Cerberus is a set of annotated, responsive HTML email template patterns designed to work across popular email clients including Outlook and Gmail. It provides compartmentalized code blocks (fluid, responsive, and hybrid layouts) that can be combined and nested to build emails.

Use cases

  • build responsive html email templates
  • create newsletters that work in outlook and gmail
  • boilerplate for transactional email layouts
  • accessible html email patterns
  • email templates without a framework or esp lock-in

When to choose

  • you hand-code HTML emails and need reliable cross-client patterns
  • you need emails that render well in Outlook, Gmail, and mobile clients
  • you want annotated, copy-paste email code usable with any ESP

When to avoid

  • you need a full email design tool or drag-and-drop builder
  • you want a framework or library with programmatic APIs rather than static templates
  • you need MJML-style compilation or component systems
