Whether you want to promote discounts, share company news, or curate industry insights, email newsletters help businesses engage audiences in a personal and memorable way. But not all newsletters are created equal. In this comprehensive guide, we dive into the different types of newsletters with examples, so you can create targeted campaigns that attract and retain more loyal subscribers. Let’s explore the newsletter formats dominating inboxes today!
Why Email Newsletters Still Matter
Despite the rise of newer communication channels like social media and messaging apps, email marketing remains a highly effective strategy for brands. Email newsletters, in particular, continue to be a popular and profitable customer engagement tool. Here’s a quick look at why email newsletters are still going strong.
Email Continues to Be a Preferred Channel
Email is far from being a legacy technology. In fact, email usage has steadily grown over the past decade. There are currently over 4 billion email users worldwide, and that number is projected to increase to over 4.6 billion by 2025, according to Radicati Group.
People today actively use email for both professional and personal communications. On average, business users check their email 5.6 times per day while consumer users check it 3.9 times per day. Email remains the top channel for critical updates and notifications.
High Deliverability and Inbox Placement
With proper list building and email delivery reputation management, marketers can achieve over 90% inbox placement rates on commercial messages such as newsletters. Open rates for email range from 15-30% on average.
In comparison, newer channels like social media have much lower organic visibility. Less than 10% of a brand’s followers generally see social media posts without paid promotion.
Trusted Relationship Channel
Consumers have a long-established relationship with email as a channel. They are very comfortable sharing their inboxes and expect to receive updates from brands they know and engage with via email.
Email newsletters feel more personal and build deeper customer relationships than social media updates. Subscribers make an explicit choice to opt-in to receive a brand’s newsletters.
Flexibility for Varied Content
Email newsletters are highly versatile when it comes to types of content. Text updates, promotions, tutorials, surveys, and more can easily be formatted for the email channel.
Email also allows seamless linking to different resources, making it easy to drive traffic to websites, videos, podcasts, and other external content.
Better Measurement and Optimization
Email analytics provide in-depth visibility into subscriber engagement. Open rates, click-through rates, link performance, and unsubscribe rates can all be tracked to optimize future newsletter content.
A/B testing subject lines, content variations, designs, timing, and segments is also straightforward with email. The clear measurability of email newsletters enables continuous improvement.
Drives Strong ROI
According to Campaign Monitor, email marketing has a median ROI of 122% – significantly higher than most other marketing channels.
Many brands have built their entire business model around email newsletters. For instance, The Skimm generated over $20 million in annual revenue solely from their daily newsletter and related products.
Takeaways
Given email’s entrenched status as the preferred communication medium for most consumers and business users, it will continue to remain a highly relevant marketing channel.
Email newsletters enable meaningful customer engagement through curated content delivered directly to the inbox. With proper list growth and optimization strategies, brands can achieve strong ROI from newsletters.
The flexibility to communicate varied content, the trusted relationship email provides, and the rich analytics available make email newsletters a sustained platform for customer retention and revenue generation.

Measuring Newsletter Performance and Engagement
To continually improve email campaigns, marketers need to monitor key analytics and optimize based on data. Here are the main metrics and methods for gauging newsletter effectiveness.
Tracking Open and Click-Through Rates
Open and click-through rates indicate whether your content resonates with subscribers.
Open Rates
The open rate is the percentage of sent emails that were opened by subscribers. Example:
- Emails Sent: 100
- Emails Opened: 50
- Open Rate: 50%
Benchmark open rates range from 15-30% in most industries.
Factors impacting open rate include:
- Subject line quality and personalization
- Subscriber demographics and engagement levels
- Email category – promotional, transactional, etc.
- Preview text clarity and appeal
- Send day and time
Test different variables to lift your open rate.
Click-Through Rates
The click-through rate (CTR) is the percentage of opened emails which had at least one link clicked. Example:
- Emails Opened: 100
- Emails Clicked: 25
- CTR: 25%
Good CTRs range from 2-5%.
Elements influencing CTR include:
- Content quality, length, and formatting
- Call-to-action placement, design, and messaging
- Overall email layout and ease of reading
- Relevance of links and offers
- Trust in sender reputation
Optimize your emails to drive more clicks.
Monitoring Bounce and Unsubscribe Rates
Bounce and unsubscribe rates help gauge list health and deliverability.
Bounce Rates
Bounce rate measures what percentage of total emails bounced instead of being delivered. For example:
- Emails Sent: 500
- Emails Bounced: 15
- Bounce Rate: 3%
Ideally, bounce rates should be under 2%. High bouncing indicates issues like invalid, outdated, or spam-flagged email addresses on your list. Continued high bounce rates lead to worse deliverability and potential blacklisting.
Regular list cleaning, double opt-in, and engaged subscribers help minimize bouncing.
Unsubscribe Rates
The unsubscribe rate calculates how many recipients clicked to opt-out of your emails. Example:
- Emails Sent: 1000
- Unsubscribes: 20
- Unsubscribe Rate: 2%
Unsubscribe rates above 1-2% may signal your content is not resonating or subscribers feel overcommunicated with.
Ways to reduce unsubscribes include more relevant messaging, better list segmentation, finding optimal send frequency, and prominently displaying the one-click unsubscribe option.
Surveying Subscribers for Feedback
Directly soliciting input from subscribers provides actionable insights.
Ask for Email Subject Line Preferences
Survey subscribers on their favorite and least favorite email subjects. Adjust your subject line strategy accordingly.
Query About Desired Content
Ask subscribers what types of content and frequency of emails they prefer. Tailor your newsletters based on the responses.
Solicit Open-Ended Feedback
Posing open-ended questions like “How can we improve our newsletters?” uncovers pain points and new ideas from engaged subscribers.
Poll Subscribers About Email Cadence
If you want to increase or decrease send frequency, first survey subscribers on their preferences so changes align with readership desires.
Surveys provide valuable qualitative data to supplement quantitative analytics. Short, focused polls sent 1-2 times per year typically get the best response rates.
A/B Testing Subject Lines and Content
A/B testing compares the performance of two versions by sending each to a sample of your list.
Subject Line Testing
Subject lines make the first impression on subscribers. Try different options like:
- Emotional vs. Informational
Subject A: “This left us speechless!”
Subject B: “This week’s top news roundup”
- Addressing Pain Points
Subject A: “Is your website outdated?”
Subject B: “Website revamp guide”
- Long vs. Short
Subject A: “Our biggest sale of the year starts NOW!”
Subject B: “Big sale”
- Emojis vs. Text
Subject A: “Our 2021 📈 Financial Report”
Subject B: “Our 2021 Financial Report is here!”
Content Testing
Test content variations like:
- Headline phrasing
- Section order
- Call-to-action wording
- Link positioning
- List vs. paragraph format
- Visuals used
Winning combinations get sent to the full list.
Optimizing Send Times and Cadence
Picking the best days, times, and frequency boosts email metrics.
Day of Week Testing
Compare open and click rates between different weekdays. Many find:
- Early week is best for promotional emails
- Mid-week for educational content
- End of week for updates and newsletters
Adjust your calendar based on subscriber behavior data.
Time of Day Testing
Segment your list by time zone. Test sending at different times like:
- Early Morning: 8-9 AM
- Mid-Morning: 10-11 AM
- Lunch Hour: 12-1 PM
- Mid-Afternoon: 2-3 PM
- End of Day: 4-6 PM
Identify when your audience is most engaged.
Email Frequency Optimization
Gradually increase send cadence and monitor metrics to find the optimal rate, such as:
- Monthly
- Twice a Month
- Weekly
- Twice per Week
Higher frequency requires consistently valuable content to avoid irritation.
Key Takeaways
- Monitor open, click, bounce, and unsubscribe rates
- Survey subscribers for direct qualitative feedback
- Run A/B tests on subject lines, content, timing, and frequency
- Use data insights to create higher-performing newsletters
