Self‑hosted newsletter platform with flexible email delivery options
Keila lets you design, send, and manage newsletters using a WYSIWYG editor, sign‑up forms, and multiple delivery backends—from personal SMTP to AWS SES, Sendgrid, Mailgun, and Postmark.
Keila is a self‑hosted newsletter solution that provides a full‑featured campaign editor, built‑in sign‑up form generation, and support for a range of email delivery services. Whether you run a small community list or a growing startup audience, you can start with a simple SMTP inbox and scale to providers such as AWS SES, Sendgrid, Mailgun, or Postmark without changing the UI.
The application is packaged as an official Docker image (pentacent/keila) and includes a ready‑to‑use Docker Compose file, making local or cloud deployment straightforward for teams comfortable with container orchestration. Released under the AGPL‑3.0 license, Keila gives you full access to the source code, allowing custom branding, template tweaks, or deeper integrations while avoiding vendor lock‑in.
Ideal for developers, NGOs, and small‑to‑medium newsletters that value data ownership, cost transparency, and the ability to tailor the mailing workflow to their own infrastructure.
When teams consider Keila, these hosted platforms usually appear on the same shortlist.
