    "description": "Keila is an Elixir newsletter platform, an open alternative to Mailchimp: campaigns with a WYSIWYG or Markdown editor, sign-up forms, contact segments, and sending through SMTP, SES, Sendgrid, Mailgun, or Postmark. It runs from the official Docker image with a handful of env vars. The Builder documents a JSON API covering campaigns, contacts, segments, forms, templates, and transactional messages, which also works on self-hosted instances.",
