Text Marketing: The Channel Most Brands Treat as an Afterthought

Text marketing is one of the highest-performing direct channels available to marketers right now, and most brands are either ignoring it or using it badly. At its core, it means sending promotional or transactional messages directly to customers via SMS or MMS, with their explicit consent. Done well, it drives real revenue. Done poorly, it burns through your list and your reputation simultaneously.

The reason it underperforms for most brands has nothing to do with the channel itself. It has everything to do with how it gets positioned inside the marketing mix: as a tactical bolt-on, an afterthought, a place to dump discount codes when the month is looking soft.

Why Text Marketing Gets Underestimated

There is a version of this channel that most marketers have seen: a generic “FLASH SALE 20% OFF” message sent to an entire list on a Tuesday afternoon, with no segmentation, no context, and no follow-through. That version works occasionally, which is enough to keep people doing it. But it is not text marketing used strategically. It is a blunt instrument applied to a precision tool.

The underestimation usually comes from two places. First, marketers who came up through email or paid media often treat SMS as a secondary channel with a lower ceiling. Second, the brands that have used it badly have created a cultural bias against it, both internally and among consumers who have been trained to expect nothing interesting from a brand text.

I spent a significant portion of my early career fixated on lower-funnel performance. Conversion rates, cost per acquisition, return on ad spend. Those metrics felt real because they were trackable and they moved in response to what we did. What I missed for longer than I would like to admit was how much of that performance was simply capturing intent that already existed. Text marketing, when it is used well, does something different. It creates moments. It reaches people at the right time with the right message and moves them from passive to active. That is a meaningfully different job to do, and it requires a meaningfully different approach.

If you are thinking through how text marketing fits into a broader commercial plan, the Go-To-Market and Growth Strategy hub covers the wider strategic context that makes channel decisions like this one land properly.

What Makes Text Marketing Different From Other Channels

The mechanics are simple. A customer opts in, you send them messages, they read them or they do not, they buy or they do not, they stay subscribed or they opt out. What makes SMS structurally different from email or social is the intimacy of the medium. Text messages land in the same place as messages from family and friends. That is not a metaphor. It is a physical reality that shapes how people respond.

Open rates for SMS are consistently high across the industry, not because the channel is magic, but because people have not yet been fully conditioned to ignore it the way they have been conditioned to ignore promotional emails. That window will not stay open indefinitely. Brands that flood their lists with irrelevant messages are already narrowing it.

The other structural difference is consent. To receive your messages, someone has had to actively opt in. That is a much stronger signal than someone who clicked a Facebook ad or opened a cold email. An SMS subscriber has raised their hand. They want to hear from you. The question is whether what you send them justifies that decision.

There is also a speed element that matters commercially. Text messages are read quickly, often within minutes of delivery. That makes the channel genuinely useful for time-sensitive communications, limited availability, event reminders, and real-time updates. It is not useful for long-form storytelling or complex product explanations. Knowing what the channel is built for is half the strategic work.

The List Quality Problem Nobody Talks About Enough

Most brands with underperforming SMS programmes have a list quality problem, not a messaging problem. They have grown their subscriber base through aggressive pop-ups, low-value incentives, and opt-in flows that attract people who want a one-time discount and nothing else. That produces a list that looks healthy by size and performs poorly by every other metric.

I have seen this pattern play out repeatedly across retail and e-commerce clients. The team celebrates hitting 50,000 SMS subscribers. Engagement is poor, opt-outs are high, and revenue per message is disappointing. The instinct is to send more messages or improve the copy. The actual problem is that a large portion of the list was never going to be genuinely valuable, because the acquisition method selected for people who wanted a discount, not people who wanted a relationship with the brand.

List quality starts at acquisition. If you offer a 15% discount to anyone who opts in, you will attract discount hunters. If you offer early access to new products, you will attract people who are genuinely interested in what you sell. The incentive you use to build your list shapes the audience you end up with. That audience then determines what your engagement metrics look like for months or years.

Segmentation compounds this. A well-segmented list of 10,000 engaged subscribers will outperform a flat list of 100,000 mixed-intent contacts almost every time. Segmentation does not have to be complicated. Purchase history, category interest, geographic location, and engagement recency are enough to meaningfully improve relevance. Relevance is what keeps people subscribed and reading.

Tools like Hotjar can help you understand how people are interacting with your opt-in flows on-site, which gives you useful data about where your list is coming from and what those visitors were doing before they subscribed. That behavioural context is often more useful than the demographic data most brands obsess over.

The Frequency and Relevance Equation

There is no universal answer to how often you should text your customers. The right frequency depends on your category, your audience, and the quality of what you are sending. A brand that sends one genuinely useful message per week will retain subscribers better than a brand that sends four mediocre ones. That is not a controversial claim. It is a description of how people behave when something stops being worth their attention.

The frequency mistake I see most often is treating the SMS calendar the same way brands treat their email calendar, filling it up to justify the investment in the platform, rather than asking whether each message is earning its place. Text messages that feel intrusive do not just get ignored. They get opted out of. And unlike email, where someone might just stop opening your messages, an SMS opt-out is permanent. You cannot re-engage that subscriber through the same channel.

Relevance is the other half of the equation. A message that is relevant does not feel intrusive even at higher frequency. A message that is irrelevant feels intrusive even at low frequency. The brands that get this right are the ones that think about what the customer needs to know right now, not what the brand needs to say this week.

Transactional messages are the easiest win here. Order confirmations, shipping updates, appointment reminders. These messages are expected, welcomed, and read. They also build a baseline of trust that makes your promotional messages land better when you do send them. Brands that only use SMS for promotions are missing the relationship-building potential of the channel entirely.

Where Text Marketing Fits in a Go-To-Market Plan

The brands that use text marketing most effectively treat it as one part of a coordinated system, not a standalone channel. That means thinking about what role SMS plays relative to email, paid media, and organic content, and being deliberate about which jobs each channel is best suited for.

SMS is well suited for: time-sensitive offers, back-in-stock alerts, event reminders, loyalty programme updates, and post-purchase communications. It is poorly suited for: brand storytelling, complex product education, and anything that requires more than a few seconds of attention to process.

When I was running agency teams managing multi-channel campaigns for retail clients, the question we always came back to was: what is this channel’s specific job? Not “how do we use every channel we have access to” but “what does this channel do better than anything else, and are we using it for that?” SMS almost always had a clear answer: speed and directness. When we respected that, results improved. When we tried to make it do things it was not built for, it underperformed and the team lost confidence in it.

There is a useful parallel here to how growth-oriented brands think about channel experimentation. The ones that succeed are not the ones trying everything simultaneously. They are the ones that identify where their specific audience is most reachable and most responsive, and then build depth in those channels before expanding.

Text marketing earns its place in a go-to-market plan when it is used to reach people who have already demonstrated interest, at moments when they are most likely to act. That is a narrow but genuinely valuable job. Trying to make it do more than that is usually where the strategy breaks down.

The broader strategic thinking behind channel selection and go-to-market planning is something I cover in depth across the Growth Strategy section of The Marketing Juice. If you are making decisions about where to invest your marketing resource, that is worth reading alongside this.

The Compliance Layer You Cannot Ignore

Text marketing operates within a legal framework that is more demanding than email. In most markets, that means explicit opt-in consent, clear identification of the sender, an easy opt-out mechanism in every message, and restrictions on the times you can send. Getting this wrong is not just a reputational risk. It carries real financial penalties.

In the United States, the Telephone Consumer Protection Act governs most commercial SMS. In the UK and Europe, GDPR and the Privacy and Electronic Communications Regulations apply. The specifics vary by jurisdiction, but the underlying principle is consistent: you need clear consent, and you need to honour opt-outs immediately.

The compliance layer is not where most brands fail, because the major SMS platforms have made it relatively straightforward to stay within the rules. Where brands do fail is in treating compliance as the ceiling rather than the floor. Being legally compliant does not mean you are treating your customers well. You can tick every regulatory box and still send messages that are irrelevant, poorly timed, and damaging to the relationship.

Consent quality matters as much as consent itself. Someone who opted in via a buried checkbox during checkout has technically consented, but they are not the same as someone who actively signed up for your SMS programme because they wanted to hear from you. The former will opt out at the first message they do not find useful. The latter will stay engaged for months. Both are legally valid. Only one is commercially valuable.

Measuring Text Marketing Without Fooling Yourself

The metrics most brands track for SMS are click-through rate, conversion rate, and revenue per message. These are reasonable starting points, but they are easy to game in ways that make the channel look better than it is.

Sending a 40% discount code to your entire list will produce strong conversion numbers. It will also erode your margins, train your customers to wait for discounts, and tell you very little about whether your SMS programme is actually building commercial value over time. I have seen this pattern create a false sense of confidence in the channel, followed by confusion when the list starts shrinking and the discounts have to get bigger to produce the same results.

The metrics that tell a more honest story are opt-out rate over time, revenue from non-discounted messages, and the proportion of your SMS revenue that comes from customers who would not have bought without the text. That last one is genuinely hard to measure, which is why most teams do not bother. But it is the most important question: is this channel creating demand, or is it just capturing purchases that were going to happen anyway?

This is the same measurement problem that exists across performance marketing more broadly. Attribution models tend to credit the last touchpoint, which flatters channels that sit close to conversion and obscures the contribution of everything upstream. SMS sits close to conversion by design, which means it will often look better than it deserves to in a last-click model, and occasionally worse than it deserves to when it is doing relationship-building work that converts later through a different channel.

Honest approximation is more useful than false precision here. Track what you can, interpret it with appropriate scepticism, and make decisions based on patterns over time rather than individual campaign results. A single high-performing SMS blast proves very little. A programme that consistently drives engagement and retention over six months proves quite a lot.

What Good Text Marketing Actually Looks Like

The brands that use SMS well share a few common characteristics. They are selective about what they send. They segment their lists with genuine care. They treat the channel as a privilege rather than an entitlement. And they measure success by the health of the relationship over time, not just the revenue from the last campaign.

Concretely, that means a message that is relevant to the recipient, sent at a time that makes sense, with a clear and honest call to action, and a tone that sounds like a brand worth hearing from. It sounds straightforward. It is surprisingly rare.

The copy discipline required for SMS is also different from email. You have a very small amount of space to say something worth reading. That constraint is actually useful. It forces clarity. If you cannot explain why someone should care about your message in 160 characters, you probably have not thought clearly enough about why you are sending it.

Personalisation helps, but it does not have to be sophisticated. Using a customer’s first name, referencing a recent purchase, or acknowledging a preference they have expressed is enough to make a message feel less generic. The bar for “this feels relevant to me” is not as high as most brands assume. People are not expecting brands to know everything about them. They are just hoping the brand has thought about them at all.

Timing matters more than most brands account for. Sending a restaurant promotion at 11am on a Tuesday will outperform the same message sent at 9pm on a Sunday. Sending a travel offer on a Monday morning, when people are back at their desks and thinking about their next break, will outperform the same offer sent mid-week. These are not complicated insights. They require thinking about when your customer is most receptive, which requires thinking about your customer as a person rather than a contact record.

Creator-led campaigns have also started to find a place in SMS strategy, particularly for brands with younger audiences. Go-to-market approaches that incorporate creators can drive SMS opt-ins during high-intent moments like product launches or seasonal campaigns, where the creator’s audience is already primed and the opt-in feels like access rather than marketing.

The Bigger Picture

Text marketing is not going to solve a product problem. It is not going to fix a brand that customers do not trust or a value proposition that does not resonate. I have worked with enough businesses over the years to know that the ones reaching for new channels when results are disappointing are often the ones with more fundamental issues that a new channel will not address.

If your customers are not buying from you, the question worth asking first is whether the product, the experience, or the positioning is the problem. If those things are working, then SMS is a genuinely powerful tool for deepening relationships with the customers who already like you and reaching new ones at moments of high intent. If those things are not working, no amount of well-timed text messages will compensate.

The brands that get the most from text marketing are the ones that already have something worth saying. They use the channel to amplify a relationship that exists, not to manufacture one that does not. That distinction sounds obvious. In practice, it is the line between a programme that grows over time and one that slowly exhausts itself.

Scaling any channel well requires the same foundations that BCG’s research on scaling agile organisations points to: clarity of purpose, disciplined prioritisation, and the willingness to stop doing things that are not working. SMS programmes that scale successfully are almost always the ones where someone has made a deliberate decision about what the channel is for and held that line even when the temptation to use it as a quick revenue lever was strong.

Growth strategy is about building systems that compound over time, not optimising individual tactics in isolation. Text marketing, at its best, is one component of a system like that. Understanding how it connects to the rest of your commercial strategy is what separates the brands using it well from the ones wondering why their list keeps shrinking.
