Updated 2026-09-16 · Answers: “best funnel builder for digital products

How we ranked these

  • Whether the checkout, the delivery and the email sequence live in one tool
  • Transaction fees on top of the processor, because they compound on every sale
  • Course, membership or download hosting, so the buyer gets the product without a second tool
  • Cost at zero sales, since most first products earn nothing for a while
  • Order bumps, upsells and split tests for a launch that already converts
  • How much a non-technical creator sets up alone

Best free all-in-one: funnel, course, checkout and email

1. Systeme.io

A budget all-in-one funnel, email, course, and affiliate-management platform with an unusually generous free tier.

★★★★
Free plan · from $17/mo

The free plan never expires and includes 3 funnels, 2,000 contacts, 1 course, a community, a blog, unlimited emails and a checkout with no transaction fees. Startup is $17 a month for 10 funnels, 5,000 contacts and 5 courses. Templates are plain and the single free automation rule means one sequence, but nothing costs money until the product sells.

Pros
  • Cheapest paid entry point in the funnel category and a free plan that is actually usable
  • Replaces several tools (funnels, email, courses, affiliates) for solo operators
  • No transaction fees on product sales
Cons
  • Design flexibility and templates are basic compared with Webflow or ClickFunnels
  • Contact-count caps drive upgrades as a list grows
Best for a creator whose list is the business and the product is a download or a paid newsletter

2. Kit (formerly ConvertKit)

An email platform designed around individual creators, with a generous free tier and built-in ways to sell digital products and paid newsletters.

★★★★
Free plan · from $33/mo

Free to 10,000 subscribers with unlimited broadcasts, landing pages and forms, and a digital product and paid subscription checkout built into the email tool. Creator is $33 a month at 1,000 subscribers for automations and sequences. No course hosting, no order bumps, and sequences are paid-only.

Pros
  • The free tier at 10,000 subscribers is far larger than most competitors offer
  • Commerce features let a creator sell without a separate store
  • Plain-text-first email style suits personal newsletters and deliverability
Cons
  • Automations and sequences are locked entirely behind paid plans
  • Annual billing saves almost nothing (about 1.5%), so there is no incentive to commit
Best for a launch that already converts and needs order bumps, upsells and split tests

3. ClickFunnels

A premium sales-funnel builder with courses, email, and CRM features, priced for marketers who monetize aggressively.

★★★★
from $97/mo

Launch is $97 a month ($81 annual) for unlimited funnels and 10,000 contacts, with order bumps, one-click upsells, A/B testing, course and membership hosting and a built-in affiliate centre. The playbooks and templates are the reason people pay; the price at zero sales and the contact cap are the reasons to wait.

Pros
  • Purpose-built for direct-response funnels; conversion tooling is mature
  • Workspaces make it viable for agencies running several brands
  • Large training and template ecosystem around the product
Cons
  • Entry price is 5-6x Systeme.io for a similar feature set
  • Contact caps push heavy email users into higher tiers fast

A digital product is the easiest thing to sell and the easiest thing to build a mess around. The product is a file or a login; what sells it is a page, a sequence and a checkout, and what keeps the buyer is the delivery. The three tools here differ on how many of those four pieces they hold and what they charge per sale, and the right one depends on whether you are testing a first product, running a list that already buys, or scaling a launch that converts. Prices are monthly billing at the time of verification (2026-09-09).

How to choose

Decide what stage the product is at. A first product should cost nothing until it sells, and it needs the checkout and the delivery in the same place so you are not stitching tools together at midnight before a launch. A product sold to an existing list needs the email tool to own the checkout, so the buyer's tag, the sequence and the receipt all live on one record. A product that already sells needs the conversion levers: an order bump on the checkout, a one-click upsell after it, a split test on the page. Then look at the cut: a subscription is a fixed cost, a percentage per sale is a tax that grows with success. The free sales funnel guide builds the first-stage version step by step, and the funnel builder for coaches guide covers the case where the product is delivered live.

The picks in depth

Systeme.io is where a digital product should start. The free plan never expires and needs no card: 3 funnels, 2,000 contacts, 1 automation rule, 1 workflow, 1 course, 1 community, 1 blog, a custom domain, unlimited emails and a checkout with no transaction fees. That is the landing page, the opt-in, the sequence, the payment and the course delivery in one account, at $0 until the product sells and only the processor's fee when it does. Startup is $17 a month for 10 funnels, 5,000 contacts, 10 automation rules and 5 courses; Webinar at $47 adds evergreen webinars and 10,000 contacts. It also runs an affiliate program for your own product, so other people can sell it. The costs are plain templates, fewer native integrations than the specialists, and one free automation rule, which is enough for the welcome-to-offer sequence and nothing else. Choose Systeme.io for a first course, a template pack, an ebook or a membership from a creator who wants nothing to pay until it works. Skip it only when the launch needs upsells and split tests; Systeme.io vs ClickFunnels sets out that line.

Kit is the pick when the list is the business. Free covers up to 10,000 subscribers with unlimited broadcasts, landing pages and forms, and the commerce layer sells digital downloads, paid newsletters and subscriptions from a product page without a separate store. Creator is $33 a month at 1,000 subscribers for unlimited automations and sequences, A/B subject lines and branding removal; Pro is $66 for subscriber scoring, a referral system and unlimited users. The plain-text-first style suits a personal newsletter, and the Creator Network cross-recommendations grow the list. The costs are sequences locked behind the paid plan, no course hosting, no order bumps or upsells, a platform fee on each sale in addition to processing, and email design that is deliberately limited. Choose Kit if you write to people every week and the product is a download or a paid newsletter sold to that list. Skip it for a course or a launch funnel; MailerLite vs Kit covers the cheaper email alternative if commerce is not the point.

ClickFunnels is for a product that already sells. Launch is $97 a month ($81 annual) for unlimited funnels, 1 workspace, 2 team members, 10,000 contacts and 5 custom domains, with order bumps, one-click upsells and downsells, A/B split testing, course and membership hosting, email workflows and a built-in affiliate centre. The training and template ecosystem around it is the largest in the category, and for a launch with a webinar, an offer stack and an upsell path it is the tool the playbooks assume. The costs are the price at zero sales, a contact cap that a growing list passes within a year or two, and a platform that feels heavy for a single product page. Choose ClickFunnels when the product converts and the next dollar comes from the bump, the upsell and the test. Skip it while you are still finding the offer; ClickFunnels alternatives lists the cheaper routes, and ClickFunnels vs GoHighLevel covers the case where the product is a service.

What to avoid

Do not host the course in one tool, the checkout in a second and the email in a third for a first product; every handoff is a place a buyer gets lost. Do not pay a percentage per sale on a high-volume product when a $17 subscription does the same job. Do not build the upsell before the front-end offer converts; an upsell on a product nobody buys is a page nobody sees. Do not launch to strangers without a sequence; the checkout link alone works only on people who already trust you. And do not skip the refund policy and the delivery email; both are the difference between a sale and a chargeback.

When not to buy

If you have not sold the product once, sell it once by hand: a payment link and an email with the file. Buy Systeme.io's free plan the day you want the sequence and the course area, which costs nothing. Buy Kit the day the newsletter is the product. Buy ClickFunnels the month the product earns more than $97 and an order bump would earn more than that. For where the list itself comes from, the email list from zero guide is the step before this one.

Frequently asked

Do I need a funnel builder to sell a digital product, or just a checkout link?

A checkout link sells to people who already decided. A funnel sells to people who have not: a landing page that makes the case, an opt-in for the ones who leave, a sequence that brings them back, and the checkout at the end. If you have an audience that trusts you, a Kit product page or a Systeme.io checkout is enough. If you are selling to strangers, you need the sequence, and at the time of verification (2026-09-09) Systeme.io runs all of it free.

Which tool takes the smallest cut of each sale?

Systeme.io charges no transaction fees on product sales, so you pay only the processor. ClickFunnels likewise bills a subscription rather than a percentage. Kit's commerce is built for creators and takes a platform fee on each sale in addition to processing; check the current rate on its pricing page before choosing it for a high-volume product, because a percentage compounds in a way a $17 plan does not.

What does it cost to sell a $200 course to 50 people a month?

On Systeme.io, $17 a month on Startup plus processing, and the course is hosted in the same account. On ClickFunnels, $97 a month plus processing, with upsells and a split test on the checkout page. On Kit, the Creator plan for the sequence plus the commerce fee on every sale, and the course itself needs a separate host. At 50 sales a month the difference between the first two is $80 and the difference the upsell tooling makes is usually larger than that.
