Hey, Grow Newsie reader!

2025 has been a transformative year for newsletters. The strategies that worked in 2023 are no longer cutting it, and creators who've cracked the code are seeing explosive growth while others plateau.

I've spent the past few weeks analyzing what the fastest-growing newsletters did differently this year, and the patterns are clear. Here are the biggest newsletter growth tips for 2026 that actually will move the needle.

The biggest shift? Co-registration tools like SparkLoop, beehiiv Boosts, and After Offers exploded in popularity. Top creators report this is now their most reliable acquisition channel as advertising costs continue to climb.

Why it works: When someone subscribes to Newsletter A, they immediately see an offer to subscribe to Newsletter B. Since they're already in "signup mode," conversion rates are significantly higher than cold traffic.

Real numbers: Creators are earning between $0.50 to $3.00 per referred subscriber while simultaneously growing their own lists. It's the rare win-win in newsletter growth.

Action step: If you're not using co-registration yet, you're leaving subscribers (and revenue) on the table.

Data from HubSpot's 2025 State of Newsletters Report confirms what top creators already knew: newsletters featuring personal opinions, tips, and hot takes generate the highest open rates, click rates, and conversion rates.

The boring, corporate-style newsletters? They're dying. Readers want personality, unique perspectives, and content that feels like it's coming from a real person, not a brand.

Your takeaway: Stop trying to sound "professional." Write like you're emailing a friend who shares your interests.

According to research, 42% of newsletter pros rank direct recommendations from current subscribers as their most effective growth strategy. This beat out paid ads, social media, and every other channel.

The creators who cracked this code did three things:

Remember: One engaged subscriber who forwards your newsletter is worth more than 100 passive subscribers.

28% of creators now use AI for brainstorming and 25% for content creation, with early adopters reporting they're saving 1-3 hours per week. But here's the critical insight: AI is being used for speed, not replacement.

The winning formula is AI for drafts and outlines, human editing for voice and personality. Creators who went full-AI saw their engagement rates drop because readers can spot generic content.

The uncomfortable truth from 2025: organic growth alone isn't enough anymore. Social media algorithms changed, AI overviews reduced Google click-through rates, and the free traffic sources dried up.

Newsletters that scaled this year invested in:

Budget allocation matters: The fastest-growing creators spent 15-20% of their revenue on subscriber acquisition.

Guest posting in other newsletters, creator collaborations, and newsletter swaps generated thousands of subscribers for creators who executed well.

The key insight? Don't collaborate with the biggest newsletters in your niche. Target newsletters that are similar in size to yours. You'll have a higher acceptance rate and more equitable value exchange.

One creator grew from 0 to 18,000 subscribers in a year primarily through strategic collaborations with other newsletter operators.

Multiple creators reported that LinkedIn became their primary growth channel in 2025. Why? The platform's algorithm still favors genuine engagement, and the professional audience matches newsletter demographics perfectly.

Winning tactics included:

Result: Each post now drives 150+ new subscribers for established creators.

Here's a shocking stat: 23% of creators using zero personalization reported making $0 per month, while 43% earned between $1-100 monthly. Meanwhile, creators who personalized based on subscriber demographics saw significantly higher revenue.

The message is clear: Segment your list, personalize content, and give subscribers options to choose their preferences. Generic newsletters don't cut it anymore.

The least sexy but most important lesson? Creators who committed to a consistent publishing schedule (weekly, bi-weekly, or daily) saw better growth than those who posted irregularly, regardless of content quality.

Your audience needs to know when to expect you. Consistency builds trust, trust builds loyalty, and loyalty builds word-of-mouth growth.

If you're struggling to grow your newsletter, the solution isn't to work harder—it's to work smarter. The creators winning this year are:

The newsletter space is more competitive than ever, but the opportunities are also bigger. Pick 2-3 strategies from this list, commit to them for 90 days, and track your results ruthlessly.

Growth in 2026 won’t be about luck—it will be about applying proven strategies with discipline.

Keep growing!

With love,
