Currently, there is no specific information available regarding adding custom fonts directly to the newsletter feature in the New Outlook. The font options available in the newsletter feature may be limited to a predefined set that is supported by the application. If your preferred fonts are not appearing in this feature, it may be due to compatibility issues or restrictions within the Outlook application itself.
For general font management in Windows, you can ensure that your fonts are installed correctly in the system. You can add fonts through the Settings app under Fonts or by installing them directly into the Windows Fonts folder. However, this may not guarantee their availability in the Outlook newsletter feature, as it depends on the application's support for those fonts.
If you are looking for more flexibility in font usage, consider using web-safe fonts or those that are commonly supported across email clients, as they are more likely to render correctly in various environments.
