Ownership reviewed, controller unresolved
The current operator is Keila GmbH, HRB 8676 at Bayreuth, represented by managing director Philipp Schmieder. Its description as a bootstrapped business is not a shareholder or voting-control disclosure. The cloud ownership verdict remains unresolved; self-hosting gives the deploying organisation control of its own infrastructure.
Operational dependency warning
Relies heavily on non-European providers
Current public evidence shows 3 non-European infrastructure or email dependencies across 3 providers: Amazon SES, Amazon Web Services SMTP relay, Intuition Machines / hCaptcha. The reviewed operational path is therefore not entirely European.
Keila is an AGPLv3 open source platform for newsletters, contact lists and campaigns. Its API also supports transactional messages. It is available as Keila Cloud or can be self-hosted using Docker and PostgreSQL, with a sending provider chosen for your deployment.
Keila Cloud is operated by Keila GmbH in Germany. Its approved suppliers include Hetzner and Scaleway for servers. The Send with Keila option uses an AWS SMTP relay; customers can instead configure their own sender. The public legal notice identifies the managing director but does not establish the company's shareholders.
Pricing
Keila Cloud starts at 8 EUR/month before applicable taxes for 2,000 emails and unlimited contacts and projects. Higher plans increase the email allowance. There is no free cloud plan; the open source software can be self-hosted without a licence fee, with hosting and delivery costs paid separately.
