Introduction: What is an HTML Newsletter?
An HTML newsletter is a visually rich email that uses HTML code to include images, text formatting, colors, buttons, and layout styling — much like a webpage. Unlike plain-text emails, HTML newsletters give you full creative control to design eye-catching, branded content that resonates with your audience. Whether you’re promoting products, sharing updates, or inviting subscribers to an event, a well-designed HTML newsletter helps you stand out in crowded inboxes.
Why Use Mail Designer 365 for Your HTML Newsletters?
Mail Designer 365 makes it incredibly easy to create high-quality HTML newsletters — no coding required. With a powerful drag-and-drop editor completely native on your Mac and a library of professionally designed templates, you can craft beautiful emails in minutes. Our app is tailor-made for macOS and gives you full flexibility over layout, images, fonts, and colors, so every HTML newsletter looks exactly the way you want. Plus, everything is optimized for mobile and desktop inboxes right out of the box.
Customizing Your HTML Newsletter Design
Every design in Mail Designer 365 is fully customizable to match your brand and message. Swap out images, update text, adjust layouts, and tweak colors to suit your campaign. You can also add call-to-action buttons, videos, social media links, and even dynamic content like countdown timers. Whether you’re building a newsletter from scratch or adapting one of our Design Ideas, Mail Designer 365 gives you all the tools you need to bring your vision to life — and create an HTML newsletter that converts.
Export and Send
Once your HTML newsletter is ready, Mail Designer 365 gives you flexible options to send it out. For the fastest and most seamless experience, you can use our built-in Mail Designer 365 Campaigns tool to send newsletter blasts directly — no third-party tools required. For smaller distributions or one-off messages, the Direct Mail feature is perfect for sending emails straight from your Mac. Prefer to use an external service? You can also export your design as optimized HTML for platforms like Mailchimp, Campaign Monitor, and many others. Apple Mail is no longer supported due to changes in the app, but Mail Designer ensures your designs remain compatible across all major email clients.
HTML Newsletter Best Practices
To get the best results from your HTML newsletters, follow a few key best practices: keep your layout clean and focused, use mobile-friendly designs, and make sure your call to action is easy to find. Personalize your emails where possible, and always test your newsletter before sending to catch formatting issues. With Mail Designer 365, you’ll find built-in tools to help you preview your HTML newsletter on different devices, ensure accessibility, and stay on brand — giving you confidence with every send.
