  title: Mailchimp Create Campaign, Set Content, and Send
  summary: Create a regular campaign, set its HTML content, then send it.
  description: >-
    The core email send pipeline. The workflow creates a regular campaign bound
    to an audience with its subject line and sender settings, sets the campaign
    HTML content, and finally triggers the send action. The campaign id returned
    by the create step threads through the content and send steps so an email
    goes out end to end. The send step is irreversible. Authentication uses HTTP
    Basic auth with any username and your Mailchimp API key as the password.
