Implementing a style block involves embedding CSS within the HTML code of your email. This can be done within the <style> tags at the top of the email’s HTML file. For example:
<style> body { font-family: Arial, sans-serif; } h1 { color: #333333; } p { font-size: 14px; } </style>
This code will style the body with the Arial font, set the color of headings to a specific shade of gray, and define the font size for paragraphs.
