Match → Recommend → Grow

1

Match

Tell us about your newsletter. We find a complementary creator in your niche whose audience size is in a similar range — close enough to be fair, different enough to be valuable.

2

Recommend

You each feature the other to your audience — a Substack recommendation, a newsletter shoutout, or a dedicated cross-promo email. Whatever feels natural for your style.

3

Grow

Your partner’s readers discover your newsletter and subscribe on their own terms. You gain real, engaged subscribers who genuinely care about your topic.

Built for writers like you

Looplet is designed for independent newsletter creators who want to grow without compromising their values.

Productivity & ADHD newsletter writers

You write about systems, focus, habits, or living with ADHD. Your readers are looking for practical, no-BS advice — and so are the subscribers you’ll gain through Looplet.

Growing but stuck

You’ve got 500 to 10,000 subscribers. Organic growth has slowed. You know cross-promotion works, but finding the right partners and managing it manually is a time sink you don’t need.

Solo creators who value trust

You built your list one reader at a time. You’re not going to spam them or sell their attention to the highest bidder. You want growth that respects your audience — and theirs.

Frequently Asked Questions

What is a recommendation swap?

We match you with a complementary newsletter creator. You each feature the other — a Substack recommendation, a shoutout in your newsletter, or a dedicated cross-promo email. Your readers decide if they want to subscribe. That’s it.

Do I have to share my subscriber list?

Never. You just recommend each other’s newsletters. Your subscriber list stays 100% yours — Looplet never asks for it, never touches it, never sees it.

How do swaps work?

We match you. You each feature the other to your audience. Your readers decide if they want to subscribe to the recommended newsletter. No CSV exports, no list transfers — just genuine recommendations between complementary creators.

How do you protect my audience’s privacy?

We never access your subscriber data. Matching is based on your newsletter’s public content, niche, and approximate audience size. Your readers opt in to new newsletters on their own terms — no auto-enrollment, no data sharing.

What if I get matched with someone I don’t trust?

You always have final approval. Looplet suggests matches, but nothing happens until both writers agree. You can review their newsletter, content, and audience before committing. If it’s not a fit, just pass.

Do I need to be on Substack?

Looplet is optimized for Substack writers but works with any newsletter platform. Recommendations can take the form of Substack recs, newsletter shoutouts, or dedicated cross-promo emails.

How does matching work?

We look at your newsletter’s content, audience size, and niche to find complementary partners. The goal is newsletters similar enough that readers will care, but different enough that you’re not directly competing.

Can I cancel anytime?

Yes — no contracts, no commitments. Cancel anytime and keep access through the end of your billing period.
