significant. Kartra is powerful because it's comprehensive, but that means more complexity to master. Budget time for setup or plan to hire a Kartra specialist.

No free tier and no monthly trial—you get a 14-day trial, then commit to annual billing for the best rates. That's a bigger commitment than competitors who let you test monthly.

Pricing reality: Starter plan $119/mo (2,500 contacts, 15,000 emails/month). Silver plan $229/mo (12,500 contacts, 125,000 emails/month). The pricing is clearer than it seems—you're replacing email ESP ($50-100/mo) + course platform ($39-119/mo) + checkout/payment processor fees + affiliate software ($50+/mo). For the right business, it's actually consolidation savings.

Moosend: The Underdog Worth Considering

Moosend rarely appears in "best of" lists, but it deserves mention for one specific use case: course creators with large lists who need solid automation without premium pricing.

What it's actually good at: Delivering ActiveCampaign-style automation features at MailerLite-style pricing. The visual automation builder is surprisingly sophisticated—conditional splits, behavioral triggers, engagement scoring—at a price point that undercuts better-known competitors by 30-40%.

At $9/mo for 500 subscribers (same as MailerLite's starting price), you get automation features that would require ActiveCampaign's $49/mo Plus plan. The value gap widens at scale: 10k subscribers costs $80/mo on Moosend versus $129/mo on Kit or $179/mo on ActiveCampaign Plus.

Who it fits: Course creators who need sophisticated automation but balk at ActiveCampaign's pricing. If you've outgrown MailerLite's simple automation but can't justify $180/mo for ActiveCampaign, Moosend sits in that gap.

Real downsides: Course platform integrations are weak. You'll need Zapier for Teachable, Thinkific, and most course hosts, adding cost and fragility. This is Moosend's Achilles heel for course creators—the email features are solid, but connecting to your course platform is clunky.

Brand recognition matters for deliverability. Moosend's infrastructure is fine, but when troubleshooting delivery issues with ISPs, you're explaining what Moosend is rather than working with a known entity like ActiveCampaign or Mailchimp.

Pricing reality: Free trial (no ongoing free tier). Pro plan starts at $9/mo for 500 subscribers, $16/mo for 1k, $80/mo for 10k. The pricing is genuinely competitive, but factor in Zapier costs if you need course platform integration.

The All-in-One Alternatives: ClickFunnels and Others

ClickFunnels, Kajabi, and similar platforms bundle courses, email, and funnels but optimize for different priorities than email-first tools.

ClickFunnels ($147/mo+) excels at funnel building and checkout optimization but treats email as a secondary feature. If your course business is primarily funnel-driven and email is just one component, it works. If email automation is your primary sales engine, you'll feel constrained by the email features and end up adding a specialized ESP anyway.

Kajabi ($149/mo+) is the premium all-in-one, with polished course delivery and solid email automation. It's genuinely good at everything but expensive—justified only if you're already making significant revenue and value the unified experience over best-in-class individual tools.

These platforms make sense when funnel building or course delivery is your priority and email is supporting infrastructure. If email automation is your primary sales mechanism, specialist tools give you more power per dollar.

When to Skip All of These: The Free-Tool Reality Check

If you're pre-launch with no subscribers yet, or testing your first course idea with a tiny list (under 500), you don't need to pay anything yet:

• Kit's free plan (10k subscribers, limited automation) is genuinely usable for simple course launches. You can build one automation sequence, send broadcasts, and create landing pages. That's enough to validate your first course.

• Systeme.io's free tier (2k contacts) includes course hosting and basic automation. You could literally launch your first course, host it, collect payment, and send onboarding emails without paying anything.

• MailerLite's free tier (1k subscribers) includes automation. For a first launch to a small list, it's fully functional.

Don't pay for tools before you need them. Launch your first course on free tiers, validate that people will buy, then upgrade when you're constrained by limits or need sophisticated features. Paying $39-119/mo before you've made your first sale is backwards.

Verdict: Who Should Pick What

Pick Kit if: You want creator-friendly automation that just works, value visual workflow building, and can afford contact-based pricing. Best for creators with under 10k subscribers who launch regularly (monthly or quarterly) and want reliable course platform integrations. Skip it if you have a large list (15k+) but only launch 3-4 times per year—you'll overpay for months of inactivity.

Pick MailerLite if: Budget is your primary constraint and your automation needs are straightforward. Best for new course creators testing their first launch, or established creators with simple evergreen funnels who don't need advanced conditional logic. Skip it if you need sophisticated behavioral automation or hate dealing with Zapier for course platform integration.

Pick ActiveCampaign if: You need CRM-level sophistication, run multiple courses with complex segmentation, and email automation is a core revenue driver worth investing in. Best for course businesses doing $3k+/month who've outgrown simpler tools. Skip it if you're just starting out or your launches are simple—you'll pay for power you don't need yet.

Pick GetResponse if: Webinars are central to your launch strategy and you want to consolidate webinar hosting with email automation. Best for creators currently paying separately for Zoom/WebinarJam and an ESP. Skip it if you don't run webinars—you're paying for features you won't use.

Pick Systeme.io if: You're starting from scratch and want everything in one place, or you have a large list (10k+) with sporadic sending and resent contact-based pricing. Best for beginners wanting simplicity or experienced creators optimizing costs. Skip it if you need cutting-edge automation features or plan to scale to multiple specialized tools eventually.

Pick Kartra if: You're running an established course business ($5k+/month) with complex needs: multiple courses, membership site, affiliate program, and sophisticated funnels. Best for creators consolidating from multiple tools into one powerful platform. Skip it if you're just starting out or your course business is still a side project—it's too expensive and complex for that stage.

Pick Moosend if: You need sophisticated automation on a budget and don't mind Zapier bridges for course platform integration. Best for creators who've outgrown MailerLite but can't justify ActiveCampaign's pricing. Skip it if seamless course platform integration is critical—the weak native integrations will frustrate you.

Final Recommendation

For most course creators reading this, start with Kit's free tier if you're under 10k subscribers or Systeme.io's free tier if you're just launching. Validate your course, make your first sales, and see which features you actually need versus which sounded important in theory.

When you're ready to upgrade (you're constrained by limits or need advanced features), the decision splits:

• If email automation is your primary sales engine and you value polish and reliability: Kit at the Creator plan level ($39/mo+).
• If you need sophisticated conditional automation and CRM features: ActiveCampaign Plus ($49/mo+).
• If you want everything in one place at the lowest total cost: Systeme.io Startup ($27/mo).

The wrong choice isn't picking a suboptimal tool—it's paying for features you don't need yet or staying on free tiers so long you leave money on the table. Launch on free, upgrade when you're constrained, and let revenue—not feature lists—drive your decision.
