This is an example of an agent you can build in Sylvie: hand it a campaign brief (a launch, a sale, a newsletter, a re-engagement push) and it drafts the whole thing, subject lines, preview text, body, and CTA, across every email in the sequence. It runs on your brand brain (your voice, the live offer and its fine print, product facts, and the segments you send to), so the campaign is on brand and factually right before review. Sylvie does not ship it pre-built: you assemble it once on your own brand and run every campaign through it after that.
Sylvie does not ship this agent pre-built. It is an example of an agent your team can build with Sylvie, powered by your brand brain, so it runs your workflow the way you actually run it.
The Email Campaign agent is an example of what a marketing team can build on top of its brand brain in Sylvie. It handles the planned send end to end: the launch announcement, the sale sequence, the monthly newsletter, the win-back flow, drafted as a complete campaign rather than one email at a time.
Campaign email is high-stakes and repetitive at once. Every send needs a subject line worth opening, a body on brand, an offer stated exactly right, and a variant per segment, and it all has to ship on a calendar that never slows down. For an agency running promo calendars across clients, or an in-house team shipping a campaign a week, building this agent means the first draft of the whole sequence is ready to shape, not a blank ESP editor.
When you assemble the agent, you point it at your brand brain: the tone of voice, the offer and its terms, product facts and approved claims, the segments and what each one has been promised, and the campaigns that performed best. It reads the calendar context too, so a three-email sale sequence escalates the way it should and a newsletter reads nothing like a launch. For an agency, each client's brain is separate and permission-aware, so one brand's offer never lands in another's campaign.
Inside Sylvie you give it the brief, and it drafts the full campaign: subject line and preview options, body and CTA for each email, plus a variant per segment where you need one. It checks the whole thing against your approved rules and flags anything off-brand or off-offer, then the drafts land where your team works, ready to approve or push to your ESP. Every campaign you ship teaches the brain, so the next one starts from what already worked.
Draft every email in the campaign in one pass, not one message at a time, so a launch flow that took days is ready to shape in an hour.
The agent proposes subject and preview options drawn from what has actually worked for the brand, so you start from strong hooks instead of a blank line.
The live promo, price, and fine print come straight from the brain, so no email goes out with an expired discount or a claim the brand cannot make. Fewer legal rounds, fewer send-time scares.
Tailor the same campaign to each audience from what that segment was promised, so five on-brand variants take the effort of briefing one.
Run weekly campaigns for ten clients or ten segments without hiring ten more email writers. The agent carries the volume while your team keeps the strategy.
The subject line that beat the rest, the offer that converted, the segment note that mattered, all stay in the brain, so campaign knowledge does not leave when the email lead does.
A campaign is never one email. Here are real moments where teams point this agent at their brand brain and let it draft the whole thing.
A launch needs a three-email sequence (tease, launch day, last call) on brand and on message by Friday. Built on the brand brain, the agent drafts the full arc from the approved launch messaging in an afternoon, turning a multi-day copy project into a same-day review.
A weekend promo needs announcement, reminder, and final-hours emails that escalate without repeating themselves. The agent writes all three from the signed-off offer details, so the sale stays in the inbox all weekend and clears review in one pass instead of a back-and-forth on the discount.
The newsletter is always the thing that slips. The agent assembles it from the month's approved content and product facts in the brand's voice, so a send that used to eat a full day ships in under an hour, every month, without a dedicated writer.
A re-engagement campaign has to feel personal and stay compliant. The agent drafts the win-back sequence using only approved incentives from the brain, so the flow goes out on brand and legal-safe, recovering dormant revenue without a specialist agency retainer.
A single promo has to reach VIPs, new subscribers, and lapsed buyers differently. The agent tailors each variant to what that segment was promised, so you ship five on-brand versions for the effort of briefing one and lift response without more headcount.
The person who owns email is on leave and the calendar still has a send. Because the agent enforces the brand's voice, offers, and rules, a stand-in ships an on-brand campaign the same week, so no client goes dark and nothing off-offer slips out.
Those start from a template or a blank prompt and guess your voice and your offer every time. This is an agent you build on your own brand brain, so it already knows your tone, the live promo and its fine print, your product facts, and your segments, and it drafts the whole campaign against them. You get a sequence you can send, not a draft you have to fact-check and rewrite into brand.
Yes, because on brand here is not a one-off prompt, it is your brand brain: the voice, offers, and rules your team maintains in Sylvie. The agent drafts against that brain and flags anything off-voice or off-offer, so no email reaches a subscriber with the wrong tone or an expired discount.
Sylvie does not ship it pre-made, and it does not leave you with a blank editor either. You get the brand brain and the building blocks to assemble the agent, usually in an afternoon: you describe the campaign workflow you run and Sylvie wires it to your brain and your ESP. This page is an example of what teams build, not a product you switch on.
It reads the relevant parts on every campaign: your voice, the current offer and terms, product and pricing facts, segment promises, and the past sends that performed best. Nothing is hard-coded or re-pasted, so when you update the offer or the brain, the next campaign reflects it automatically.
That is the point. Every brand gets its own agent on its own brain, and within a brand you tune it per segment so each variant fits what that audience was promised. You decide the cadence, the number of emails, and how much a human reviews before anything sends.
Every brand runs in a separate, permission-aware brain, so one client's offers and lists can never be reached from another's campaign. The agent only reads what you have given it access to, everything it touches is logged and sourced, and nothing is used to train a foundation model.
