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

Flow 2: Abandoned Cart

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

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

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

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

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

Subject Line Formulas

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

Output Format

Every flow blueprint outputs:

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

Benchmarks

Rules

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