Why Marketers Are Asking If SMS Is Dying

Marketers are asking if SMS is dying because their inboxes feel crowded, spam complaints are rising, and channels like WhatsApp and RCS promise richer, more engaging experiences. The concern isn’t unfounded — 58% of consumers have already unsubscribed from brand texts, and excessive frequency remains the top reason for opting out. Consumer tolerance data shows comfort with receiving two or more business messages per day dropped from 69% in 2025 to 59%, signaling a growing sensitivity to overuse.

Yet beneath these worries, SMS continues to grow in volume and adoption, challenging the idea of obsolescence. Send volume jumped 40% year-over-year in 2025 after 31% growth the prior year, and marketing use cases expanded by 34% globally. Usage trends confirm SMS remains a core channel for most businesses, accounting for 62% of Infobip’s platform traffic — nearly 389 billion interactions out of 628 billion total.

The real risk to SMS isn’t decline, but misuse. When brands blast frequent, untargeted messages, they erode trust and drive unsubscribes. But when used sparingly and intelligently — especially in automated flows like appointment reminders or lead follow-ups — SMS delivers exceptional engagement. Worqd sees this firsthand in AI SDR and lead conversion work, where timely, permission-based texts help qualify inquiries in under 60 seconds, turning interest into booked calls without adding noise. The data suggests SMS isn’t dying — it’s evolving, demanding smarter, more restrained use as part of a broader, multichannel strategy.

The Data Says SMS Is Growing, Not Dying

The numbers tell a different story than the headlines. SMS send volume surged 40% year-over-year in 2025 after 31% growth in 2024, and marketing use cases climbed 34% globally according to Omnisend and Infobip. The market is projected to reach $9.6 billion by 2030, with SMS still carrying 62% of messaging platform traffic across regions.

Engagement metrics remain striking, though they deserve honest framing. Industry sources cite 98% open rates and 45% response rates versus roughly 6% for email, with 90% of texts read within three minutes. These are widely reported industry claims rather than independently audited results — SMS doesn't send standardized read receipts the way email does. Still, the conversion data is harder to dismiss: automated SMS flows deliver 20.34% click-through rates and 0.77% conversion, dramatically outperforming broadcast campaigns at 12.39% and 0.12% respectively.

• 54% of consumers want promotional texts; only 11% of businesses send them (Lotiva)

The demand gap is real: most consumers want to hear from brands by text, but few businesses have built the systems to deliver it well. At Worqd, we see this show up in campaign cost benchmarks — the difference between a blast that burns the list and an automated sequence that books calls comes down to timing, relevance, and restraint. SMS isn't dying. It's being forced to grow up.

SMS Isn't Being Replaced — It's Being Upgraded

If you've been watching the messaging space lately, you might think SMS is on its way out. The reality is more interesting: it's being upgraded, not retired — and the channels "replacing" it are actually making it stronger.

The shift is about role, not relevance. WhatsApp now serves over 3 billion users with roughly 140 billion messages sent daily, while RCS has passed about 1.5 billion users and is accelerating since Apple added native RCS support in iOS 18. These channels are absorbing the interactive, media-rich use cases — product carousels, verified sender profiles, conversational commerce — that plain text was never designed to handle.

That doesn't leave SMS out of the picture. It remains the universal foundation, reaching 5.3 billion-plus users on 100% of mobile phones, no internet required. RCS even includes SMS fallback, so messages still land when rich features aren't supported. As Twilio's analysts put it, "For most global businesses, the answer isn't RCS or WhatsApp. It's both."

Geography shapes the split. WhatsApp dominates Latin America, Europe, and India, while SMS dominates North America — yet SMS traffic is growing in all of these regions, with Latin America up 53% and Europe up 47% in 2025. The channels are complementary: SMS guarantees delivery everywhere; WhatsApp converts deeper, with conversion rates of 45–60% versus 29% for SMS.

For marketers, the smart stack looks like this:

• SMS for universal, time-critical reach — reminders, confirmations, alerts
• WhatsApp for conversational flows and global commerce
• RCS for verified, interactive campaigns in native messaging apps

Here's the part most businesses miss: the demand gap. Research shows 54% of consumers want promotions by text, yet only 11% of businesses send them. That's a wide-open window for early movers — especially since SMS remains cheap to run, at roughly $0.01–0.05 per message in the U.S.

At Worqd, we see this play out with clients constantly: the brands that pair SMS follow-up with richer channels book more calls than those treating texting as an afterthought. The lesson is simple — match the channel to the geography and the use case, and SMS keeps earning its place as the foundation. The channel isn't dying; underuse is the real problem.

How to Run SMS That Actually Converts

If SMS is dying, nobody told the numbers — but the brands winning with it are playing a very different game than the ones blasting coupons. The difference comes down to four deliberate choices.

First, automate instead of broadcast. Omnisend's dataset of 321 million messages shows automated SMS earns a 20.34% click rate and $0.74 in revenue per message, versus 12.39% and $0.15 for one-off campaigns. Triggered texts — confirmations, reminders, quote follow-ups — do the heavy lifting; mass sends mostly burn your list.

Second, measure what pays. Sakari's candid analysis of SMS metrics points out that standard texts don't send read receipts, so open rates are largely fiction. A 95% "open rate" with zero bookings is worse than 75% with a full calendar. Report on bookings, confirmations, and revenue instead.

Third, cap frequency and segment hard. Frequency is the top opt-out trigger at 40%, and 58% of consumers have already unsubscribed from brand texts, per Infobip's messaging statistics. The reward for restraint is real: contacts who respond to at least half your texts carry 2.4x higher lifetime value than low-responders, so a targeted send to 500 engaged buyers beats a blast to 5,000.

Finally, budget honestly. Beyond per-segment costs of $0.005–$0.01, cost breakdowns from Lotiva flag carrier passthrough fees, 10DLC registration, and per-user platform charges as the line items that quietly erode ROI — plus TCPA penalties reaching $1,500 per violation if compliance slips.

Set expectations by use case, because the benchmarks vary enormously:

• Appointment reminders: 70–85% confirmation rates are realistic — one restaurant's confirmation campaign prevented 60 no-shows worth $4,200 from just $30 in send costs.
• Promotional offers: expect 18–35% response but only 5–15% booking rates.
• Quote follow-ups: 15–30% conversion targets — one plumbing company lifted bookings from 19% to 31%.
• Database re-engagement: 3–8% reactivation is a solid outcome for dormant contacts.

That spread explains why the same channel looks like a miracle to a clinic and a money pit to a retailer. Transactional and time-sensitive messages convert at multiples of promotional ones, so weight your program accordingly.

At Worqd, this is how we treat SMS inside the follow-up path — as a precision tool for turning inquiries into booked calls, not a megaphone. The channel isn't obsolete. Lazy SMS is.

The Real Risk Isn't Obsolescence — It's Overuse

The numbers tell a clear story: SMS is growing, not dying. But the same research reveals a quieter threat — the channel works so well that brands are wearing it out. That's the risk worth planning for.

Consider the tension. SMS sends grew 40% year over year in 2025 after 31% growth in 2024, according to Omnisend's data across 150,000 brands. Yet Infobip's research shows 58% of consumers have already unsubscribed from brand texts, with 45% pointing to excessive frequency as their top annoyance. The channel isn't failing. The way many teams use it is.

The economics still favor restraint. At $0.01–0.05 per message, SMS remains one of the cheapest ways to reach a buyer — and automated texts earn $0.74 in revenue per message versus $0.15 for mass campaigns. A restaurant's confirmation campaign in one Sakari case study prevented 60 no-shows worth $4,200 from just $30 in sends. Fewer, better messages win on both cost and revenue.

That leads to the practical playbook:

• Automate the moments that matter — confirmations, reminders, and quote follow-ups convert far better than broadcasts.
• Cap frequency and segment hard; frequency is the #1 opt-out trigger at 40%.
• Use SMS as your universal foundation and layer richer channels — WhatsApp or RCS — on top for interactive conversations.

There's also a follow-up angle most teams miss. A text only converts when someone answers it fast — 90% of SMS are read within three minutes, but a reply that sits unanswered for hours wastes that window entirely. As Twilio's team puts it, the question isn't which channel to pick. It's how the whole path fits together, from first click to booked call.

That's how we approach it at Worqd. SMS earns its place in a multichannel plan — paired with instant qualification and fast follow-up — rather than carrying the whole load. When every inquiry gets answered in under 60 seconds, your texts stop being noise and start being revenue.
