If you're selling courses or digital products, your email list is probably your biggest revenue driver. But most email tools were built for e-commerce stores or SaaS companies—not creators who need to nurture leads through a launch sequence, sell without a full course platform, and actually make money from their list without bleeding transaction fees.
This guide compares the email marketing tools that actually matter for course creators and digital product sellers in 2026. By the end, you'll know which platform fits your subscriber count, whether you need built-in commerce or just solid automation, and when you should stick with a free plan versus paying for features that move the needle.
I'm focusing on tools that handle both email marketing and some form of digital sales—because if you're reading this, you're not just building a list for fun. You're building a business.

Kit (Formerly ConvertKit): The Automation-First Choice for Digital Sellers
Kit is the default recommendation in creator circles for a reason: it was purpose-built for people selling digital products through email sequences. The visual automation builder makes it genuinely easy to set up a launch funnel, tag buyers versus non-buyers, and segment your list without needing a computer science degree.
What makes it good for course creators:
The real advantage is the combination of robust automation and low transaction fees. If you're selling a $500 course and you make 100 sales, you'll pay $250 in fees on Kit's Creator plan (0.5%) versus $5,000 on Gumroad or Substack (10%). That math changes everything once you're doing volume.
The free plan is unusually generous—10,000 subscribers with unlimited sends, landing pages, and forms. That's expanded from previous limits in late 2024, making it viable to build a substantial list before paying anything. Most creators can launch their first product and hit initial revenue on the free tier.
Kit Commerce handles the payment processing and delivery for digital products directly. You don't need Gumroad, Teachable, or a separate checkout tool for simple products like PDFs, templates, or self-paced course access. The buyer experience is clean: they click a link in your email, pay, and get instant access.
The visual automation builder is where Kit justifies its price. You can create sequences that tag people based on link clicks, move them between sequences based on purchases, and build conditional logic that feels intuitive. It's not as powerful as ActiveCampaign's deeply nested rules, but it's way easier to use for the 90% of automations creators actually need.
Real downsides:
Pricing escalates fast after you cross 10,000 subscribers. At 5,000 subscribers you're paying around $89/month; at 25,000 you're at roughly $199/month. MailerLite charges about $109/month for 25,000 subscribers—nearly $90 less per month. That gap matters if you're growing a large newsletter without proportional product revenue.
The landing page builder is template-limited. You pick a template and customize within its container structure, but you can't drag elements freely or build truly custom layouts. If you need elaborate sales pages, you'll still want Leadpages or Carrd.
Kit Commerce handles sales and payment, but it doesn't host video courses or create a student dashboard. If you're selling a multi-module video course with progress tracking and certificates, you still need Teachable, Thinkific, or Podia. Kit just handles the email marketing and checkout—you'll integrate it with your course platform.
A/B testing on the Creator plan is subject-line only. You can't test email body content, different CTAs, or send times without upgrading to Creator Pro at $50/month base. For most creators, subject-line testing is enough, but it's a limitation if you're optimizing aggressively.
The email templates are intentionally minimal and text-focused. This is actually good for deliverability—plain-text-style emails land in inboxes better than heavily designed HTML. But if you want visually elaborate newsletters with custom layouts, Flodesk or Beehiiv will feel more flexible.
Pricing breakdown:
- Free: Up to 10,000 subscribers, unlimited sends, 3.5% + $0.30 transaction fee
- Creator: Starts at $25/month for 300 subscribers, scales to ~$89/month at 5,000 and ~$199/month at 25,000. Transaction fee drops to 0.5%.
- Creator Pro: Starts at $50/month base, adds full content A/B testing and subscriber scoring.
Who it fits:
You're selling digital products with meaningful price points (not $5 impulse buys), you need automation to run launches or evergreen funnels, and you're willing to pay for a tool that reduces transaction fees enough to offset its subscription cost. If you're doing $10k+/month in course sales, the 0.5% fee versus 10% alternatives saves you $950/month—way more than Kit's subscription.
Beehiiv: Newsletter Growth Over Course Sales
Beehiiv is the rising star for newsletter creators, with built-in referral programs, recommendation networks, and growth tools that Kit doesn't match. But it's not optimized for selling courses.
What it does well:
The referral program is native and dead simple—readers get a unique link, you set milestone rewards, and Beehiiv tracks it automatically. Kit requires third-party tools or manual workarounds for the same functionality.
The 3D analytics show opens, clicks, and subscriber growth in genuinely useful visualizations. You can see which posts drove the most growth, what topics resonated, and where readers dropped off—without exporting to spreadsheets.
The ad network and premium subscriptions are built in. If you want to monetize through sponsorships or paid tiers rather than selling courses, Beehiiv handles it natively. Kit's Sponsor Network requires 10,000+ subscribers minimum and takes a 23.5% cut; Beehiiv's is more accessible.
Where it falls short for course creators:
No native commerce for one-time digital product sales. You can sell premium newsletter subscriptions, but if you want to sell a $300 course, you're bolting on Gumroad or Teachable and losing the integration benefits.
The free plan caps at 2,500 subscribers versus Kit's 10,000. If you're building a list to eventually sell to, that 7,500-subscriber difference gives you way more runway on Kit.
Automation is simpler and less visual than Kit's. You can set up basic sequences, but the conditional logic and tagging flexibility isn't at the same level. For a weekly newsletter, that's fine. For a launch funnel with multiple buyer paths, it's limiting.
Pricing:
- Free: Up to 2,500 subscribers
- Grow: $49/month for up to 10,000 subscribers
- Scale: $99/month for up to 25,000 subscribers
Who should pick it:
You're building a newsletter first, monetizing through ads or premium subscriptions, and growth mechanics (referrals, recommendations) matter more to you than launch automation. If you're selling courses as the primary business model, Beehiiv isn't the best fit.
Systeme.io: The All-In-One Budget Option
systeme.io is the "everything in one cheap box" choice. You get email marketing, landing pages, sales funnels, course hosting, and affiliate management in a single platform starting at $27/month. The tradeoff is that each piece is less polished than specialized tools.
Why budget-conscious creators consider it:
Zero transaction fees on paid plans. You're not paying 0.5% or 3.5% per sale—the subscription cost is it. For creators doing volume on tight margins, that's appealing.
It includes basic course hosting with video uploads, modules, and student access. You're not paying separately for Teachable or Thinkific. The course builder is bare-bones (no certificates, limited gamification, basic progress tracking), but it works for straightforward video courses.
The free plan allows up to 2,000 contacts, which is more than Moosend (1,000) but less than Kit (10,000). You also get three sales funnels and unlimited email sends on the free tier.
The honest limitations:
The interface feels dated and clunky compared to Kit or Beehiiv. Navigation isn't intuitive, and you'll spend time hunting for settings. It works, but it's not enjoyable to use.
Email deliverability is a common complaint. Users report higher spam rates and lower inbox placement compared to dedicated email tools. If your business depends on emails actually landing, that's a serious risk.
Automation is functional but basic. You can set up sequences and tag-based triggers, but the visual builder is less intuitive than Kit's, and the conditional logic is more limited. For simple funnels it's adequate; for complex segmentation it's frustrating.
The course player and student experience are utilitarian. Students get access to videos and can mark lessons complete, but there's no community features, limited branding customization, and no mobile app. If student experience matters to your brand, you'll feel the limitations.
Pricing:
- Free: Up to 2,000 contacts, 3 sales funnels
- Startup: $27/month for up to 5,000 contacts
- Webinar: $47/month, adds webinar features
- Unlimited: $97/month for unlimited contacts and features
Who it fits:
You're just starting, you need course hosting and email in one place, and you're willing to accept "good enough" tools to avoid paying for multiple subscriptions. If you're doing under $2k/month in revenue and every dollar counts, systeme.io makes sense. Once you're scaling, you'll likely outgrow it.
Moosend: The Budget Email Specialist
Moosend is the low-cost email marketing tool that doesn't try to do commerce or course hosting—it just does email and automation cheaply. Starting at $9/month, it's significantly less expensive than Kit, especially as you scale.
What it does well:
The pricing is genuinely affordable. At 5,000 subscribers you're paying around $32/month versus Kit's $89/month. At 25,000 subscribers, Moosend is roughly $80/month compared to Kit's $199/month. If you're selling through a separate platform (Gumroad, Podia, Teachable) and just need email marketing, that savings compounds.
The automation builder is visual and capable. You can create conditional paths, tag-based triggers, and multi-step sequences without the steep learning curve of ActiveCampaign. It's not as polished as Kit's interface, but it's functional for launch funnels and nurture sequences.
Reporting is solid for the price. You get standard open rates, click rates, and conversion tracking with enough detail to optimize your campaigns. It's not as visually slick as Beehiiv's analytics, but the data is there.
The limitations:
No built-in commerce or course hosting. If you want to sell digital products, you're integrating with Gumroad (10% fees), Podia, or another platform. You lose the unified experience and pay transaction fees elsewhere.
The free plan caps at 1,000 subscribers, which is tight for list building. You'll hit paid territory faster than with Kit (10,000) or even systeme.io (2,000).
Landing page templates are basic and limited. You can build functional opt-in pages, but they won't win design awards. Most creators end up using Carrd or Leadpages for landing pages and Moosend just for email.
Email template design is serviceable but not inspiring. If visual newsletters are core to your brand (like a design or photography creator), you'll feel constrained.
Pricing:
- Free: Up to 1,000 subscribers
- Pro: Starts at $9/month, scales to ~$32/month at 5,000 subscribers and ~$80/month at 25,000 subscribers
Who should pick it:
You're selling through an established course platform (Teachable, Podia, Gumroad) and you just need affordable, capable email marketing. You don't need Kit's integrated commerce because you're already paying for course hosting elsewhere, and saving $100+/month on email matters to your margins.
MailerLite and Flodesk: Honorable Mentions
MailerLite is similar to Moosend—affordable, capable email marketing without built-in commerce. At $10/month starting and roughly $109/month for 25,000 subscribers, it's a strong budget option if you just need email. The interface is cleaner than Moosend's, and deliverability is reliable. But like Moosend, you're bolting on separate tools for sales.
Flodesk costs a flat $38/month regardless of subscriber count, which is amazing value if you're growing past 5,000 subscribers (where Kit hits $89/month). The email templates are the most visually beautiful in this category—genuinely magazine-quality designs. But there's no automation beyond basic sequences, no commerce features, and no course hosting. It's for creators who prioritize email design and have growing lists, not for running launch funnels or selling products directly.
Podia: The Full Course Platform with Email
Podia is a different category—it's a complete course platform that happens to include email marketing, not an email tool that added commerce. You get video hosting, course builders, student dashboards, community features, and email in one platform.
Why course creators consider it:
Zero transaction fees on paid plans. On the free plan you pay 8%, but once you're on the $33/month Mover plan, there are no per-sale fees. For high-volume course sales, that's competitive with Kit's 0.5%.
Full course hosting with a good student experience. Videos stream reliably, students can track progress, you can drip content, and there's a mobile-friendly student dashboard. You're not integrating Kit with Teachable—it's all native.
Email marketing is included and integrated. You can email your students, leads, and buyers from the same platform where they bought and access your course. The automation is simpler than Kit's, but it covers the basics for course launches.
The tradeoffs:
Email marketing and automation are less powerful than Kit's. You can set up sequences and segment your list, but the visual automation builder and conditional logic are more limited. If you need complex funnels, you'll feel the ceiling.
You're locked into Podia's ecosystem. If you later want to switch email tools or course platforms, migration is painful. With Kit + Teachable, you can swap out either piece independently.
The email templates and landing pages are functional but not as flexible as dedicated email tools. You can create what you need, but power users will miss features.
Pricing:
- Free: 8% transaction fee, unlimited everything else
- Mover: $33/month, 0% transaction fees
- Shaker: $75/month, adds affiliate program and bulk discounts
Who it fits:
You want one platform for everything (courses, email, sales) and you're okay with "good enough" email marketing in exchange for not managing multiple tools. If you're just starting and want simplicity over power, Podia makes sense. If you're scaling and email marketing drives your revenue, Kit's automation will be worth the extra complexity.
The Honest Verdict: Who Should Pick What
Choose Kit if: You're selling digital products with meaningful price points ($100+ courses, $50+ templates), you need automation to run launches or evergreen funnels, and you're doing enough volume that the 0.5% transaction fee saves you money versus 10% alternatives. The free 10,000-subscriber plan gives you huge runway to build before paying. Once you're doing $5k+/month in product sales, Kit's combination of automation and low fees justifies the subscription cost.
Choose Beehiiv if: You're building a newsletter first, monetizing through ads or premium subscriptions, and growth mechanics matter more than course sales. The referral program and analytics are best-in-class for newsletter creators. But if you're selling one-time digital products, you're bolting on external tools and losing the integration benefits.
Choose systeme.io if: You're just starting, you need course hosting and email in one cheap platform, and you're willing to accept less polished tools to save money. Under $2k/month revenue, the all-in-one approach makes sense. Above that, you'll likely outgrow the limitations and want specialized tools.
Choose Moosend if: You're already paying for a course platform (Teachable, Podia, Gumroad) and you just need affordable email marketing. Saving $100+/month versus Kit matters to your margins, and you don't need integrated commerce because you're handling sales elsewhere.
Choose Podia if: You want one platform for everything and simplicity matters more than having the most powerful email automation. The 0% transaction fees on paid plans are competitive, and the student experience is genuinely good. You're trading email marketing power for not managing multiple tools.
Stick with free options if: You're under 1,000 subscribers and still validating your offer. Moosend's free plan (1,000 subs), systeme.io's free plan (2,000 contacts), or Kit's free plan (10,000 subs) all let you build and sell without monthly costs. Don't pay for email marketing until you're actually making money from your list.
Final Recommendation
For most creators selling courses and digital products, Kit is the right choice once you're past the validation stage and doing consistent sales. The combination of generous free tier (10,000 subscribers), powerful automation, and low transaction fees (0.5% on paid plans) creates the best math for building a sustainable creator business.
The pricing does escalate as you grow, but if you're selling products at meaningful price points, the savings on transaction fees versus alternatives like Gumroad or Substack (10%) will more than cover Kit's subscription cost. A creator doing $10k/month in course sales saves $950/month in fees by using Kit instead of a 10% platform—way more than the ~$89/month subscription at 5,000 subscribers.
Start on Kit's free plan, build your list to 10,000 subscribers while selling through Kit Commerce at the 3.5% fee, then upgrade to Creator when you're doing enough volume that the 0.5% fee saves you money. That path gives you maximum runway before paying, and scales profitably as your business grows.
If you're building a newsletter first and courses are secondary, Beehiiv's growth tools are worth considering. If you need true all-in-one simplicity on a tight budget, systeme.io works for early-stage creators. And if you're already committed to a course platform like Teachable, Moosend gives you capable email marketing for less money.
But for the specific use case of selling courses and digital products through email marketing, Kit's feature set and economics are built for exactly that—and it shows.
