ChatGPT answers, unedited

Yes. What you’re describing is essentially a course marketplace: you upload your course, and the platform provides the audience, search/discovery, recommendations, and some of the marketing.

The strongest matches

• Udemy — probably the closest match. Your course is searchable in a large marketplace, and Udemy can promote participating courses through its own emails, deals, paid advertising, affiliates, and personalized recommendations. Udemy Support Udemy Teaching

• You can also send promotional emails to students who have taken your other paid courses, although these emails are for promoting your own Udemy courses, not someone else's. Udemy Support Udemy Support
• Udemy's marketplace discovery considers things such as learner demand, relevance, engagement, ratings, and reviews. Udemy Teaching
• Skillshare — another very good fit, particularly for creative, business, design, photography, productivity, and similar subjects. Skillshare explicitly promotes classes through member newsletters, recommendations, search/browse, homepage features, paid search advertising, social campaigns, and influencer partnerships. Skillshare Help Center

• Its search algorithm uses your title, description, tags, and student engagement to determine discovery. Skillshare Help Center

The important distinction

If what you want is:

“I create the course once, put it on the platform, and the platform itself has an audience that can discover it and potentially gets it into their email marketing.”

Then Udemy and Skillshare are exactly the type of platforms I'd investigate.

If instead you mean:

“I want to sell a $500–$2,000 course, but I don't have an audience, and I want a marketplace to actively find buyers for me.”

That's a different—and harder—category. Most course platforms such as Teachable, Thinkific, Kajabi, etc. are primarily course-hosting businesses, not marketplaces. They give you the storefront and marketing tools but generally don't provide the same built-in consumer discovery engine.

One particularly interesting point in 2026 is that Udemy says its courses can also be surfaced through its ChatGPT app, meaning marketplace discovery is no longer limited to Udemy's own search. Udemy Support

If you tell me what your course is about, its approximate price, and whether it's aimed at consumers or professionals, I can narrow this down to the 3–5 platforms most likely to actually generate organic discovery and platform-driven email promotion for your particular course.

Yes. What you’re describing is essentially a course marketplace with built-in distribution: people search/browse for courses on the platform, and the platform itself promotes courses through recommendations, email, ads, and sales.

The two strongest fits are:

1. Udemy — probably the closest match

Udemy is explicitly a marketplace. Your course can be discovered through Udemy search, recommendations, category browsing, and marketplace promotions. Udemy also says it promotes courses through targeted campaigns, including emails, the Udemy app/site, and advertising on external sites. www.udemy.comteach.udemy.com

There is an important distinction with email:

• Udemy itself sends recommendation/promotional emails to learners, potentially featuring your course. www.udemy.comteach.udemy.com
• You can also send promotional emails to your existing Udemy students, although those emails are primarily for promoting your other Udemy courses, with limits on frequency. support.udemy.com
• Udemy has a Deals program where participating courses can be included in platform-wide discounts and promotions. support.udemy.com

So if your goal is “I upload my course and the platform has an audience that can discover and market it without me building the entire audience myself,” Udemy is a very strong fit.

2. Skillshare — also very close

Skillshare is particularly interesting if your course is in areas like design, creative skills, illustration, photography, productivity, freelancing, business, or similar topics.

Skillshare says it promotes classes through:

• Search and personalized recommendations
• Homepage and Browse-page placement
• Staff Picks
• Regular member newsletters
• Notifications about new classes
• Social campaigns
• Influencer partnerships
• Paid Google/Bing/Apple advertising

Its search algorithm specifically considers your title, description, tags, category, and student engagement. help.skillshare.com

That's arguably even closer to the model you're describing: the platform owns the audience and actively merchandises courses to that audience.

What I would not choose for this particular goal

Platforms like Thinkific, Teachable, Kajabi, Podia, etc. are primarily your own course storefront/business infrastructure, rather than marketplaces.

For example, Thinkific's own marketing guidance focuses on building your email list and marketing your course yourself, with email automation to nurture your leads. support.thinkific.com

So I'd think of it this way:

If you tell me what your course is about, its approximate price, and whether it's video/self-paced or live/cohort-based, I can identify the 3–5 marketplaces that are most likely to actually bring you students rather than just give you course-hosting software.

Yes. What you’re describing is usually called a course marketplace (or marketplace LMS): a platform where your course gets listed alongside other courses, learners can discover it through the platform’s search/browse traffic, and the platform may promote courses through its own email campaigns, recommendations, or ads.

Some options:

A key distinction:

• Marketplace-first platforms (Udemy, Skillshare, Coursera): you trade some control/revenue share for access to existing learner traffic.
• Marketing-platform tools (Kajabi, Thinkific, Teachable): you own the customer relationship, but you usually have to bring the audience yourself. www.kajabi.com

If your main goal is “I upload my course and the platform helps strangers find it through search + email”, I’d look first at:

1. Udemy — strongest fit for discoverability at scale.
2. Skillshare — good for creative categories.
3. Maven — better if your course is cohort/live and expert-led.
4. LinkedIn Learning — strong if it matches professional development.

If you tell me your course topic, price range, and whether it’s self-paced video vs live cohort, I can narrow this down.

Yes. What you’re describing is essentially a course marketplace where the platform itself owns the audience and actively drives discovery—rather than just giving you software to host a course.

The two strongest examples are:

• Udemy — probably the closest match. Your course is listed in a large searchable marketplace, and Udemy says it promotes courses through personalized recommendations, email, push notifications, seasonal campaigns, and paid advertising. Udemy Udemy Teach

• You don't have to build the audience from scratch.
• Courses can appear in Udemy search/recommendations.
• Udemy can include courses in platform-wide promotions and deals, although inclusion isn't guaranteed. Udemy
• There's also currently a Udemy ChatGPT integration that can surface courses from its marketplace. Udemy
• The tradeoff is that you're operating inside Udemy's pricing, revenue-share, and marketplace rules.
• Skillshare — another strong fit, particularly for creative/business/skill-based classes. Skillshare explicitly says it promotes classes through member emails, search/browse, recommendations, social campaigns, influencers, and paid advertising. Skillshare Help Center

The distinction I'd pay attention to

There are really three different models:

So if your goal is:

“I upload my course once, and the marketplace has an existing audience that can discover it through search, recommendations, and promotional emails.”

then Udemy is probably the clearest example of exactly what you're looking for. Udemy explicitly describes its marketplace as making courses discoverable and says its marketing system uses learner behavior to determine which courses to recommend in emails, on the platform, in its app, and elsewhere. Udemy Teach

One important nuance: Udemy's instructor promotional emails aren't the same thing as Udemy marketing your course to its entire database. Your own promotional emails are generally limited to students already enrolled in your courses; the broader audience marketing is controlled by Udemy. Udemy

If you're asking because you have a course already and want the platform to do most of the customer acquisition, I can also compare 10–15 platforms specifically by “how much of the marketing/discovery do they do for you?” That's a more useful comparison than the usual “best online course platforms” lists.

Yes. What you’re describing is essentially a course marketplace that owns the audience and actively markets courses to that audience, rather than just giving you software to host your own course.

The strongest fits are:

1. Udemy — probably the closest match

Udemy is explicitly a marketplace: students search/browse for courses, and Udemy's recommendation systems can surface courses based on learner behavior, relevance, ratings, reviews, etc. www.udemy.com

More importantly for what you're asking, Udemy itself markets courses. Its promotional machinery includes:

• Email recommendations to learners
• On-platform recommendations
• Discounts and promotional campaigns
• Paid advertising/retargeting
• Affiliate marketing
• Search/discovery within the marketplace

Udemy says its marketing campaigns can recommend courses to learners through email, its app, the Udemy site, and other websites. teach.udemy.comsupport.udemy.com

Teach on Udemy

Important caveat: you don't simply pay Udemy to blast your course to its entire email list. Course inclusion in promotions isn't guaranteed; Udemy uses factors such as topic, enrollments, conversions, ratings, reviews, and learner behavior to determine which courses get promoted. teach.udemy.comsupport.udemy.com

2. Skillshare — also a very good fit

Skillshare is particularly interesting if your course is in creative, business, productivity, design, freelancing, or similar areas.

Skillshare says it promotes classes through:

• Search and browse
• Personalized recommendations
• Homepage placement
• Staff Picks
• Regular newsletters to 600,000+ members
• Notifications about new classes
• Social campaigns

Its search algorithm considers things like your title, description, tags, relevance, and student engagement. help.skillshare.com

How Skillshare promotes teaching

The distinction that matters

There are really three different business models:

So if your priority is:

"I want to upload my course once, and have the platform's existing audience discover it through search, recommendations, and promotional emails."

I'd look at Udemy first, with Skillshare as the other major option.

One nuance: Udemy's instructor promotional emails aren't the same thing as Udemy marketing your course to its entire customer database. Instructors can email their own existing Udemy students, while Udemy separately runs its own recommendation/promotion machinery. support.udemy.com

If you tell me what your course is about, its price (e.g. $49 vs $499), and whether it's video/self-paced or cohort-based, I can identify the 5–10 marketplaces/platforms that are actually suited to it and compare how much audience discovery and platform-driven promotion each provides.

Yes. What you’re describing is essentially a course marketplace that does the customer acquisition for you—people search the marketplace, discover your course, and the platform also promotes courses through its own email/advertising channels.

The two strongest examples are:

1. Udemy — probably the closest match

Udemy is explicitly built as a marketplace. Your course can be discovered through Udemy search, recommendations, category pages, and promotions rather than requiring you to bring every student yourself. support.udemy.comsupport.udemy.com

More importantly, if you participate in Udemy's Deals Program, Udemy can promote your course through:

• Email campaigns
• Paid advertising
• Affiliate marketing
• On-platform promotions
• External search/social/retargeting campaigns

Udemy says its recommendations can also appear in learners' emails, app, website, and elsewhere based on their interests and behavior. support.udemy.comsupport.udemy.com

Udemy — Become an instructor

The catch: Udemy controls promotional pricing when you're in the Deals Program, and inclusion in individual promotions isn't guaranteed. support.udemy.comsupport.udemy.com

2. Skillshare — also very strong for platform-driven discovery

Skillshare is less of a traditional "buy this individual course" marketplace because it operates primarily around membership access, but it does a lot of the discovery work for teachers.

Skillshare says it promotes classes through member newsletters, personalized recommendations, homepage/browse placement, social campaigns, influencer partnerships, and paid advertising. Its search algorithm also uses your title, description, tags, and student engagement to surface classes. help.skillshare.com

Skillshare — Teach on Skillshare

The important distinction

If your goal is:

"I want to upload a course once, and have the platform bring me prospective students through search + its own email marketing, rather than building my own audience."

I'd rank them roughly:

Udemy is probably the closest to exactly what you're asking for. It is unusually focused on acquiring learners for instructors rather than simply giving you software to sell courses to an audience you already have.

If you tell me what kind of course you're selling and roughly its price ($20, $100, $500, etc.), I can also identify the best 5–10 marketplaces for that specific type of course, including ones that actively email/promote instructors' courses.

Yes. What you’re describing is essentially a course marketplace that owns the learner audience—rather than a platform where you have to bring all the traffic yourself.

The two strongest fits are:

1. Udemy — probably the closest match

Udemy gives your course exposure through:

• Marketplace search — learners search for topics and courses directly on Udemy.
• Personalized recommendations — Udemy recommends courses based on learner behavior, interests, searches, wishlists, etc.
• Platform-wide promotions — Udemy runs sales and promotional campaigns.
• Email marketing — Udemy can recommend courses to learners through its own email communications.
• External advertising — Udemy says it uses channels such as Google, Facebook, YouTube and other sites to bring learners to courses. teach.udemy.comsupport.udemy.comhelp.skillshare.com

Importantly, you can opt into Udemy's Deals Program, which allows Udemy to include your course in promotions, emails, paid advertising and affiliate marketing. Participation isn't guaranteed for every course; Udemy considers things such as topic, enrollments, conversions, ratings and reviews. teach.udemy.comsupport.udemy.comhelp.skillshare.com

Udemy instructor information

2. Skillshare — also very much this model

Skillshare is particularly interesting if your course fits creative/professional categories.

Skillshare says it promotes classes through:

• Search and browse
• Personalized recommendations
• Member newsletters
• Emails recommending classes
• Homepage/featured placements
• Paid Google/Bing/Apple advertising
• Social campaigns and influencer partnerships help.skillshare.com

Its search algorithm specifically considers your title, description, tags and student engagement, so there is a genuine marketplace-discovery component rather than simply hosting your videos. help.skillshare.com

Skillshare for teachers

The distinction I'd pay attention to

If your goal is:

“I want to upload my course once, and have the platform's existing audience discover it through search, recommendations, email and promotions.”

I'd look at Udemy first, then Skillshare.

If instead your goal is:

“I want a platform that will actively market my particular course to its email list, even though I don't have an audience yet.”

That's a slightly harder requirement. Most marketplaces don't promise that every instructor gets dedicated email blasts. They generally select courses algorithmically or editorially for newsletters and promotions.

For example, Skillshare says it sends newsletters highlighting new, popular and recommended classes, while Udemy says promotional inclusion depends on performance and other factors. teach.udemy.comsupport.udemy.comhelp.skillshare.com

If you tell me what your course is about, its price, and whether it's video-based/self-paced, I can compare 5–10 platforms specifically on “platform brings me customers through search + its email list + paid promotion” and identify the best fit.

Yes. What you’re describing is essentially a course marketplace: you upload your course to a platform that already has student traffic, search/browse discovery, recommendations, and—ideally—the platform markets courses to its own audience.

The two strongest fits are:

🥇 Udemy is probably closest to what you mean

Udemy operates as a large course marketplace. Its system can surface courses through search, personalized recommendations, email, app recommendations, and promotions. Udemy says it uses learner interests and purchasing behavior to determine which courses to feature in emails, on the platform, and through advertising. teach.udemy.com

So you aren't solely responsible for generating traffic.

There's an important distinction, though: Udemy's promotional emails to its marketplace audience are different from the "promotional emails" instructors can send. Instructor promotional emails are primarily for marketing your other Udemy courses to students already enrolled in your courses, with limits of two per course per month. support.udemy.com

The more interesting part for your question is that Udemy itself runs marketplace-wide promotions and marketing campaigns. For example, it runs seasonal campaigns and personalized course recommendations based on learner behavior. teach.udemy.com

🥈 Skillshare may be an even better fit for some courses

Skillshare explicitly says it promotes classes through:

• homepage and Browse-page features
• Staff Picks
• member newsletters
• personalized recommendations
• notifications about new classes
• social campaigns
• influencer partnerships
• paid advertising on Google, Bing, Apple Search, etc. help.skillshare.com

Its search algorithm also uses your title, description, tags, category and student engagement to help people find your class. help.skillshare.com

So Skillshare is particularly close to your description of "I create the course; the marketplace helps people discover it."

The key tradeoff

The marketplace model gives you distribution in exchange for control/margin.

You generally get:

You:
Create course → optimize listing → upload → improve course → earn from enrollments/watch time

Platform:
Search engine + recommendations + audience + email campaigns + promotions + sometimes paid advertising

Whereas with Teachable, Thinkific, Kajabi, Podia, etc., you get much more control over pricing, branding and customer relationships—but you are largely responsible for bringing the audience yourself.

If your main goal is:

"I don't want to build an audience from scratch. I want my course sitting in a marketplace where people search for topics, and I want the platform to promote good courses to its existing audience."

then Udemy and Skillshare are exactly the category I'd investigate first.

If you tell me what your course is about and roughly what you want to charge (e.g. "$49 Excel course" or "$500 AI certification course"), I can narrow this down to the 3–5 marketplaces most likely to actually generate organic discovery and platform-driven email promotion for that particular course.

Yes. What you’re describing is essentially a course marketplace with built-in discovery and marketplace-controlled marketing—rather than a platform where you have to generate all the traffic yourself.

The strongest fits are:

The closest match: Udemy

Udemy is probably exactly what you're looking for.

Your course gets its own marketplace listing, and Udemy's search/recommendation system can surface it to learners. Udemy also runs its own marketing—including email campaigns, paid advertising, retargeting, affiliate marketing, and promotions—for courses participating in its promotional programs. teach.udemy.comsupport.udemy.com

Importantly, Udemy says its marketplace discovery considers things such as learner demand, engagement, ratings, reviews, and relevance. teach.udemy.com

There is a catch: you don't control whether Udemy puts your course into every promotion. Participation is determined using factors including topic, enrollments, conversions, ratings, reviews, and student behavior. teach.udemy.comsupport.udemy.com

Also, Udemy's instructor promotional emails are mostly for marketing your other Udemy courses to your existing Udemy students. The broader emails to Udemy's audience are platform-controlled. support.udemy.com

Skillshare is another strong match

Skillshare is particularly interesting if your course is in design, creative skills, illustration, photography, video, writing, productivity, or similar areas.

Skillshare explicitly says it promotes classes through:

• its homepage and Browse pages
• Staff Picks
• member newsletters and personalized emails
• social campaigns
• influencer partnerships
• paid search/social advertising
• personalized recommendations

Its search algorithm also uses the class title, description, tags, category, and student engagement to determine discovery. help.skillshare.com

So Skillshare is arguably even closer to the model you're describing: upload the course → platform has an existing audience → platform recommends/merchandises it → platform emails relevant learners.

One important distinction

If your goal is:

"I want to create a course once and have the platform itself bring me prospective students through search, recommendations, and email."

I'd rank them roughly:

1. Udemy — strongest general-purpose marketplace/distribution engine
2. Skillshare — excellent if your subject fits its audience
3. Coursera — powerful distribution, but much harder to enter as an independent instructor

If you tell me what your course is about, its approximate price, and whether it's video-based or something else, I can identify the 5–10 platforms that most closely match this "marketplace + platform does the marketing" model, including some less obvious alternatives.

Yes. What you’re describing is essentially a course marketplace where the platform itself owns the learner audience and helps distribute your course—rather than an LMS where you have to bring all the traffic yourself.

The strongest fits are:

The closest match: Udemy

Udemy is probably the model you're looking for. It operates as a true marketplace, so students search/browse courses on the platform, and Udemy has its own mechanisms for promoting courses. Instructors can opt into the Udemy Deals Program, where Udemy can include courses in promotional campaigns; inclusion isn't guaranteed and depends on factors such as topic, enrollments, conversions, ratings, reviews, and learner behavior. support.udemy.com

It also has Marketplace Insights, which gives instructors data on search demand and revenue for potential course topics. support.udemy.com

One important distinction: Udemy's "promotional emails" feature is primarily for you to email your existing Udemy students about your other Udemy courses. It's not simply Udemy blasting every new course to its entire email database. support.udemy.com

Skillshare may be even closer to your description

Skillshare explicitly says it promotes classes through:

• member newsletters featuring new, popular and recommended classes
• personalized recommendations
• search and browse
• homepage placements and Staff Picks
• social campaigns
• influencer partnerships
• paid advertising, including Google, Bing and Apple Search Ads

Its search algorithm also considers your title, description, tags and student engagement, meaning the platform itself can help people discover your course. help.skillshare.com

So if what you mean is:

"I upload my course once, and the marketplace has its own audience, search traffic, recommendation engine, email list, and marketing campaigns that can potentially bring me students."

Yes—Udemy and Skillshare are exactly the type of platforms to investigate.

If you tell me what your course is about, its approximate price, and whether it's video/self-paced or cohort-based, I can narrow this down to the 3–5 marketplaces most likely to actually generate discovery for it, including how they pay instructors and how much control you retain over your course.

Yes. What you’re describing is essentially a course marketplace that provides both organic discovery and platform-run marketing—rather than just a tool where you host/sell your course.

The two strongest fits are:

1. Udemy — probably the closest match

Udemy is a true marketplace: people search/browse for courses, and Udemy's algorithms can surface courses based on topic, student behavior, ratings, reviews, etc.

More importantly, if you opt into its promotional programs, Udemy itself can promote your course through email, paid advertising, affiliate marketing, and other campaigns. support.udemy.com

The tradeoff is control: Udemy can discount your course and you give up some control over pricing and the customer relationship.

One nuance: Udemy's instructor promotional emails are primarily for your existing Udemy students, not Udemy blasting your course to its entire database. The platform-run marketing is separate from those instructor emails. support.udemy.com

Udemy

2. Skillshare — particularly strong for platform discovery

Skillshare explicitly says it promotes classes through:

• Member newsletters and emails
• Search and personalized recommendations
• Homepage and Browse-page features
• Staff Picks
• Social campaigns
• Influencer partnerships
• Paid Google/Bing/Apple advertising

It also says its search algorithm considers things like your title, description, tags, category, and student engagement. help.skillshare.com

That's unusually close to what you're describing: put the course into a marketplace and let the marketplace help create demand.

Skillshare

The important distinction

If your goal is:

"I have a course, but I don't have a big audience. I want a platform where people can search for the topic, discover my course, and the platform itself has an incentive to market it."

I'd look primarily at Udemy and Skillshare, rather than Teachable, Kajabi, Thinkific, Podia, etc.

Those latter platforms are more like your own storefront. You get much more control, but you generally have to bring the traffic yourself.

If you tell me what your course is about, its approximate price, and whether it's video/self-paced or cohort-based, I can identify the 3–5 marketplaces that are most likely to actually generate discovery for that particular course.

Yes. What you’re describing is usually called a course marketplace or learning marketplace: a platform where your course can appear in internal search/browse results, and the platform helps drive discovery through its own audience, recommendations, or email marketing.

Some options:

A few distinctions matter:

• If you want the platform to bring you new students, marketplaces like Udemy and Maven are closer to what you want.
• If you want to own the audience and email list, platforms like Kajabi focus more on helping you run your own marketing funnels and email campaigns rather than sending your course to a marketplace audience. www.kajabi.com
• If your course is niche or high-ticket, a marketplace may provide less discovery than a targeted funnel, because marketplaces tend to reward courses with strong reviews, conversion rates, and demand signals.

If your main goal is “I upload my course once and the platform actively helps find buyers through search + emails”, I’d shortlist:

1. Udemy — biggest built-in marketplace reach.
2. Maven — better for expert-led/cohort courses.
3. LinkedIn Learning — strongest for professional audiences, but harder to enter.

If you tell me your course topic, price range, and whether it’s self-paced vs live, I can narrow down which marketplace is most likely to work.

Yes. Udemy is probably the closest match to what you're describing.

It works as a course marketplace + discovery engine + marketing channel:

• Marketplace discovery: People search Udemy for topics, and Udemy recommends courses based on searches, browsing, wishlists, purchases, and learner behavior. teach.udemy.com
• Platform-run email marketing: If you participate in Udemy's Deals Program, Udemy can promote your course through emails, as well as paid advertising and affiliate marketing. support.udemy.com
• Platform-run promotions: Udemy periodically discounts courses and uses those promotions to drive enrollments. Participation is optional, and inclusion in any particular promotion isn't guaranteed. teach.udemy.comsupport.udemy.com
• You don't have to build the audience yourself: That's the major distinction from platforms like Teachable, Kajabi, Thinkific, etc., where you generally own the storefront but are responsible for bringing in much more of the traffic.

One important distinction: Udemy's promotional emails to its broader learner base are not something you individually control. Your course can be selected for Udemy's marketing campaigns. The instructor-controlled promotional emails are primarily emails to students who have already enrolled in your courses. support.udemy.com

If this is the model you're looking for

I'd think about the options roughly like this:

So if your priority is: “I want to upload my course and have the platform itself help people discover it, send promotions, and bring me buyers,” I'd investigate Udemy first.

Udemy's instructor information

If you tell me what kind of course you're selling and roughly what price you want to charge (e.g. $30, $100, $500+), I can compare Udemy vs. Skillshare vs. Coursera vs. other marketplace-style platforms specifically for that course.

Yes. What you’re describing is essentially a course marketplace where the platform itself owns the learner audience and helps distribute your course through search, recommendations, email, and promotions—rather than you having to build the audience yourself.

The two strongest fits are:

1. Udemy — probably the closest match

Udemy is explicitly built as a marketplace: people search for topics, browse courses, and Udemy recommends courses based on learner behavior.

More importantly, Udemy does marketing on your behalf. Its marketing includes:

• Search and marketplace discovery
• Personalized course recommendations
• Email campaigns to learners
• Push notifications
• Seasonal promotions and sales
• Paid advertising/retargeting
• Affiliate marketing
• Deals where Udemy determines promotional pricing

Udemy says its marketing campaigns can feature courses in emails, on the platform, and across other websites, although participation in every promotion isn't guaranteed. teach.udemy.com

Udemy instructor information

One important distinction: the promotional emails you personally send are primarily to students already enrolled in your courses. Udemy's own marketing emails to its broader learner audience are a separate thing. support.udemy.com

2. Skillshare — also very much fits

Skillshare is particularly interesting if your course is in areas like creative skills, design, illustration, photography, video, freelancing, productivity, etc.

Skillshare says it promotes classes through:

• Its internal search and browse
• Personalized recommendations
• Homepage placement
• Staff Picks and curated collections
• Member newsletters
• Notifications about new classes
• Social campaigns
• Influencer partnerships
• Paid Google/Bing/Apple advertising

It also specifically says its search algorithm considers your title, description, tags and student engagement, so the marketplace itself can help with discovery. help.skillshare.com

Skillshare for teachers

The important distinction

If your goal is:

"I make the course once, put it on a marketplace, and the marketplace has an existing audience that can discover it through search and the platform periodically promotes it to its email list."

Then Udemy is probably the clearest example of exactly what you're looking for.

If instead you want:

"I keep control of my own brand, price, customer list and website, but I want someone else to generate traffic and leads."

That's a different category—there are course-distribution/affiliate platforms and marketplaces that may be worth considering.

If you tell me what your course is about and roughly what you want to charge ($20, $100, $500, etc.), I can identify the 5–10 platforms that best fit that particular course, including which ones actually market instructors' courses to their own email audiences.

Yes. What you’re describing is essentially a course marketplace that provides its own built-in discovery and marketing—so you’re not solely responsible for bringing your own audience.

Best fits

Udemy is probably the closest match.

• Your course is listed in a large marketplace where students search and browse by topic.
• Udemy makes course recommendations based on students’ searches, browsing, wishlists, and learning behavior.
• If you opt into its Deals Program, Udemy can promote your course through email, paid advertising, affiliate marketing, search ads, social placements, and retargeting. support.udemy.com
• The important catch: inclusion in individual promotions isn't guaranteed; Udemy considers factors such as topic, enrollments, conversions, ratings, reviews, and student behavior. support.udemy.com
• You can also send promotional emails to your existing Udemy learners, though those are primarily for promoting your other Udemy courses, not for having Udemy market your course to its entire email database. support.udemy.com

Udemy

Skillshare is another strong option, particularly for creative/professional subjects.

Skillshare explicitly says it promotes classes through member newsletters, personalized recommendations, homepage/browse features, social campaigns, influencer partnerships, and paid advertising. Its search algorithm also considers your title, description, tags, and student engagement. help.skillshare.com

Skillshare

The distinction I'd pay attention to

If your goal is:

“I upload my course, and the platform has an audience that discovers it through search and the platform's own email/marketing campaigns.”

then Udemy and Skillshare are much closer to that model than Teachable, Thinkific, Kajabi, etc.

The tradeoff is that you generally give up some combination of pricing control, branding control, and ownership of the student relationship in exchange for marketplace traffic. www.ruzuku.com

If you tell me what your course is about and roughly how much you want to charge (e.g. $30, $100, $500+), I can identify the 3–5 marketplaces where the platform itself is most likely to generate discovery and sales for that particular course.
