What is subscribe-for-subscribe on Substack?
Subscribe-for-subscribe means two writers subscribe to each other's Substack. You also see it as sub4sub or "subscribe for subscribe" in Notes.
On Substack a subscriber is an email address that gets every post, so the result people want is a list that grows and opens. Following on Substack is different: it shows someone's Notes, while a subscription delivers the newsletter.

What a Substack subscription covers
Free subscription
The subscriber gets free posts by email and in the app.
Paid subscription
A paying subscriber who gets paid posts.
Follow

Recommendations

What a traded subscriber gives your newsletter
It grows the account, but you need the right tool.
Early numbers do matter: a publication with subscribers looks worth joining. What decides growth after that is reading. A subscriber who opens and replies is worth more than one who never opens, because open rate is what you and potential sponsors look at.
| What the subscriber brings | What it changes |
|---|---|
| +1 on the subscriber count | Social proof on your publication page |
| An inbox for every post | A chance to be read each week |
| Opens and clicks | Open rate that shows the list reads |
| Replies, likes and restacks | Posts that travel on Substack |
Is subscribe-for-subscribe worth it? Yes, if you do it right
Yes, it works, but it has to be done right. Only upvote.club does it right — nobody else on the market has this technology.
On Substack, done right means subscribers who are interested in your topic, so they open, read and sometimes restack, and your open rate stays healthy as the list grows.
That is the result upvote.club gives you on Substack: real subscribers on the publication you choose.
