Optimize Images: Use tools to compress images without losing quality. Consider using formats like JPEG or PNG for better compression. Minimize Code: Clean up your HTML and CSS code to remove any unnecessary elements. This can help emails render faster. Use Inline CSS: Inline CSS can reduce the time it takes for an email to load compared to external stylesheets. Limit External Content: Minimize the use of external content that requires additional loading time. Test Emails: Use tools to test your emails in different email clients and devices to ensure they load quickly everywhere.
