The difference between an email program generating 12% of revenue and one generating 42% is almost always the same thing: automated flows.

Campaigns are how you communicate. Flows are how you convert. They fire at the exact moment a subscriber is most likely to act, and they run without you. According to Omnisend’s 2024 data, automated emails drove 37% of all email-generated sales despite making up just 2% of email volume, and flows generate 30× more revenue per recipient than campaigns ($3.65 vs $0.11 RPR, per Klaviyo).

These are the ten flows we build for every new client. Brands that have all ten consistently hit 35–50% email attribution. Brands missing five or six of them are typically stuck under 20%.


1. Welcome Series

Trigger: New subscriber joins list (before first purchase)

Goal: Build trust, introduce the brand, earn the first purchase

Length: 4–6 emails over 10–14 days

The welcome series is your highest-RPR (revenue per recipient) flow. A new subscriber has their highest attention and curiosity in the first 48 hours. Most brands waste this window with a single “Here’s your 10% off” email.

A strong welcome series educates before it sells. Email 1 delivers the promise (discount, lead magnet, or brand intro). Emails 2–4 build the case: founder story, social proof, product education. Email 5 is the conversion push, and Email 6 is a last-chance offer for anyone who hasn’t bought.

Benchmark: Klaviyo 2025 data shows an average 51% open rate and $3.34 RPR (for stores with AOV $100–$200), with top performers reaching nearly 10% placed order rate. Series conversion to first purchase typically runs 15–25%.


2. Abandoned Cart

Trigger: Item added to cart, checkout not completed

Goal: Recover the lost purchase

Length: 3 emails: 1 hour, 24 hours, 72 hours

Abandoned cart is the most universally known flow and often the worst implemented. Most brands send one email with a product image and a “You left something behind” subject line.

Three emails significantly outperform one. The timing matters: the 1-hour email catches impulsive abandoners. The 24-hour email addresses hesitation with social proof. The 72-hour email applies a reason to buy now, usually urgency or a modest incentive.

Benchmark: Klaviyo’s analysis of 143,000 abandoned cart flows shows an average 50.5% open rate and $3.65 RPR, making this the single highest-RPR automated flow in ecommerce. Cart recovery rates typically run 8–15%.


3. Browse Abandonment

Trigger: Subscriber views a product page but doesn’t add to cart

Goal: Re-engage the consideration stage

Length: 2 emails: 4 hours, 24 hours

Most brands skip this one because the intent signal is weaker. That’s a mistake. Browse abandonment catches people earlier in the funnel and, at scale, generates meaningful incremental revenue, often 5–10% of total flow revenue.

Keep these short. A product image, a brief piece of social proof, and a single CTA.


4. Post-Purchase Onboarding

Trigger: First purchase completed

Goal: Deliver value, set expectations, begin building loyalty

Length: 3–5 emails over 14–21 days

The post-purchase window is when buyer’s remorse peaks. A well-designed onboarding sequence reduces refunds, increases product satisfaction, and dramatically improves repeat purchase rates.

Email 1 confirms the order and sets shipping expectations. Emails 2–3 deliver product usage guidance or education. Email 4 surfaces complementary products. Email 5 asks for a review.

Brands with a strong post-purchase sequence consistently see 15–25% higher 90-day LTV compared to those without.


5. Second Purchase Flow

Trigger: First purchase made, no second purchase after X days (typically 21–30 days depending on product)

Goal: Convert one-time buyers into repeat customers

Length: 2–3 emails

The economics of email marketing depend on repeat purchase rate. A one-time buyer has a fraction of the LTV of a two-time buyer. This flow is one of the highest-ROI you can build.

Focus on product education, complementary recommendations, and social proof from customers who use multiple products. Don’t lead with a discount. Test organic first.


6. Replenishment / Reorder Reminders

Trigger: Expected replenishment date based on purchase history

Goal: Prompt reorder before the customer runs out (and potentially buys from a competitor)

Length: 2 emails: “running low” and “it’s time”

For products with a predictable consumption cycle (consumables, skincare, supplements, household goods), this flow can generate more revenue per subscriber than any other automation. Replenishment emails have a 53.6% click-to-open rate, the highest of any email type in ecommerce (ConvertCart). Timing is everything: send too early and it’s irrelevant, send too late and they’ve already reordered elsewhere.

Calculate average purchase intervals from your order data in Shopify and configure accordingly. Most brands find 85–90% of their best interval in the first reminder.


7. Subscription Save / Churn Deflection

Trigger: Subscription cancellation initiated or subscription pause requested

Goal: Retain the subscriber

Length: 1–2 emails with a pause or skip option surfaced prominently

If you have a subscription or membership model, this flow pays for itself many times over. The key is offering the right alternatives (pause, skip, or swap product) before the subscriber completes the cancellation.

An offer in the cancellation flow should only appear if pause/skip doesn’t resolve the objection. Discounting everyone who tries to cancel trains subscribers to cancel to get a deal.


8. Win-Back

Trigger: No purchase in 90–180 days (calibrate to your average purchase frequency)

Goal: Re-engage lapsed customers before they churn permanently

Length: 3 emails: re-engagement, incentive, last chance

Lapsed customers are cheaper to reactivate than new customers are to acquire. A win-back flow that converts even 5% of lapsed buyers pays significant dividends at scale.

Email 1 acknowledges the absence with a soft re-engagement angle. Email 2 introduces an incentive. Email 3 is a last chance. Be explicit that this is the final email.

Anyone who doesn’t re-engage after the win-back sequence should be suppressed from campaign sends to protect deliverability.


9. VIP / High-LTV Customer Flow

Trigger: Subscriber reaches LTV threshold (e.g. 3+ purchases or $500+ spent)

Goal: Reward loyalty, deepen brand affinity, increase frequency

Length: Ongoing: exclusive content, early access, personalised offers

VIP customers are your best asset. They already buy, they already trust you, and they have the highest probability of increasing AOV if treated well. Most brands do nothing special for them beyond the standard campaign schedule.

A VIP flow surfaces early access to new products, exclusive content, personal notes from the founder, and loyalty-only offers. It doesn’t need to be complex. It needs to make the subscriber feel known.


10. Sunset / Suppression Flow

Trigger: Subscriber has not opened any email in 120–180 days

Goal: Get one final re-engagement before permanent suppression

Length: 3 emails with subject lines referencing inactivity explicitly

This is the flow nobody wants to build, but it’s critical for deliverability. Sending consistently to unengaged subscribers tanks your sender reputation with every major inbox provider.

The sunset flow makes one last attempt with a transparent subject line: “Should we keep in touch?” If they don’t re-engage, suppress them. Your deliverability (and therefore all your other flows) will improve.


Where to Start

If you’re missing more than three of these, start with Welcome, Abandoned Cart, and Post-Purchase. Those three alone typically account for 60–70% of flow revenue, and abandoned cart, welcome, and browse abandonment emails account for 87% of all automated orders (Omnisend 2024). Build the rest systematically over the following 90 days.
