Introduction
Not all fonts are compatible with all email environments. To ensure consistent display across all email clients, it's essential to understand best practices related to the use of standard and custom fonts.
What fonts are compatible with email?
In most cases, email clients only accept a limited number of standard fonts. The most commonly supported are : Arial, Verdana, Times New Roman, Georgia, Tahoma and Courier.
These so-called "web-safe" fonts are recognized by the majority of email services, enabling reliable display.
Custom fonts can be used, however, and may work if the recipient owns the font in question or if it is supported by their e-mail service. In all cases, we recommend using a substitute font.
font-family:'Roboto', Arial, sans-serif
In this example, the fonts Arial and sans-serif will be used if the font Roboto is not supported.
Note that this one is automatically set up when used in the Drag & drop editor.
Conclusion
Using custom fonts can enrich the visual aspect of an email campaign, provided you are rigorous in their implementation. A suitable substitute font is essential to guarantee a consistent reading experience for all recipients.
