The 70-20-10 Rule in Email Marketing: A Smarter Strategy to Engage, Educate, and Convert
Many businesses believe that sending more promotional emails will generate more sales. As a result, every campaign revolves around discounts, product launches, limited-time offers, and promotional announcements.
At first, this approach may deliver a spike in revenue. But over time, the results begin to change. Open rates decline, click-through rates drop, and subscribers gradually stop engaging. Some unsubscribe, while others simply ignore future emails.
The reason is simple, customers don’t subscribe to your emails just to receive constant sales pitches. They subscribe because they expect value, whether it’s useful insights, expert advice, exclusive content, or solutions to their challenges.
Successful email marketing isn’t about how often you promote your products; it’s about maintaining the right balance between educating, engaging, and selling. Brands that consistently provide value build stronger trust, improve customer relationships, and ultimately achieve better marketing results.
This is where the 70-20-10 Rule comes in. It provides a simple yet effective framework for balancing your email content—ensuring that every campaign contributes to long-term engagement rather than short-term promotions.
Quick Snapshot
The 70-20-10 Rule recommends structuring your email marketing strategy so that:
- 70% of your emails provide valuable, educational, or helpful content.
- 20% focus on curated content, community engagement, or relationship building.
- 10% are dedicated to promotional or sales-driven messages.
This balanced approach helps build trust, improve engagement, reduce subscriber fatigue, and ultimately drive better long-term business results.
In this guide, we'll explore:
Why the 70-20-10 Rule Matters
Today’s customers are exposed to hundreds of marketing messages every day. According to Radicati Group, the average professional receives more than 120 emails daily, making inbox competition fiercer than ever.
In such a crowded environment, brands that only send promotional emails often struggle to maintain subscriber interest.
The 70-20-10 Rule helps solve this challenge by creating a healthier balance between education, engagement, and promotion.
Instead of constantly asking customers to buy, businesses first establish themselves as trusted advisors. Over time, this strengthens customer relationships, improves engagement, and makes promotional campaigns more effective.
This approach also supports long-term business goals by reducing subscriber fatigue and encouraging repeat engagement.
Understanding the 70-20-10 Framework
70% Educational and Value-Driven Content
The majority of your emails should focus on helping your audience rather than selling to them.
Educational emails position your brand as a trusted source of information and keep subscribers engaged even when they’re not actively looking to make a purchase.
Examples include:
- Industry insights
- How-to guides
- Best practices
- Product tutorials
- Customer success stories
- Market trends
- Blog articles
- Webinars and educational events
Example
A marketing automation company sends an email titled: “7 Email Personalization Mistakes That Reduce Engagement.”
Instead of promoting its platform, the email shares practical advice marketers can immediately implement.
Subscribers gain valuable knowledge, while the company naturally builds credibility and trust.
20% Curated and Relationship-Building Content
Not every email has to originate from your own content.
The 20% portion focuses on strengthening relationships by sharing curated resources, customer stories, industry news, partnerships, or company updates.
This type of content keeps your audience informed while positioning your business as a valuable industry resource.
Examples include:
- Industry research
- Customer success stories
- Company milestones
- Community initiatives
- Partner announcements
- Event highlights
- Expert interviews
Example
A cybersecurity company shares: “Top Five Cybersecurity Trends Every Business Should Watch This Year.”
The email summarizes insights from a respected industry report while adding the company’s own perspective.
Rather than selling a solution, the business demonstrates expertise and thought leadership.
10% Promotional Content
Promotional emails remain an essential part of any email marketing strategy.
However, under the 70-20-10 Rule, they should represent only a small portion of your overall communication.
By the time subscribers receive promotional messages, they have already experienced consistent value from your brand, making them far more receptive to offers.
Examples include:
- Product launches
- Limited-time discounts
- Free trials
- Demo invitations
- Upgrade campaigns
- Seasonal promotions
Example
After sending several educational emails about customer engagement strategies, a SaaS company sends: “Ready to Transform Your Email Marketing? Book a Free Demo Today.”
Because trust has already been established, subscribers are more likely to respond positively.
Putting the 70-20-10 Rule into Practice
Let’s look at how a SaaS company might structure one month of email communication.
| Week | Email Type | Example |
| Week 1 | 70% Educational | How to Improve Email Deliverability in 2026 |
| Week 2 | 70% Educational | Five Customer Journey Mistakes Marketers Should Avoid |
| Week 3 | 20% Community | Customer Success Story: Increasing Open Rates by 35% |
| Week 4 | 10% Promotional | Book a Demo and See Kenmail in Action |
Instead of sending four promotional emails, subscribers experience a balanced journey that builds trust before asking for action.
When Can You Adjust the 70-20-10 Rule?
The 70-20-10 framework is a guideline—not a rigid formula.
There are times when businesses may temporarily increase promotional communication, such as:
- Festive seasons
- Product launches
- Black Friday
- End-of-quarter sales
- New feature releases
The key is to return to a balanced communication strategy once the campaign period ends.
Benefits of Using the 70-20-10 Rule
Builds Customer Trust
Customers are more likely to engage with brands that consistently provide useful information rather than constant promotions.
Educational content establishes your business as a trusted advisor rather than just another vendor.
Improves Email Engagement
Subscribers who regularly receive valuable content are more likely to:
- Open emails
- Click through to your website
- Share your content
- Stay subscribed longer
A balanced content strategy naturally improves long-term engagement.
Reduces Subscriber Fatigue
Supports Better Lead Nurturing
Not every subscriber is ready to buy immediately.
Educational emails help nurture prospects throughout the buying journey until they’re ready to make a purchasing decision.
This is particularly valuable for B2B businesses with longer sales cycles.
Increases Long-Term Customer Value
Brands that consistently educate and engage customers often experience stronger loyalty and higher customer lifetime value.
Instead of chasing one-time sales, they build lasting relationships.
Does the 70-20-10 Rule Work for Every Business?
The 70-20-10 Rule is a strategic guideline—not a strict formula. Different industries may adapt the ratio depending on their audience and objectives.
For example:
- B2B organizations often emphasize educational content, whitepapers, webinars, and case studies because buying decisions involve longer research and multiple stakeholders.
- Ecommerce brands may temporarily increase promotional campaigns during festive seasons or major sales events while maintaining a balanced approach throughout the rest of the year.
- SaaS companies typically focus on product education, onboarding tips, feature updates, and customer success stories to improve adoption and retention.
The key principle remains the same:
Provide significantly more value than promotional messaging.
Common Mistakes to Avoid
Even when businesses understand the 70-20-10 framework, they often make mistakes that reduce its effectiveness.
Avoid these common pitfalls:
- Treating every email as a sales opportunity
- Creating educational content that doesn’t address customer needs
- Sharing outdated or irrelevant curated content
- Ignoring audience segmentation and personalization
- Sending the same content to every subscriber
- Measuring only short-term sales instead of long-term engagement
The goal isn’t simply to reduce promotional emails—it’s to make every email more meaningful.
Final Thoughts
Successful email marketing is built on relationships, not just campaigns.
While promotional emails are important, they become far more effective when supported by valuable educational content and meaningful customer engagement.
The 70-20-10 Rule provides a practical framework for achieving that balance. It encourages businesses to focus less on constant selling and more on building trust, nurturing relationships, and delivering value at every stage of the customer journey.
When subscribers consistently find your emails useful, they’re more likely to stay engaged, remain loyal, and respond positively when you do present an offer.
In today’s competitive inbox, the brands that educate, engage, and inspire—not just promote—are the ones that earn lasting customer attention.
