What is Newsletter?
A newsletter is a recurring email sent to subscribers on a regular schedule — weekly, biweekly, or monthly — containing curated content, updates, insights, or promotions designed to maintain engagement and drive action.

What is a Newsletter?
A newsletter is a regularly scheduled email that delivers value to subscribers — whether that’s industry news, educational content, product updates, or curated resources.
Unlike one-off promotional emails or transactional emails, newsletters follow a predictable cadence. Subscribers know when to expect them and what kind of content they’ll get. The best newsletters feel less like marketing and more like a useful briefing from a smart colleague.
Newsletter growth has surged. Substack alone hosts over 35 million active subscriptions, and Litmus reports that 87% of B2B marketers use email (primarily newsletters) as a distribution channel. The format works because it puts you directly in someone’s inbox — no algorithm deciding who sees your content.
Why Does a Newsletter Matter?
A newsletter gives you a direct line to your audience that no platform can take away. Social media reach is rented. Email subscribers are owned.
- Audience ownership — Your subscriber list belongs to you, not to Instagram’s or Google’s algorithm
- Consistent touchpoints — Regular newsletters keep your brand top-of-mind between purchases or engagements
- Traffic driver — Newsletters are one of the most reliable ways to push readers back to your website or blog content
- Revenue channel — The average email ROI is $36 per $1 spent, and newsletters are the backbone of most email programs
For businesses that publish content marketing assets regularly, a newsletter is the distribution engine that makes that investment pay off.
How a Newsletter Works
Running a newsletter well involves more than hitting “send” every Tuesday.
Content Strategy
Decide what your newsletter does for the reader. Does it curate industry news? Share original insights? Promote your products? The best newsletters pick one primary job and do it well. A “everything from our company this week” email rarely gets opened twice.
List Building
Subscribers come from website signups, lead magnets, content upgrades, and organic traffic. Use double opt-in to keep your list clean from the start. Quality beats quantity — 2,000 engaged subscribers outperform 20,000 uninterested ones.
Design and Format
Keep it simple. Most high-performing newsletters use minimal design — a clear header, readable text, and 1-3 calls to action. Complex HTML templates often break across email clients. Plain text or simple layouts perform just as well (sometimes better) for engagement.
Measurement
Track open rate, click-through rate, unsubscribe rate, and growth rate. A healthy newsletter sees 20-30% opens, 2-5% clicks, and under 0.5% unsubscribes per send. If any of these slip, diagnose whether it’s a content problem, a frequency problem, or a deliverability problem.
Newsletter Examples
Example 1: B2B thought leadership A SaaS company sends a weekly newsletter with 3 curated articles, 1 original insight, and a product tip. Open rates hover at 35% because subscribers know exactly what to expect and find it genuinely useful. Each issue drives 400-600 clicks back to their blog.
Example 2: Local business updates A dental practice sends a monthly newsletter with oral health tips, appointment reminders, and seasonal promotions. theStacc helps businesses like this by publishing SEO articles that attract new visitors — who then subscribe to the newsletter and enter the nurture cycle.
Common Mistakes to Avoid
Most businesses make the same handful of errors. Recognizing them saves months of wasted effort.
Chasing tactics without strategy. Jumping on every new channel or trend without a clear plan. TikTok one month, LinkedIn the next, podcasts after that — none done well enough to produce results. Pick your channels based on where your audience actually spends time, not what’s trending on marketing Twitter.
Measuring the wrong things. Tracking impressions and likes instead of conversion rate and revenue. Vanity metrics feel good in reports. They don’t pay the bills.
Ignoring existing customers. Most marketing teams focus 90% of their energy on acquisition and 10% on retention. The math says that’s backwards — acquiring a new customer costs 5-7x more than keeping one.
Key Metrics to Track
| Metric | What It Measures | Good Benchmark |
|---|---|---|
| Customer Acquisition Cost (CAC) | Total cost to acquire one customer | Varies by industry — lower is better |
| Customer Lifetime Value (CLV) | Revenue from a customer over time | Should be 3x+ your CAC |
| Conversion Rate | % of visitors who take desired action | 2-5% for websites, 15-25% for email |
| Return on Investment (ROI) | Revenue generated vs money spent | 5:1 is a common benchmark |
| Click-Through Rate (CTR) | % of people who click after seeing | 2-5% for ads, 3-10% for email |
Quick Comparison
| Aspect | Basic Approach | Advanced Approach |
|---|---|---|
| Strategy | Ad hoc, reactive | Planned, data-driven |
| Measurement | Vanity metrics (likes, views) | Business metrics (revenue, CAC, LTV) |
| Tools | Spreadsheets, manual tracking | Marketing automation, CRM integration |
| Timeline | Short-term campaigns | Long-term compounding strategy |
| Team | One person does everything | Specialized roles or automated workflows |
Frequently Asked Questions
How often should I send a newsletter?
Weekly is the most common cadence for engaged audiences. Monthly works for less content-heavy businesses. The right frequency depends on how much valuable content you can consistently produce — never send just to fill a schedule.
What makes a newsletter worth opening?
A compelling subject line gets the open. Consistently valuable content keeps subscribers coming back. If your newsletter saves readers time, teaches them something, or entertains them, they’ll keep opening it.
Should my newsletter sell or educate?
Primarily educate. The 80/20 rule works well — 80% value-driven content, 20% promotional. Subscribers tolerate promotion when it’s surrounded by content they actually want to read.
