Keila

Keila is an open-source, self-hosted email newsletter and marketing email platform. It helps teams and creators build mailing lists, design email campaigns, schedule/automate sending, and track engagement.

Key Features

• Audience management with lists and subscriber attributes (including imports)
• Campaign editor with reusable templates and drag-and-drop style blocks (email builder)
• Segmentation to target subsets of subscribers based on attributes/filters
• Automations for triggered or scheduled sends (e.g., onboarding/drip sequences)
• Email delivery via SMTP and support for transactional sending flows
• Analytics for campaign performance (e.g., opens/clicks) and delivery status
• Multi-user/team oriented workflows (accounts/projects) suitable for organizations

Use Cases

• Publish recurring newsletters for communities, products, or internal updates
• Run lifecycle email sequences (welcome/onboarding/drip campaigns)
• Replace hosted email marketing tools where data/control must remain in-house

Limitations and Considerations

• Email analytics accuracy depends on client-side tracking behavior (e.g., image blocking/privacy features)
• Deliverability depends heavily on correct DNS (SPF/DKIM/DMARC) and SMTP provider configuration

Keila is a practical alternative to hosted newsletter tools for organizations that need list management, campaign creation, and automation in one place. It focuses on the core newsletter workflow—create, segment, send, and measure—while keeping operations under your control.
