What you can post

  • Newsletters up to 100,000 characters, in Markdown.
  • Up to 10 images, added below the text. Video isn't supported.
  • No threads or comments.
  • Per-post settings:
    • Email subject: required.
    • List: required. The choices come from your Listmonk server.
    • Send immediately (otherwise saved as draft campaign): on by default.

Connect your account

  1. In Listmonk, create an API user under Admin → Users.
  2. In Postline, click + Add next to Channels in the sidebar. Only workspace owners and admins can add channels.
  3. Choose Listmonk and fill in:
    • Listmonk address: for example https://lists.yourdomain.com.
    • API username.
    • API token.
  4. Click Add channel.

For self-hosters

No server setup is needed. People connect with their own Listmonk server and API user.

Images are linked from their Postline URL, so APP_URL/uploads/... (or your S3 public URL) must be reachable from the internet.

Analytics and plugs

Postline collects each campaign's views, clicks and number of emails sent (shown as impressions). It does not track subscriber counts.

Plugs (auto-repost and follow-up) aren't available for Listmonk.

Known issues

  • Every campaign needs a subject and a list.
  • With Send immediately turned off, the campaign is saved as a draft in Listmonk and you send it from there.
