When to use :type-selector in email

• Setting a base font-family on every <p> and <td> in the document.
• Resetting <a> color and underline globally before applying inline overrides.
• Establishing default <li> spacing for all unordered lists.

Rendering behaviour and edge cases

• Type selectors have very low specificity and are easily overridden by inline styles or class selectors.
• Outlook strips <style> blocks, so type selectors are inert there.
• Gmail honors type selectors when <style> survives but rewrites class names that interact with them.

Recommended fallback strategy

Treat type selectors in <style> as a baseline that may not apply. Always set critical typography inline on each text-bearing element. Use type selectors for non-critical refinements only.
