Email Sequence Builder: Flow Logic, Timing, and Copy
Turns a goal into a ready-to-build email flow: trigger, exit rules, behavior branches, send timing, and full copy for every email.
Before & after
Same prompt, same agent — the only difference is the skill.
Here's a welcome sequence structure for SaaS trial signups: Email 1 (Day 0): Welcome and getting started Email 2 (Day 2): Highlight a key feature Email 3 (Day 5): Share a use case or success story Email 4 (Day 10): Check in and offer help Email 5 (Day 13): Trial ending reminder with upgrade CTA Tips: - Keep emails focused on one action - Personalize where you can - Make the value clear - Include clear CTAs Would you like help writing the copy for any of these?
WELCOME SEQUENCE — 14-day trial. The mistake most sequences make is
selling the product; this one drives to the ACTIVATION moment, because a
trial that activates converts and one that doesn't never will.
FIRST: WHAT'S THE ACTIVATION EVENT?
Not "logged in" — the first real outcome (first report built, first
integration connected). Every email below points at it.
DAY 0 — one job: get them to the activation event
Subject: "Your first win in 3 minutes"
Not a feature tour. One link to the single action that matters.
DAY 1 — did they activate?
Activated → skip ahead to depth. Not activated → this email removes
the specific blocker (branch the sequence here; this is the highest-
leverage email).
DAY 3 — the second-value moment
Now that they've felt one win, show the feature that compounds it.
DAY 6 — proof
A concrete result from a similar user. Numbers, not adjectives.
DAY 10 — the objection
Handle the top reason people don't convert, directly.
DAY 13 — trial ending
Urgency + the outcome they've already felt. "You built X; keep it."
THE BRANCH THAT MATTERS
Day 1 splits activated vs. not. Sending the same day-3 feature email to
someone who never completed step one wastes the whole sequence.
For in-app onboarding (vs. these emails), that's onboarding-cro. Want
the full copy for the day 0 and day 1 emails?About this skill
Your welcome emails go out on a fixed calendar, so people who finished setup yesterday still get the 'here's how to set up' email. Customers who already paid get the discount email. Opens look fine and nobody converts. This skill designs the flow logic before writing any copy. Every email reacts to what the reader did, does one job, and stops the moment they convert.
What it does
- Writes a build-ready flow spec: goal event, trigger, entry filter, exclusions, exit conditions, and priority against your other flows
- Bases timing on the right clock: hours after an abandoned cart, days back from trial end, or a milestone that hasn't happened yet
- Branches on clicks, product events, and purchases instead of unreliable open data
- Writes full copy for each email: sender, subject plus preheader pair with an alternate, body, and one deep-linked CTA
- Diagnoses a flat existing flow in a fixed order: deliverability, then trigger, timing, subject, body, and offer
- Flags compliance and deliverability risks: unsubscribe requirements, complaint rates, sunset rules for inactive subscribers
What you get
A flow map table plus send-ready copy for each email, with a measurement plan (goal conversion against a holdout, plus guardrail metrics) and clearly marked assumptions and placeholders.
Best for
SaaS founders and growth marketers setting up trial or onboarding emails, ecommerce operators building cart and post-purchase flows, and creators who need welcome, launch, or win-back sequences that convert instead of just getting opened.

name: email-sequence-builder
description: Designs and writes automated email sequences (welcome, trial onboarding, B2B nurture, launch, cart abandonment, post-purchase, win-back). The result is a build-ready flow spec with goal event, trigger, exit and suppression rules, behavior-based branches, and timing, plus send-ready copy for every email. Use when the user says "write a welcome sequence", "build an onboarding email flow", "I need a drip campaign for my leads", "my trial users never convert", "nobody clicks my nurture emails", "set up abandoned cart emails", "win back inactive subscribers", or "review my email flow".
