I've audited over 350 DTC and CPG brands. One pattern shows up in virtually every brand stuck under £20K a month: email is being used almost entirely as a broadcast channel. Weekly newsletters to the full list. Maybe a sale announcement. Zero automation.
Meanwhile, the data from Klaviyo's 2026 benchmark report, covering over 183,000 brands, is unambiguous. Email flows, which are automated sequences triggered by behaviour rather than sent on a schedule, generate nearly 41% of total email revenue from just 5.3% of total sends. The average revenue per recipient from flows is 18 times higher than from campaigns.
That gap between what most brands do and what the data says works is where revenue leaks. Building the five flows below is the single fastest way to close it.
Why flows outperform campaigns every time
A campaign is sent to a list at a time you choose. The relevance is determined by segmentation and timing, and if your segmentation is imprecise, the email lands at the wrong moment for most recipients. Even a well-crafted campaign to a well-segmented list is working against the reality that people buy when they're ready, not when you send.
A flow sends the right email at the moment a specific behaviour indicates intent. Someone just signed up: they're at peak curiosity. Someone added to cart but didn't buy: they have a specific objection. Someone bought three weeks ago: they're approaching the repurchase window. Each of these moments has a different message that converts. Flows deliver that message automatically, in real time, without any human intervention.
This is also why flows have dramatically higher deliverability. Emails sent to engaged recipients at high-intent moments generate strong open and click rates, which improves your sender reputation, which improves inbox placement for everything else you send.
The five flows that move the needle
These are not the only flows worth building. They are the five that should exist before anything else, and the five most commonly missing when I run an audit.
The welcome series
Benchmark: 1.97% placed order rate. Top 10% convert at 9.89%.
The welcome series is the most important flow a DTC brand can build, and the most commonly underbuilt. It triggers when someone joins your list, which is the highest-intent moment in the subscriber lifecycle. They just raised their hand and said they're interested. If you respond with a single discount email and nothing else, you're leaving a significant portion of that intent on the table.
A properly built welcome series is three to five emails sent over seven to ten days. The first email sends immediately, covers who you are and why it matters, and includes your best first-purchase offer. The second email, sent 24 to 48 hours later, handles the most common objections: Is this right for me? Is it worth the price? Can I trust this brand? Emails three through five deepen the social proof, tell the origin story in more depth, and create a genuine urgency around the initial offer before it expires.
Klaviyo's benchmark data shows companies with an average order size of £100 to £200 generate an average revenue per recipient of £3.34 from welcome series alone. Multiply that by your monthly signup rate and you'll see immediately how much you're leaving on the table if this flow doesn't exist.
The abandoned cart flow
Benchmark: 3-email sequence recovers 5-15% of abandoned carts.
Cart abandonment rates for DTC ecommerce typically sit between 70% and 80%. That means for every 100 people who add to cart, 70 to 80 leave without buying. The abandoned cart flow exists to recover a meaningful portion of that group before the intent goes cold.
The flow should be three emails. The first sends within one hour of abandonment and is the most important. Research consistently shows that the first hour has by far the highest conversion rate: the customer is still in the decision window. This email should be simple, direct, and free of excessive design. It exists to remind and remove friction, not to present a brand experience.
The second email sends 24 hours later and introduces social proof: specific reviews, before and after evidence, or a customer story relevant to the product they abandoned. The third sends at 72 hours and introduces a time-limited incentive if margin allows. Not every brand needs to discount: urgency through limited stock or offer expiry can achieve the same effect without eroding margin.
The post-purchase sequence
Benchmark: 3.2x higher LTV from customers who receive a structured post-purchase flow.
Most brands treat the first purchase as the end of the conversion. It isn't. It's the beginning of the relationship, and the period immediately after purchase is the highest-engagement window you will ever have with that customer. They're excited, they're paying attention, and they're receptive. If you send nothing until a reorder reminder six weeks later, you've missed the most valuable window for deepening the relationship.
The post-purchase sequence should start with a confirmation email that goes beyond order logistics. Include what to expect, how to use the product for best results, and a specific outcome to look for. Then follow up within five to seven days to check in, pre-empt any friction, and add value through content or community. Around day 14, introduce a relevant complementary product or subscription option. Around day 30, request a review with a specific, low-friction ask.
This sequence does three things simultaneously: it reduces returns and complaints, it increases repeat purchase rate, and it generates the reviews that fuel future acquisition. It's the highest-leverage email flow for brands selling consumables, health and wellness products, or anything with a natural repurchase cycle.
The browse abandonment flow
Benchmark: 2-3% conversion rate from browse abandonment triggers.
Browse abandonment is the underestimated sibling of cart abandonment. When a subscriber on your list views a product page but does not add to cart, they've shown intent. They're interested enough to click through to the product but not yet ready to commit. A browse abandonment flow sends a targeted email shortly after, while the interest is still live.
This flow requires Klaviyo or a similar platform with site tracking enabled, so the system knows which products a specific subscriber has viewed. Once that's in place, the trigger logic is straightforward: subscriber views product page, does not add to cart within two hours, receives a single targeted email.
The email should feature the specific product they viewed, three to five tight social proof signals, and a single clear call to action. Keep it short. The goal is to remove a specific objection or create a specific reason to return. This flow typically sits at a 2% to 3% conversion rate and requires zero ongoing maintenance once built. For brands with high traffic and an active email list, it can represent a meaningful revenue line with no additional acquisition spend.
The win-back flow
Benchmark: 8-15% of lapsed customers reactivated with a structured win-back sequence.
A win-back flow targets customers who have previously purchased but have not returned within your typical repurchase window. For most DTC brands this is 60 to 90 days. The goal is dual: reactivate a portion of the lapsed segment and, for those who do not re-engage, clean them off the active list before they hurt deliverability.
The flow should be four to five emails. The first acknowledges the lapse without being sycophantic. It should be direct and human, not "We miss you!" Copy that treats the subscriber like an adult performs significantly better than generic win-back language. Email two introduces a specific reason to return: a new product, a formulation improvement, a compelling bundle, or a time-limited offer. Emails three and four create escalating urgency. Email five is a breakup email that states clearly the subscriber will be removed from the list if they don't click, and means it.
The win-back flow is also one of the most important list hygiene tools you have. A clean, engaged list of 5,000 subscribers will outperform a bloated disengaged list of 50,000 every single time. Deliverability is directly tied to engagement rates, and if a significant portion of your list hasn't opened in 180 days, your inbox placement for everyone else suffers.
The order of build matters
If you're starting from zero, don't try to build all five at once. The welcome series and abandoned cart flow have the highest immediate revenue impact and should go live first. Between them, they capture intent at both ends of the pre-purchase journey.
Post-purchase comes third, because protecting and growing the customers you've already acquired is the fastest way to improve LTV and reduce the pressure on acquisition costs. Browse abandonment is fourth, requiring site tracking to be set up cleanly before it can trigger accurately. Win-back comes fifth, because you need a pool of lapsed customers and historical data before this flow generates meaningful volume.
The typical timeline, if you're building from scratch with focused effort, is six to eight weeks to have all five flows live and performing. Most of the work is in the welcome series and post-purchase content. The mechanics of the other three are simpler once the infrastructure is set up.
What this actually looks like in practice
Bottled Baking Co came to us at £5K a month with email generating under 5% of revenue. There were no automated flows. We built a four-email welcome series, a three-email abandoned cart sequence, and a post-purchase flow. Email contribution moved from 5% to 31% of total revenue within 45 days. Total revenue moved from £5K to over £50K a month within 90 days, supported by flow revenue running continuously in the background without any ongoing effort.
This is not unusual. The reason most brands don't have these flows isn't that they're complex. It's that nobody has sat down and built them. They're one of the few genuinely permanent improvements you can make to a growth engine: once they're live, they generate revenue every day without any marginal spend.
A properly built flow stack is also one of the most powerful levers for improving the economics of paid media. When email is recovering abandoned carts and retaining customers, your effective ROAS on acquisition spend improves because you're extracting more lifetime value from every customer you bring in. The flows effectively subsidise acquisition.
Platform, deliverability, and one technical note
All five of these flows can be built on Klaviyo, which remains the platform of choice for Shopify brands because of its native integration depth, behavioural triggers, and segmentation capabilities. The browse abandonment flow in particular requires a platform with reliable site tracking, and Klaviyo's Shopify integration handles this without additional setup.
One technical note on open rates: since Apple's Mail Privacy Protection launched in 2021, reported open rates are artificially inflated for Apple Mail users. Platform-reported open rates may run 10 to 15 percentage points above actual opens. Use click rate and conversion rate as your primary performance indicators for flows. These are not affected by MPP and give an accurate read on engagement.
For benchmarking, Klaviyo's 2026 industry data shows that email as a channel converts at 2.6% to 10.3% depending on list quality and flow maturity, with email traffic converting at 5x the rate of social media traffic. If your email is converting below 3%, the flows above are almost always the primary constraint.

Frequently asked questions
What is an email flow for ecommerce?
An email flow is an automated sequence of emails triggered by a specific customer behaviour, such as signing up to a list, abandoning a cart, or completing a purchase. Unlike broadcast campaigns sent to your full list, flows are triggered in real time and personalised to where the subscriber is in the customer journey. This is why they consistently outperform campaigns on a per-recipient basis.
What are the most important email flows for DTC brands?
The five most important flows for DTC brands are: the welcome series, the abandoned cart flow, the post-purchase sequence, the browse abandonment flow, and the win-back flow. Together these five flows can move email from under 10% of total revenue to 25-40% within 60 to 90 days when properly configured.
How much revenue should email flows generate?
According to Klaviyo's benchmark data, email flows generate nearly 41% of total email revenue from just 5.3% of total sends. The average revenue per recipient for flows is 18 times higher than for broadcast campaigns. For most DTC brands, flows alone should represent 20-30% of total revenue once properly built out.
How many emails should be in a welcome series?
A welcome series should be three to five emails sent over seven to ten days. The first email sends immediately and should focus on brand story and a compelling first offer. The second email, sent 24 to 48 hours later, addresses the most common objections and reinforces the purchase case. Emails three to five deepen the relationship, showcase social proof, and create urgency around the initial offer before it expires.
What is the conversion rate for abandoned cart emails?
According to Klaviyo's 2026 benchmark data, a three-email abandoned cart sequence recovers between 5% and 15% of carts that would otherwise be lost. A single abandoned cart email recovers significantly fewer. The first email, sent within one hour, captures the highest conversion rate. Subsequent emails sent at 24 and 72 hours recover a further portion of the remainder.
When should I use a win-back flow?
A win-back flow should trigger when a customer who has previously purchased has not returned within your typical repurchase window. For most DTC brands this is 60 to 90 days. The flow should acknowledge the lapse, offer a specific reason to return, and create a genuine time-limited incentive. Win-back flows also serve a list hygiene function: subscribers who do not re-engage after four to five win-back emails should be suppressed to protect deliverability.
