What images are suited for email?

When it comes to creating engaging and effective emails, the use of images can be a powerful tool. Images can help to break up text and make an email more visually appealing, and they can also be used to illustrate a point or highlight important information. However, it's important to use images correctly in the email to ensure that they are displayed correctly and do not slow down the loading time of the email. This article will explore best practices for using images in email and provide tips for optimizing and formatting images to ensure they look their best in the inbox.

There are a few different image types that are well-suited for use in emails:

  • GIF (Graphics Interchange Format): GIFs are a type of image file that support transparent backgrounds and animation. They are best suited for small, simple graphics or short animations.

  • PNG (Portable Network Graphics): PNGs are a type of image file that support transparent backgrounds and high-quality graphics. They are a good choice for images that require a transparent background or need to be resized without losing quality.

  • JPEG (Joint Photographic Experts Group): JPEGs are a type of image file that is well-suited for photographs and images with lots of colors. They are a good choice for images that do not require a transparent background.

There are also a few things to consider when using images in an email:

  • File size: Large images can slow down the loading time of an email, so it's important to use small, optimized images whenever possible. You should aim for a file size of less than 500KB for each image.

  • Image dimensions: The dimensions of the images you use in an email will depend on the layout and design of the email. You should consider the size of the image in relation to the rest of the email and ensure that it is not too small or too large.

  • Image resolution: The resolution of an image refers to the number of pixels per inch (PPI) in the image. A higher resolution means that the image will be clearer and more detailed, but it will also result in a larger file size. You should aim for a resolution of 96 PPI for images in email.

  • Alt text: Alt text (alternative text) is a short description of an image that is displayed if the image cannot be displayed. It is important to include alt text for images in email to ensure that the content of the email is accessible to all users, including those who are using screen readers or have images disabled.

  • Image file type: Different image file types have different capabilities and characteristics. For example, GIFs support transparent backgrounds and animation, while PNGs support transparent backgrounds and high-quality graphics. You should choose the appropriate image file type for your needs based on the content and purpose of the image.
