An example of an agent you can build in Sylvie: it takes the period's raw material (new posts, product news, customer wins, events) and assembles a complete newsletter draft with subject lines, preheader, sections, links and CTAs. It writes in the register your list is used to, not generic email filler. Running on your brand brain, it knows the segments, the offers currently live, the claims legal has cleared and what your audience opened last time.
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.
Newsletter is an example of an agent a marketing team or agency can build inside Sylvie to remove the weekly scramble: chasing links in Slack, rewriting the same intro, inventing a subject line at 6pm on send day. The agent takes what you already produced and turns it into a structured draft that matches your usual format, section by section, with the links and CTAs in place.
It is not an out-of-the-box email product. You assemble it in Sylvie around your own newsletter: your sections, your cadence, your segments, your sign-off. Because it sits on the brand brain, it inherits everything your team has decided about tone, product wording and promises, so a B2B client's operations digest and a DTC client's Friday drop email come out sounding like two different companies, because they are.
Before writing a word, the agent reads the brand brain: voice and register for email specifically (which is rarely the same as the website), the audience segments and what each one cares about, live campaigns and offers, product facts it is allowed to state, banned claims, and past issues with their performance notes. It also picks up your format rules, for example three stories maximum, one product item, always close with a customer quote.
Then it works inside Sylvie: it gathers the inputs you point it at (blog posts, release notes, event pages, a raw list of bullets from the team), decides the running order, writes each section at the length your template expects, drafts several subject lines and a preheader that does not repeat the subject, and inserts UTM-tagged links. You review, cut and edit in place. Approved issues and your edits go back into the brain, so the agent gradually learns which openings your list responds to and which ones you always rewrite.
Hand it links, release notes or rough bullets and get a structured issue back, not a blank page with a blinking cursor. The weekly send stops depending on one person's Thursday evening.
It drafts several options informed by what your brand brain says about this list and past open rates, instead of generic curiosity-gap tricks that clash with your tone.
The same issue can be recut for customers, prospects and partners, with the framing and CTA changed per segment rather than one flattened version sent to everyone.
Product facts, pricing and regulated wording come from the brand brain, so the agent does not invent a feature or overstate a result that legal already struck out.
Agencies rotating juniors across accounts get the same voice every week. New team members inherit the format instead of learning it by osmosis.
Every approved issue is stored in the brand brain, so the agent stops re-pitching stories you already ran and can reference what subscribers have already been told.
Marketing teams and agencies usually build this agent around the send that hurts most: the recurring one nobody has time for. Here is where it earns its place fastest.
A SaaS client sends every Tuesday and the draft is always late. The agent assembles Monday morning from the week's published posts, release notes and one customer story, so the marketer opens a near-complete issue and spends 40 minutes editing instead of four hours writing. Sends stop slipping to Wednesday.
One account manager runs newsletters for six brands, each with its own voice and calendar. The agent runs once per brand brain, producing six drafts that read as six different companies, and the AM's monthly newsletter block drops from three days to half a day.
A feature ships and the email needs to go out the same day, with wording that matches the release notes and the landing page. The agent pulls approved feature naming and benefits from the brain and drafts the announcement plus a shorter variant for existing customers, so the send happens on launch day rather than the following week.
A retail client is running a mid-season promotion with specific dates, exclusions and hero products. The agent builds the issue around the live offer stored in the brain, writes the urgency copy without overclaiming, and produces subject line options for A/B testing before the campaign window opens.
Twelve thousand subscribers have not opened in six months. The agent writes a win-back sequence framed around what those subscribers originally signed up for, using past issue performance in the brain to avoid the angles that already failed with them, and the team ships the sequence in an afternoon.
After a trade show you have a list of attendees and a pile of session notes. The agent drafts the follow-up email tailored to what the brand brain says that audience segment cares about, with the right next-step CTA, so follow-up goes out within 48 hours while the conversations are still warm.
No, and that is the point. Newsletter is an example of what teams build in Sylvie. You assemble it around your own format, cadence and segments, and it runs on your brand brain, so the first draft already looks like your newsletter rather than a template you have to dismantle.
Only if your brand brain is empty. The agent writes from the voice, past issues and editorial rules stored there, including the things you have banned. Teams that load real examples of their best-performing issues see the difference in the first run.
Yes. Agencies build the agent once and run it against each client's brand brain separately. Each brain carries its own voice, offers, claims and audience notes, so drafts never blend and nothing crosses between accounts.
It produces the draft and the variants for review. You stay in control of approval and sending, and you can hand the approved copy to whichever ESP you already use. The agent's job is the thinking and the writing, not pressing send behind your back.
You edit the agent. Add a section, drop the roundup, change the sign-off, move to fortnightly, and the next run follows the new rules. Because the format lives with your team rather than in a vendor's product, changes take minutes.
Approved issues, your edits and performance notes go back into the brand brain. Over a few months the agent learns which openings your list responds to, which stories you always cut, and which CTAs your audience actually clicks, and it drafts accordingly.
