Email

Ship promo emails that sell and stay on brand.

This is an example of an agent your team can build in Sylvie: it writes the promotional email behind a sale, a launch or a seasonal push, from subject line to CTA to the fine print under the offer. It runs on your brand brain, so it uses the real discount, the real dates, the approved claims and the voice this brand actually sells in. Sylvie does not ship it ready-made: you assemble it once on your own brand brain, then point it at each new offer.

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.

What it is

What is the Promotional Email agent?

The Promotional Email agent is an example of what a marketing team can build on top of its brand brain in Sylvie. Give it an offer (20 percent off the spring range, a product launch, a webinar, a two-day flash sale) and it returns the whole email: subject line options, preheader, body, CTA and the terms legal insists on.

Promo email is where speed and accuracy fight each other. The offer changes on Tuesday, the send is Wednesday, and the one person who knows the exclusions is on a plane. Building this agent puts the offer rules, the voice and last quarter's winners in one place, so the fast version is also the correct one.

How it works

How the Promotional Email agent works

When you assemble the agent you connect it to the parts of the brand brain a promotion needs: tone of voice and the register this brand sells in, product facts and pricing, approved offer terms and exclusions, regional and legal requirements, and the promo emails that actually performed. You also set the shape you want back, for example three subject lines, one hero block and one secondary CTA.

After that you brief it inside Sylvie in a sentence: the offer, the audience, the send date. It pulls current facts from the brain instead of a stale brief, drafts against your rules, flags anything it cannot verify (a claim with no source, a discount that collides with an active promotion) and hands you a draft ready for review or export to your ESP. Update the brain with a new price or a new exclusion and the next draft reflects it without anyone re-briefing.

Key benefits

Why teams build this agent

01

Offer terms always correct

The discount, the dates, the exclusions and the small print come from your brand brain, not from a copy of last month's email. Wrong-price sends and apology follow-ups stop happening.

02

A campaign in an hour

Brief the offer, get subject lines, body and CTA ready to review. Work that used to fill a day now fits between two meetings.

03

Subject lines worth testing

Variants are grounded in what actually earned opens for this brand before, so your test slots go to real contenders instead of guesses.

04

Legal clears it faster

Required disclaimers, exclusions and regional wording are in the draft from the start. Review becomes a sign-off instead of a rewrite loop.

05

Peak season without panic

Black Friday and holiday calendars mean dozens of sends across brands. The agent carries the volume so the team spends the week on targeting and testing, not on formatting offers.

06

Promos that sound like you

A sale email is where brands slip into shouty generic retail voice. This one stays in the register your brand sells in, discount or not.

Use cases

Where it goes to work

Promotional email is the workhorse of the calendar, and every send carries its own trap. Here is where teams point this agent at their brand brain and let it run.

Black Friday across a client roster

Five brands, four sends each, one week. You build the agent on each brand brain and brief offers instead of writing twenty emails, so the whole peak calendar is drafted in two days and the team spends the rest of the time on segmentation and testing.

A product launch announcement

Launch copy has to match the positioning the team agreed in the brief, not a marketer's memory of it. The agent pulls launch messaging, price and approved claims from the brain, so the email is consistent with the landing page and the ads on the first draft instead of the third.

A flash sale announced Monday for Tuesday

The offer lands late and there is no time for a full copy cycle. The agent drafts the announcement, the reminder and the last-chance email in one pass, so a 24-hour promotion ships on time with the correct end date in every version.

Regulated categories with mandatory wording

Finance, health and alcohol clients carry disclaimers that cannot be paraphrased. The agent places the exact approved language from the brain into every send, which cuts compliance review from days to a single pass and takes the fine off the table.

One offer, several segments

A single promotion needs different framing for lapsed customers, VIPs and new subscribers. The agent writes each version against what that segment has already bought and already been told, so you ship three tailored sends for the effort of briefing one.

Reviving a promotion that worked last year

The client wants the spring campaign that beat target, refreshed for the current range. The agent reads the past winner and today's product facts from the brain and rebuilds it in minutes, keeping the structure that worked without repeating a dated offer.

FAQ

Questions, answered

A generic tool has no idea what your discount really is, which exclusions apply, or how this brand sounds when it sells. This is an agent you build on your own brand brain, so the offer, the claims and the voice come from your source of truth. You review a draft instead of fact-checking a stranger's guess.

No. Sylvie gives you the brand brain and the building blocks to assemble the agent, and this page is an example of what teams build with them. Assembling it is a conversation rather than a development project: you describe the promo workflow you want and Sylvie wires it to your brain, usually in an afternoon.

Offers come from the brain, not from the model. If a discount, a date or a claim is not in the brand brain, the agent flags it and asks instead of filling the gap, so nothing unapproved reaches your ESP.

Yes, with one agent per brand brain. Each client's promo agent reads only that client's offers, voice and rules, so a fashion retailer's aggressive discount language never bleeds into a private bank's send.

Wherever your workflow ends today. Teams review inside Sylvie, then push the copy to Klaviyo, Braze, HubSpot or a shared doc, and you can build the agent to output the exact fields your ESP template expects.

You update the brand brain once. Every promotional draft after that uses the new price or the new exclusion, so a mid-quarter change does not turn into a hunt through old briefs and stale templates.
