Images can significantly impact the size of an email. Here are some tips to optimize them:
Use Appropriate Formats: Choose the right image format (JPEG, PNG, GIF) based on the type of image. For example, JPEG is best for photographs, while PNG is ideal for graphics with fewer colors. Compress Images: Use tools like TinyPNG or ImageOptim to compress images without compromising quality. Responsive Design: Ensure images are responsive and scale appropriately on different devices to avoid unnecessary loading of large images on smaller screens. Use Alt Text: Provide descriptive alt text for images to improve accessibility and SEO, as well as to convey the message if the image fails to load.
