Klaviyo Flows That Actually Move Revenue (2026 Edition)

Most ecommerce brands have Klaviyo installed and a handful of flows set up. Most of those flows are incomplete, poorly timed, or mis-segmented in ways that leak revenue every single day. When we audit Klaviyo accounts, the email layer is usually contributing 12 to 18 percent of total revenue. A well-built system contributes 25 to 35 percent. That delta is real money.

Here are the 8 flows every ecom brand should have live, built correctly.

1. Welcome Series (the most undervalued flow)

Trigger: Subscribed to list (via popup, embedded form, or checkout opt-in).

Structure: 5 to 7 emails across 21 days.

Email 1 (immediate): Deliver the signup offer if one was promised. Introduce the brand in one paragraph. Soft CTA to shop.

Email 2 (day 1): Story. Founder story, or the origin story of your flagship product. No sell.

Email 3 (day 3): Bestsellers. Show 4 to 6 products with clear reason-to-buy copy.

Email 4 (day 5): Social proof. Reviews, press mentions, customer UGC. Soft CTA.

Email 5 (day 8): Use case or scenario email. "How our customers use this." Educational.

Email 6 (day 14): Reminder of the signup offer if not yet used. Urgency with a deadline if appropriate.

Email 7 (day 21): Graduation email. "Thanks for being on the list." Invite to follow on social.

Typical revenue contribution: 5 to 8 percent of total revenue, if the list grows steadily.

2. Abandoned Cart (3 emails, not 1)

Trigger: Added to cart, did not complete checkout in 4 hours.

Email 1 (4 hours post-abandonment): Friendly reminder with cart contents. "We saved your bag." No discount yet.

Email 2 (24 hours): Light nudge. Address a likely objection (shipping cost, return policy, sizing). Show reviews or trust signals.

Email 3 (48 hours): Offer. 10 to 15 percent off if the cart total is above your average order value. Below AOV, often better to offer free shipping instead.

Typical revenue recovery: 8 to 12 percent of abandoning sessions.

Most accounts we audit have one abandoned cart email and stop. Adding emails 2 and 3 typically doubles or triples recovered revenue.

3. Abandoned Checkout (tighter than cart)

Trigger: Started checkout, did not complete in 2 hours.

Structure: 2 emails, tighter timing.

Email 1 (2 hours): Reminder with cart contents. No discount.

Email 2 (24 hours): Address common last-mile objections (delivery time, payment methods, sizing). Discount only if cart above AOV.

Typical recovery: 15 to 20 percent of abandoning checkouts (higher than cart because intent is higher).

4. Browse Abandonment (subtle but effective)

Trigger: Viewed a product 3+ times in 14 days, did not add to cart.

Structure: 1 to 2 emails.

Email 1 (2 days after last view): "Still thinking about this?" Show the product, include a review or two, soft CTA.

Email 2 (optional, 5 days): Show the product again with a related product or two. No discount.

Typical revenue contribution: 1 to 3 percent. Small but almost entirely incremental (revenue you would not otherwise capture).

5. Post-Purchase (where repeat revenue lives)

Trigger: Order placed.

Structure: 5 emails across 60 days.

Email 1 (1 day after delivery): Thank you, care instructions or onboarding tip, invitation to follow on social.

Email 2 (7 days after delivery): Review request. Offer nothing in exchange, just ask. Include a preview of what other customers wrote.

Email 3 (14 days after delivery): Cross-sell based on the product they bought. If they bought a candle, show candle accessories. If they bought a dress, show shoes or a matching bag.

Email 4 (30 days): Loyalty or referral program invitation, if you have one. Otherwise, user-generated content callout ("share on Instagram and tag us").

Email 5 (60 days): Replenishment or repeat-purchase nudge. "Time to restock?" for consumables. "New arrivals" for non-consumables.

Typical revenue contribution: 6 to 10 percent of total revenue if you have repeat-purchase behavior (most categories do).

6. Win-Back (for lapsing customers)

Trigger: Has purchased, has not engaged in 90 to 180 days (depending on category).

Structure: 3 emails across 14 days.

Email 1: "We miss you." Show what has launched since their last order.

Email 2 (7 days later): Offer. 15 to 20 percent off. Real discount, not a fake one.

Email 3 (14 days): Last chance framing. Personal, one-to-one tone.

Typical reactivation rate: 8 to 15 percent of lapsing customers buy again within 30 days.

7. Sunset Flow (protects your deliverability)

Trigger: Has not opened or clicked in 120 to 180 days.

Structure: 2 emails, then unsubscribe.

Email 1: "Are you still interested?" Simple yes or no CTA. Yes keeps them, no or no action unsubscribes them.

Email 2 (7 days later): Final confirmation. No response after this removes them from active sends.

Sunset flows seem counterproductive because they reduce your list size. In reality, they dramatically improve deliverability because inactive subscribers hurt your sender reputation. Counter-intuitive but correct.

8. Back in Stock (catch latent demand)

Trigger: Signed up for back-in-stock notification on a specific product.

Structure: 1 email.

Email (immediate when restocked): "It is back." Product image, clear CTA. Ideally with a 24-hour urgency ("Back in stock, selling fast").

Typical conversion rate: 35 to 50 percent of back-in-stock notifications convert. Highest-converting email type in any ecom system.

What all of these share

Every flow above follows three principles.

Time-based, not drip-based. Trigger based on behavior (cart abandoned, order placed), not a fixed interval. This lets the email show up when the subscriber is actually thinking about you.

Light on discounts until necessary. First emails in every flow should be value-led, not discount-led. Save the discount for the last 30 percent of the flow if needed. Brands that discount in email 1 train subscribers to wait for the discount.

Mobile-first design. 65 to 75 percent of opens are on mobile. Design for a single-column layout, large touch targets, legible 16px+ body text.

What not to do

Do not send the same flow to everyone. Segment at minimum by active vs lapsing, and ideally by purchase category affinity. A candle buyer and a home decor buyer should see different bestsellers emails.

Do not send more than 3 emails per week to any segment. You will burn the list. Exception: VIP segments who have opted into more frequent communication.

Do not forget SMS. For brands over $100K per month in revenue, SMS handling post-purchase and abandoned cart can add another 3 to 5 percent to revenue. Volume must be tight (2 to 4 per month max) or you will get blocked.

Realistic timeline to ship these

Starting from zero, here is how long it takes to build out the 8-flow system.

Week 1: Welcome series and abandoned cart. These two alone usually add 10+ percent to revenue.

Weeks 2 to 3: Abandoned checkout, back in stock, sunset.

Weeks 4 to 6: Post-purchase series, win-back, browse abandonment.

Months 2 to 3: Optimization, segmentation refinement, A/B tests on subject lines and send times.

Ongoing: monthly campaign calendar that layers on top of the flows.
