Quick answer: Ecommerce email marketing works best as a set of automated flows tied to what shoppers actually do: a welcome series for new subscribers, an abandoned cart or checkout reminder, post-purchase emails, a browse follow-up, and a win-back sequence for lapsed buyers. Build them in that order, then add campaigns on top.

Most online stores start email the same way: a newsletter whenever there is a sale. That is the weakest part of ecommerce email marketing. The emails that do the steady work are the ones triggered by a shopper’s behaviour, sent once, and left running in the background. This post walks through the five flows we would set up first for a store, what each one should say, and the mistakes that make them feel spammy. If you want the wider picture of what email marketing covers first, read our email marketing services guide.

What is ecommerce email marketing?

Ecommerce email marketing is email that an online store sends to move people from browsing to buying, and from one order to the next. It mixes two types of sending: automated flows that react to behaviour, and scheduled campaigns such as launches, seasonal offers and newsletters.

The difference matters. A campaign goes to a whole list or segment on a date you pick. A flow goes to one person at the moment they did something, like leaving a checkout half-filled. If the terms are new to you, our post on email marketing vs email automation breaks them down.

Which ecommerce email flows should you build first?

Start with the flows that sit closest to a purchase decision. The order below is the order we would build them in for a store with a working checkout and a small list.

Flow	Triggered by	Main job	Typical length
Welcome series	New subscriber	Introduce the store and earn the first order	3 to 5 emails
Abandoned checkout or cart	Checkout started, not paid	Remove the reason they stopped	2 to 3 emails
Post-purchase	Order placed or delivered	Reassure, help them use the product, ask for a review	2 to 4 emails
Browse follow-up	Product viewed by a known subscriber	Bring them back to what they looked at	1 to 2 emails
Win-back	No order for a set period	Re-start the relationship or clean the list	2 to 3 emails

The email counts are starting points, not rules. Fewer, sharper emails usually beat a long sequence nobody finishes.

How does an abandoned cart email flow work?

An abandoned cart flow sends a reminder when a known shopper starts checkout but does not pay. The store can only email people whose address it already has, so the flow depends on capturing the email early in checkout.

Platforms define “abandoned” differently, so check yours. Shopify’s help page on recovering abandoned checkouts, for example, explains that a checkout counts as abandoned once it stays incomplete for more than ten minutes after the customer has entered their email (last checked 31 Oct 2026). WooCommerce and custom stores usually need a plugin or your own logic to track this.

A simple three-step version looks like this:

1. Email 1, within a few hours: a plain reminder with the product image, name, price and one button back to the checkout. No discount yet.
2. Email 2, about a day later: answer the likely objection. Shipping cost, delivery time, returns, sizing or payment options. This is where most of the persuasion happens.
3. Email 3, a couple of days later: a final nudge. Add an incentive here only if your margins allow it and you are happy for regular shoppers to learn the pattern.

That last point is worth thinking about before you switch the flow on. If every abandoned cart gets a code, some customers will start abandoning on purpose. Many stores do better by leading with service details, like cash on delivery, delivery times or an easy exchange policy, and keeping discounts for specific products or first orders.

What should a post-purchase email sequence include?

Post-purchase emails should make the buyer feel sure about the order, then help them get value from it. Selling comes last.

• Order and shipping updates that are clear and on-brand. These are the most-opened emails a store sends, so the design should match the rest of your email.
• A how-to or care email once the product arrives: sizing, setup, ingredients, care instructions or a short video.
• A review request after the customer has had time to use the product, not the day it ships.
• A related-product suggestion that genuinely fits what they bought, sent later.

For a store, this sequence also cuts support messages. People ask fewer “where is my order” and “how do I use this” questions when the answers arrive before they think to ask.

How do browse follow-up emails differ from cart reminders?

A browse follow-up goes to a subscriber who looked at a product but never added it to the cart. The intent is weaker, so the email should be lighter: show the product, perhaps a few similar ones, and stop there.

Send one, or two at most, and exclude anyone who has already entered a cart or checkout flow so people never get two reminders for the same visit. Browse tracking only works for shoppers your platform can identify, usually because they clicked an earlier email or are logged in, and it should match what your privacy policy and consent banner say.

When should you send a win-back email?

Send a win-back email when a customer has gone quiet for longer than your normal buying cycle. A coffee or skincare store might see repeat orders within weeks. A furniture store might not see one for a year. Use your own order history to set the gap rather than a number copied from a template.

A win-back sequence usually has three jobs:

1. Remind: what is new since their last order, or a best-seller they have not tried.
2. Offer: a reason to come back now, which can be an incentive, early access or free delivery.
3. Ask: do they still want to hear from you? If they don’t open or click, stop sending or move them to a low-frequency segment.

That third email protects your sender reputation. Mailbox providers notice when you keep mailing people who never engage, which is why our email deliverability checklist treats list hygiene as seriously as authentication.

How do you keep ecommerce emails out of the spam folder?

Authenticate your sending domain, only email people who agreed to hear from you, and make unsubscribing easy. Google’s email sender guidelines set out its requirements for senders, including authentication and one-click unsubscribe for bulk senders (last checked 31 Oct 2026).

A few store-specific habits help too:

• Keep order confirmations and shipping updates separate from promotional sends where your platform allows it, so a marketing complaint doesn’t slow down receipts.
• Don’t add every checkout email to your marketing list by default. Use a clear opt-in box.
• Watch out for flows overlapping. Without exclusions, one shopper can get a welcome email, a cart reminder and a sale campaign on the same day.

If your domain email is still being set up, ResellerBytes has a useful guide on protecting your domain from email spoofing that covers the records involved.

How do you measure whether your flows are working?

Measure each flow by the orders it helps create, not by opens alone. Open rates have become unreliable because of privacy features in some email apps, so clicks, placed orders and unsubscribes tell you more.

For each flow, track:

• Orders and revenue attributed to the flow, using your platform’s attribution window and UTM tags in every link.
• Click rate on each individual email, to spot the one where people drop off.
• Unsubscribe and spam complaint rates, especially in the win-back flow.
• For cart flows, how many recovered orders used a discount, so you know what the reminders really cost.

Then change one thing at a time. Test the subject line or timing of the first cart email before you rewrite the whole sequence. Our older post on A/B testing email campaigns covers how to run that kind of test.

What does the store itself need before flows can work?

Flows rely on clean data from the store. Before writing a single email, check that product images and prices pull through correctly, that the checkout captures email early, that customer consent is recorded, and that your platform passes order events to your email tool.

This is the step that gets skipped most often. When we take on email marketing, the work starts with a list and platform assessment: the email platform, subscriber list health, sending history and past campaign results. Only after that do we plan, design responsive templates and write the copy for each segment, then test rendering, links and spam scores across Gmail, Outlook and Apple Mail before anything goes live. That order is the same whether a store has a few hundred subscribers or a large list.

If the store itself still needs work, ResellerBytes’ guide on building a successful ecommerce website is a good place to start, and our Shopify conversion tips cover the on-site side of the same problem.

Frequently asked questions

How many emails should an abandoned cart flow have?

Two or three is a sensible start: a quick reminder, an email that answers the likely objection, and an optional final nudge. Test before adding more, because extra reminders can raise unsubscribes faster than they recover orders.

Should abandoned cart emails include a discount?

Not by default. Lead with the product and with service details like delivery and returns. If you add a discount, put it in the last email and limit how often one customer can receive it.

What is the difference between abandoned cart and abandoned checkout emails?

A cart email follows someone who added items but didn’t start checkout. A checkout email follows someone who began checkout, usually after entering their email. Many platforms only support checkout recovery out of the box, because that is where the email address is captured.

How long should I wait before sending a win-back email?

Base it on how often your customers normally reorder. Look at the typical gap between first and second orders in your own data, and start the win-back flow once a customer has gone well past it.

Do I need a separate email tool for ecommerce flows?

Not always. Some store platforms include basic abandoned checkout and customer emails. A dedicated email tool makes sense when you need segmentation, several flows with exclusions between them, and detailed reporting by flow.

Are welcome emails part of ecommerce email marketing?

Yes, and they are usually the first flow to build. Our welcome email sequence template gives a five-email structure you can adapt for a store.
