Customer.io Emails API

Create and manage the emails you build in Design Studio, along with their translations and versions. - **Emails** hold the content, envelope details, and transformers for the default language. - **Translations** are language variants of an email. Each one has its own content and envelope. - **Versions** are named checkpoints of an email's content. Design Studio saves one automatically every time you publish, and you can save, inspect, restore, or delete them yourself. Learn more about the [best practices](/integrations/api/design-studio/integrate/) for sending HTML through these endpoints.
