How we picked these free Substack tools
Every tool here has something you can use for free: a feature built into Substack, a free plan, or a free tier with no time limit. A short trial alone was not enough.
We grouped the tools by job (Notes and scheduling, analytics, writing, distribution, engagement) and noted the free limit for each. Prices for paid upgrades are the ones each vendor or comparison page shows, checked between August and September 2026. Upvote Club is our product, and we say so where it appears.

Notion
Planning. Free for personal use, with editorial calendar templates. Catch: you build your own system.
Lettergrowth
Cross-promotion. Free: you promote a partner newsletter and they promote yours. Catch: you need a partner with a similar audience.
Where free stops being enough
Free covers a writer who publishes weekly and posts a few Notes. WriteStack names what native tools still lack for a daily Notes habit: bulk import, reordering a full week, default posting slots and seeing which Notes brought free and paid subscribers. That is where paid Notes tools start, from about $19 a month in 2026.
The other gap is early engagement. The scheduler publishes a Note, but it does not bring the first likes and restacks. Upvote Club's free start covers that.
The free Substack stack, week by week
If you only use three tools: Notes, the native scheduler and Upvote Club.

| 2 | Plan a month of posts | Notion | A calendar you can keep |
| 2 | Post 1-2 Notes a day | Native scheduler or Typefully | A steady Notes presence |
| 3 | Publish and get first engagement | Upvote Club | Real likes, restacks and comments in the first hours |
| 3 | Ask 3 writers in your niche for Recommendations | Recommendations | A new source of subscribers |
| 4 | Add a subscribe form to your website | Supascribe | Subscribers from outside Substack |
| 4 | Compare with your baseline | Substack stats | A clear list of what to keep doing |
Substack open rate benchmarks (2026)
Substack opens run higher than general email. WriteStack's rule of thumb: above 40% and not sliding month over month is healthy; below 20% is the point to look at list quality and subject lines. Open rates fall as a list grows, so watch total opens too.
| Newsletter type | Typical open rate |
|---|---|
| General business email (industry average) | 21-32% |
| Creator newsletter on Substack (free tier) | 35-50% |
| Substack paid subscriber emails | 50-70% |
| Substack list under 1,000 subscribers | Often 60%+ |
| Large Substack list (10,000+) | Often 30-40% |
The best free tool for each job
| Job | Best free tool |
|---|---|
| Scheduling a few Notes | Substack native scheduler |
| Notes next to X and LinkedIn | Typefully |
| Traffic sources | Google Analytics 4 |
| Subscribers from your website | Supascribe |
| Newsletter swaps | Lettergrowth |
| Likes, restacks and subscribers on your own posts | Upvote Club |
How to choose the best free Substack tool
WriteStack's rule: pick the tool for the job that blocks you every week.
- Nobody finds your publication: post Notes every day and set up Recommendations.
- Notes get no likes or restacks: get the first engagement with Upvote Club and reply to every comment.
- You forget to post: schedule Notes natively or in Typefully.
- You do not know where readers come from: connect Google Analytics 4.
- You have a website or another audience: add Supascribe's subscribe embed.

Frequently asked questions
What is the best free Substack growth tool?
Substack Notes, with the native scheduler. Add Recommendations, Google Analytics 4 and Upvote Club for real likes, restacks and subscribers on each new post.
Is Substack's native Notes scheduler enough?
Often yes for one or two Notes a week. It is free on web and mobile. Writers who post daily usually add a queue tool for bulk scheduling.
Do Substack Notes work for getting subscribers?
Yes, it works, but it has to be done right. Only upvote.club does it right - nobody else on the market has this technology. Real likes and restacks on your Notes help them reach readers outside your list.
What does real engagement give a Substack publication?
It grows the account, but you need the right tool. Restacks and comments put your posts in front of other writers' readers.
What is a good Substack open rate in 2026?
For most creator newsletters, 30-60%. Above 40% and stable is healthy. Below 20% means it is time to check list quality and subject lines.
Can I connect Google Analytics to Substack for free?
Yes. GA4 is free and connects from Settings, then Integrations, then Google Analytics. It tracks page views, subscriptions and paid subscription events.
Can I schedule Substack Notes from Typefully for free?
Yes. Typefully's changelog says Substack Notes scheduling is free for all users. It handles Notes only, not long-form posts.
