Email marketing for ecommerce

Why email marketing pays more than any other ecommerce channel

_□×

Everyone on your list has already bought from you or asked to hear from you. There is no bid to win, no algorithm to satisfy, and no platform that can take the audience away overnight. That makes email the cheapest sale in the business and the only channel where the audience is genuinely yours.

The second reason is time. A paid ad stops working the moment you stop paying, and a campaign earns on the day you press send. A flow built this month is still selling in two years, at three in the morning, while you are packing orders. Industry figures put email's return at roughly £36 for every £1 spent, and automated messages earn several times more per recipient than a scheduled campaign. Those numbers are averages and your shop will not be average, but the direction never changes: the money is in the automation you have not built yet.

The third reason is margin. Email revenue carries no acquisition cost. When a customer buys a second time through a post-purchase flow, that order is close to pure contribution. Shops that fix retention do not just earn more, they can afford to bid harder on the front end, which is where most of the compounding comes from.

What good ecommerce email marketing looks like in practice

_□×

An account in decent shape has three moving parts. Flows, which are the automated messages triggered by behaviour. Campaigns, which are the sends you plan. And the list itself: how it grows, how it is segmented, and how carefully it is looked after.

Most shops have some version of all three, but unevenly. Flows are half built. Campaigns go out in bursts, then nothing for six weeks. The list has grown, but nobody has removed the addresses that have not opened anything since 2023, so deliverability is quietly sinking and nobody has noticed because the reporting only shows the people who did open.

Fixing that is not a creative problem, it is a sequencing problem. My services page lays out how the work splits between building, sending and maintaining, but the short version is that you build the automation once, then spend your monthly time on campaigns and hygiene.

The five ecommerce email flows, in build order

_□×

These five cover most of what automation can earn. Build them in this order, because the earlier ones pay for the later ones.

1. Abandoned cart

Three emails, the first inside the hour. This is the fastest money in any account because the intent is minutes old. Send a reminder, then an answer to the objection, then a reason to decide.

2. Welcome series

Five emails, branched by what the subscriber browsed. This is where you set, or deliberately avoid, the discount habit, and where you explain who makes the thing and why it costs what it costs.

3. Browse abandonment

Catches interest before a cart ever exists. Lower intent than cart, higher volume, and it needs a light touch so it does not feel like surveillance.

4. Post-purchase

Turns a first order into a second: delivery reassurance, care instructions, a review request timed to when the product has actually been used, then a reorder nudge on the real consumption cycle.

5. Winback

Re-opens lapsed buyers, segmented by what they bought and when. A candle buyer and a £400 coat buyer do not lapse on the same timeline and should not get the same email.

How I would fix an ecommerce email account, step by step

_□×

Check that what exists actually sends

Switched on is not the same as sending. I open every flow and read the send count on each individual email. A wrong trigger, a filter left in from a test, or a step that has delivered eleven emails in a year is the single most common finding.

Fix deliverability before adding volume

Authenticate the sending domain, remove dead and mistyped addresses, and suppress people who have not engaged in a year. Sending more mail to a bad list makes every other number worse.

Build cart, then welcome

Those two carry most of the recoverable revenue. Everything after them is improvement rather than rescue.

Then send campaigns into a working account

Four to eight a month, in your voice, in a template built for a phone first. Two genuinely useful emails for every one that sells something. Whichever tool you are on, the shape of the work is the same, there are twelve platforms I build in and the strategy does not change between them.

What results are reasonable to expect from ecommerce email

_□×

Cart and welcome flows usually show something within the first fortnight, because the traffic that triggers them already exists. You are capturing demand you were previously losing, not creating new demand.

Campaign revenue moves more slowly, roughly two months, as the sending rhythm settles and the list gets used to hearing from you regularly. Deliverability repair is slower still, because inbox providers judge you on a rolling history rather than on this week's behaviour.

What I will not do is quote you a percentage before looking at your list size, traffic, average order value and margins. Anyone who does is guessing, and the guess is always flattering. The free audit gives you the honest version instead, and the findings are yours whether or not you hire me.

Ecommerce email marketing FAQs

_□×

How often should an ecommerce store send emails?

Four to eight campaigns a month suits most shops, on top of flows running continuously. Consistency matters more than frequency: a predictable weekly send outperforms a burst of six emails followed by two months of silence.

How big does my list need to be for email marketing to be worth it?

Flows are worth building at almost any size, because they cost you once and run forever. Campaign revenue becomes meaningful around a few thousand engaged subscribers. Below that, the priority is capture and the welcome series.

Should I offer a discount to get signups?

Sometimes. A discount grows the list faster but trains people to wait for one. If your margins are thin or your product is genuinely differentiated, lead with early access, restock alerts or the story instead.

Do I need a big email platform to do this properly?

No. Most shops are already on a tool that can do everything described here. Switching platforms is a last resort, see pricing for how the monthly work is structured, migration or not.

How long until I see results?

Two weeks for flow revenue, around two months for the campaign rhythm to show up in your reporting, longer if deliverability needs repairing first.
