Built around how Listmonk actually works
Your server, your list
Postoni talks to your own Listmonk install with your API user. Subscribers and sending stay on your server.
Preview text that shows
Set the preview line people see in their inbox next to the subject, without it appearing in the email body.
Templates and lists
Pick one of your Listmonk lists and an optional template, loaded straight from your server.

Does Postoni publish automatically to Listmonk?
Yes. At the scheduled time Postoni creates a campaign on your Listmonk server and starts it, so emails begin sending right away.
Is there a character limit for Listmonk?
No. Newsletters can be as long as you like, though shorter emails tend to get read.
Can I test the email before it goes out?
Postoni shows a preview in the composer, but it doesn't send test emails. If you want a test send, do it from Listmonk, or schedule to a small test list first.
Does Postoni need my Listmonk server to be public?
Postoni has to reach your Listmonk API over the internet to create campaigns. A server only reachable inside a private network won't work with the hosted version.
