Text & Fonts

WOFF2 base64 encoded

By base64 encoding a WOFF2 file, the entire font can be embedded as part of the email payload, instead of downloading it from the web when the email is opened.

Embedded fonts are supported in some of the email clients where webfonts are disabled for privacy or security reasons.
