Design Studio API: manage email content end-to-end

You can now take an email through its whole lifecycle with the Design Studio API: create it from your own HTML, review and test it, link it to a workflow, and publish changes later.

You can build emails in your own tool and run them through Customer.io without manual steps in the editor:

• Create and update emails by pushing HTML through the Emails endpoints. You can also manage translations, folders, and custom components.
• Check emails before you send with the Email testing endpoints. Review an email for issues, preview it with sample data, send a test to your own inbox, or request inbox previews across email clients.
• Link an email to a workflow with the Linking and publishing endpoints. Attach it to an automation, broadcast, or transactional message, then publish future changes to push them live.
