If you’re running a DTC ecommerce brand and your email is mostly one-off campaigns, you’re leaving money on the table every single day.
Automated email flows, sequences that trigger based on customer behavior, are the engine behind the best-performing email programs in e-commerce. They run in the background 24/7, and when built correctly, they can generate 40-60% of your total email revenue without you touching a thing.
Why Flows Outperform Campaigns
The difference between a campaign and a flow is timing. A campaign goes out to a broad list on a date you choose. A flow goes out to the right person at the right moment — when they just subscribed, abandoned a cart, or went 60 days without buying.
That context is everything. Klaviyo data shows automated flows generate dramatically higher revenue per recipient than standard campaigns, because they arrive at a moment of actual intent or need. The content is relevant by default.
The top-performing brands on Klaviyo have at least 10 flows live. If you have fewer than five, that’s your starting point.
Here are the five you absolutely cannot afford to skip.
Flow 1: The Welcome Series
What it is
Triggered when someone joins your email list, the welcome series is your brand’s first real conversation with a subscriber. Most brands treat it like a formality — “Hi, here’s your discount.” That’s a missed opportunity.
What it should accomplish
A strong welcome series does three things: remove doubt about who you are and what you sell, build enough trust to earn a first purchase, and create momentum toward an easy next step.
If someone signed up via a pop-up but hasn’t bought yet, your welcome flow needs to work harder. If they signed up after a purchase, the messaging should be completely different — skip the “who we are” content and move straight to building the relationship.
How to optimize it
Email 1 should deliver on the promise (discount, freebie, etc.) immediately, then introduce your brand story briefly.
Email 2 (1-2 days later) should feature your bestsellers with strong social proof, reviews, before/afters, and UGC.
Email 3 (3-4 days later) should address the most common objections. What stops people from buying? Answer it here.
Email 4 (6-7 days later, if still no purchase) should create urgency: discount expiry, limited stock, or a founder’s note.
Flow 2: The Abandoned Cart Series
What it is
Someone adds a product to their cart but leaves without completing the purchase. The abandoned cart flow is triggered by that exit. It’s one of the highest-revenue flows in any ecommerce email program.
What it should accomplish
The goal is simple: bring the customer back and remove whatever stopped them from buying. That could be price hesitation, distraction, shipping costs, or doubt about the product.
How to optimize it
Send Email 1 within 1-2 hours of abandonment. Keep it short: remind them what’s in their cart, include the product image, and make it easy to come back.
Send Email 2 within 24 hours. This is where you add trust, reviews for the specific product they were looking at, a guarantee, or an FAQ that addresses common hesitations.
Send Email 3 at 48-72 hours. If they still haven’t bought, this is the time to add an incentive (a small discount or free shipping) and create a sense of urgency.
Personalize with the actual product name and image. Generic abandoned cart emails consistently underperform.
Suppress customers who purchased through another channel after abandoning.
Flow 3: The Post-Purchase Series
What it is
Triggered when someone completes their first order, the post-purchase flow is the most underused lever in DTC email marketing. Most brands send an order confirmation and go quiet until the next campaign. That’s a mistake.
What it should accomplish
The goal of a post-purchase flow is to turn a first-time buyer into a repeat customer. This is where LTV is built or lost. A great post-purchase sequence does four things: manages expectations around delivery, ensures the customer gets value from what they bought, collects reviews, and creates a natural path to a second purchase.
How to optimize it
Day 1-2: Order confirmation + excitement building. Set delivery expectations and build anticipation. Not just transactional, inject some personality.
Day 3-5: “Your order is on its way.” Include usage tips, how-to content, or what to expect when the product arrives.
Day 7-10 (after expected delivery): Ask for a review. Make it dead simple. This is also a great moment to introduce a complementary product.
Day 14-21: The cross-sell. Based on what they bought, recommend what naturally comes next. Use Klaviyo’s catalog integration for dynamic product recommendations.
Day 45-60: A gentle win-back trigger if they haven’t bought again, or a birthday email if you have the data.
The brands that dominate in LTV aren’t outspending competitors on ads. They’re outperforming them in the post-purchase experience.
Flow 4: The Browse Abandonment Flow
What it is
Different from cart abandonment, browse abandonment fires when someone views a product page or category but leaves without adding anything to their cart. The intent signal is weaker, but the volume is much higher.
What it should accomplish
The goal is to re-engage while the product is still top-of-mind, answer any questions the shopper might have, and give them a reason to come back and look again.
How to optimize it
Keep it to 1-2 emails maximum. Over-following up on a browse event feels intrusive.
Email 1 (3-4 hours after browsing): Feature the product they viewed with a clean, minimal design. Include a strong review or a key benefit callout.
Email 2 (24 hours later, optional): Introduce a social proof angle, “Other customers who looked at this also loved...” or a bestseller alongside the product they viewed.
Suppress anyone who has since added to the cart or purchased, they’ve moved further down the funnel.
Flow 5: The Win-Back (Re-Engagement) Flow
What it is
Every list has customers who bought once and disappeared. The win-back flow targets people who haven’t purchased in 60-120 days (depending on your average repurchase window) and tries to bring them back before they’re gone for good.
What it should accomplish
Win-back flows serve two purposes: recovering lapsed customers who still have purchase intent, and cleaning your list of people who are truly gone (protecting your deliverability in the process).
How to optimize it
Timing matters: Set your win-back trigger based on your average repurchase cycle. A supplements brand re-orders every 30 days, a 45-day win-back makes sense. A fashion brand might wait 90-120 days.
Email 1: A simple, human “we miss you” message. Remind them what they bought and offer something relevant to their purchase history.
Email 2 (7 days later): An incentive. A modest discount or free shipping is usually enough to tip the decision.
Email 3 (7 days after that): A “last chance” email. Tell them you’re removing them from your VIP list, or their discount is expiring. This creates action or a clean break.
After 3 emails with no engagement: suppress from campaigns. Protecting deliverability is worth more than holding onto a dead contact.
The Big Picture: Flows Are a System, Not a Checklist
These five flows aren’t five separate tactics. They work together as a system, catching customers at every critical moment in their journey and moving them toward a deeper relationship with your brand.
Getting all five live and optimized is typically what takes a brand from email generating <10% of revenue to 25-35%. The setup investment is real, but the payoff is ongoing and compounding.
