Sales promotion is the part of marketing that is supposed to work fast: not brand building, not positioning, but a time-limited incentive that pulls a purchase decision into this week instead of the next.
In e-commerce it is unusually visible, because it runs almost entirely through owned channels: email, app, homepage, customer account. So it is possible to describe which tactics are actually in use, not only which ones appear in textbooks. The examples here come from newsletters sent by German online retailers that Reyo recorded in the four weeks from 7 September to 4 October 2026. We do not name the shops, this is about the patterns, not the senders. And the limit of our data is clear: we see what was sent, not how it performed.
What counts as sales promotion
Sales promotion covers every time-limited measure that adds a reason to buy now. Three features define it:
- It ends. A permanent price is pricing, not an incentive.
- It has a condition: a minimum order value, a product selection, a code, a membership, or simply the stock on hand.
- It targets an impulse. The purchase is supposed to happen now, not eventually.
That separates it from its neighbours: advertising builds attention, public relations works on the company's image, pricing sets the permanent price level. Sales promotion sits on top, and that is where the risk sits: promote permanently and you have changed your price level without deciding to.
Marketing theory splits it three ways: consumer promotion (discounts, gifts, prize draws), trade promotion aimed at retailers (listing fees, co-op advertising, secondary placements) and sales force promotion (contests, training). A direct-to-consumer shop lives in the first category. Brands selling through marketplaces and retailers deal with all three.
What sales promotion is good for
A promotion without a stated goal gets judged on revenue during the promotion days, and any discount delivers that. Name the goal first. There are five:
- Sell-through: clear stock, close out a season, make room for the next range.
- Acquisition: trigger the first order.
- Basket value: more items per order, usually through thresholds.
- Reactivation: win back customers who have not bought in months.
- Channel shift: app install, sign-up or membership, so a relationship instead of an order.
What it cannot do: build a brand, rescue a weak product, or raise willingness to pay for good. It shifts demand forward and buys attention, and both have a price.
The toolbox at a glance
| Tactic | What it triggers | Typical side effect |
|---|---|---|
| Percentage discount | immediate impulse, broad reach | reference price drops, customers learn to wait |
| Fixed amount above a threshold | higher basket value | orders cluster just above the threshold |
| Free gift with purchase | attention without cutting the price | fulfilment effort, stock runs out |
| Shipping and service | fewer checkout abandonments | quickly becomes an expectation |
| Membership, app, account | channel and data instead of margin | friction before the first use |
The interesting question is which fields the market really plays.
The tactics German online retailers use
Across the four-week window, close to two thirds of all recorded emails were promotional, meaning they carried a concrete offer, and a little more than half carried a price reduction. The gap matters: roughly one in six promotional emails worked without any discount. That is the part most teams forget.
Percentage off: the default, and its shop window
The percentage discount is the most common incentive, used in about every third email. The typical fixed discount sat at 20 percent, the top quartile started at 30. Where retailers advertised an "up to" range, the midpoint was 50 percent.
- A beauty retailer gave 20 percent on one skincare line, against list price and only while stocks lasted.
- A furniture retailer advertised up to 68 percent below list price, plus 10 percent for app users, excluding leaflet and hot-deal items.
- A book retailer tiered the percentage by basket: 12 percent from 20 euros, 15 percent from 25 euros, limited to second-hand stock.
How to read it: the headline number and the actual reduction are two different things. Between a 20 percent median on fixed discounts and the 50 percent midpoint of "up to" ranges sits the gap your subject line has to bridge. Compare only shop-window numbers and the market looks more aggressive than it is.
Fixed amounts and thresholds: the basket lever
A cash amount was the incentive in roughly one in thirteen emails. It is predictable, and it attaches cleanly to a threshold.
- A fashion retailer ran a triple tier: 30 euros off from 150, 40 from 200, 50 from 250 euros order value.
- An online pharmacy offered 5 euros from 59, 10 euros from 79 and 15 euros from 139 euros, restricted to over-the-counter products.
- A nail care brand gave 25 euros each to the referring customer and the friend, conditional on a first order.
How to read it: just under one in ten emails named a minimum order value, and the typical one was around 72 euros. A tier beats a flat percentage for basket growth, because it ties the giveaway to the value you want. The cost: many orders land just above the threshold, where margin is thinnest.
Gifts and multi-buy: incentive without a percent sign
Free items were the stated incentive in roughly one in twenty-five emails, gifts in some form in about one in ten, multi-buy mechanics such as three for two in about one in twenty.
- A lingerie retailer made the cheapest of three items free, redeemable once.
- A fashion retailer added an umbrella to every order on a single Sunday, while stocks lasted.
- A tool retailer added a free accessory on invoices above 450 euros.
How to read it: the gift is the underrated instrument. It costs the purchase price of the item you add, not a percentage of the basket, and leaves the reference price of your core range untouched. For consumables, multi-buy also raises units per order, though it pushes the next purchase out. For durables it does not work.
Shipping and service: rarely the promotion, usually the baseline
This was the clearest finding in the window. Free shipping was mentioned in roughly one in twenty emails, but in only about one in seventy was it the reason for the email. Mostly it sat in the footer as a permanent promise above a threshold.
- A lingerie retailer made a free shipping day the promotion itself, valid today only.
- A fashion retailer gave free shipping until midnight via a code, conditional on a 30 euro minimum.
- A shoe retailer promoted store pickup as the shipping-free option.
How to read it: shipping cost is a common reason for checkout abandonment, but as a permanent footer promise it has no pull left, because it is expected. Make it time-limited and visible and you have a lever that costs no percentage points on your range. In the fourth quarter that counts double.
Membership, app and account: the promotion as a channel shift
About one in fourteen emails tied the benefit to the app, about one in twenty to a membership, club or account.
- A grocery retailer gave 10 percent bonus on its organic own label, conditional on an account and an activated coupon.
- A fashion retailer offered 10 euros off the next order above 100 euros, triggered by an app download.
- A lingerie retailer reserved a multi-buy promotion for the checkout of signed-in members.
How to read it: this is sales promotion that comes out of the channel budget rather than the margin. The discount pays for an install or a sign-up, and those outlast the promotion. The catch: every condition costs conversion, and unlocking the benefit only after a download loses everyone who wanted it now. Our guide to customer retention in e-commerce covers that trade.
Prize draws: attention instead of a discount
In roughly one in twenty-five emails the offer was a chance to win rather than a price advantage. A furniture retailer drew five fan packages and asked for nothing but entry, a book retailer put up prizes worth 15,000 euros conditional on the loyalty card, a lingerie retailer tied a draw to membership and a two-day deadline.
How to read it: a prize draw costs a fixed sum instead of a percentage of revenue and delivers data and reach. It does not trigger a purchase, and entrants without buying intent dilute your lists. Fine as the opening of a season, expensive as a permanent tactic.
The condition is half the tactic
The mechanic is in the subject line, the economics are in the fine print. About one in seven emails named exclusions, roughly one in eight ruled out combining with other discounts, and about one in eight limited the offer to available stock.
Duration is the sharpest signal: a good half of all recorded promotions ran a single day, and more than one in three emails used an urgency cue. Sales promotion in e-commerce is day-to-day business: one mechanic, one day, one impulse.
Three conditions decide the outcome:
- The minimum order value steers the basket. Set it above your current average, or you subsidise orders that were coming anyway.
- The exclusion protects the margin. New arrivals, thin-margin own labels and already reduced items belong outside the offer, before launch rather than after the first complaint.
- The deadline creates the impulse, and only works if it holds. An extension without a reason buys revenue this weekend and costs credibility next year.
In the EU a legal layer sits on top: advertising a price reduction means stating the lowest price of the previous 30 days. What you mark down in October decides what still counts as a reduction in December.
Planning a promotion in five steps
- Set one goal, not three: sell-through, acquisition, basket, reactivation or channel.
- Match the tactic to the goal: a threshold for basket value, a fixed amount for acquisition, a percentage for sell-through, an app benefit for channel.
- Write the condition and the deadline first: minimum order value, exclusions, end date, and what happens if stock runs out.
- Check the reference price: what the item cost in the 30 days before, and what you want to do with that price afterwards.
- Put the market next to it. If three competitors send the same mechanic in the same week, your 20 percent is background noise.

Three mistakes to avoid
Run a promotion every week and the promotional price simply becomes your price. Add the goal after launch and the promotion has always worked. Extend the deadline three times and nobody believes the fourth.
How Reyo helps
Sales promotion is a decision about timing and mechanics, and both depend on the market:
- Competitor monitoring records competitor promotions with mechanic, condition, minimum order value and duration, not just a screenshot.
- The campaign planner puts your promotions next to market dates, so two of your own do not undercut each other.
- Market predictions show which weeks your category is typically under promotional pressure.
For the current quarter, the dates and windows are bundled in the Q4 guide 2026.
Conclusion
Sales promotion is more than percentages. Roughly one in six promotional emails in German retail works without any price reduction: a gift, shipping, a membership, or simply a deadline. Those tactics cost less margin and protect the reference price you still need next quarter.
The order matters: goal first, then tactic, then condition. Start at the 20 percent and you buy revenue you would have had anyway.
