If you're a course creator with under 1,000 subscribers, you're in a frustrating pricing zone. You need real automation to nurture leads and sell courses, but most email platforms either charge you like you're running a media empire or lock essential features behind paid tiers that feel punitive at your size.

The right tool for you isn't the one with the most features—it's the one that gives you functional automation, decent deliverability, and direct product sales without bleeding you dry while you're still building. This guide compares the platforms course creators actually consider, with honest pricing breakdowns and real limitations you need to know before you commit.

By the end, you'll know exactly which tool fits your budget, technical comfort level, and how you actually plan to sell—whether that's evergreen funnels, live launches, or paid newsletters.

Quick Comparison: Email Tools for Small Course Creator Lists

Kit (Formerly ConvertKit): The Course Creator Default—But Now Expensive

Kit built its reputation as the email tool for creators selling digital products, and for good reason: its tag-based subscriber model and visual automation builder were designed specifically for course launch funnels, not corporate newsletters.

What makes Kit genuinely good:

The tag system is the killer feature for course creators. Instead of managing separate lists for each lead magnet (and paying for duplicate subscribers across lists), Kit tracks one subscriber record and applies tags as they move through your funnel. Someone downloads your free mini-course, gets tagged. They buy your $47 starter course, different tag. This means you can segment and automate without the billing nightmare of traditional list-based platforms where the same person counts multiple times.

The visual automation builder (available on paid plans) is intuitive enough for non-technical creators but powerful enough for sophisticated evergreen funnels. You can trigger sequences based on link clicks, tag additions, product purchases, or form submissions—all the logic you need for a self-running course funnel.

Kit Commerce lets you sell digital products, paid newsletters, and tip jars directly through the platform. On the free tier, you pay 3.5% + 30¢ per transaction (plus Stripe fees); on the Creator tier ($33/month), it drops to 3.5%; on Creator Pro ($66/month), the platform fee disappears entirely. If you're selling a $97 course, that's meaningful—$3.40 vs. $0 in platform fees per sale.

Real downsides you need to know:

The September 2025 price increase was brutal. Kit raised its Creator tier (the one you actually need for functional automation) from $15/month to $33/month for 1,000 subscribers—a 120% jump. For course creators just starting out, that $33 monthly is a real budget line, especially compared to MailerLite at roughly $10/month for the same list size.

The free tier sounds generous (10,000 subscribers!), but it's deliberately crippled for course creators. You get exactly one automation, no integrations with Teachable, Thinkific, Shopify, Zapier, or WordPress, and no ability to remove Kit branding. If you're running any kind of real funnel—welcome sequence, abandoned cart, post-purchase nurture—you'll hit that one-automation limit instantly and be forced to upgrade.

The email editor is minimalist to a fault. Kit offers roughly 15 basic templates, all text-focused and plain. If you want branded, multi-column layouts with rich imagery and sophisticated design, you'll be frustrated. Kit's philosophy is "simple emails convert better," which is often true—but the lack of flexibility feels limiting when you're trying to match your course branding.

Advanced features like subscriber scoring and detailed engagement analytics are locked behind the Creator Pro tier at $66/month for 1,000 subscribers. Paying that much just to see who's engaged feels backwards for a platform built around audience relationships.

Who should use Kit:

You're running (or planning) a tag-based evergreen funnel with multiple lead magnets feeding into paid courses. You value automation logic over email design. You're willing to pay the $33/month "simplicity premium" for a platform that won't nickel-and-dime you with duplicate subscriber charges as your funnel grows. And you want to sell digital products directly without bolting on Gumroad or ThriveCart.

Who should skip it:

You're just starting and need to validate your course idea on a tight budget—MailerLite gives you the same core automation for one-third the price. Or you're a design-focused creator who needs beautiful, branded emails—Flodesk or Beehiiv will make you happier. Or your list is growing fast and predictably—Flodesk's flat rate becomes cheaper once you pass ~1,200 subscribers.

Rough pricing: Free up to 10,000 subscribers (severe feature limits); $33/month for 1,000 subscribers on Creator tier; $66/month for Creator Pro with zero platform fees on sales.

Beehiiv: Newsletter-First With Strong Free Tier

Beehiiv launched as a Substack alternative for creators who wanted more control, and it shows in every design decision. This is a publication platform with email marketing bolted on, not the other way around.

What makes Beehiiv genuinely good:

The free tier is the most generous for newsletter-focused creators: 2,500 subscribers with growth tools, basic automation, and a referral program included. If you're under 1,000 subscribers and plan to grow via word-of-mouth and content quality, Beehiiv lets you do that without paying a dime until you hit 2,500.

The built-in referral program is native and powerful—readers can share your newsletter and unlock rewards (bonus content, free courses, etc.) automatically. For course creators, this is gold: your best students become your growth engine. Kit and MailerLite require third-party integrations (SparkLoop, Upscribe) to replicate this.

The email editor is modern and flexible without being overwhelming. You get polls, content recommendations, and ad network options (if you want to monetize via ads while building your course). The UX feels like a blogging platform—clean, fast, intuitive for people who think in "posts" rather than "campaigns."

Paid newsletter subscriptions are built-in on paid plans, so you can run a paid membership tier alongside your free newsletter. If your course business model includes a paid community or premium content layer, Beehiiv handles it natively.

Real downsides you need to know:

Automation is basic compared to Kit. You can build welcome sequences and tag-based sends, but the visual builder isn't as robust for complex conditional logic. If your course funnel requires "if they clicked this link but didn't buy within 3 days, send this sequence"—Kit's automation is more powerful.

Beehiiv is newsletter-first, which means it's optimized for publication-style sends (weekly deep-dives, curated content) rather than product funnels. If you're selling courses via evergreen sequences and tripwires, the platform feels slightly off-angle. It'll work, but Kit's mental model fits better.

Commerce features (selling directly through Beehiiv) require paid plans starting at $39/month. The free tier is great for building an audience, but if you want to sell a paid newsletter or digital product without third-party tools, you're paying more than Kit's $33/month Creator tier.

Integrations are growing but still limited compared to established ESPs. If you're using Teachable, Kajabi, or niche course platforms, you'll likely need Zapier—and Beehiiv's Zapier integration is less mature than Kit's.

Who should use Beehiiv:

You're building a newsletter-driven audience and your course is the natural upsell (not the primary business). You value growth tools like referral programs over deep automation. You're under 2,500 subscribers and want to spend $0 while you validate your content and offer. Or you plan to monetize via both courses and paid subscriptions, and want one platform to handle both.

Who should skip it:

You're running complex, multi-step evergreen funnels with conditional logic—Kit's automation will serve you better. Or you need deep integrations with course platforms and CRMs right now—Beehiiv's ecosystem is still maturing. Or you're not publishing regular newsletter content—if you're only sending sales sequences and product updates, Beehiiv's publication UX is overkill.

Rough pricing: Free up to 2,500 subscribers; $39/month for Grow plan with monetization features; $99/month for Scale plan with advanced analytics.

MailerLite: The Budget Pick That Doesn't Feel Cheap

MailerLite is the unsexy answer that often turns out to be the right one. It's not built specifically for course creators, but it has all the core features you actually need at roughly one-third the cost of Kit.

What makes MailerLite genuinely good:

Pricing is the obvious win: around $10/month for 1,000 subscribers (verify current rates, as they adjust periodically). That's $23/month less than Kit for functionally identical automation at this list size. Over a year, that's $276 saved—real money when you're bootstrapping a course business.

The automation builder is surprisingly capable. You get unlimited automations even on paid plans (unlike Kit's one-automation free tier), with triggers for opens, clicks, dates, and custom fields. You can build welcome sequences, abandoned cart flows (if integrated with e-commerce), and post-purchase nurture—all the standard course funnel logic.

The email editor is more flexible than Kit's, with drag-and-drop design, decent template variety, and the ability to create visually rich emails without coding. If you care about branded course announcements or launch emails that match your visual identity, MailerLite gives you more design freedom.

Landing pages and forms are included and functional. They're not stunning, but they work for lead magnet opt-ins and webinar registrations—the basic infrastructure course creators need.

Real downsides you need to know:

MailerLite uses traditional list-based subscriber management, not Kit's tag system. If you have multiple lead magnets and sequences, the same subscriber can exist on multiple lists and count multiple times toward your billing. This isn't a problem at 1,000 total subscribers, but as you scale, it becomes a hidden cost multiplier that Kit's tag system avoids.

No built-in commerce. If you want to sell digital products or courses directly, you're integrating with Gumroad, ThriveCart, Stripe, or your course platform. That's not necessarily bad—many creators prefer best-of-breed tools—but it adds complexity compared to Kit Commerce or Beehiiv's native options.

The platform isn't purpose-built for creators, so you won't find creator-specific features like referral programs, tip jars, or paid newsletter infrastructure. MailerLite is a general-purpose ESP that happens to be cheap and competent—it won't feel like it was designed for your exact use case the way Kit does.

Deliverability is good but not exceptional. MailerLite's reputation is solid, but Kit's creator-focused sender reputation (fewer spammy marketers, more legitimate creators) can mean slightly better inbox placement for some audiences. The difference is marginal, but worth noting.

Who should use MailerLite:

You're budget-conscious and need functional automation without the $33/month Kit premium. You're comfortable integrating a separate payment processor or course platform for sales. You value email design flexibility over creator-specific features. Or you're not sure your course will succeed and want to minimize fixed costs while you test.

Who should skip it:

You're running a complex tag-based funnel with multiple entry points and want to avoid duplicate subscriber billing—Kit's model is cleaner. Or you want to sell products directly through your email platform without third-party tools—Kit Commerce or Beehiiv are simpler. Or you're scaling fast and the list-based billing will become expensive quickly.

Rough pricing: Around $10/month for 1,000 subscribers on paid plans; free tier available up to 1,000 subscribers with limited features (verify current limits).

Flodesk: Flat-Rate Pricing for Predictable Costs

Flodesk took a contrarian bet: charge one flat rate regardless of list size, and focus on making emails beautiful by default. For course creators with growing lists, the math gets interesting fast.

What makes Flodesk genuinely good:

Flat-rate pricing (currently around $38/month, though verify as they occasionally adjust) means your costs never increase as your list grows. If you're at 800 subscribers today but expect to hit 5,000 next year, Flodesk becomes dramatically cheaper than Kit ($125/month at 5K) or MailerLite (~$50/month at 5K). You can model your business without worrying about email costs scaling with success.

The email editor is the best-looking in this category. Flodesk's templates are modern, image-rich, and on-brand for lifestyle and creative businesses. If your course is in design, photography, wellness, or any visually-driven niche, Flodesk emails will match your brand aesthetic better than Kit's plain-text philosophy.

Automation is unlimited and straightforward. You can build welcome sequences, sales funnels, and date-based campaigns without hitting arbitrary limits or paying for higher tiers. The visual workflow builder is clean and intuitive.

Forms and landing pages are included and genuinely attractive. If you're driving cold traffic to a lead magnet, Flodesk's opt-in pages convert well because they don't look like generic ESP templates.

Real downsides you need to know:

No built-in commerce. Like MailerLite, you're integrating with external tools to sell courses. Flodesk is purely an email and form platform—no native checkout, no paid subscriptions, no tip jars.

Segmentation and tagging are less sophisticated than Kit's. You can segment by behavior and custom fields, but the logic isn't as flexible for complex conditional funnels. If your course business relies on intricate "if/then" automation based on multiple tag combinations, Kit's system is more powerful.

Integrations are limited compared to established ESPs. Flodesk connects with major platforms (Shopify, WordPress, Zapier), but the ecosystem isn't as mature. If you're using niche course platforms or specific CRM tools, double-check compatibility before committing.

The flat rate only makes financial sense if you're growing. At 1,000 subscribers, Flodesk (~$38/month) is more expensive than MailerLite (~$10/month) and comparable to Kit ($33/month) or Beehiiv ($39/month for paid features). The value proposition kicks in above ~1,200 subscribers when other platforms start costing more.

Who should use Flodesk:

You're growing steadily and want predictable costs that don't penalize success. You're in a visually-driven niche where branded, beautiful emails matter for positioning. You're comfortable with external tools for course sales and don't need deep automation logic. Or you've been burned by ESP pricing that doubled as your list grew and want to lock in a flat rate now.

Who should skip it:

You're just starting with a small list and need the cheapest functional option—MailerLite is $28/month less expensive at 1,000 subscribers. Or you need sophisticated tag-based automation for complex funnels—Kit's system is more robust. Or you want built-in commerce to sell directly—Flodesk doesn't offer it.

Rough pricing: Around $38/month flat rate regardless of list size (verify current rate; they occasionally run promotions or adjust pricing).

Other Options Worth Mentioning (And Why They're Usually Wrong)

Substack is free with a 10% revenue cut on paid subscriptions. It's perfect if you're a writer monetizing purely via paid newsletters, but terrible for course creators. You can't build automation, segment meaningfully, or integrate with course platforms. Use it for a paid newsletter business, not a course funnel.

ActiveCampaign offers industrial-strength automation and CRM features, starting around $29/month for 500 contacts. If you need complex multi-touch attribution, lead scoring, and sales pipeline management, it's powerful. But for most course creators under 1,000 subscribers, it's overkill—you're paying for CRM complexity you won't use. Consider it if you're also running a service business or high-touch coaching alongside courses.

Mailchimp has brand recognition but has fallen behind for creators. Pricing is around $13/month for 500 contacts (you'd need the next tier for 1,000), automation is limited on lower plans, and the platform is optimized for e-commerce and small business marketing, not creator funnels. It's fine for simple newsletters, but Kit, Beehiiv, or MailerLite serve course creators better.

systeme.io is an all-in-one platform (email, courses, funnels, websites) with aggressive free-tier pricing. If you want to avoid stitching together separate tools, it's worth evaluating—but the email features are less polished than dedicated ESPs, and you're locked into their ecosystem for course hosting. Consider it if you're starting from absolute zero and want one tool for everything, but expect to outgrow it.

Moosend is another budget ESP (around $9/month for 1,000 subscribers) with solid automation. It's comparable to MailerLite in features and pricing, but with a less intuitive interface and smaller creator community. If MailerLite's pricing or limits don't work for you, Moosend is a reasonable alternative—but it's not differentiated enough to be a primary recommendation.

Verdict: Who Should Pick What

Choose Kit if: - You're running or planning tag-based evergreen funnels with multiple lead magnets and product tiers - You want to sell digital products directly without third-party payment tools - You value automation sophistication over email design flexibility - You're willing to pay $33/month for a platform purpose-built for creators (and can justify the premium over cheaper alternatives) - You expect to scale beyond 1,000 subscribers and want to avoid duplicate billing across lists

Choose Beehiiv if: - You're building a newsletter-first audience and courses are the natural upsell - You're under 2,500 subscribers and want to spend $0 while validating your content - Referral-driven growth is core to your strategy and you want native tools - You plan to monetize via both courses and paid newsletter subscriptions - You're publishing regular content (weekly/biweekly) and want a publication-optimized UX

Choose MailerLite if: - Budget is your primary constraint and you need functional automation for ~$10/month - You're comfortable integrating separate tools for course sales and payments - You want more email design flexibility than Kit offers - You're testing a course idea and need to minimize fixed costs - You don't need creator-specific features like referral programs or native commerce

Choose Flodesk if: - You're growing steadily (or expect to) and want predictable costs that don't scale with list size - Visual branding is critical to your positioning and you need beautiful emails by default - You're comfortable at ~$38/month and plan to scale past 1,500+ subscribers where the flat rate becomes cheaper - You don't need complex automation logic or built-in commerce - You've been burned by ESP pricing that doubled as you grew and want cost certainty

When NOT to buy any of these (and what to do instead):

If you're pre-launch with zero subscribers and just collecting emails for a waitlist, use Kit's free tier (10,000 limit) or Beehiiv's free tier (2,500 limit) until you actually have a funnel to automate. Don't pay for features you're not using yet.

If you're selling exclusively through a course platform (Teachable, Kajabi, Thinkific) that includes email, use their built-in tools first. Only graduate to a dedicated ESP when you need automation those platforms can't handle or want to own your subscriber data independently.

If you're a complete beginner validating your first small course (under $500 in revenue), MailerLite's free tier (up to 1,000 subscribers with limited features) or systeme.io's free all-in-one plan will get you started without monthly costs. Upgrade when you're making consistent sales.

Final Recommendation

For most course creators with under 1,000 subscribers, MailerLite is the honest answer: it's cheap (~$10/month), has the automation you actually need, and doesn't lock essential features behind expensive tiers. You'll save $276/year compared to Kit and can invest that money in ads, course creation, or literally anything else that grows your business faster than a prettier ESP.

But if you're serious about building a tag-based evergreen funnel and selling digital products directly, *Kit* is worth the $33/month premium—the tag system prevents duplicate billing as you scale, and Kit Commerce simplifies your tech stack. Just go in with eyes open about the cost and feature limitations.

If you're newsletter-first and under 2,500 subscribers, Beehiiv's free tier is the no-brainer starting point. You get growth tools, decent automation, and zero monthly cost while you build. Upgrade when you need monetization features or hit the subscriber cap.

And if you're scaling fast or want cost predictability, Flodesk's flat rate becomes the smartest long-term bet once you pass ~1,200 subscribers—but don't overpay for it when you're just starting.

The right tool isn't the one with the most features. It's the one that fits your actual funnel, your real budget, and how you genuinely plan to sell—without bleeding you dry while you're still building.
