  title: Mailchimp Create Template, Build Campaign, and Send
  summary: Create a reusable template, build a campaign from it, then send.
  description: >-
    A template-driven send pipeline. The workflow saves a reusable HTML template
    to the account, creates a regular campaign for an audience, sets the
    campaign content from the new template by passing its id, and sends the
    campaign. The template id threads from the create-template step into the
    set-content step, and the campaign id threads from create through send.
    Authentication uses HTTP Basic auth with any username and your Mailchimp API
    key as the password.
