Course sellers are not newsletter writers. The overlap is real — most course creators do run newsletters — but the priorities are completely different, and picking the wrong email platform costs you money in missed automation, lost leads, and manual work that should be handled automatically.
This guide is specifically for people who sell courses. Not for people who primarily send broadcast newsletters and happen to mention their course sometimes.
1. What Course Sellers Actually Need From Email
A newsletter writer needs: a good editor, a clean subscriber list, and reliable deliverability. That’s it.
A course seller needs all of that, plus:
Welcome sequences. Someone opts in for your lead magnet → they get a 5-email nurture sequence over 10 days → they get your course pitch at the end. This is the bread-and-butter of online course sales. Without automation sequences, you’re leaving money on the table every single day.
Behavioral tagging. Did someone click the “I’m interested in advanced strategies” link? Tag them. Are they on your free tier? Tag them. Did they buy Course A? Tag them so they don’t get Course A emails anymore, and get Course B upsell instead. Tagging without automation is just data collection. Tagging with automation is a sales machine.
Segmentation. The ability to send different emails to different groups based on what they bought, where they signed up, or what they clicked. An email about your beginner course shouldn’t go to someone who’s already in your advanced cohort.
Course platform integration. When someone buys your course on Teachable, Kajabi, or Thinkific, that action needs to trigger something in your email platform — a tag, a welcome sequence, an upsell automation. If you have to manually export from your course platform and import to your email tool weekly, your setup is broken.
Sales pages for email subscribers. Some course sellers use their email platform to also host landing pages and product pages. This isn’t essential if you’re using Kajabi (which does this natively), but it’s a real convenience feature if you’re on a simpler course platform.
What course sellers don’t need as much: network discovery, a reader app, or built-in sponsorship networks. Those are newsletter-first features.

3. Kit (ConvertKit): Built for Creators, Automation-First
Best for: Course sellers with under 10,000 subscribers who want powerful automation without the complexity of ActiveCampaign.
Kit (formerly ConvertKit) was built specifically for independent creators — bloggers, course sellers, coaches, and newsletter writers who also sell things. It’s the most natural fit for most course sellers at the 0–25k subscriber range.
What Kit does well for course sellers:
Visual automation builder. Kit’s automation builder is genuinely good. You can set up if/then logic visually: “If someone buys Course A → remove from Course A pitch sequence → add to Course B upsell sequence → wait 7 days → send offer.” This is exactly what course sellers need, and Kit makes it approachable without an agency.
Subscriber tagging. Everything in Kit is tag-based. Tags trigger automations, tags define segments, tags control who sees what. It’s the right mental model for course sales.
Native integrations. Kit has a native integration available with Teachable — check Kit’s integration directory for current status — plus Thinkific, Podia, and dozens of other course platforms. When someone buys, the tag fires automatically.
Commerce. Kit has its own digital product and paid newsletter functionality, so if you want to sell products directly through Kit, you can. Transaction fee is 3.5% + 30¢ per transaction.
Free tier. Kit’s Newsletter plan is free for up to 10,000 subscribers. The catch: you’re limited to 1 automation sequence on the free plan. For a course seller, you need the Creator plan ($33/month annually) to unlock unlimited automations.
Kit pricing for course sellers:
- Free (Newsletter): Up to 10,000 subs, 1 sequence — not enough for course sales
- Creator: $33/month (annual) — unlimited automations, visual builder, tagging ← what you actually need
- Pro: $66/month (annual) — adds subscriber engagement scoring, newsletter referral system
Note: Kit charges for all subscribers including unconfirmed — this is a known gotcha as your list grows. Check your confirmed subscriber count before upgrading tiers.
Honest limitation: Kit’s email design is minimal — intentionally so. Some course sellers want beautiful branded emails. Kit is not the tool for that. It’s optimized for plain-text newsletters that convert, not HTML-heavy promotional emails.
4. ActiveCampaign: Most Powerful Automation, Higher Price
Best for: Course sellers with complex funnels, larger lists (10k+), or multiple course products requiring sophisticated segmentation and lead scoring.
ActiveCampaign is the most powerful email automation platform in this comparison. If you’ve ever tried to build something in Kit and felt limited, ActiveCampaign can almost certainly do it.
What ActiveCampaign does better than everyone else:
Automation depth. Conditional branches, wait-for-behavior steps, predictive sending, lead scoring — AC’s automation builder is the gold standard. A 15-step course launch sequence with behavioral branching based on opens, clicks, purchase history, and tag status? ActiveCampaign handles it cleanly.
CRM integration. ActiveCampaign includes a built-in CRM with deal tracking. If you’re doing high-ticket courses with a sales call component, this matters. Kit doesn’t have a native CRM.
Site tracking. AC can track what pages your subscribers visit on your website, then trigger automations based on that behavior. Someone visited your course sales page 3 times but didn’t buy? Trigger a special offer email.
ActiveCampaign pricing: Pricing starts higher than alternatives; check activecampaign.com for current rates. There’s no permanent free tier. Most course sellers at under 10k subscribers are better served by Kit.
Honest limitation: ActiveCampaign has a real learning curve. If you’re not technical and you don’t have time to invest in setting it up properly, you’ll pay for features you never use.
5. MailerLite: Best Budget Option for Course Sellers
Best for: Course sellers at under 5,000 subscribers who want solid automation at the lowest possible price.
MailerLite has quietly become a serious contender. Its automation builder isn’t as powerful as Kit’s, but it’s good enough for a standard course launch sequence, and the price is significantly lower.
MailerLite pricing (course sellers):
- Free: Up to 500 subscribers, 12,000 emails/month — legitimate free tier
- Growing Business: from ~$10/mo (varies by list size — check mailerlite.com for your subscriber count)
- Advanced: check mailerlite.com for current rates — adds custom HTML, unlimited seats, advanced website features
What MailerLite does well:
- Automation sequences with triggers, conditions, and actions
- Tagging and segmentation (solid for the price)
- Landing pages and website builder included
- Sell digital products and paid newsletters (Advanced plan)
- Excellent deliverability for its price tier
- 24/7 support on paid plans
Honest limitation: MailerLite’s integrations are thinner than Kit’s. You’ll need Zapier for most course platform connections. The automation builder is functional but less intuitive than Kit’s visual builder. For a course seller with a complex funnel, it can get unwieldy.
6. beehiiv: Newsletter-Native, Limited Automation
Best for: Course sellers who primarily want a great newsletter to drive traffic and brand awareness to their courses — not for course-specific automation.
Let’s be direct: beehiiv is a newsletter platform, not a course seller platform. It wasn’t designed with course funnels in mind, and it shows.
What beehiiv can do:
- Email automations on Scale plan ($43/month) — welcome sequences, basic triggers
- Subscriber tagging (limited vs Kit or AC)
- Excellent newsletter UX and deliverability
- Ad network and referral program if you want to grow your newsletter audience
What beehiiv can’t do well:
- Complex behavioral automation with branching logic
- Deep course platform integration
- Lead scoring or CRM functionality
- Behavioral site tracking
Honest verdict for course sellers: If your course is one thing you sell and your newsletter is the main thing you do, beehiiv is fine. You’ll handle course-specific sequences manually or with a very light automation setup. If email automation is central to your course sales model, beehiiv will frustrate you.
7. Mailchimp: Familiar But the Wrong Tool for Courses
Mailchimp was the original email marketing platform. Many course sellers default to it because they’ve heard of it. That’s not a good reason.
Why Mailchimp underperforms for course sellers:
- Charges for unsubscribed contacts. If someone unsubscribes, Mailchimp keeps counting them against your plan limit unless you manually clean them. This inflates your effective cost significantly.
- Contact-based pricing is expensive at scale. Mailchimp’s Standard plan starts from $13–20/mo depending on list size — check mailchimp.com, but climbs steeply as your list grows.
- Automation is improving but still behind Kit. Mailchimp’s automations (called “Customer Journeys”) have improved in recent years, but the interface is clunkier than Kit’s visual builder.
- Free tier capped at 250 contacts. This used to be 2,000 — the reduction is significant and removes Mailchimp’s biggest competitive advantage for early-stage creators.
When Mailchimp still makes sense: If you’re on Mailchimp already, have an existing team trained on it, and your list is under 10k — the switching cost may not be worth it. But if you’re starting fresh, choose Kit or MailerLite instead.
8. Decision Guide by Course Platform
Running on Teachable → Use Kit
Kit has a native integration available with Teachable — check Kit’s integration directory for current status. When someone purchases on Teachable, their tag and automation trigger in Kit without needing Zapier. This is the smoothest course-seller setup.
Running on Kajabi → Consider ActiveCampaign
Kajabi users tend to have more complex funnels and higher-ticket offers. Kajabi integrates with ActiveCampaign. If you’re using Kajabi, you likely need AC’s CRM and advanced automation capabilities.
Running on Podia → Use MailerLite
Podia users are often earlier-stage course sellers watching budget. MailerLite’s price point and solid automation at the Growing Business tier is a natural fit. Connect via Zapier.
Running on Thinkific → Use Kit or MailerLite
Thinkific has integrations with both. Kit if you value the visual automation builder; MailerLite if you’re price-sensitive.
Running on Gumroad → Use Kit or MailerLite
Gumroad’s integrations are primarily via Zapier. Both Kit and MailerLite work cleanly through Zapier.
Running a cohort-based course → Use ActiveCampaign
High-touch cohort courses with sales calls, follow-ups, and CRM needs → ActiveCampaign.
9. Bottom Line
The honest ranking for course sellers:
- Kit — Best overall for 90% of course sellers. Great automation, native integrations, fair pricing, free up to 10k subscribers (though you need Creator plan at $33/mo for unlimited automations). Note: Kit charges for all subscribers including unconfirmed — watch this as your list grows.
- ActiveCampaign — Best for complex funnels and larger lists. Worth it if you’ve outgrown Kit.
- MailerLite — Best budget option. Gets you 80% of Kit’s functionality at a lower price point, especially for smaller lists.
- beehiiv — Good if your newsletter is the main product and courses are secondary. Not designed for course funnels.
- Mailchimp — Avoid for new setups. The contact-counting on unsubscribes will cost you more than you expect.
Never pick a platform without thinking about subscriber growth. Both Mailchimp and Kit charge more as your list grows. MailerLite does too. beehiiv has flat pricing at $43/month up to 100k subscribers on Scale — unusual in this space and worth knowing.
Pricing verified March 2026. Check vendor site before purchasing — email platform pricing changes frequently, especially at subscriber milestones.
