Shopify Email Flow Builder

AI-powered email automation design agent — creates complete Klaviyo or Shopify Email flow blueprints with every email mapped out: timing, subject lines, copy angles, segmentation, and A/B test suggestions.

Describe your store, your product, or the flow you need. The agent builds the full sequence from trigger to exit, ready to hand to a copywriter or implement directly.

Commands

build flow <type>                  # build a complete flow blueprint (e.g. build flow abandoned cart)
abandoned cart flow                # abandoned cart recovery sequence (3-email default)
post purchase flow                 # post-purchase onboarding and upsell sequence
winback flow                       # win-back lapsed customers sequence
welcome flow                       # welcome series for new subscribers
browse abandonment flow            # browse abandonment trigger sequence
flow audit                         # audit an existing flow for gaps and optimizations
email copy angle                   # generate subject line + copy angle options for a specific email
flow save <flow-name>              # save flow blueprint to workspace

What Data to Provide

The agent works with:

Flow type — "build abandoned cart flow for a skincare brand"
Store context — product type, price point, brand voice, target customer
Existing setup — "I have a 2-email abandoned cart but it's underperforming"
Performance data — open rates, click rates, revenue per recipient if available
Platform — Klaviyo, Shopify Email, Mailchimp, or other ESP

No API keys needed. No platform integration required.

Workspace

Creates ~/email-flows/ containing:

memory.md — saved store profiles, brand voice notes, past flows
flows/ — saved flow blueprints (markdown)
copy-angles.md — library of subject lines and copy angles by flow type

The 6 Core Flows

Flow 1: Welcome Series

Trigger: New subscriber (email capture, not yet a customer) Goal: Build relationship, establish brand, drive first purchase

| Email | Timing | Purpose | |-------|--------|---------| | Email 1 | Immediately | Welcome + deliver lead magnet (if any), brand story | | Email 2 | Day 2 | Social proof — bestsellers, reviews, UGC | | Email 3 | Day 4 | Education — how to use / why you'll love the product | | Email 4 | Day 7 | Urgency offer — first-purchase discount or free shipping | | Email 5 | Day 10 | Last chance — expiring offer or simple "did we lose you?" |

Flow 2: Abandoned Cart

Trigger: Cart created, checkout not completed (1 hour minimum delay) Goal: Recover the sale without over-discounting

| Email | Timing | Purpose | |-------|--------|---------| | Email 1 | 1 hour after abandonment | Reminder — "You left something behind", no discount | | Email 2 | 24 hours after Email 1 | Objection handling — reviews, guarantee, FAQ | | Email 3 | 48 hours after Email 2 | Incentive — offer discount only if previous emails failed |

Segmentation split: suppress Email 3 discount for VIP customers (they convert without it).

Flow 3: Post-Purchase

Trigger: Order placed (first purchase) Goal: Confirm, delight, cross-sell, generate reviews

| Email | Timing | Purpose | |-------|--------|---------| | Email 1 | Immediately | Order confirmation + what to expect (shipping timeline) | | Email 2 | Day 3 | Product education — how to get the most from purchase | | Email 3 | Day 7 (or at delivery) | Check-in — "Did it arrive? How are you liking it?" | | Email 4 | Day 14 | Review request (post-usage, not at delivery) | | Email 5 | Day 21 | Cross-sell / complementary product recommendation | | Email 6 | Day 45 | Replenishment prompt (for consumable products only) |

Flow 4: Win-Back (Lapsed Customer)

Trigger: X days since last purchase (typically 90–180 days, adjust by product purchase cycle) Goal: Re-engage before customer churns permanently

| Email | Timing | Purpose | |-------|--------|---------| | Email 1 | Day 0 (trigger) | "We miss you" — no offer, just re-engagement | | Email 2 | Day 7 | What's new — new products, improvements, social proof | | Email 3 | Day 14 | Win-back offer — discount or bonus | | Email 4 | Day 21 | Final attempt — "Is this goodbye?" (sunset path begins) |

Sunset: if no engagement after Email 4, move to suppression list or low-frequency list.

Flow 5: Browse Abandonment

Trigger: Viewed product page, did NOT add to cart (session ended) Goal: Return visitor to the product while interest is warm

| Email | Timing | Purpose | |-------|--------|---------| | Email 1 | 4–6 hours after browse | Product spotlight — features, benefits, reviews | | Email 2 | 48 hours after Email 1 | Social proof focus — reviews, UGC, bestseller badge |

Note: only trigger if subscriber, not an existing customer in an active abandoned cart flow.

Flow 6: VIP / High-Value Customer

Trigger: Customer reaches spend threshold (e.g., 3+ orders or $500+ LTV) Goal: Reward loyalty, prevent churn, increase AOV

| Email | Timing | Purpose | |-------|--------|---------| | Email 1 | At threshold | VIP welcome — exclusive status, thank you | | Email 2 | Monthly | Early access to new products / sales | | Email 3 | Birthday or anniversary | Personal recognition + exclusive offer |

Subject Line Formulas

| Formula | Example | |---------|---------| | Curiosity gap | "This is why your [product] isn't working" | | Direct benefit | "Get [outcome] in [timeframe]" | | Social proof | "[X] customers swear by this" | | Urgency | "Last chance — [offer] ends tonight" | | Personalization | "[First name], you left something behind" | | Question | "Did something go wrong?" | | Number list | "3 things you didn't know about [product]" |

Segmentation Logic

Key segments to build in Klaviyo:

Engaged subscribers: opened email in last 90 days
Unengaged subscribers: no opens in 90–180 days (reduce send frequency, sunset after 180)
First-time buyers: 1 order placed
Repeat buyers: 2+ orders (exclude heavy discounters)
VIP: top 10% by LTV or order count threshold
Discount buyers: purchased only during sales (suppress from non-sale flows, protect margin)

A/B Test Suggestions by Flow

| Flow | Test Idea | |------|-----------| | Abandoned cart Email 1 | Timing: 30 min vs. 1 hour delay | | Abandoned cart Email 3 | Discount type: % off vs. $ off vs. free shipping | | Welcome Email 1 | With vs. without founder video/story | | Post-purchase Email 4 | Review request timing: Day 7 vs. Day 14 | | Win-back Email 1 | Emotional tone vs. product-led subject line |

Output Format

Every flow blueprint outputs:

Flow Overview — trigger, goal, total emails, estimated duration
Email-by-Email Blueprint — for each email: timing, subject line (3 options), preview text, copy angle, CTA, segmentation notes
Flow Logic Map — trigger conditions, exit conditions, branch logic (e.g., "if purchased, exit flow")
Segmentation Rules — who enters, who is excluded, branch splits
A/B Test Recommendations — 2–3 specific tests to run first
Performance Benchmarks — expected open rate, click rate, revenue per recipient by flow type

Benchmarks

| Flow | Avg Open Rate | Avg Revenue/Recipient | |------|--------------|----------------------| | Welcome | 40–60% | $3–8 | | Abandoned Cart | 35–50% | $5–15 | | Post-Purchase | 50–70% | $2–6 | | Win-Back | 10–20% | $1–4 | | Browse Abandon | 25–40% | $2–8 |

Rules

Always ask for product type and price point before designing flows — a $15 impulse product needs different timing than a $300 considered purchase
Never add a discount to abandoned cart Email 1 — train customers to wait for the offer; use reminder tone first
Suppress existing customers from welcome flows and new subscribers from win-back flows — overlap causes brand confusion
Flag when a store is on Shopify Email vs. Klaviyo — Klaviyo supports conditional splits and predictive analytics; Shopify Email does not
Recommend sunset logic for every win-back flow — unengaged subscribers hurt deliverability
Keep subject lines under 50 characters for mobile optimization (label when testing longer variants)
Save flow blueprints to ~/email-flows/flows/ when flow save command is used
