Edit your newsletter in conversation with the assistant

Penpal, Letterhead’s assistant, sits in a panel beside whatever you’re working on. You tell it what you want in plain language — “shorten the subject line”, “make this intro punchier”, “swap in this story” — and it changes the newsletter for you. When it touches a draft, a preview of the finished email opens next to the conversation and re-renders as the work happens, so you can see the result without leaving the chat or reloading anything.

Open the assistant

Select the speech-bubble button in the top bar. The assistant slides out on the right; the page you were on stays visible beside it, so you can keep working while the conversation is open. On a narrow screen it opens as a full-width panel instead.

The button is in the top bar on every page, so you can reach the assistant from your newsletter list, the composer, your reports, or your settings — wherever the question comes up. Select it again to close the panel; your conversation is still there when you come back.

Ask for a change

Type what you want in the message box and send it. The assistant works with your real newsletters, so you can refer to them the way you’d say it out loud, and it knows which page you’re on — “this draft” is enough when you’re looking at one.

Things it can do with a newsletter:

• Read a draft back to you — its subject line, preview text, status, and what’s in it.
• Change the subject line or preview text — including asking for a few options to choose from. This works on any newsletter.
• Rewrite the words of a draft it wrote — tighten the introduction, change the tone of a section, cut a paragraph down. See the note below on which drafts this covers.
• Pull in content — add a story you point it at, or something from your Curations library.
• Answer questions about how a send performed — opens, clicks, and the numbers behind your last newsletter.

Which drafts the assistant can rewrite

If you asked the assistant to draft a newsletter, it owns that draft’s wording and can keep editing it for you. A newsletter you built yourself in the composer is made of blocks, and its body is edited there — so if you ask the assistant to rewrite a section of one, it will tell you that and leave the body alone. Its subject line and preview text are still yours to change by asking.

Some example asks:

• “Make the opening two sentences punchier.”
• “Give me three subject lines for this issue.”
• “Shorten the second section — it’s twice as long as the others.”
• “Add the piece about the new library branch after the events roundup.”
• “How did last Thursday’s newsletter do?”

The assistant only changes something when you ask it to. It won’t edit or send a newsletter on its own.

Ask it to take you somewhere

As well as answering, the assistant can move you around the app. Ask for a screen and it opens it, instead of telling you which menu to look under — “take me to my drafts”, “open the audience page”, “show me the analytics for the morning briefing”. It tells you where it’s taking you, then takes you there, and the panel stays open beside the new screen so you can keep talking.

It can reach the screens you’d normally click to: your newsletters, templates, automations, and curations; your audience; your analytics, reports, and goals; your promotions; your brand kits and image gallery; your settings, integrations, and team; your notifications and your own account. Name a newsletter and it opens that newsletter’s own editions, automations, audience, analytics, reports, or settings.

If you work in more than one Letterhead workspace, you can ask to move between them — “switch me over to Riverside” — using whatever you normally call it. A workspace is a separate place to work, so this one reloads the page, and you’ll start a fresh conversation on the other side.

It can only take you where you can already go. Ask for a newsletter or a workspace you don’t have access to and it says so instead of moving you — the same permissions apply as when you navigate yourself. If it can’t find what you named, it’ll ask you to name it the way it appears in your menus.

Watch the draft update beside the conversation

As soon as the assistant works on a draft, a Live preview pane opens to the left of the conversation showing the newsletter as a reader would receive it, with the draft’s title above it. Each time the assistant makes another change, the preview re-renders — so you can ask for a rewrite, read it in place, and ask for another pass without opening the composer.

Close the preview with the × in its header when you want the room back. The draft itself keeps every change the assistant made; closing the preview only hides the view.

The preview appears on desktop-width screens, where there’s space for it beside the conversation.

If the newsletter is open in the composer

You can have a newsletter open in the composer and talk to the assistant at the same time. When you ask it to change the subject line or preview text, the new wording drops straight into the fields you’re looking at, and a short message tells you it’s arrived.

It isn’t saved yet. Save the newsletter the way you normally would to keep the new wording — or change it again yourself first, since it’s just sitting in the editor like anything else you typed.

Start over, or pick up an earlier conversation

The ⋯ menu in the panel header has two entries:

• New chat clears the conversation and starts fresh. Penpal greets you differently each time, so a new conversation doesn’t feel like a form.
• Chat history opens your past support conversations, so you can re-read one or carry it on.

When you’d rather talk to a person

Ask for a human at any point — or select Talk to a human — and the assistant hands the conversation to Letterhead’s support team in the same panel. They can see the conversation so far, so you don’t have to explain it twice. If you go back to working with Penpal and support replies later, a line appears at the top of the panel to take you back to that thread.

Good to know

• You don’t have to be a company administrator. If you’re responsible for one or more of your company’s newsletters, you can use the assistant. It stays scoped to the newsletters you’re responsible for and never reaches channels outside them.
• It works in plain language, not codes. You’ll see newsletter titles, dates, and channel names — never internal identifiers.
• Send is still yours. The assistant drafts and edits; scheduling and sending stay where they always were.
• Don’t like a change? Ask for another. There’s no undo button for something the assistant changed, so the way back is forward — tell it what you’d rather have and it will change it again.
