Text Marketing Works Better When You Stop Treating It Like Email

Text marketing is one of the highest-performing channels most brands still use badly. Open rates are genuinely exceptional, response windows are short, and the audience is opted in by definition. The problem is not the channel. The problem is that most marketers approach SMS the same way they approach email: volume-first, personalisation-last, with a creative brief that could have been written in 2009.

Done well, text marketing creates a direct, low-friction line between your brand and your customer at the moment they are most likely to act. Done badly, it burns through your most valuable marketing asset, which is permission, faster than almost any other channel.

Why Text Marketing Gets Misunderstood From the Start

I spent years watching clients treat every new channel the same way. A new format would emerge, someone in the room would say “we should be doing this,” and within six weeks the team had replicated their existing approach inside the new format. Email strategy became social strategy became push notification strategy. And now it becomes SMS strategy.

The instinct is understandable. You have existing assets, existing messaging hierarchies, and existing workflows. Rebuilding from scratch is expensive. But text is a fundamentally different medium and it punishes the copy-paste approach more than most.

Email sits in an inbox that people check on their own schedule. A promotional email sent at the wrong time might get ignored. An SMS sent at the wrong time gets read immediately, creates friction, and gets the sender blocked. The asymmetry between upside and downside is steeper with text than with almost any other channel in your mix.

Part of this sits within a broader go-to-market challenge. Many brands struggle to sequence their channels effectively, and text is often an afterthought rather than a deliberate choice. If you are thinking more carefully about how your channels fit together, the Go-To-Market and Growth Strategy hub covers the underlying frameworks worth having in place before you add another channel to the plan.

What Makes Text Marketing Different From Every Other Channel

Three things separate SMS from the rest of your channel mix, and all three cut both ways.

The first is immediacy. Most text messages are read within minutes of receipt. That is not a marketing claim; it is a function of how people relate to their phones. This makes SMS genuinely powerful for time-sensitive communications: flash sales, appointment reminders, shipping updates, limited-availability offers. But it also means there is no “I’ll deal with that later” buffer. If your message is irrelevant or poorly timed, the recipient experiences that irritation in real time.

The second is intimacy. A phone number feels more personal than an email address. People give out their mobile number selectively. When someone opts into your SMS programme, they are extending a level of trust that is qualitatively different from subscribing to a newsletter. That trust is the asset. The message is secondary.

The third is constraint. You have 160 characters in a standard SMS. Even with MMS or longer message formats, the medium rewards brevity. This is actually a discipline that improves marketing. When you cannot hide behind three paragraphs of context, you are forced to get to the point. The brands that do text well have usually done the harder creative work of knowing exactly what they want to say and why it matters to the recipient right now.

The Compliance Foundation You Cannot Skip

Before anything else: compliance is not a box-ticking exercise. In the United States, the Telephone Consumer Protection Act carries per-message fines that can compound quickly at scale. In the UK and Europe, GDPR and the Privacy and Electronic Communications Regulations set clear requirements around consent. If you are operating across markets, the requirements stack up fast.

The practical requirements are not complicated, but they are non-negotiable. You need explicit opt-in consent, which means the subscriber understood they were signing up for marketing messages specifically. You need a clear opt-out mechanism in every message. You need to honour opt-outs immediately. And you need to keep records of consent in a form you could produce if challenged.

I have seen brands treat compliance as a legal department problem rather than a marketing operations problem. That is a mistake. The people building your SMS flows need to understand the rules, not just the legal team. When someone builds an automated trigger sequence without thinking through consent at each touchpoint, the legal team finds out about it at the worst possible time.

The good news, if you want to call it that, is that strong compliance practice and strong marketing practice point in the same direction. Both require you to be precise about who is in your audience, what they consented to, and whether what you are sending them is genuinely relevant. Brands that take compliance seriously tend to run better SMS programmes, not just safer ones.

How to Build an SMS List That Is Actually Worth Having

List size is a vanity metric in text marketing more than in almost any other channel. An SMS list of 50,000 disengaged subscribers who barely remember opting in will underperform a list of 8,000 people who signed up because they genuinely wanted early access to your sales or real-time delivery updates.

The quality of your list is determined almost entirely by how you built it. The worst lists come from checkbox consent buried in terms and conditions, from incentive-driven opt-ins where the subscriber wanted the discount and not the ongoing messages, and from list acquisition practices that should not exist at all. The best lists come from clear, specific value propositions at the point of sign-up.

When I was running agency accounts for retail clients, we tested opt-in messaging extensively. The lists built around vague promises (“sign up for exclusive offers”) churned faster and engaged less than lists built around specific utility (“get a text when your order ships” or “be first to know when this item is back in stock”). The second category of subscriber had a reason to stay opted in beyond the initial incentive.

Practical list-building approaches that hold up include: post-purchase opt-in flows where the value is transactional and clear; in-store sign-ups with staff who can explain what the subscriber will receive; website pop-ups timed to purchase intent rather than entry; and keyword opt-in campaigns where the subscriber actively texts a word to a shortcode. Each of these produces a subscriber who made a deliberate choice, which is the foundation of a list worth having.

What to Send and When to Send It

Most SMS programmes fail on frequency before they fail on content. Brands that start well, with a clear value proposition and a warm list, often erode both within six months by increasing send frequency without increasing relevance. The subscriber who was delighted to get a shipping update and a monthly flash sale alert becomes someone who is getting three messages a week and is looking for the opt-out link.

There is no universal right frequency. It depends on your category, your audience, and what you have actually committed to at the point of opt-in. A restaurant running a daily lunch special can send daily if that is what subscribers signed up for. A furniture retailer sending weekly promotional messages is almost certainly over-sending.

What tends to work is a tiered content model. Transactional messages, which include order confirmations, shipping updates, appointment reminders, and password resets, carry the highest engagement and the lowest opt-out risk. They are also the easiest messages to write because the value is self-evident. Triggered messages, which are sent based on specific subscriber behaviour such as a cart abandonment or a product back-in-stock alert, perform well because the timing is inherently relevant. Promotional messages, which are the broadcast campaigns most brands default to, require the most discipline because they are the most likely to feel intrusive.

Timing within the day matters more than most brands account for. Messages sent during commuting hours, lunch, and early evening tend to outperform those sent early morning or late at night. But the more important timing variable is relevance to the individual, not the clock. A behavioural trigger sent at 9am because the subscriber just abandoned a cart will outperform a perfectly timed broadcast sent to your entire list at 12pm.

Writing SMS Copy That Does Not Sound Like a Brand

The constraint of 160 characters is where most brand voices collapse. The formal, carefully hedged language of brand guidelines does not survive the translation to SMS. What works in text marketing sounds more like a message from a person than a message from a company.

This does not mean abandoning your brand. It means understanding which elements of your brand translate to short, direct, conversational copy and which do not. A brand with a warm, informal tone of voice will find SMS easier than a brand that has built its identity around considered, long-form communication. Neither is better; they just require different amounts of translation.

The structural requirements of a good SMS are simple: identify who you are immediately (because the sender ID is not always visible), state the value or the reason for the message in the first ten words, include a single clear action if one is required, and make the opt-out path visible. That is it. Any message that cannot be structured around those four elements probably should not be an SMS.

Links in SMS messages deserve specific attention. Shortened URLs look like spam and reduce trust. Where possible, use branded short domains. And be honest about where the link goes. A subscriber who clicks expecting a discount and lands on a generic homepage will not click again.

Segmentation: The Difference Between Relevant and Intrusive

One of the consistent findings from my time managing large-scale performance programmes across multiple verticals is that segmentation almost always improves results more than creative optimisation does. The right message to the wrong audience is a waste. The right message to the right audience, even if the creative is imperfect, tends to work.

In SMS, segmentation is not optional at any meaningful scale. Sending the same message to your entire list treats a first-time buyer the same as a customer of three years, treats someone who bought last week the same as someone who has not purchased in eight months, and treats a subscriber in Manchester the same as one in Miami. None of that makes commercial sense.

The segments that tend to matter most for SMS are: purchase recency and frequency, which tells you how engaged the customer currently is; product category affinity, which tells you what they are likely to be interested in; geographic location, which matters for local offers, events, and time-zone-appropriate send times; and engagement with previous SMS messages, which tells you how receptive this subscriber is to the channel itself.

You do not need sophisticated data infrastructure to do basic segmentation. Most SMS platforms allow you to filter by purchase date, location, and engagement history. Start with those three variables and you will already be ahead of the majority of brands using the channel.

Measuring Text Marketing Without Fooling Yourself

SMS reporting is subject to the same measurement problems that affect every marketing channel, and in some ways it is worse because the conversion window is so short that attribution looks cleaner than it is.

Open rates and click-through rates are useful directional metrics but they do not tell you whether the message drove incremental revenue or just captured demand that would have happened anyway. This is the same question I spent years asking about lower-funnel performance channels more broadly. A customer who was already planning to buy and happened to receive an SMS before doing so does not represent a sale generated by SMS. It represents a sale that SMS received credit for.

The most honest way to measure SMS is through holdout testing. Send to 80% of an eligible segment and withhold from 20%. Compare conversion rates between the two groups over a defined window. The incremental lift is your actual channel contribution. It is more work than looking at click-to-conversion rates, but it is the only measurement approach that tells you what the channel is actually doing rather than what it is claiming.

Opt-out rate is also a metric that deserves more attention than it gets. A rising opt-out rate is a leading indicator of a programme that is losing the trust of its subscribers. Most brands track it but few treat it as a serious signal. If your opt-out rate ticks up after a specific campaign type or a change in frequency, that is the channel telling you something worth listening to.

For a broader view of how to build measurement frameworks that give you honest signals rather than flattering ones, tools like those covered at Semrush’s growth toolkit overview can be a useful starting point, though the principles of honest attribution apply regardless of the platform you are using.

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

Text marketing is a retention and conversion channel by nature. It works on audiences who already know you. It is not well-suited to building awareness among people who have never heard of your brand, and attempts to use it that way tend to produce the worst outcomes: low engagement, high opt-out, and reputational damage in a channel that depends on trust.

This means its role in your go-to-market plan should be clearly defined. SMS is most valuable in the middle and lower sections of your funnel: re-engaging lapsed customers, converting high-intent prospects who have already interacted with your brand, supporting time-sensitive promotions to a warm audience, and maintaining a relationship with your best customers between purchases.

Where brands get into trouble is treating SMS as a substitute for upper-funnel investment rather than a complement to it. If your acquisition channels are not working, adding more SMS messages to your existing base will not fix the problem. It will just accelerate the erosion of the audience you already have.

The brands I have seen use text most effectively tend to have a clear view of the customer lifecycle and a deliberate answer to the question of what role SMS plays at each stage. They are not sending texts because they have a list and a platform. They are sending texts because there is a specific moment in the customer relationship where a direct, immediate message adds genuine value.

There is also an interesting intersection between SMS and creator-led campaigns, particularly for time-sensitive product launches or seasonal promotions. The combination of creator-driven awareness and SMS-driven conversion can be effective when the audience overlap is right. Later’s work on creator-led go-to-market approaches is worth reviewing if you are thinking about how to sequence those channels.

The growth frameworks covered at Crazy Egg are also useful context for understanding how SMS fits within a broader conversion optimisation approach, particularly if you are building automated flows that interact with other touchpoints.

The Mistakes That Kill SMS Programmes Early

After watching a lot of SMS programmes get built and a fair number of them get abandoned, the failure modes are consistent enough to be worth naming directly.

The first is over-sending in the first 30 days. Brands often front-load their SMS programmes with welcome sequences, onboarding messages, and early promotional pushes. The subscriber experiences this as an immediate flood of messages and opts out before the programme has had a chance to demonstrate its value. A slower, more considered welcome sequence almost always produces better long-term retention.

The second is treating opt-out as a failure rather than as useful information. When subscribers opt out, the instinct is to optimise the opt-out rate down without asking why it went up. The question worth asking is what changed. Was it a new message type? A frequency increase? A campaign that felt off-brand? The opt-out rate is a signal about the quality of the programme, not just a number to minimise.

The third is building SMS in isolation from the rest of the customer communication stack. If your email team and your SMS team are running independent calendars, your best customers are getting promotional messages from both channels simultaneously with no coordination. That is not a customer experience; it is a scheduling collision. The channels need to be planned together, with clear rules about which message type belongs in which channel and what happens when both fire at once.

The fourth, and probably the most common, is launching without a clear answer to the question of what value the subscriber is getting from staying opted in. If you cannot articulate that value in one sentence, your subscribers will not be able to either, and they will find the opt-out link eventually.

Building a text marketing programme that actually holds up over time is fundamentally the same challenge as building any other retention programme. You are asking someone to maintain a relationship with your brand, and that relationship needs to deliver something worth having. The channel is just the mechanism. The thinking that makes it work is the same thinking that makes any customer-facing programme work: genuine understanding of what the customer needs and honest discipline about whether you are delivering it.

If you want to think about how SMS fits within a wider growth strategy, the articles in the Go-To-Market and Growth Strategy hub cover the channel-agnostic principles that apply regardless of which platform you are building on.
