Article vs broadcast templates
Article mail follows the feed. Broadcast templates style a one-off letter to the list.
Article — used for RSS email when the feed has a new post. You pick the look on RSS email.
Broadcast — used when you write a one-off note (launch, correction, hello). Pro and Business only, with a monthly quota. You pick the letter structure when you compose.
Both follow the same privacy rules: no ads, no open tracking, unsubscribe and data-deletion links in the footer.
