Ecommerce email and CRM platforms: what they do and how to judge them
The point of these tools is retention: getting customers to buy again. Where the money is made or lost sits in the contribution margin of those repeat orders, not in the email dashboard.
What does it do?
It keeps a customer list, sorts customers into groups, and sends messages when something happens.
Flows. Email automation flows are sequences of emails sent automatically when a customer does something or meets a condition: welcome, abandoned cart, post-purchase, win-back and replenishment. One email vendor's getting-started guide defines a flow as automated actions triggered by a behaviour or event, and suggests setting live, in order: welcome series, abandoned cart, post-purchase and winback1.
Abandoned cart. The flow that matters for cart abandonment rate: messages to people who left items in the basket. One email vendor's help page says its classic abandoned cart email needs a connected supported store or an API integration, and is a single email sent 1, 6 or 24 hours after the cart is left; a series is a separate option2. Other tools differ, so do not assume one default fits all.
Segments. Customer segmentation splits your base into groups that share behaviours, so each group gets different messages.
Records. The platform holds what each customer bought and when. That is the raw material for repeat purchase rate and LTV. It is not a replacement for the shop's order records.
Why do e-commerce brands use it?
Our view: a returning customer is usually cheaper to reach than a new one. For most shops, email is the first retention tool to set up, because the list already exists.
It also runs while nobody is looking. A flow sends the same message at the same moment, every time. That is both its strength and its risk.
How do we implement it?
Check the order data
Confirm the shop's order data is reliable before you buy a platform. Cart and order flows depend on it.
Connect the shop
Check which events pass through and that customer records match. Integration with your shop platform matters more than any feature list.
Plan each flow
Decide who gets it, when, and what the message says. Then someone reviews it, so it does not mention a product you stopped selling.
Check credited revenue
Compare the revenue the platform credits to emails with shop data and a comparison group before it reaches a board report.
When should you not use it?
Do not buy a platform before the shop's order data is reliable.
Do not add flows to cover a product or price problem.
Do not report email revenue to the board without a check against shop data.
What does it cost in effort?
No figures. The effort is:
- Integration. Connect the shop, check which events pass through, and check the customer records match.
- Flows. Plan each one: who gets it, when, and what the message says. Then maintain them.
- Segments. Define groups and keep them current.
- Content. Someone writes and designs the emails.
- Deliverability. Getting into the inbox, not just being delivered to the server. Watch it separately from open rates.
- Consent. What you may send to whom is a legal question. Your counsel decides.
- Reading. Reports credit emails with sales. Someone has to question that.
Pitfalls
Taking credit for orders that would have happened
A customer who clicked an abandoned cart email may have been about to buy anyway. Our view: that is what the comparison group is for.
Judging by open rate
Our view: opens are a weak signal on their own. Look at clicks and orders as well.
Too many discounts in the flows
Our view: a discount in every flow trains customers to wait for one.
A flow nobody reviews
It was fine at launch. Two years later it mentions a product you stopped selling.
Counting engagement as retention
Retention is repeat purchases, not engagement.
Copying vendor benchmarks
Return figures published by email vendors are marketing. Measure your own.
Our take: Selective
In our view, email and CRM platforms are Selective. That is our rating, not a market fact.
Our reasoning: the category is useful, but the right platform depends on your shop and its scale. Cart and order flows depend on shop data; one vendor's abandoned cart email does not work without a connected store2. Our view: integration with your shop platform matters more than any feature list. We do not rank vendors on this page.
Our view: The revenue an email platform shows is the revenue it credits to emails. Check it with a holdout test or a comparison group before it reaches a board report.
FAQ
What is an ecommerce email platform?
A tool that stores customers and sends messages automatically, often based on events from your shop, such as a sign-up, a started checkout or a fulfilled order1.
What is email marketing automation for ecommerce?
Messages that send themselves when a customer does something: subscribes, leaves a cart, buys, or goes quiet. One vendor's guide suggests starting with welcome, abandoned cart, post-purchase and winback flows1.
Do I need a connected shop?
How many emails should an abandoned cart flow have?
It depends on your shop. One vendor's classic set-up is a single email, with a series as a separate option2. That is one tool's default, not a rule.
Can I trust the revenue the platform reports?
Treat it as credited revenue. Check it against shop orders and a comparison group.
Which platform is best?
It depends on your shop platform, list size and team. We do not rank vendors. For help with setup, see our ecommerce retention agency service.
