Write newsletters and emails with AI

The Writer and its AI tools: topic ideas, draft a post from a brief, format pasted text, rewrite a passage, check your writing and suggest subject lines, in your own voice. Where each tool is, and what each message means.

Every workspace has the Writer, a one-page writing view for newsletter posts and broadcasts, with AI tools that help you pick a topic, write a first draft, tidy pasted text and polish what you've written. The AI never sends or publishes anything: it suggests, and you decide what goes in.

Who can do this

  • Owners, admins and staff can use the Writer and its AI tools.
  • Viewers see "You don’t have permission to use AI writing." The same message appears for everyone when a free trial has ended and the workspace is read-only.
  • Each AI request counts toward your plan's monthly AI writing allowance, including one that fails or is refused. See Limits below.

Open the Writer

  • Newsletter post: on a newsletter's Posts tab, click New post, or Edit on a post. See Write and publish newsletter posts.
  • Broadcast: on Marketing → Email, click New broadcast, or open a draft. In a broadcast, the Writer's title box is the Subject line. Sent broadcasts can't be edited.

Both open in the Writer. The Writer | Design switch at the top changes view: Writer ("Write the whole post in one document") is one long document; Design ("Lay out sections and blocks") is the block editor. Both edit the same post, so you can switch any time. Blocks the Writer can't edit, such as a video, show as a grey chip, "🔒 … — only editable in Design", with an Edit in Design button.

Drafts save themselves a moment after you stop typing (Draft · Saving…, then Draft · Saved). Your browser's spellcheck works in the Writer too.

Which tools are where

| | Newsletter posts and broadcasts (Writer) | Newsletter posts and broadcasts (Design) | Sequence emails and saved email templates | |---|---|---|---| | Topic ideas, Format text, Draft with AI | Yes, in the toolbar | Draft with AI with / | Draft with AI with / | | Rewrite a passage | ✨ AI rewrite… | ✨ Rewrite | ✨ Rewrite | | Check writing | Yes | No | No | | Suggest subject lines | ✨ Suggest in the Email row (newsletter posts) or by the subject (broadcasts) | Same | No |

Website pages and blog posts don't have these tools; for pages, see Build a page with AI.

Get topic ideas

  1. In the Writer's toolbar, click Topic ideas.
  2. Optionally fill in Focus (optional), for example "the spring cohort launch", and Audience (optional), for example "first-time course buyers".
  3. Click Suggest topics. You get up to eight ideas, each with a topic, an angle and, when it fits, Leads to: one of your products.
  4. Click Write this on an idea to open Draft with AI with its topic, key points and audience filled in. Suggest more gives another set.

Ideas come from what you sell, how many customers each product has and your recent newsletters. No customer names or emails are shared with the AI.

Draft a post from a brief

  1. Click Draft with AI in the Writer's toolbar.
  2. Fill in the brief:

- Topic (required), for example "Three mistakes new students make in week one". - Key points (optional), Audience (optional) and Call to action (optional). - Length: Short (about 300 words), Medium (about 600, the default) or Long (about 1,200).

  1. Click Write draft. The draft appears as it's written; Stop ends it early.
  2. When it says Draft ready, click Insert into post to add it at your cursor, or Discard. Write another tries again.

In Design, and in sequence emails and saved templates, type / on an empty line and pick Draft with AI instead. Fill in the same brief, then Insert as a new block. The Writer itself has no / menu.

Format pasted text

Use this for writing you already have, in a doc, your notes or an email.

  1. Click Format text in the Writer's toolbar.
  2. Paste into Paste your text (up to 20,000 characters).
  3. Click Format. The AI adds headings, sub-headings, quotes, bulleted and numbered lists and bold, and keeps your words.
  4. When it says Formatted, click Insert into post to add it at your cursor, or Discard.

If the AI changed your wording rather than only formatting it, you'll see "The AI changed your wording instead of only formatting it — try again, or format a shorter passage." Nothing is inserted.

Rewrite a passage

  1. Select up to 4,000 characters of text.
  2. Click ✨ AI rewrite… in the Writer's toolbar (in Design and the email editors, ✨ Rewrite on the formatting bar) and pick one:

- Shorten, Lengthen, Clarify, Rephrase or Fix spelling & grammar; - a reading level: Simple (age 10–11), Standard (age 13–14) or Advanced (adult expert); - a tone: friendly, professional, casual, confident or warm.

  1. The suggestion appears under the toolbar. Replace selection puts it in and keeps your formatting; Discard leaves your text as it was.

Check your writing

  1. Click Check writing in the Writer's toolbar. To check one part, select it first.
  2. The panel lists suggestions marked Spelling, Grammar, Clarity or Tone, each showing the original and the suggested fix. Click Apply or Ignore on each, then Done.

It checks up to 12,000 characters at a time. On a long post it says which paragraphs it checked; select a passage to check the rest.

Suggest a subject line and preview text

  1. Write some of the email first: the suggestions come from it.
  2. Click ✨ Suggest next to the subject. You get five Subject lines and three Preview text options. Click one to use it.

Your writing voice

Under Marketing → Email → Voice, add up to 10 samples of your writing and a style guide. Draft with AI and Topic ideas use it, so drafts sound like you. Rewrite, Format text, Check writing and Suggest don't use it. See Set your writing voice in Create and send an email broadcast.

Limits

  • Monthly allowance: every AI request counts toward your plan's monthly AI writing allowance. When it's used up you see "You’ve used this month’s AI writing allowance (… a month). It resets on the 1st — or upgrade your plan for more." See Plans and billing.
  • Speed: each tool takes a few requests a minute. Faster than that: "You’re going very quickly — wait a moment and try again."
  • Sizes: rewrite 4,000 characters; Format text 20,000; Check writing and Suggest 12,000 of the email.
