Most ecommerce brands either have no flows at all, or they have a basic three-email welcome series and an abandoned cart reminder that fires at 9am every morning regardless of when the customer actually left. Neither of these is a system. Neither of these is generating anywhere near the revenue your list is capable of producing.

Here is exactly what a properly built flow architecture looks like for a DTC brand doing $50,000/month or more, and why each one matters.

The Five Flows Every DTC Brand Needs Running Before Anything Else

1. Welcome Series

Your welcome series is the most important relationship-building tool in your entire email programme. It is the first thing a new subscriber experiences from your brand, and it sets every expectation they will have about your emails going forward.

A well-built welcome series does three things. It introduces your brand with personality and clarity. It showcases your best products in a way that feels helpful rather than pushy. And it converts new subscribers into first-time buyers within the first 48 to 72 hours of them joining your list.

Industry data puts average welcome series open rates at 50 to 60%, which is significantly higher than any campaign email will ever achieve. That attention is a window. A badly built welcome series wastes it on generic "thanks for signing up" copy and a single discount code. A well-built one uses it to create a customer.

At Retain Marketing, we refresh welcome flows every 60 to 75 days. Not because the fundamentals change, but because a fresh series consistently outperforms a stale one. Most agencies build it once and never touch it again. That is a mistake that costs real revenue over time.

The welcome series should be a minimum of 4 to 6 emails. Not three. Not one. Four to six, spaced based on behaviour and engagement rather than fixed send times.

2. Abandoned Cart Flow

This is your highest-converting flow and the fastest path to immediate revenue from any email programme.

A customer who adds a product to their cart and then leaves is not a lost sale. They are a high-intent buyer who got distracted, had a question, or needed a small push. Your abandoned cart flow exists to provide that push.

The average abandoned cart flow converts at 3.3% of recipients, with top performers hitting 7 to 8%. The average revenue per recipient is around $3.65. For a brand receiving 500 abandoned carts per month, a well-built flow is generating $1,825 on the low end, passively, every single month.

What most brands get wrong: a single reminder email 24 hours later with "You forgot something!" as the subject line. What actually works: a sequence of 3 emails spaced across 24 to 48 hours, combining urgency, social proof, product education, and a final incentive for the most resistant customers. And critically, these emails should fire based on hours elapsed since abandonment, not at a fixed time of day.

We also integrate SMS at the right points within this flow for clients who have collected mobile numbers. An SMS immediately upon cart abandonment followed by an email if there is still no conversion dramatically outperforms either channel running independently.

3. Browse Abandonment Flow

This one is consistently underbuilt or completely missing from most ecommerce accounts, and it is one of the highest-leverage flows you can add to an existing programme.

Browse abandonment targets customers who have visited a product page but did not add anything to their cart. They showed intent. They looked. They just did not take the next step.

These customers are warmer than you might think. They are on your list, they visited a specific product, and they left without buying. A well-timed browse abandonment email reconnects them with exactly what they were looking at, adds context about the product, and gives them a reason to come back.

The open rates on browse abandonment flows tend to be strong because the emails are genuinely relevant to what the customer was just doing. Relevance is the single most powerful driver of email engagement, and browse abandonment gets relevance right by definition.

4. Post-Purchase Flow

Most brands treat the post-purchase period as dead air. The customer bought, the order confirmation went out, and then nothing happens until the next campaign lands in their inbox two weeks later.

This is one of the most expensive missed opportunities in ecommerce email.

The post-purchase window is when your customer is at peak satisfaction with your brand. They just bought something they wanted. They are engaged, they are paying attention, and they are open to hearing from you. This is exactly the right moment to introduce complementary products, invite them to leave a review, deepen their relationship with your brand story, and begin converting a one-time buyer into a repeat customer.

A well-built post-purchase flow increases repeat purchase rates meaningfully. For Jubilee Scents, introducing a structured post-purchase sequence was one of the key contributors to the 34% increase in repeat purchases we achieved within 90 days. The emails did not feel like upselling. They felt like a continuation of the relationship.

The post-purchase flow should include at minimum: a branded order confirmation, a delivery update, a product education email, a review request at the right moment, and a cross-sell or upsell sequence tailored to what the customer actually purchased.

5. Win-Back Flow

Every ecommerce list has a segment of customers who bought once or twice and then went quiet. They have not unsubscribed. They have not complained. They are just not engaging or buying anymore.

These customers are not lost. They are recoverable. And recovering them costs a fraction of what acquiring a new customer costs.

A win-back flow targets customers who have not purchased in 60 to 90 days (the right window depends on your average purchase frequency) with a sequence designed to re-engage them. Done well, a win-back flow typically recovers 5 to 12% of lapsed customers. Done with the right creative and the right offer, that number can be higher.

We built a gamified win-back campaign for one of our clients that is one of the best examples of this done right. It combined personalisation, a game mechanic, and a time-limited incentive. The open rates and click rates on that sequence significantly outperformed their standard campaign benchmarks, and it brought back customers who had not purchased in months.

A win-back flow is also a list health tool. Customers who go through the full sequence and still do not re-engage should be suppressed from your active list. Emailing disengaged subscribers damages your deliverability score and hurts the performance of every other email you send.

The Flows Most Brands Are Missing But Should Add

Once the five core flows above are in place and performing, the next layer of automation to add includes:

Back-in-stock alerts. If a customer viewed a product that was out of stock, notifying them the moment it is available again converts at exceptional rates because the intent is already established.

Price drop alerts. For customers who viewed a product at full price and did not buy, a notification when that product goes on sale closes the loop.

Replenishment reminders. If your brand sells consumable products, a timed reminder based on the average usage cycle of what a customer bought last is one of the most underused flows in DTC ecommerce. The timing is predictable. The relevance is guaranteed.

VIP flows. Your highest-value customers deserve a different experience than a new subscriber. A VIP flow recognises repeat buyers, rewards loyalty, and deepens the relationship with your most profitable customer segment.

What a Broken Flow Architecture Looks Like in Practice

When a new client comes to Retain Marketing, we almost always find the same issues across their Klaviyo account. Flows that send at fixed times rather than behaviour-triggered intervals. Welcome series that are three emails long and have not been updated since the account was set up. Abandoned cart flows with a single email. No browse abandonment. No post-purchase sequence beyond an order confirmation. A win-back flow that is either absent or paused.

Each of these gaps represents lost revenue that is already in your ecosystem. The customers are there. The intent is there. The system to convert them just is not.

A US sneaker brand we worked with had all five core flows in place when they came to us. But they were built incorrectly, firing at fixed times, using outdated creative, and operating with no SMS integration. After we rebuilt the architecture properly, they saw 396% growth across their automated flows. The list did not change. The products did not change. The system changed.

The Bottom Line

You do not need 20 flows to have a high-performing email programme. You need five built correctly, running on behaviour-based triggers, refreshed regularly, and integrated with your SMS where appropriate.

Those five flows, done properly, should be generating 15 to 20% of your total store revenue on autopilot every single month.

If yours are not, the architecture needs rebuilding.
