Customer engagement is a term that has been so thoroughly emptied of meaning by repeated misuse that using it feels almost embarrassing. Every dashboard at every company has an engagement number. Almost none of them measure whether the customer actually wants to hear from you. They measure whether your message arrived, whether someone’s thumb accidentally grazed a link, whether an email client auto-loaded a tracking pixel. These are logistics metrics. We have been dressing them up as relationship metrics for twenty years, and the gap between the two is where most marketing budgets quietly disappear.

A genuine engagement signal is one that requires the customer to respond, redeem, and return. An open rate, by contrast, is evidence only that your message wasn’t filtered. The average inbox receives over 100 emails a day. The psychological adaptation humans have made to that volume is to process email with a kind of ambient, automatic dismissal: not this, not this, not this, maybe this later, delete. We have trained ourselves to apply almost no attention to most of what arrives. Email marketers have known this for years; their response has been to send more email, which accelerates the problem. It is the kind of solution that makes quarterly numbers look fine while the underlying asset of customer attention is being depleted.

By the numbers: Text Message open rate: 98% vs. ~20% for email. Median time to read a text after receipt: 3 minutes. Text Message response rate: 45% vs. ~6% for email.

The numbers above are not particularly controversial and you’ve heard us expound on the superpower that is Text Messaging in many past blogs on Mobiniti. They’ve been reproduced across enough studies that the finding is solid even if individual figures vary slightly by source. What is controversial is the question of why companies with access to these numbers haven’t restructured their engagement programs accordingly. The honest answer is probably a combination of inertia, tooling investment, and the particular human tendency to stick with what is measurable even when what’s measurable isn’t what matters. Email is comfortable. Its metrics are familiar. Its failure modes are invisible.

The consent is not the constraint. That is the point. A subscriber who opted into texts is a different kind of relationship than someone who checked a pre-ticked box in 2021 and has been ignoring your newsletters since.

Text Messaging does something structurally different. The 98% open rate reflects a categorically different relationship between the medium and attention. Text messages occupy a space in people’s lives that is still, for now, associated with things that matter: people they know, information they requested, alerts they asked for. That association erodes fast when companies abuse it.

The performance gap between Text Messaging and email is largest not in open rates, but in response and conversion. Studies consistently show Text Messaging click-through rates running 6 to 8 times higher than email equivalents, with the gap widening further for time-sensitive offers and transactional messages. Texts arrive where people are already engaged, rather than in channels people tune out.

The implication for how you build a Text Message program is specific. The businesses that consistently outperform with Text Messaging share a few structural features. They use segmentation seriously, which means building it around purchase history, location, and engagement tier, not just “all subscribers.” And they treat two-way messaging as a feature, not an edge case. A customer who can reply to a text and get a real response is having a fundamentally different experience than a customer who receives a broadcast. The former builds something; the latter, builds nothing in the long run.

Text Message remains meaningfully under-adopted relative to its performance data. In most categories, receiving a well-timed, relevant text from a business is still slightly surprising. The bar for standing out is lower than it will be in two or three years, when more businesses have caught up. Permission-based contact lists don’t scale through money; they scale through sustained good behavior over time, which means the businesses building them now will have something that later entrants cannot simply purchase. Whether that window remains open for another year or five is genuinely uncertain. 

The spiciest point, and the one I’d push back on if someone told me Text Messaging was “just another channel,” is that the opt-in requirement that is a constraint is actually where most of the value lives. Requiring explicit consent to text a customer creates a list that is structurally different from every other contact list a company holds. Everyone on it made a deliberate choice. That choice is an asset. Opt-in consent is deliberately designed as a barrier to entry — strict regulations govern it, and getting it wrong doesn’t just cost a marketer a segment of their clientele; it can cost them the entire channel. But for those who navigate it correctly, the reward is a list that is incredibly easy to squander by treating the channel like a louder email list, and incredibly effective when treated as the thing it is: a small group of people who said, directly, that they want to hear from you. Building a business communication strategy around that signal, rather than around the noisier and less meaningful signals of email, is a customer relationship decision. The channel is just where it happens to be playing out.

Mobiniti is built for Text Message programs that treat the opt-in as an asset. With segmentation, two-way messaging, and behavior-based automation that actually earns the attention customers give you. www.mobiniti.com
