Optimizing HTML code can also contribute to reducing email size. Here are some strategies:
Minify HTML: Remove unnecessary whitespace, comments, and characters from the HTML code. Inline CSS: Use inline CSS instead of external stylesheets to reduce the number of requests. Use Table-Based Layouts: While this may seem outdated, table-based layouts are still standard in email design and can help reduce code complexity. Optimize Fonts: Use web-safe fonts to avoid loading external font files.
