How to Write a Newsletter with Midjourney

Midjourney is an AI image generation tool that can radically transform the visual quality of your newsletters. By creating unique, impactful visuals perfectly tailored to your editorial line, you capture your readers' attention as soon as they open the email. In this tutorial, you will learn how to use Midjourney to design original illustrations — banners, header images, thematic icons, and accompanying visuals — that will give your newsletter a professional and distinctive look. Say goodbye to generic stock images: each visual will be custom-made to reinforce your message and brand identity. Follow these steps to master the art of visually impactful newsletters with AI.

Prerequisites

1.An active Midjourney account with a current subscription
2.A Discord account to access the Midjourney server
3.An emailing platform (Mailchimp, Brevo, ConvertKit or similar)
4.A defined editorial line for your newsletter (theme, frequency, target audience)
5.Basic knowledge of visual composition and email layout

Steps

Define your newsletter's visual charter

Before generating images, establish a consistent visual framework. Identify your brand colors, desired artistic style (illustration, photorealistic, flat design, watercolor, etc.), and visual tone (corporate, casual, creative). Create a reference document listing these elements. This will allow you to write consistent prompts from one edition to another and maintain a recognizable identity for your subscribers.

Tip: Use the --sref (style reference) parameter with a reference image to maintain visual consistency across all your editions.

Create your newsletter's header banner

The banner is the first visual element your readers see. It must immediately communicate the edition's topic while staying true to your identity. Write a detailed prompt including the edition's theme, your graphic style, and a format suitable for emails (3:1 or 2:1 ratio). Generate several variations with Midjourney and select the one that best captures attention without visually overloading.

/imagine newsletter header banner about artificial intelligence trends 2026, futuristic abstract design, gradient from deep blue to purple, elegant typography space, editorial style --ar 3:1 --v 6 --q 2

Tip: Prefer the --ar 3:1 ratio for email banners. Leave empty space (negative space) to overlay your title with your emailing tool.

Generate illustration visuals for each section

Each section of your newsletter deserves a visual that reinforces the point. For an article on productivity, generate a metaphorical illustration; for news, create an editorial visual. Write a prompt per section using keywords from the style defined in step 1. Use the /describe command on existing images that inspire you to get prompt suggestions, then adapt them to your need.

/imagine editorial illustration for a newsletter section about remote work productivity, person working in a cozy home office with plants, warm lighting, isometric view, soft pastel colors, modern flat illustration style --ar 16:9 --v 6

Tip: Use the 'Vary (Subtle)' button to create slightly different variations of the same image, perfect for illustrating thematically linked sections.

Optimize and adapt images for email

Images generated by Midjourney are high resolution, which is unsuitable for emailing. Download your final images, then resize them to a maximum width of 600-800 pixels. Compress them to JPEG (quality 70-80%) or PNG for illustrations with transparency. Check that the total weight of your newsletter images does not exceed 1 MB to ensure fast loading. Systematically add a descriptive alt text to each image.

Tip: Use the --quality 1 (or --q 1) parameter during generation to get images of sufficient quality for the web without excessive resolution, which also speeds up generation.

Assemble the newsletter and test the rendering

Integrate your Midjourney visuals into your email template. Place the banner in the header, section illustrations next to or above each text block, and optionally add a call-to-action (CTA) visual at the bottom. Send yourself a test email and check the rendering on desktop, mobile, and in different email clients (Gmail, Outlook, Apple Mail). Ensure images display correctly and the newsletter remains readable even if images are blocked by the email client.

Common mistakes to avoid

✗Overloading the newsletter with AI-generated visuals, which increases total weight and slows loading — limit yourself to 3-5 images maximum per edition
✗Not maintaining visual consistency between editions by changing style each time, preventing readers from recognizing your brand
✗Using full-resolution Midjourney images (4096px) without compressing them, causing excessive loading times and truncated emails
✗Forgetting alt text on images, making the newsletter inaccessible and unreadable when images are blocked
✗Generating visuals with embedded text via Midjourney — AI-generated text often contains errors and is not selectable or translatable

FAQ

Which Midjourney subscription is recommended for creating newsletter visuals regularly?

The Standard plan ($30/month) is ideal for a weekly newsletter. It offers 15 hours of fast generation per month, allowing you to create about 200 images. For a daily newsletter or if you test many variations, opt for the Pro plan ($60/month) which offers 30 hours of fast generation and Stealth mode to keep your creations private.

Can I use Midjourney images in a commercial newsletter without copyright issues?

Yes, with a paid Midjourney subscription, you hold the commercial usage rights for your generated images. You can freely use them in your newsletters, even if monetized. However, note that with the free plan, images are under a non-commercial Creative Commons license. Check the current terms of use on the Midjourney website.

How can I maintain a consistent visual style from one newsletter to another?

Three techniques are essential: first, create a base prompt (template) that you reuse by only changing the subject. Second, use the --sref parameter with a reference image URL to enforce a consistent style. Third, save the seeds (--seed) of your best generations to reproduce similar results. Document these elements in a style guide dedicated to your newsletter.
