Recurring software subscriptions quietly kill a lot of side projects before they ever generate a dollar. The good news: a genuinely functional business stack — landing page, lead capture, email automation and payment processing — can be built entirely on free tiers in 2026, and stay free until the business is actually making money. This guide walks through the exact stack, the free-tier limits worth knowing, and a full automated workflow you can copy today.
The core 4-part stack
Every online business, regardless of niche, needs the same four functional pieces. Everything else is optional.
| Piece | Job it does | Free tool |
|---|---|---|
| Landing page | Presents your offer and captures attention | Notion or Framer |
| Lead magnet / form | Collects an email in exchange for something free | Built into your email tool |
| Email marketing | Nurtures leads and delivers your lead magnet automatically | ConvertKit or MailerLite |
| Payment processor | Collects payment when someone's ready to buy | Stripe or Gumroad |
In plain terms
You don't need ten tools to start a digital business — you need these four, connected together. Everything else (analytics, communities, advanced automation) is worth adding later, once the core loop is already working.
Free tier breakdown, tool by tool
Landing page: Notion or Framer
Notion pages can be published publicly for free and work well for a simple, text-focused offer page. Framer's free tier gives you a genuinely designed, responsive landing page without writing any code — a better fit once visual polish starts to matter for conversion.
Email marketing: ConvertKit or MailerLite
Both offer free plans that include automation — not just a mailing list — up to a set number of subscribers (typically under 1,000). That's enough to validate an offer and build initial traction before any cost is involved.
Payments: Stripe or Gumroad
Stripe charges no monthly fee — just a small percentage per transaction, so you only pay once you're actually making sales. Gumroad works similarly and is built specifically for creators selling digital products, with delivery handled automatically.
Automation: Make.com
Make.com is the connective tissue — it's what lets a form submission automatically trigger an email, or a purchase automatically trigger delivery of a digital file, without you doing anything manually.

Read the Free Funnel GuideStep-by-step: automated PDF delivery
Here's a complete, working automation: a visitor fills out a form, and receives a digital PDF automatically, with zero manual work from you.
- Create a form in your email tool (ConvertKit or MailerLite) that collects a name and email address.
- Embed that form on your landing page (Notion or Framer).
- In your email tool, create an automated sequence triggered by "form submitted."
- Set the first email in that sequence to send immediately, with your PDF attached or linked.
- Optionally, connect Make.com to log every new subscriber into a spreadsheet automatically, so you have a simple running record without checking your email dashboard manually.
Tip: host your PDF on the email tool's own file storage rather than a personal cloud drive link — dedicated file hosting is more reliable and won't break if you reorganize folders later.
Make.com vs. Zapier free tiers
Both tools connect your apps together, but their free tiers behave differently — worth knowing before you commit workflows to one or the other.
| Make.com free tier | Zapier free tier | |
|---|---|---|
| Operations per month | 1,000 | 100 tasks |
| Multi-step workflows | Yes, on the free plan | Limited — mostly single-step "Zaps" |
| App integrations | Smaller library | Larger library of pre-built integrations |
| Best for | More complex, multi-step automations on a budget | Simple, one-off automations with popular apps |
Free tier limits change periodically — confirm current numbers on each provider's official pricing page before building critical workflows around them.
When to upgrade from free tiers
The right time to pay for a tool is when its free-tier limit is actively blocking growth you're already experiencing — not before. A useful rule: if you're regularly hitting a subscriber cap, automation limit, or page limit because real people are using your funnel, the upgrade is easily justified by the revenue it's already helping generate.
- Email tool: upgrade once you exceed the free subscriber cap with an engaged, growing list
- Automation: upgrade once you're regularly running out of monthly operations
- Landing page: upgrade once you need more pages, custom domains, or advanced design control
Common mistakes with free-tier stacks
What backfires
- Signing up for five overlapping tools "just in case"
- Building complex automations before validating the offer manually
- Ignoring free-tier limits until an automation silently stops working
- Never testing the delivery workflow as a real customer would
What works instead
- Starting with exactly the four core tools, nothing more
- Testing the offer manually before automating anything
- Checking free-tier limits monthly as your list grows
- Walking through your own funnel and automation as a customer would

Frequently asked questions
Final thoughts
None of these tools are secret — what makes this stack work is connecting them into one automated loop instead of using them as disconnected pieces. Once the loop is running, it keeps working while you sleep, and every dollar you eventually spend upgrading a tool is a dollar spent removing a limit you've already outgrown, not a bet on a business that hasn't proven itself yet.
