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
