Write a brief. Get a subject line and a full HTML body back, in your brand voice, at the length and in the language you asked for. Then edit it like a human, because you will. It's built into the platform — no eleventh tab, no thirteenth invoice.
Most people who buy a standalone AI writing tool use it for one thing: getting past the empty editor at 4pm on a Thursday. That is a real problem and it is worth solving. It is not worth a separate subscription, a separate login and a separate copy-paste dance into your email platform.
So we put it where the email is. The generator sits inside the campaign builder. What it produces drops straight into the body. What you like gets saved. What you want to test goes into an A/B split without leaving the page.
Illustrative output. Bracketed placeholders are deliberate — see below.
Not a prompt box and a prayer. You set the constraints before you generate, and the output respects them.
Brand Voice is set once, in settings, and shapes output across the account.
Brand Voice is a settings screen, not a prompt you retype every time. You give it the adjectives that describe your tone, the words you never want to see in your own emails, and sample text showing how you actually write.
Every generation after that is shaped by it. The forbidden-words list is the part people underestimate — it is the difference between copy that sounds like your company and copy that sounds like every SaaS landing page written since 2019.
It goes into the platform, where the sending happens.
One brief produces a subject line and a full HTML body. Not a paragraph you then have to format, and not a subject line you then have to write an email around. The body is HTML, ready for the campaign builder.
Generated copy is saved to a reusable library — create, edit, delete. The subject line that did well in March is still there in September, and so is the announcement structure you keep re-using with the words swapped out.
Generate several subject variants and push them directly into an A/B test on the campaign. You stop arguing about which line is better in a meeting and let the open rate settle it.
Usage is metered as AI generation credits, included with your plan. No separate AI add-on invoice, no per-seat licence for a writing tool you already pay for once. What you use comes out of what you have.
The failure mode of AI copy is not bad prose. It's confident, fluent, invented facts — a discount you never offered, a feature you never shipped, a statistic from nowhere. Sent to 40,000 people, that is not a typo. That is a problem.
So the system prompt is built to leave a bracketed placeholder rather than invent. Where it doesn't know, you'll see [YOUR_OFFER] or [FIRST_NAME] instead of a plausible lie. Filling those in takes ninety seconds. Retracting a fabricated claim takes considerably longer.
It also injects the unsubscribe URL. Generated copy that ships without one is copy that gets you into trouble, and the generator is not going to be the reason that happens.
You fill the brackets. The model does not guess at facts about your company.
The AI writer is one of the four tools that normally arrive as four invoices. Here it sits next to the others, on the same bill, working on the same data.
It will write a draft. A good copywriter will still beat it, and if you have one, keep them. What it reliably does is remove the blank page — a subject line and a full body, in your voice, in the length you asked for, in about the time it takes to make coffee. That is the job it is honestly good at.
We don't publish that, and we reserve the right to change it when a better option exists. What we will commit to is the behaviour: subject plus HTML body, your word count, your language, your emoji setting, your Brand Voice, and placeholders instead of invented facts.
Brand Voice, and specifically the forbidden-words list. Add the words you are tired of — the ones that show up in every AI draft — and they stop appearing. Add the adjectives that describe your tone and sample text from emails you actually sent. The output moves noticeably.
Yes. Generate variants and push them straight into an A/B subject test on the campaign. No copying between tools, no spreadsheet.
Nothing on top. Usage is metered as AI generation credits included with your plan. There is no separate AI subscription and no per-seat writing-tool licence.
No. The drag-and-drop builder, templates and campaigns all work exactly the same if you never touch it. It's a tool in the box, not a tax on the platform.
Brief in, subject and body out. In your voice, on your bill.
