Brand & guardrails

Brand kit

Define colors, fonts, logo, voice, and reusable components once. Every email, sequence, and landing page is generated inside those constraints, so on-brand is the default, not a review step.

Lockable rules

Mark brand rules as required and Mailable blocks off-brand output at the source, whether a teammate or an LLM agent created it. Your colors can't be overridden and your logo can't go missing.

Consistency at scale

Because the brand kit constrains generation, whole teams and agents produce consistent email without a brand-police bottleneck. Update the kit once and future sends come into line.
