What is a Fallback Image?
A fallback image is an alternative graphic that displays in place of the primary image when the latter fails to load in an email. This is common in email marketing where images may not load due to various reasons such as slow internet connections, email client settings, or image file issues.
Why Use Fallback Images?
Fallback images ensure that your message remains visually appealing and informative even when the primary images do not load. This can prevent a poor user experience and potential loss of engagement.
How Do Fallback Images Work?
Fallback images are usually included in the HTML code of an email. When the primary image fails to load, the email client automatically displays the fallback image. This is typically done using the srcset attribute in the <img> tag or by using CSS background images.
Benefits of Using Fallback Images
Improved Engagement: Users are more likely to engage with visually appealing content.
Consistent Branding: Ensure your brand's visual identity is maintained.
Better Readability: Prevents your email from looking broken or incomplete.
