Best marketing strategy for e commerce compared, and the order that decides which channel you buy first

There are three coherent strategies for an online store and almost every store picks the wrong one, because the choice is usually made by channel fashion rather than by the single number that actually decides it. That number is how often a customer buys again.

The three strategies

Retention first. Spend almost everything on the people who have already bought. Email, messaging, replenishment reminders, a reason to come back. Correct when customers buy repeatedly, which is consumables, apparel basics, pet, beauty and food.

Acquisition first. Spend almost everything on reaching new buyers, because each one buys once and generously. Correct for furniture, mattresses, high value one off purchases and most considered goods.

Marketplace first. Let Amazon or another marketplace supply the demand and compete on listing quality and price. Correct when your category is searched on the marketplace rather than on the open web, and when your margin survives the fees.

The number that chooses between them

Purchases per customer per year, from your own order data. Not a benchmark, not an industry figure, yours. Pull twelve months of orders, count distinct customers, divide.

Under about 1.2, you are an acquisition business whether you like it or not, and a retention programme will be a small polite newsletter that moves nothing. Above about 1.8, you are a retention business, and the acquisition spend you are proud of is quietly subsidising a leak at the back. Between the two you are in the band where the cheapest wins come from the retention side, because the audience is already yours and the cost of reaching them is close to zero.

That one calculation is the strategy. Everything after it is execution.

What the retention tooling actually costs, since that is the cheap half

If the number puts you in retention first, the published arithmetic is worth seeing before you pick a tool. Read at omnisend.com/pricing on 21 October 2026, the free plan allows "Send up to 500 emails per month" and "Reach up to 250 contacts each month", Standard is 11.20 dollars a month billed monthly with 6,000 emails a month, and Pro is 41.30 dollars a month billed monthly with unlimited emails. SMS is an add on rather than included, described as "Charged separately, per SMS" with the Pro card showing "SMS starting at $0.007", and the FAQ says Pro includes "bonus SMS credits equal to your monthly bill".

Read at klaviyo.com/pricing the same day, the free plan allows "Up to 250 active profiles" and "500 email sends/month" plus "$5 of mobile messages/month", and no paid price for email or SMS renders on the page at all. That is a real difference between the two for a buyer trying to budget. Two cautions about that reading, both stated rather than resolved: the page served was the UK English pricing page while its calculator showed a figure in US dollars, and the page contradicts itself on support, with the free plan highlights showing email support while the FAQ limits it to the first 60 days.

This page does not rank the tools, because that is a different purchase and the comparison lives elsewhere on this site. The figures are here because the cost of the retention half is small and knowable, and that is itself an argument for doing it first whenever your repeat rate allows.

The order that works, whichever strategy you chose

Fix the product page before buying any traffic. Photography, the delivery promise, the returns policy and the review count. Traffic to a page that does not convert is a tuition fee.

Capture the email and the phone number at the only moment anyone gives them. Checkout and immediately after. It is free and it is the asset the rest depends on.

Then one acquisition channel, properly. One, run well, beats four run thinly, and you will learn which one from your own data rather than from an article.

Then the second channel, chosen by what the first one taught you.

The surface none of the three strategies has a line for

All three strategies assume the shopper arrives at a page you control or a listing you manage. A growing share of product decisions now happens before that, with a shopper asking an assistant which brand to buy in a category and getting two or three names back in prose. There is no impression, no click and no order to attribute. If you are not among the named brands, no channel report shows a gap.

AI Knows Us exists for that single row, and we are not a marketing platform and we run no channel. We send no email, place no advertising and manage no listing. We watch the buying questions your market asks across ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews and report which answers name your store, which name a competitor and which name nobody at all. The limits to judge us on are published rather than quoted on a call. At aiknowsus.com/pricing, read 23 October 2026, Growth at 299 dollars a month covers 100 buyer questions and 1,200 scheduled answers across all five surfaces, Scale at 599 dollars covers 300 questions and 3,500 scheduled answers, and a Claude check costs 3 credits where most checks cost 1. SEO Start at 149 dollars renders zero buyer questions, zero credits and zero engines, so it does not do this job and the floor price is not the price of this work. The page also publishes a free scan, in its own words "Run a free scan on your own domain and read what the AI apps say about you today", with "No account needed".

Where a rival beats us, and it is the fact a procurement reviewer will care about most. Our rendered pricing text carries no SSO, no SOC 2, no ISO certification, no white label and no data processing agreement, checked on 21 October 2026. Vendors in our own category do publish some of those. If you are buying under a security review, that absence is the more important fact about us than anything else on this page. And an honest sequencing note for a small store: if your repeat rate is above 1.8 and you have no email programme, build the email programme first. On Omnisend's own published figures that is 11.20 dollars a month, and it will return more than any measurement will.

Scope

This page is about choosing a strategy. It deliberately does not target ecommerce marketing platform, ecommerce marketing platforms, ecommerce marketing software, ecommerce digital agency or ecommerce marketing agency, all of which existing pages on this site already pool, and those are the pages to read once the strategy question is settled and you are choosing a tool or a supplier.

What store owners ask

Should I be on every channel. No. One acquisition channel run properly outperforms four run thinly, every time, at every size.

Is email still the best return. For any store with a repeat purchase pattern, yes, and the published entry prices above show why. It is the cheapest thing on the list.

When should I add a marketplace. When your category is searched there and your margin survives the fees, and knowing that requires checking rather than guessing.

If the question underneath this one is whether your store needs an app at all, our page on ecommerce app development and the four kinds of build. No other page on this site links to that one, measured on 21 October 2026 across 2,490 stored bodies (2,118 published drafts plus 372 fetched live pages) against 2,404 live pages, with my own wave excluded. 978 of those 2,404 pages, 40.7 percent, carry no inbound link from anywhere on the site, and that figure is an upper bound, because a body we cannot read cannot be counted as a linker.
