Keila
Keila is an open source newsletter tool designed to provide a reliable and easy-to-use way to work with newsletters. It is intended for people and organizations looking for newsletter software, especially those who want an open source option rather than a paid service. Its focus is straightforward: newsletter tooling with reliability and ease of use as its defining qualities. Keila is presented as an alternative to Mailchimp and Sendinblue, so it can replace either product for users whose needs are met by Keila. The available facts do not identify a specific feature gap, limitation, or workflow difference between Keila and those products. As a result, prospective users should not assume that it matches Mailchimp or Sendinblue feature for feature; that comparison is not provided here.
