Rules that usually apply

These are examples to adapt. Write your own rules in plain language, or use public rules, and every agent reads the same rule.

  • Claims need a source

    No superlative or performance claim appears without a cited source.

  • Brand voice

    The copy is direct and plain, in the voice of the brand guide.

  • Disclaimers

    Any offer includes the disclaimer text your policy requires.

  • Naming

    Product names are written exactly as the brand guide specifies.

Guide

How do I keep my brand guidelines in one place instead of in every agent?Split the guidelines by concern, save one rule for each, group them in a rule set, and update the set when the guidelines change.
