Definition
AI image generation for email uses generative artificial intelligence tools to produce original images, illustrations and visual assets specifically for email campaigns. Instead of licensing stock photography or commissioning custom shoots, marketers can describe the visual they need in natural language and receive multiple generated options in seconds.
Common use cases include hero images for newsletters, product illustrations, background textures, icon sets and visual metaphors that reinforce a campaign theme. AI-generated images can be particularly useful for testing visual concepts before committing to full production.
Popular AI Image Tools
- DALL-E by OpenAI: Strong photorealism and complex scene composition
- Midjourney: High artistic quality, particularly for stylised and conceptual imagery
- Adobe Firefly: Integrated into Creative Cloud, commercially safe training data
- Stable Diffusion: Open-source model with extensive community fine-tuned variants
Best Practices
- Verify the licensing terms of the AI tool you use — commercial usage rights vary significantly between platforms
- Use AI-generated images for concept exploration and testing; validate with real audience data before full rollout
- Pair AI-generated visuals with strong alt text for accessibility and deliverability
- Be transparent if using AI-generated imagery for sensitive content such as customer testimonials or product photography
