Marketing

Run your mailing lists yourself.

listmonk packages the working parts of a mailing operation into one self-hosted application. Subscribers can belong to several lists and carry structured attributes for segmentation; reusable templates feed campaigns and transactional messages; and the operator retains control of delivery configuration, bounces, analytics, roles, and data in PostgreSQL.

  • Organize subscribers into opt-in lists and attribute-based segments
  • Create reusable templates and send scheduled or immediate campaigns
  • Send transactional messages through an API with external-recipient support

What people use it for

Publish a recurring newsletter

Import or collect subscribers, organize them into lists, prepare a reusable template, schedule campaign delivery, and review views, clicks, bounces, and other campaign results.

Target a segment of an audience

Attach structured attributes to subscribers and query those values to create smaller audiences for relevant announcements, product updates, or regional communication.

Send application-triggered email

Configure a transactional template and call the API for welcome messages, order confirmations, password resets, or other events, including recipients outside the subscriber database when required.
