What is keila.io?
Keila is newsletter software from Germany, fully open source under the AGPLv3 license, available either as a self-hosted installation or as a cloud service with EU hosting. Those who prefer not to rely on third-party infrastructure can run Keila on their own server without losing any features or hitting a paywall. This sets it apart from many SaaS providers that formally permit self-hosting but treat it as a second-class option. Developed and hosted in Germany, Keila is aimed explicitly at users who treat GDPR compliance as a technical requirement rather than a marketing promise. Tracking can be disabled entirely.
Core features
- Four editor modes: visual block editor, Markdown, MJML and plain text, selectable depending on workflow.
- Segmentation and custom data fields: contacts can be filtered by user-defined attributes and used for personalised campaigns.
- Analytics: open and click rates are tracked, but tracking can be turned off per campaign or globally.
- API access: Keila can be integrated into existing CRM or CMS systems via an API.
- Full data control with self-hosting: no vendor lock-in, no premium-tier restrictions.
Who is keila.io for?
NGOs, businesses and developer teams that send newsletters and cannot or do not want to transfer customer data to US-based services. Those who already operate their own server infrastructure can integrate Keila there. For teams without that infrastructure, the cloud offering with EU hosting is available. Automations (such as triggered email sequences) are still in development. Anyone who needs complex drip campaigns today will find a gap here.
Context & alternatives
Keila sits in the space of self-hostable email marketing tools. Listmonk is a similarly positioned open-source alternative, leaner and more focused on technical users. Mautic offers more automation features but is considerably more complex to set up and operate. For those migrating from Mailchimp or comparable SaaS services and who care about a German development background, Keila is the most straightforward migration path. The MJML editor is a concrete advantage for teams already working with that format.
