Step guidance

Hi! Let's build your font stack!

This tool builds the perfect font fallback stack for email. Outlook supports 900+ fonts, and Gmail has hidden font support that we have painfully tested - so your brand fonts are represented as closely as possible, no matter the email client.

Build your cross-platform email font stack in a few steps.
