Keila is an open source (AGPL-3.0) email newsletter tool written in Elixir, positioned as an alternative to Mailchimp or Sendinblue. It supports contact management, sign-up forms, contact segmentation with a JSON query language, multiple email editors (block/WYSIWYG, Markdown, MJML, plain text), optional privacy-friendly analytics, and sending via SMTP, AWS SES, Sendgrid, Mailgun, or Postmark.

Use cases

  • self-host a mailchimp alternative
  • send email newsletters to my contact list
  • create signup forms for a newsletter
  • segment subscribers and send targeted campaigns
  • send newsletters without tracking pixels
  • manage mailing list contacts with custom fields
  • send email campaigns via AWS SES or SMTP

When to choose

  • you want a fully open source, self-hosted newsletter platform with no vendor lock-in
  • you need privacy-conscious analytics or the option to disable tracking entirely
  • you want flexible email authoring: visual block editor, Markdown, MJML, or plain text
  • you need contact segmentation with custom fields and a JSON query language
  • you want to bring your own email delivery (SMTP, SES, Sendgrid, Mailgun, Postmark)

When to avoid

  • you need marketing automation, A/B testing, or transactional email workflows that are still on the roadmap
  • you want a managed free tier - Keila Cloud is paid and self-hosting requires your own infrastructure
  • you need advanced e-commerce or CRM features beyond newsletter campaigns
  • you prefer a tool in a language/stack other than Elixir for customization
