Keila

Keila is an open-source email newsletter platform for managing contact lists, designing campaigns, and sending personalized newsletters. It addresses the challenge of creating emails that render consistently across devices and clients, while giving users control over their data through self-hosting or a managed service.

The platform offers multiple editor options, including a visual block editor, Markdown, MJML, and plain text. It includes email analytics with optional tracking, a form builder with custom fields, bot protection via captcha and double opt-in, personalization using Liquid templates and JSON contact data, and segmentation tools. Keila also provides a comprehensive API, CSV import/export, transactional emails, A/B tests, and marketing automations. It integrates with SMTP, AWS SES, Mailgun, Postmark, and Sendgrid, with a Zapier integration in private beta.

Keila is suited for individuals, teams, and organizations that want an open-source alternative to proprietary email marketing tools. It can be self-hosted using the official Docker image or used through Keila Cloud, which is hosted on European infrastructure. Keila Cloud is packaged in usage-based tiers that vary by monthly email volume, with unlimited contacts and projects across all plans. There is no free plan, though discounts may be available for open-source projects, non-profits, and small businesses.
