What is a CSS File?
A
CSS file (Cascading Style Sheets) is a style sheet file used to define the look and formatting of a document written in HTML. In
email marketing, CSS files help in styling emails to make them visually appealing and consistent with the brand's design guidelines.
Importance of CSS in Email Marketing
Using CSS in email marketing is crucial for various reasons. It helps in maintaining a
consistent design across different email clients, enhances the
user experience, and increases engagement rates. Well-designed emails can lead to higher
conversion rates and better overall performance of marketing campaigns.
Can You Use External CSS Files in Emails?
Unlike web pages, most email clients do not support external CSS files due to security and privacy concerns. Therefore, it's essential to use
inline CSS or embedded styles within the HTML of the email. This ensures that the styles are applied correctly across different email clients.
