Email Newsletter
An email newsletter is a regularly scheduled email sent to subscribers containing curated news, insights, updates, or educational content on a specific topic.
What Is Email Newsletter?
The term 'email newsletter' distinguishes traditional email-based newsletters from other newsletter formats (like Substack Notes or LinkedIn newsletters, which are platform-native). Email newsletters are sent directly to subscribers' inboxes through email infrastructure, giving creators full control over delivery and formatting. Modern email newsletters have evolved far beyond plain text updates — they include rich HTML designs, embedded images, interactive elements, and personalised content sections. The email newsletter format remains dominant because email is universal (everyone has an email address), direct (no algorithm filtering), and measurable (detailed analytics on every send).
Why It Matters for Newsletters
Despite the rise of social media and messaging apps, email newsletters remain the most effective channel for building deep, direct relationships with an audience. They work across all devices and email clients, don't require platform-specific accounts, and give creators full ownership of their distribution channel.
Best Practices
- Design for mobile first — over 60% of emails are opened on mobile devices
- Use responsive HTML templates that render well across email clients
- Include a plain text version for accessibility and deliverability
- Test your newsletter in multiple email clients before sending
- Keep file size under 100KB to avoid clipping in Gmail
