SMS is the most direct line a fashion brand has to its customers. Text messages are opened within minutes and read at rates email can only dream of — which is exactly why SMS is so easy to ruin. People let a brand into their text inbox as a privilege, and a single spammy blast can lose a subscriber for good. Used with restraint, SMS becomes a powerful retention and revenue channel; used carelessly, it is an unsubscribe machine. The difference comes down to consent, relevance and timing. This starter guide covers how to build an SMS programme that customers actually welcome and that genuinely drives sales.
Why SMS works — and why that is dangerous
The power of SMS is its intimacy. A text sits next to messages from friends and family, gets seen almost immediately, and carries a sense of personal directness no other channel matches. That same intimacy is the risk: people guard their text inbox far more jealously than their email, so the bar for what deserves a message is much higher. Treat every send as something a real person chose to receive, and you stay welcome; treat it as a cheap broadcast, and you are gone.
Build the list the right way
SMS marketing lives and dies on consent, and getting list-building right protects both your results and your legal standing. You must have clear permission to text people, so build your list deliberately and compliantly rather than scraping numbers.
- Collect numbers through explicit opt-ins — checkout, signup forms, and pop-ups with a clear offer.
- Make the value obvious: early access, exclusive drops or a welcome discount in exchange for the number.
- Set expectations on what they will receive and how often, then honour it.
- Always include easy opt-out and follow the messaging consent rules that apply in your region.
Run the flows that earn their keep
As with email, automated SMS flows do the highest-return work because they reach people at the right behavioural moment. A few well-built flows quietly recover and grow revenue without you sending a thing manually. Keep them short — SMS is not the place for long sequences.
- Welcome text: deliver the promised offer immediately and set the tone the moment someone subscribes.
- Abandoned cart: a timely, friendly nudge with the items left behind is SMS at its most effective.
- Order and shipping updates: genuinely useful texts that build trust and reduce support questions.
- Back-in-stock and price-drop alerts: high-intent, welcome messages people are glad to receive.
Send campaigns sparingly and well
Beyond automated flows, you will send broadcast campaigns for launches, sales and drops. The temptation is to send often; the discipline is to send rarely and make each one count. Because attention is so high, a single great SMS campaign can outperform a month of mediocre emails — but over-send and your unsubscribe rate spikes.
- Reserve campaigns for genuinely worthwhile moments — a real launch, a real sale, a real restock.
- Segment so people get messages relevant to them rather than blasting the whole list every time.
- Mind timing and time zones; a text at the wrong hour is far more intrusive than an email.
- Track unsubscribe rate as closely as revenue — it is your early warning that you are over-sending.
Write SMS that respects the medium
SMS copy is its own craft. You have very little space and a reader who decides in a glance whether to care, so every word works hard. The best texts feel personal, get to the point fast, and make the next step obvious.
- Lead with the value or the offer immediately — no slow build-up.
- Keep it short, conversational and human; this is a text, not a press release.
- Include one clear call to action and a clean link, not a wall of options.
- Add a touch of personality and, where you can, personalisation that makes it feel one-to-one.
Combine SMS with email, do not replace it
SMS is not a replacement for email — it is a complement. Email handles depth, storytelling and frequent contact; SMS handles urgency and the moments that truly matter. The strongest programmes coordinate the two so a customer gets the right message on the right channel without being bombarded on both. Reserve SMS for the high-priority moments and let email carry the everyday relationship.
