The 7 Email Flows Every US Shopify Store Needs Running Right Now

Automated email flows are the engine of a high-performing email program. Unlike campaigns, which you plan, write, and send manually, flows run continuously — touching every subscriber, buyer, and lapsed customer at exactly the right moment, without you lifting a finger.

For US Shopify brands, flows typically generate 40–55% of total email revenue when built properly. Yet the median Shopify brand has 2–3 flows live, all underbuilt, and generates maybe 20–25% of email revenue from automation. The rest comes from manual campaigns, which require constant effort and stop the moment you stop sending.

Here are the 7 flows that change that ratio — what they are, what they should contain, and the revenue benchmarks to aim for.

Flow 1: The Welcome Series

What it is: Triggered when someone subscribes to your email list but has NOT yet made a purchase.

Revenue contribution: Welcome flows generate 10–20% of total email revenue for well-run programs. They’re the highest-leverage flow because everyone enters your list before becoming a customer.

The architecture (5 emails minimum):

Email 1 — Immediate (within 5 minutes of subscribe): Deliver whatever you promised at signup — a discount code, a content download, a quiz result. Do this fast. A subscriber who gets their welcome email 4 hours after signing up has already moved on. In Klaviyo, set a 0-minute delay or the minimum your trigger allows.

Beyond the delivery, this email should establish voice, brand promise, and set expectations for what they’ll receive.

Email 2 — 24 hours later: Brand story email. Why does your company exist? What problem are you solving? Who’s the founder, and why does it matter? This is the email most brands skip, and it’s a mistake — brand story emails drive some of the highest read rates in the entire flow.

Email 3 — 48–72 hours later: Social proof and product spotlight. Reviews, bestseller showcase, “most loved by our customers” angle. The job of this email is to overcome the primary barrier to first purchase: uncertainty.

Email 4 — 4–5 days later: Discount urgency. If they haven’t purchased, remind them the welcome discount expires in 48 hours. Include a focused product recommendation based on any browse data Klaviyo has collected since signup.

Email 5 — 6–7 days later: Final call. Last chance on the discount (if applicable), with a clear CTA and no other distractions.

Key optimization: Split your welcome series based on the subscribe source. Someone who signed up via a “get 15% off” popup has different intent than someone who signed up after reading a blog post. The popup subscriber needs faster urgency; the organic subscriber benefits from more brand education before the sell.

In Klaviyo, you can create conditional splits based on the $source property to fork these journeys.

Benchmark: A well-built welcome series converts 8–14% of subscribers to first-time buyers within 7 days.

Flow 2: Abandoned Cart

What it is: Triggered when a contact adds items to their Shopify cart and does not complete checkout. Different from checkout abandonment, which requires them to have started the checkout process.

Revenue contribution: Typically 15–25% of total flow revenue when properly built.

The architecture (3 emails):

Email 1 — 1 hour after abandonment: Your softest touch. Product reminder with high-quality imagery, clear price, one-click return to cart link. No guilt, no “you forgot something” framing. Just a helpful reminder.

Subject line approach: “Your [product name] is waiting” or “Didn’t finish? Your cart is saved.”

Email 2 — 24 hours after abandonment: Overcome objections. What stops people from buying this product category? Address it here. Shipping anxiety? Show your shipping policy and delivery times. Price concern? Highlight value/reviews. Uncertainty about fit? Link to your size guide or comparison content.

Email 3 — 3 days after abandonment: Final nudge + optional incentive. For mid-to-high value carts (above your average order value), consider including a small incentive — 10% off, free shipping — but frame it as a one-time offer with a 24-hour timer.

Important Klaviyo setup note: Make sure your cart abandonment flow excludes people who subsequently converted through another path. Use a “has placed order in last X days” filter on the flow itself. Nothing undermines trust like sending a cart abandonment email to someone who already purchased.

Benchmark: Recovery rates of 15–22% of abandoned carts when the flow is properly timed and segmented.

Flow 3: Checkout Abandonment

What it is: Triggered when someone starts the Shopify checkout process (enters their email) but doesn’t complete the purchase. This is different from cart abandonment — this person was much closer to buying.

Revenue contribution: One of the highest-ROI flows because the intent signal is so strong.

Why it needs to be separate from cart abandonment: The psychology is different. A cart abandoner was browsing. A checkout abandoner was in the process of paying. They may have been interrupted, had a payment issue, or gotten cold feet at the last moment. Your messaging should reflect that proximity.

The architecture (3 emails):

Email 1 — 30 minutes after abandonment: Acknowledge they were close. “It looks like you were interrupted — your order is saved.” Include an order summary with images, their shipping information if captured, and a direct link back to complete checkout.

Email 2 — 4–8 hours later: Address potential objections specific to the checkout stage: payment security, return policy, delivery time, and customer reviews. If you offer multiple payment options (Shop Pay, AfterPay, Klarna), mention them here.

Email 3 — 24 hours later: Urgency around stock or price. “We can only hold your items for a little longer” is acceptable if you actually have limited inventory. If you don’t, use a different angle: free shipping offer, or a customer review testimonial.

Benchmark: 20–30% conversion rate on checkout abandonments when all three emails are properly structured.

Flow 4: Post-Purchase Sequence

What it is: Triggered after a customer places their first order. (Use a separate flow for repeat purchasers.)

Why it matters: The period immediately after purchase is when buyers are most engaged with your brand — and most open to developing loyalty. Brands with proper post-purchase flows see 20–35% higher repeat purchase rates within 90 days compared to brands with no post-purchase sequence.

The architecture (4–6 emails):

Email 1 — Day 1–2 (after delivery confirmation or after estimated delivery window): Go beyond the transactional. Thank them warmly, remind them what to expect from the product, share tips for first-time use. This email should feel personal, not like a Shopify system notification.

Email 2 — Day 5–7: Product education. How-to content, tips, use cases. This is especially valuable for consumables, supplements, skincare, and anything that requires setup or learning.

Email 3 — Day 10–14: Review request. This is the optimal window for most categories — the product has arrived, they’ve used it, the experience is fresh. Use a direct subject line: “How’s your [product name]?” Link directly to your review form.

Email 4 — Day 21–30: Cross-sell. Based on what they bought, what’s the most logical next product? Use Klaviyo’s product recommendation blocks for dynamic suggestions. This email should feel like a recommendation from someone who knows what they bought, not a generic promotional email.

Email 5 — Day 35–45: Replenishment trigger (for consumables) or loyalty/referral ask. “You’re probably running low” for 30-day consumables. For durable goods, introduce your referral program or loyalty tier.

Benchmark: A properly built post-purchase sequence increases 90-day repeat purchase rate by 20–35%.

Flow 5: Browse Abandonment

What it is: Triggered when a known subscriber (someone in your Klaviyo list) views a product page 1–3 times without adding to cart or purchasing.

Revenue contribution: 4–8% of total email revenue for apparel, home goods, and beauty — often the most overlooked flow.

Setup in Klaviyo: This requires the Klaviyo Shopify integration to be properly tracking viewed product events. Confirm your integration is passing Viewed Product events before building this flow.

The architecture (2 emails):

Email 1 — 4–12 hours after browse: Product spotlight email. Show the exact product they viewed, with full imagery, price, key features, and social proof (star rating, number of reviews). This is not an aggressive push — it’s a “we noticed you were interested” touch.

Email 2 — 24–48 hours later: Overcome consideration barriers. For high-consideration products (above $100), address common objections: sizing/fit, return policy, reviews from people in similar situations. For lower-ticket items, a brief “still thinking?” reminder with a social proof-heavy angle works well.

Key filter: Exclude anyone who has added the product to cart (they should be in the cart abandonment flow, not this one).

Benchmark: Browse abandonment flows generate a 2–6% conversion rate — lower than cart abandonment, but high-volume because browse events are frequent.

Flow 6: Win-Back (Lapsed Customer)

What it is: Triggered when a customer hasn’t purchased in a defined window — typically 90, 120, or 180 days, depending on your average purchase frequency.

Why this flow is critical: Reactivating a lapsed customer costs 5–7x less than acquiring a new one. The win-back flow is how you systematically recover revenue that would otherwise be lost.

Setting the right trigger window: Your trigger window should be based on your actual purchase frequency data. Pull your average days between first and second purchase in Klaviyo’s analytics. If your average customer purchases every 45 days, a 90-day win-back window is right. If your category is seasonal (e.g., outdoor gear), adjust accordingly.

The architecture (3–4 emails):

Email 1 — “We miss you”: Warm reengagement. No offer yet. Simply acknowledge their absence and highlight what’s new — new products, new reviews, updates to your brand. Subject line: “It’s been a while — here’s what you missed.”

Email 2 — 5–7 days later: Incentive offer: Now introduce an offer — but make it feel earned and exclusive. “Because you’ve shopped with us before, here’s 15% off your next order.” Create genuine urgency with a 72-hour expiry.

Email 3 — 24–48 hours before offer expires: Reminder: Short, urgency-focused. “Your exclusive offer expires in 24 hours.” One CTA, no distractions.

Email 4 (Optional) — 7–14 days after offer expires: Final check-in: If they still haven’t purchased, a final low-pressure touch. “We’ll miss you — but your preferences are saved if you ever return.” Include a way to update email preferences to reduce frequency (this recovers some subscribers who were unengaging due to volume, not disinterest).

Benchmark: Win-back flows recover 8–15% of lapsed customers when properly sequenced.

Flow 7: Sunset (List Hygiene Automation)

What it is: Triggered when a subscriber has not opened, clicked, or purchased within a defined window (typically 90–180 days). The goal is to either reactivate them one final time, or cleanly suppress them to protect deliverability.

Why it belongs in your core 7: Most brands handle list hygiene manually and irregularly. Automating the sunset process means your list is always at optimal health — continuously removing dead weight without you having to remember to run hygiene passes.

The architecture (2–3 emails):

Email 1 — “Are you still there?”: Direct, transparent subject line: “We want to make sure we’re not bothering you.” Or: “Should we keep sending you emails?” This honesty works — it generates real engagement from subscribers who are dormant but not gone, and gives you clean data on who genuinely doesn’t want to hear from you.

Email 2 — 7 days later: Final chance to re-engage. “This is the last email we’ll send unless you’d like to stay on our list.” Include a simple one-click “Keep me subscribed” CTA. This recovers 5–15% of dormant subscribers who simply haven’t engaged but don’t want to leave.

Action after flow completion: Anyone who doesn’t engage with either email gets suppressed automatically using a Klaviyo flow action. Don’t delete them — suppress. You can always reactivate if they purchase through another channel.

The deliverability impact: Brands that implement automated sunset flows see open rates improve 8–15 percentage points within 60 days as list quality increases. This improves inbox placement for all sends.

How These 7 Flows Work Together

The flows above aren’t independent — they work as a system. A new subscriber enters the welcome series. If they browse without buying, they enter browse abandonment. If they add to cart without buying, they’re moved to cart abandonment. After purchase, they’re in the post-purchase flow. If they lapse, win-back triggers. If they go completely dark, sunset removes them.

When all 7 are live and properly configured, this system runs autonomously and compounds over time. Every new subscriber, purchaser, and lapsed customer is touched at the right moment with the right message.

At Excelohunt, the first thing we do when onboarding a new Shopify client is audit which of these 7 flows exist, whether they’re triggering correctly, and whether the segmentation logic is sound. In most cases, building or rebuilding these flows within the first 60 days generates 25–40% more monthly email revenue without changing a single campaign.

The math is straightforward: if you’re doing $200K per month in revenue and email accounts for 20% ($40K), bringing flows up to proper coverage could add $15K–$20K per month in automated revenue. Permanently, without ongoing effort.
