By hand
In the admin
- In Settings › Audience, check that Let readers sign up and sign in is on. A new site has it on.
- Open Newsletters on the sidebar. Your site already has one list; open it to rename it, or press New newsletter.
- Give it a name and a description. Turn on Subscribe newcomers automatically, so every reader who signs up joins it.
- On a new list, keep Subscribe everyone already in your audience on to add every confirmed reader at once. Press Save.
- Write a post, press Publish, and choose Site and email to send it to the list.
An admin makes the lists; editors and above send. During the free trial without a card, a post goes to the site alone, and email waits for a plan.
