Choosing the right line height depends on several factors:
Font Size: Larger font sizes usually require larger line heights. A general rule of thumb is to use a line height of 1.2 to 1.5 times the font size. Content Length: For longer emails, a slightly larger line height can make the text more readable. Audience: Consider the preferences and needs of your target audience. For example, older readers might benefit from larger line heights. Design: Ensure that the line height complements your overall email design and maintains visual harmony.
