From 0 to 100K: how these brands used Instagram to explode their newsletter lists

In April 2024, Meta pulled the plug on its Facebook News Tab in Australia.

A month later, it stopped paying news publishers for their content.

And just like that, thousands of journalists and news creators were at risk of losing their audience overnight.

With over half a million young Australians turning to Instagram for bite-sized news, the team at The Daily Aus knew they needed a backup plan.

They started migrating their audience to their newsletter.

Fashion insiders like Leandra Medine Cohen and Laura Reilly also started their newsletter to escape Instagram’s algorithm.

Instagram can get you seen. But it can’t keep your audience.

The algorithm changes. Reach dies. One platform decision and you lose everything.

A newsletter is what keeps your audience.

And it also sells to them.

Brock Johnson, Codie Sanchez, Jasmine Starr, Ali Abdaal, Sahil Bloom - they all built 7 to 8-figure businesses off email.

If you want to monetize, build your list.

In this guide I’ll break down how to turn IG followers into 100K newsletter subscribers.

But first, let’s talk about the basics 👇

1. Pick a niche and build a community people want in

Pick a niche. Focus on one ICP.

Your Instagram should feel like it was made for them.

When people feel seen, they stay.

That’s how you build trust.

Then invite them to your newsletter for deeper conversations.

People subscribe when it feels personal. When they think, “This is so me,” they’ll want to sign-up for more.

That’s exactly what Daphne Gomez, founder of Teacher Career Coach, did. 

She built her entire brand around one problem—helping burned-out teachers leave the classroom.

As a former teacher herself, she knew the struggle of feeling stuck and not knowing what to do next.

So she picked that niche, focused on one audience, and built everything around their biggest pain point.

And that’s how she grew a newsletter with 100K+ subscribers off Instagram.

And once she had their attention, Daphne used two types of quizzes to build her email list.

2. Use Reels to acquire new attention (they’re your best growth tool)

Posts go to your followers. Stories go to superfans. Reels go wide, it’s how strangers find you. 

So if you're trying to grow and build your audience, Reels are non-negotiable. They're the most discoverable format on Instagram right now.

According to Buffer, Instagram Reels see 36% more reach than other post types

Plenty of accounts create quick Reels just by curating clips, adding subtitles, or remixing existing content.

If you don’t want a ton of time editing videos, use AI-powered tools like OpusClip or VEED make it easy to turn your tweets, blog posts, or newsletter snippets into pro-level videos.

Use them to bring people in.

Then get them on your list.

Example:

Startup Archive grew their newsletter subscribers to 40K+ by clipping startup talks and posting them.

No original filming. Just smart curation. 

All they do is keep the format simple and make it interesting for people to binge. 

Once they have their attention, they ask watchers to subscribe to their newsletter.

3. Tactics to convert attention into newsletter subscribers

→ Optimize your profile

Your bio should say who you are and what you do—in one clear sentence. Keep it simple. 

For example, “I help creators grow their audience.” Or “Daily news in 60 seconds.” 

Add a profile pic that fits your vibe.

Make it easy. 

Put your sign-up link right in your bio.

Use a short, clean URL. 

If you like, add a line that tells people why they should subscribe.

Let’s look at how Justin Welsh has optimized his bio, newsletter link, and CTA:

→ Pin a post about your newsletter

Create a simple post explaining what your newsletter is about and who it’s for. Then pin it to your profile so anyone who lands there sees it first. Think of it like your Instagram welcome mat.

Sports media brand, The Gist, encourages newsletter sign-ups by utilizing pinned posts to highlight the value of their newsletter and special moments, like hitting 1M subscribers.

→ Story Highlights

Create permanent story highlights that showcase your newsletter value

Example: 

Look at how Ali Abdaal uses Highlights to promote his newsletter

Use the last slide of every carousel post to promote your newsletter.

Structure: Value → Problem → Solution → CTA.

→ Run viral contests / giveaways to build your list

Giveaways work because people love free stuff.

You offer a prize (your product, a gift card, a bundle) — and in return, people have to do something to enter.

On Instagram, that usually means:

  • Follow your page

  • Tag a friend

  • Join your newsletter

It’s one of the fastest ways to boost your email list, grow your reach, and get real people talking about your brand.

Here’s how The Daily Aus did it:

→ Offer exclusive value through lead magnets

Give your audience something valuable for free in exchange for their email. 

Lead magnets like guides, templates, checklists, or resources provide real value to your followers, making them more likely to sign up for your newsletter.

Keep it exclusive to your newsletter to make it more attractive. 

Mandi Gubler at happyhappyhouseplant posted about her free guide that got her 800+ comments and newsletter subscribers.

→ Use automation tools like Manychat

Manychat turns IG comments into email sign-ups instantly, saving you hours of manual work.

Instead of the old "link in bio" approach, you can have followers comment specific words like "quiz" or "guide" and automate DMs with Manychat.

The tool will then automatically send DMs and collect their email on the spot.

Use it for:

  • Auto-replying to DMs.

  • Delivering lead magnets, coupons, FAQ.

  • Growing your email list

  • Set up an automated follow-up sequence.  Example: someone comments → gets a DM → clicks a link → gets a reminder if they don’t sign up.
