Newsletter Growth Strategy: 30 Tactics to Reach 10K Subscribers

To grow a newsletter, pick a narrow audience and a clear promise, and make subscribing easy everywhere you already reach people (your website, product, social profiles and customer list). Then borrow other audiences through recommendations, guest posts, cross-promotions and partners, turn readers into recruiters with referrals, and keep them by sending useful issues on a fixed schedule. Add paid acquisition only once you can see which source brings readers who stay and click.

For a B2B SaaS company, a newsletter drives sales when each issue teaches something your buyers need and ends with one next step, such as a trial, a demo or an email course. Below are the five steps, which tactics fit your list size, 30 tactics, and how to tie the list to pipeline.

Key Takeaways

• New newsletters on beehiiv reached a median of 482 subscribers in their first month, and median subscriber counts reached 8,314 by the end of year one, in beehiiv’s State of Newsletters 2026 (2025 platform data).
• Newsletters in beehiiv’s Recommendation network grew 2.75x faster on average (beehiiv, 2026), and Substack said in February 2024 that recommendations and its app drove 50% of all new subscriptions on its platform.
• 54% of B2B marketers named email newsletters one of their most effective thought leadership channels, second only to LinkedIn at 76%, in CMI and MarketingProfs’ survey of 1,015 B2B marketers for 2026.
• Average open rates were 41.24% on beehiiv in 2025 and 35.63% across all Mailchimp users (data as of December 2023), but Apple Mail Privacy Protection inflates opens, so clicks, replies and sign-ups are better growth signals.

How to Grow a Newsletter in 5 Steps

1. Pick one reader and one promise. Name the job title you write for, what each issue gives them and how often it arrives. A newsletter for SaaS CFOs about metrics is easier to grow than one about business in general, because readers can tell at a glance that it’s for them.
2. Make subscribing easy where you already have attention. Put a signup form on your best blog posts, in your product, on your social profiles and in your email signature, and tell your existing customers once.
3. Borrow other audiences. Recommendations, guest posts in other newsletters, cross-promotions and co-marketing put you in front of people who already read newsletters in your niche.
4. Turn readers into recruiters. Make each issue easy to forward, ask your most engaged readers to share it, and add a referral reward once the list is big enough for it to matter.
5. Keep readers and measure each source. Send on a fixed schedule, watch unsubscribes next to sign-ups, and track which sources bring readers who click. Put more time into those and drop the rest.

Your customer list gives a newsletter a fast start, but it isn’t a growth engine on its own. Casey Hill, a senior growth marketing manager at ActiveCampaign, told Nathan Latka in July 2024 that the company had launched a newsletter called SaaS Steps, profiling the growth of companies such as ActiveCampaign, Typeform and Thinkific, and cross-promoted it to its full list of 800,000 to 900,000 people. The first send reached far more people because it went to the whole list, he said, but about a month after launch fresh new subscribers stood at about 2,000 to 3,000, and he called it a small newsletter (watch at 12:59). ActiveCampaign passed $165M in ARR in 2021, its last publicly confirmed figure (per GetLatka). Step 2 starts the list; steps 3 and 4 are what grow it.

Which Tactics Fit Your List Size

Not every tactic makes sense on day one. Early on, direct outreach and a clear promise matter most; repeatable sources come next; paid acquisition comes last, once you know what a subscriber is worth to you. beehiiv’s own growth guide splits tactics by list size the same way, and its 2025 data gives a sense of pace: new launches on its platform reached a median of 482 subscribers in their first month, and median subscriber counts reached 8,314 by the end of year one. Those are medians on a platform built for newsletters, so a company newsletter for a narrow B2B audience may grow more slowly and still be worth it.

List size	Goal	Start with
0 to 1,000	Prove the promise	Customers, colleagues, founder profiles, community replies, a waitlist
1,000 to 5,000	Find one or two repeatable sources	Recommendations, guest posts, lead magnets, co-marketing, a web archive
5,000 to 10,000+	Scale what pays back	Referral program, paid recommendations, sponsored placements, ads

CJ Gustafson’s Mostly Metrics, a newsletter for finance leaders, shows how a B2B newsletter gets its first thousand readers. He told Nathan Latka in October 2023 that he searched Twitter for keywords from his articles, such as vertical software, replied with useful comments that linked back to his newsletter, and ran co-marketing with B2B companies such as Ramp and Brex. Launched in December 2020, Mostly Metrics had 35,000 subscribers by October 2023, 7,000 of them verified CFOs, with a 46% open rate on its latest send and minimum sponsorship rates of $5,000 to $10,000 per post (per GetLatka).

30 Newsletter Growth Tactics

Group the tactics by where each reader comes from. The first two groups cost time rather than money, so start there and add the others as the list grows.

Your Own Channels

1. A one-promise subscribe page: say who the newsletter is for, what each issue gives them and how often it arrives, and ask only for an email address.
2. Forms on your best blog posts: add an inline signup to the posts that already get search traffic, with an offer that matches the post’s topic. Our blog content strategy guide covers which posts to write first.
3. An exit pop-up: offer a useful resource when a visitor is about to leave, rather than a discount.
4. An opt-in in your product: add a newsletter checkbox at sign-up or in onboarding, so trial users keep hearing from you if they don’t buy right away.
5. One launch email to customers: announce the newsletter to your customers and users once and let them choose to subscribe.
6. Email signatures: add a subscribe link to your own signature and your team’s.
7. Founder and team profiles: put the subscribe link in the LinkedIn and X profiles of the people your buyers already follow.
8. A web archive: publish every issue on the web with a “start here” page, so issues can rank in search and new visitors can see what they’ll get.

Content That Pulls Readers In

9. Repurposed social posts: turn one idea from each issue into a LinkedIn or X post that links to the full issue. Our AI marketing prompts can help with the rewriting.
10. Lead magnets: templates, checklists and cheat sheets that solve one problem and lead into the newsletter.
11. An email course: five to seven short lessons on one problem, sent over a week or two, with the newsletter as the next step.
12. Free tools: a calculator or template that asks for an email address to save or export the result.
13. Webinars: every registration can become a subscriber if the form asks for permission.
14. Community answers: answer questions in the Slack groups, subreddits and forums your buyers use, and link an issue only when it answers the question.
15. Podcast and YouTube mentions: mention the newsletter in each episode and in the description.

The cheat sheet works because it is useful on its own and better with an email address. Josh Aharonoff, CEO of the fractional CFO firm Mighty Digits, posts finance and accounting content on LinkedIn and listed more than 85,000 daily newsletter subscribers on his slide. He described the format he uses to turn followers into subscribers:

A cheat sheet, as I like to call it: you get an infographic, it has all the information that you need, people bookmark it, they come back, they zoom in. Even better, you give a little link on the bottom, people can get it in high resolution. Now you have their email. Now you can warm them up via your newsletter, and eventually you can sell to them.

Borrowed Audiences

16. Recommendations: join the recommendation network on your platform and recommend newsletters your readers would like. beehiiv says newsletters that recommend others are 32x more likely to be recommended back.
17. Guest posts in other newsletters: offer your best idea to a newsletter your buyers already read, instead of publishing it yourself.
18. Cross-promotion swaps: trade a short mention with a newsletter of a similar size and audience.
19. Co-marketing with partners: write a joint issue, report or webinar with a company that sells to the same buyers.
20. Podcast guesting: go on shows your buyers listen to and give listeners one reason to subscribe.
21. Talks and events: end every talk with the newsletter’s promise and a short link.
22. A Product Hunt launch: launch the newsletter itself, not only your product.

Tom Orbach, a marketer who writes MarketingIdeas.com on Substack, reported more than 17,800 subscribers after its first year (August 2024). More than half came from borrowed audiences: about 5,600 from a Product Hunt launch and more than 4,000 from other writers’ Substack recommendations, plus sponsorships in other newsletters at around $6 to $10 per subscriber. He started with a waitlist of almost 700 people and said each of his LinkedIn posts brought at least about 150 new subscribers. These are one writer’s own numbers, not a benchmark.

Readers Who Recruit

23. A forward line: add a line at the top of each issue for people who got it from a colleague, with a subscribe link.
24. A referral program: reward readers for bringing in subscribers once the list is big enough that a few active fans make a difference.
25. Asks to your top readers: email your most engaged readers with one specific request, such as sharing an issue with their team.
26. A welcome email that asks for a reply: ask new subscribers to reply with their biggest problem. It tells you what to write and starts a conversation.

Paid, Once It Pays Back

27. Paid recommendations: pay other newsletters for each subscriber they send you. In beehiiv’s 2025 data, the average newsletter using Boosts, its paid recommendation feature, gained 84 new subscribers a month from it.
28. Sponsored placements: buy an ad in a newsletter your buyers read and point it at your subscribe page.
29. LinkedIn ads: promote your best issue or lead magnet to a narrow job-title audience.
30. Retargeting: show a subscribe offer to people who visited your pricing page or blog but didn’t sign up.

How to Use a Newsletter to Drive Sales

A B2B newsletter drives sales when it earns attention from the people who buy and then gives them one easy next step. Teach something your buyers need in every issue, mention your product only where it solves the problem the issue is about, and end with a single call to action, such as a trial, a demo, a webinar or an email course. In CMI and MarketingProfs’ 2026 survey, 54% of B2B marketers named email newsletters among their most effective thought leadership channels, and 63% measured thought leadership by business impact, such as leads and pipeline influence.

• Segment by role or interest: send product news to users and teaching issues to prospects, so neither group tunes out.
• Add a middle step: most readers aren’t ready to book a demo. An email course or a resource gives them a smaller yes first, and readers who still aren’t ready stay on the list for the next issue.
• Ask how they found you: add a “how did you hear about us” field to your sign-up and demo forms, so the newsletter gets credit when it works.
• Track every product link: tag the links in each issue so you can count trials and demos per issue, not only clicks.

Nils Liedlich, founder of Letter Leverage, which builds email courses for companies, described that middle step at SaaSOpen in September 2024. One client’s list grew from 559 to 5,533 new emails a month after it added an email course, according to his slides. For Category Pirates, whose new $1K digital product wasn’t selling to its email list, his team built a course about the product:

The interesting part here is that we found that the people that went through the [email course] converted 35 times better than the people that just went in from the [newsletter].

He sells email courses, so read these as one vendor’s client results rather than a benchmark.

Newsletter Metrics That Matter

Opens are the easiest number to see and the least reliable. Apple Mail Privacy Protection loads images automatically, which counts many emails as opened, and both beehiiv and Mailchimp warn about it next to their benchmarks. For reference, beehiiv reported an average open rate of 41.24% in 2025, and Mailchimp’s benchmarks put the average across all its users at 35.63% for opens and 2.62% for clicks (data as of December 2023). Track these instead:

• Net growth: new subscribers minus unsubscribes each month. A list that adds 500 and loses 400 is barely growing.
• Subscribers by source: which channel brought each reader, so you know where to spend your time.
• Click rate: the share of delivered emails with at least one click, compared with your own past issues.
• Replies: a reply is a reader telling you they care, and the best guide to what to write next.
• Sign-ups and pipeline per issue: trials, demos and deals that started from a newsletter link or named the newsletter as their source. To compare the newsletter with other channels, work out what each customer cost with our CAC calculator.

Paying for Growth Without Selling Equity

A newsletter compounds slowly. It can take many months to reach a list that moves pipeline, and the other channels still need funding while it grows.

Founderpath provides non-dilutive capital for B2B SaaS companies with at least $10K MRR. There’s no equity, no warrants, no board seats and no personal guarantees. Connect your billing, banking and accounting data, and most founders see funds within 24-48 hours.

Check what you qualify for. It takes less than 5 minutes.

Newsletter Growth: FAQ

How do I grow my newsletter from 0 to 1,000 subscribers?

Start with the people you already reach: customers, colleagues, your social followers and your email signature. Then go where your readers already talk, and answer their questions in communities and on social media with a link to an issue that helps. CJ Gustafson got the first thousand subscribers of Mostly Metrics, his newsletter for finance leaders, by replying to Twitter posts on topics he had written about and through co-marketing with B2B companies such as Ramp and Brex.

How long does it take to get 10,000 newsletter subscribers?

Usually more than a year, even on a platform built for newsletters. beehiiv reported that new launches on its platform reached a median of 482 subscribers in their first month and that median subscriber counts reached 8,314 by the end of year one, in its 2025 data, so the typical newsletter there is still short of 10,000 after twelve months. A B2B newsletter written for a narrow audience can take longer, and a small list of buyers can be worth more than a large general one.

What is a good open rate for a newsletter?

Recent platform averages sit between about 36% and 41%: beehiiv reported an average open rate of 41.24% in 2025, and Mailchimp’s benchmarks show an average of 35.63% across all its users (data as of December 2023). Apple Mail Privacy Protection counts many emails as opened automatically, so compare your rate with your own past issues and watch clicks and replies as well.

How do newsletters drive sales for B2B companies?

By teaching buyers something useful in every issue and giving them one next step, such as a trial, a demo or an email course. Track the product links in each issue and ask new customers how they heard about you, so you can count the trials and deals that started from the newsletter.

Do newsletter recommendations work?

Platform data says yes. beehiiv reported that newsletters in its Recommendation network grew 2.75x faster on average, and Substack said in February 2024 that recommendations and its app drove 50% of all new subscriptions on its platform. Both companies sell newsletter tools, so treat these as platform figures rather than an independent study.

Do newsletters still make money?

Yes. beehiiv reported that paid subscriptions on its platform earned $19M in 2025, up from $8M in 2024, and B2B newsletters sell sponsorships: Mostly Metrics reported minimum sponsorship rates of $5,000 to $10,000 per post in 2023 (per GetLatka). For a SaaS company, the bigger return is usually the customers the newsletter brings in.

Are newsletters still relevant in 2026?

Yes, especially in B2B. In CMI and MarketingProfs’ survey of 1,015 B2B marketers for 2026, 54% named email newsletters among their most effective channels for thought leadership, second only to LinkedIn. beehiiv reported that publishers on its platform sent 28 billion emails to more than 255 million unique readers in 2025.

What is the 3-2-1 newsletter?

It’s James Clear’s weekly newsletter, sent every Thursday. Each issue has 3 short ideas from him, 2 quotes from others and 1 question for the reader, and Clear says it goes to more than 3,000,000 people. A fixed format like this suits a busy B2B audience, because readers know exactly what they’ll get.
