Hi!
When scheduling an article to be published at a future date, a notification email is triggered once it is saved. The email should have been triggered on the given publication date. Please kind look into this.
In addition, please do not forget to the multilingual support, especially using Falang in the next update. The users should be able to receive the published article in their preferred language, or in the default website language including a link to the same article in the other languages
