How to Write an Email with Midjourney

Midjourney is an AI image generation tool that can transform your emails into visually striking communications. Although Midjourney does not directly write the text of your emails, it allows you to create professional visuals, custom illustrations, and graphic elements that capture the attention of your recipients. Whether you are preparing a newsletter, a marketing email, or a professional communication, integrating Midjourney-generated images significantly enhances the impact of your message. In this tutorial, you will learn how to use Midjourney to design visuals tailored to your emails, from defining the visual concept to final integration into your message. Follow these steps to create emails that stand out in your contacts' inboxes.

Prerequisites

1.A Discord account with access to Midjourney (active subscription)
2.A clear idea of the subject and purpose of your email
3.An email sending tool (Gmail, Outlook, Mailchimp, or other)
4.Basic knowledge of how Midjourney prompts work

Steps

Define the purpose and visual tone of your email

Before generating images, clearly identify the goal of your email: is it a newsletter, promotion, invitation, or prospecting email? Determine the desired tone (professional, creative, warm) and list the visual elements you will need: header banner, main illustration, icons, or visual separators. This planning step is essential to get results consistent with your message.

Tip: Create a quick mood board by gathering 3 to 5 examples of emails whose visual style inspires you before writing prompts.

Create a striking header banner with Midjourney

The header banner is the first visual element your recipient sees. Use Midjourney to generate an image that reflects the theme of your email. Favor a horizontal format (16:9 or 3:1 ratio) suitable for email headers. Leave space for overlaying text if necessary.

/imagine a professional email header banner for [YOUR_THEME], clean modern design, corporate style, soft gradient background, minimalist, 16:9 aspect ratio --ar 16:9 --v 6

Tip: Use the --ar 16:9 or --ar 3:1 parameter to directly get the right aspect ratio without cropping. Avoid overly busy images that would weigh down the rendering in the inbox.

Generate illustrations and accompanying visuals

Create visuals that illustrate the key points of your email. For a marketing email, generate product scenes. For a newsletter, create thematic illustrations for each section. Vary styles using Midjourney parameters to maintain visual consistency throughout the email.

/imagine [DESCRIPTION_OF_YOUR_VISUAL] for email newsletter, flat design illustration, professional color palette, white background, clean composition --ar 4:3 --v 6 --style raw

Tip: Use --style raw for more realistic and professional renders. Generate several variants with /imagine then select the best one with the U1 to U4 buttons.

Optimize and prepare images for email integration

Midjourney-generated images are often high resolution, which can slow down email loading. Download selected images from Discord, then resize them to a maximum width of 600 to 800 pixels. Compress them in JPEG or PNG format, aiming for a weight of less than 200 KB per image. Use a tool like TinyPNG or Squoosh for this step.

Tip: Most email clients display images at a width of 600px. Always test the rendering on mobile as over 60% of emails are read on smartphones.

Assemble the email and integrate Midjourney visuals

Write the text content of your email by structuring your message clearly: catchy subject line, engaging introduction, body with main arguments, and call to action. Integrate your Midjourney visuals at strategic points: banner at the top, illustrations between text sections, and a call-to-action visual at the end of the email. Host your images on a reliable service and use descriptive alt tags for accessibility.

Tip: Always add alt text to each image. If images don't load, your recipient will still understand the message. Send yourself a test email before any mass send.

Common mistakes to avoid

✗Using images that are too heavy, which do not load in email clients or land in spam
✗Generating inconsistent visuals by changing style with each prompt, resulting in a disorganized email
✗Forgetting to add alt text to images, making the email unreadable when images are blocked
✗Overloading the email with visuals at the expense of text content, harming deliverability and SEO
✗Not checking commercial use rights according to your Midjourney subscription before a professional send

FAQ

Can Midjourney write the text of my email?

Yes, provided you have a paid Midjourney subscription. Standard, Pro, and Mega subscriptions grant you commercial use rights for generated images. The free Basic subscription does not allow commercial use. Always check the current terms of service.

What image format is best suited for emails?

JPEG format is ideal for photos and complex illustrations as it offers a good weight/quality compromise. PNG format is better for images with transparent areas or sharp text. Aim for a maximum weight of 200 KB per image and a width of 600 pixels to ensure optimal display on all email clients.
