You send an offer to your entire customer base. The open rate looks fine, a few people click, and you end up with three orders. For a list of 2,000 contacts, that is frustrating. The problem rarely comes from the product or the price: it comes from the structure of the email and the rhythm of the sequence.
In 2026, email marketing remains one of the most profitable channels for a small or medium business in French-speaking Switzerland. No ad auction, no algorithm deciding your reach: your list belongs to you. One send costs a few francs, and a well-run campaign can generate several thousand francs in revenue. You simply have to structure it properly.
Here is the anatomy of a promotional email that sells, the three-send sequence that clearly improves results, and the mistakes that cost the most money.
The calculation few SMEs run
Take a fictitious example. A furniture shop in Lausanne has a list of 3,000 subscribers. It launches an end-of-financial-year clearance.
- Open rate: 38%, meaning 1,140 readers
- Click rate: 4% of the list, meaning 120 visitors on the page
- Conversion rate on the page: 5%, meaning 6 orders
- Average basket: CHF 480, so CHF 2,880 from a single send
Actual cost: around CHF 20 in platform fees and two hours of work. Now imagine the sequence moves to three sends and the click rate rises to 6% thanks to a better subject line and a better structure. You go past CHF 7,000 on the very same list, without a single extra franc of advertising. That is where email profitability is decided: in the structure, not in the size of the database.
The anatomy of a promotional email that converts
An email that sells is not a catalogue. It is a short sales page, made of seven blocks in a precise order.
1. The subject line: a promise, not an announcement
The subject line weighs very heavily on the outcome, because without an open there is no sale. Avoid "Our monthly newsletter". Prefer a concrete, dated benefit: "30% off sofas until Friday" or "Your painting quote at CHF 890, valid 5 days". Stay under 50 characters so it displays in full on mobile, where a large share of emails are read.
2. The preheader: your second chance
This is the grey line shown after the subject in the inbox. Never leave it empty, or it will display "View this email in your browser". Use it to complete the subject line rather than repeat it: add the condition, the deadline or the figure that is missing.
3. The hook: one sentence, one problem
The first three lines must name the reader's situation. "Your living room is short on space and you have been postponing the purchase for six months." The reader has to recognise themselves before you talk about the product.
4. The offer: quantified, limited, single
One offer per email. As soon as a send contains three different promotions, the reader does not choose: they close it. State the price, the real saving in francs and the end date. "CHF 1,290 instead of CHF 1,690, until 30 September" is far more effective than "enjoy our exceptional offers".
5. The proof: what removes doubt
Two lines are enough: a genuine customer review, a sales figure, a guarantee, or a delivery and returns note. In Switzerland, "shipped from Geneva within 48 hours" or "2-year warranty, free exchange" does more for conversion than three paragraphs of product description.
6. The button: one verb, one action
One button visible without scrolling, repeated once at the bottom of the email. The label describes the action, not the mechanism: "See the discounted models" converts better than "Click here". The link must point to the exact offer page, never to the homepage.
7. The postscript: the reminder that catches up
Many readers skim and jump straight to the bottom. The P.S. restates the offer in one line, with the deadline. It often recovers clicks that the top of the email missed.
The whole thing should fit in 150 to 250 words. A promotional email is read in a few seconds: it is not a blog article. If you lack the time to produce these texts every month, this is exactly the kind of work covered by our content creation service in Geneva.

The three-send sequence
A single email captures the buyers who had already made up their mind. The others need a reminder. A sequence of three sends spread over ten days often generates considerably more orders than a single send, without adding a single contact to the list.
Send 1: the announcement (day 1)
The full structure described above, addressed to the whole eligible base. Ideally on a Tuesday or Wednesday in the late morning for a professional audience, or in the early evening for consumers.
Send 2: the argument (day 4)
Sent only to people who did not buy. Change the angle completely: do not repeat the announcement, tell a customer story, show a before-and-after comparison, or answer the three most common objections. Different subject line, different content, same offer.
Send 3: the deadline (day 9 or 10)
Sent to non-buyers, short, almost blunt: three sentences, the date, the button. This is very often the send that produces the most orders in the whole sequence. One condition only: the deadline must be real. A cut-off date that never actually arrives destroys your credibility within two campaigns.
These three sends can be programmed once and for all in an automated scenario. Setting up a marketing automation workflow turns repetitive work, redone for every campaign, into a few minutes of preparation.
Segmentation: the most profitable lever
Sending the same offer to the entire database is the most expensive mistake. Four segments are enough for most SMEs.
- Active customers (a purchase in the last 12 months): these are the people who buy. Direct offer, no need for long explanations.
- Dormant customers (12 to 36 months): add a reason to come back, a returning-customer advantage or a new product.
- Prospects who never bought: the promotion alone is not enough, reinforce proof and reassurance.
- Email-inactive contacts (no open in 6 months): isolate them completely, they damage your deliverability and push your sends into spam folders.
Even rough segmentation usually lifts the click rate considerably. Add a language criterion if your database also covers German-speaking Switzerland: an email in French sent to a German-speaking contact is a wasted email, and often an unsubscribe.
The mistakes that kill sales
- Several offers in the same email. One offer, one button, one decision.
- A vague subject line. "Our latest products" has never made anyone open an email. Always include a figure or a deadline.
- An email that is too long. The longer the text, the more the click rate tends to drop. The detail belongs on the destination page, not in the inbox.
- An inconsistent landing page. If the email announces 30% off and the page mentions it nowhere, the sale is lost. The offer must appear at the top of the page.
- No follow-up. Stopping after the first send means leaving a good share of your potential orders on the table.
- Sloppy mobile rendering. Test every send on a phone before launching. A button that is too small or an image that fails to load costs sales directly.
- Ignoring the legal framework. In Switzerland, unfair competition law requires prior consent, clear identification of the sender and a working unsubscribe link. A non-compliant send exposes you to a complaint and to your domain being blocked.
The three figures to track
Three indicators are enough to steer a campaign (the thresholds below are rough benchmarks). The open rate judges your subject line and your sender reputation: aim above 30% on a clean database. The click rate on the whole list judges your offer and your structure: aim for 3 to 6%. The revenue per email sent judges everything: divide the revenue generated by the number of emails delivered. Between CHF 0.50 and CHF 2 per email sent, your campaign is healthy.
Write these three figures down after every campaign in a simple table. After six sends, you will know exactly which kind of subject line, which day and which kind of offer works in your market: information no general study will ever give you.
Where to start
Do not rebuild everything at once. On your next promotion, apply five rules: one single offer, a subject line with a figure, seven blocks, three sends, two segments. Then compare with the results of your last campaign. The difference often shows from the very first attempt.
