Email clients affect email design in several ways:
Rendering: Different email clients use different rendering engines. For example, Gmail and Apple Mail use WebKit, while Outlook uses Microsoft Word's rendering engine. This can result in varying displays of HTML and CSS. Support for Media Queries: Not all email clients support media queries, which are essential for responsive design. For instance, Gmail has limited support compared to Apple Mail. Font Support: Some email clients do not support custom fonts and will default to standard fonts. Image Blocking: Clients like Outlook may block images by default, affecting the visual appeal of your emails.
