To enhance the visual appeal of HTML emails, custom fonts can be incorporated. This can be achieved by either hosting the font directly on your server, ensuring compatibility and correct formats, or by utilizing third-party font services like Adobe or Google Fonts.
However, it’s important to note that some email clients may not support custom fonts. In such cases, a fallback font is necessary.
The fallback font for HTML emails must be one of the following system default fonts:
- Palatino Linotype
- Times New Roman
- Comic Sans MS
- Lucida Sans / Console
- Trebuchet MS
