The Mailchimp Style Guide stands as a prime example of a comprehensive website style guide, and an excellent resource for anyone looking for website style guide examples.

This holistic approach ensures that whether a user is interacting with Mailchimp's marketing materials, reading their support documentation, or using their product interface, the brand's personality remains recognizable and consistent. This has made it an industry benchmark, often cited by content strategists and UX writers.
This content-focused approach is a key differentiator for Mailchimp. The guide provides detailed writing guidelines covering everything from grammar and mechanics to specific word choices, ensuring consistent terminology across all communications. It also offers nuanced voice and tone recommendations tailored to different scenarios. For example, the tone used in a promotional email will differ from that used in a technical support document, and the guide addresses these nuances. Clear examples of correct and incorrect usage accompany each guideline, making it easy for writers and other content creators to understand and apply the principles.
