Frequently Asked Questions About Email Marketing Fonts
Frequently asked questions resolve common user queries regarding Outlook font rendering, mobile sizes, and Google web fonts. Read clear answers below prior to finalizing your email template designs.
Clearing up common rendering inquiries prevents design frustration when testing templates across multiple email clients.
What is the most readable font size for mobile email readers?
The most readable body font size for mobile email readers is 16px with a 1.5 line-height ratio. Setting font sizes below 14px forces mobile users to pinch-to-zoom, decreasing overall newsletter click-through rates.
Main section headlines should range between 22px and 28px to establish clear visual hierarchy on mobile screens.
Why does Microsoft Outlook override custom Google fonts?
Microsoft Outlook uses Word’s HTML rendering engine, which does not support external web font `@import` or `` declarations. When Outlook encounters unsupported web fonts, it reverts to your fallback font or default Word settings (Calibri or Times New Roman).
Including verified web-safe fonts like Arial or Georgia in your CSS font stack ensures Outlook renders clean fallbacks.
