Fallback for Images If an image fails to load, using alt text is a common fallback. This text provides a description of the image and ensures that the recipient understands what the image is supposed to convey. Additionally, you can use a background color or a placeholder image as a fallback.
Fallback for Fonts When using custom fonts, it's important to specify a web-safe font as a fallback. This ensures that if the custom font fails to load, the text will still be displayed in a readable format. For example: css font-family: 'Custom Font', Arial, sans-serif;
Fallback for CSS Email clients often have varying levels of support for CSS. To handle this, you can use inline CSS as a fallback for more advanced styles. Additionally, it's good practice to test your emails across different email clients to identify any CSS issues.
Fallback for Interactive Elements Interactive elements like carousels and animated GIFs may not be supported by all email clients. A common fallback is to provide a static image or a text version of the content. For example, if an interactive carousel doesn't work, you can display a series of static images instead.
