Frequently Asked Questions

How does sending newsletters through Listmonk work with Claude Code?
Upload-Post handles the Listmonk API behind a simple interface. When you tell Claude Code to send a newsletter, the skill sends the subject, body, and target list to the Upload-Post API, which creates and dispatches the campaign on your Listmonk instance. Subscribers receive the email just as if you sent it from the Listmonk admin panel.
Which subscriber list does the campaign go to?
You choose the target list by its list ID when you send the campaign, so each newsletter reaches exactly the right subscribers. This lets you run separate lists for product updates, digests, and announcements from the same instance.
How do I authenticate with Listmonk?
Listmonk through Upload-Post uses your instance URL together with your username and password. You connect those credentials once, and after that you can create and send campaigns directly from Claude Code without any manual API work.
Can I include formatting and links in the newsletter?
Yes. Listmonk campaigns support a formatted body with headings, links, and structured content, so your newsletter renders cleanly in subscriber inboxes. You compose the subject and body in Claude Code and send the campaign in one step.
Can I announce via Listmonk and other platforms simultaneously?
Yes. Upload-Post supports multi-platform publishing in a single API call. Include multiple platforms in your request, such as platform[]=listmonk&platform[]=x&platform[]=linkedin, and your announcement goes out by email and to your social channels at once. Each platform receives properly formatted content that respects its specific requirements.
