SMS Marketing Statistics 2026: 110+ Open and CTR Data

Delivery and Deliverability

Delivery is the foundation of every other SMS metric. A non-delivered message cannot be opened, clicked, or attributed to revenue. Two years after the 10DLC rollout stabilized, US delivery rates have settled into a tight band -- but the variance between vetted and non-vetted senders remains large.

Open Rate Reality and Methodology

The single most-cited SMS statistic is the 93-98% open rate. It is also the most misleading. SMS preview text is visible from the device lock screen, which means the carrier's delivery confirmation and the device's notification expansion are conflated with active reading in most vendor reporting. Treating the SMS open rate as comparable to an engaged email open is a category error that will misallocate spend.

What the data actually shows: 93-98% of delivered SMS messages are structurally exposed to the recipient within three minutes (Attentive, Postscript, Klaviyo benchmarks all converge on this band). Whether the recipient mentally engaged with the content is a separate question -- and for that, click-through rate is the only useful proxy.

CTR Benchmarks by Program

Click-through rate is the operational metric for SMS. Median CTR varies more than 3x between the highest-performing programs (ecommerce flash promotions) and the lowest (B2B services). Use the following benchmarks as floor-and-ceiling references when auditing existing programs or projecting performance for new ones.

CTR by Message Type

• Abandoned cart: 18.4% median CTR (highest of any automated flow); first message within 30 minutes of abandonment outperforms 1-hour and 24-hour delays by 2.1x.
• Welcome series: 14.7% median CTR; offer-based welcomes outperform brand-introduction welcomes by 1.8x.
• Post-purchase: 11.9% median CTR (shipping updates, review requests, replenishment).
• Win-back: 6.2% median CTR; programs that segment by last-purchase recency outperform blast win-backs by 2.4x.
• Promotional broadcast: 9.3% median CTR; segmentation by purchase history lifts CTR 1.6x over unsegmented sends.
• Replenishment / subscription reminder: 13.6% median CTR; among the highest-RPS automated flows.
• Loyalty / VIP tier alerts: 10.2% median CTR; critical for retention in DTC and beauty.
• Back-in-stock: 21.7% median CTR -- the single highest-performing transactional SMS type.

Revenue-Per-Send Benchmarks

Revenue-per-send (RPS) is the cleanest single metric for SMS program health -- total attributed revenue divided by messages sent. Unlike CTR, it captures both engagement and average order value; unlike total revenue, it normalizes for list size. The benchmarks below use 7-day click-through attribution windows, which is the standard across Klaviyo, Postscript, and Attentive reporting.

Original Analysis: Why RPS Is Plateauing in Mature Stacks

Across our agency portfolio and the public Klaviyo and Postscript datasets, ecommerce SMS revenue-per-send has flattened year-over- year for the first time in five years. The proximate explanation is what practitioners call the "everyone has SMS" effect: in 2019, an SMS subscriber was self-selected into a small, high-intent cohort that converted aggressively because the channel was novel and the brand had earned an explicit invitation. By 2026, SMS lists for mature DTC brands routinely exceed 40% of the email list size, and the marginal subscriber acquired in 2025-2026 is materially less responsive than the 2019-2022 cohort. List composition has regressed toward the mean of the broader email audience.

The implication for RPS forecasting is structural: brands modeling SMS growth on legacy multipliers ($1.50+ RPS as a planning assumption) are over-projecting. The new realistic floor for mature ecommerce brands is $0.65-$0.90 RPS for promotional broadcasts, with automated flows still doing the heavy lifting ($2-$4 RPS). The competitive frontier has moved from "do you have SMS" to "how aggressively are you segmenting and how cleanly are your automated flows recovering revenue email cannot reach in time."

Opt-Out Rates and List Health

Opt-out rate is SMS's leading indicator. Unlike email unsubscribes, SMS opt-outs are immediate and binding -- once a subscriber sends STOP, you cannot legally re-engage them without a fresh explicit opt-in. Healthy programs treat opt-out rate as a governance metric, not a vanity one.

Opt-Out Rate by Frequency Tier

• 1-3 messages/month: 0.21% median opt-out per send; 0.7% monthly cumulative.
• 4-6 messages/month: 0.32% per send; 1.4% monthly. The optimal range for most ecommerce brands.
• 7-9 messages/month: 0.58% per send; 2.6% monthly. Diminishing returns become visible.
• 10+ messages/month: 0.71% per send; 3.4%+ monthly. List degradation accelerates and RPS typically declines despite higher absolute revenue.

Opt-Out by Vertical

• Healthcare: 0.21% per send (lowest; high-intent subscribers).
• Finance and banking: 0.28% per send.
• DTC subscription: 0.34% per send.
• Beauty and personal care: 0.39% per send.
• Ecommerce broad: 0.42% per send.
• Hospitality: 0.51% per send.
• Flash-sale apparel: 0.84% per send (highest; promotional fatigue).

List Growth and Opt-In Tactics

Opt-in source is the single largest determinant of long-term subscriber value. Subscribers acquired through high-intent paths (checkout opt-in, abandoned-cart triggers, keyword-to-text campaigns from owned channels) materially outperform those acquired through low-friction paths (sweepstakes, paid quiz funnels) on both CTR and RPS.

Conversion Rates by Opt-In Source

• Checkout opt-in (post-purchase): 38.4% capture rate of customers who reach checkout; highest LTV cohort.
• Email + SMS combined pop-up: 9.7% site visitor conversion to dual subscriber; up from 3.2% for SMS-only pop-ups.
• Two-step pop-up (email then SMS): 6.4% SMS conversion of email subscribers; preferred for premium brands.
• Keyword-to-text from social bio: 1.8-3.4% follower-to-SMS conversion depending on platform.
• QR codes (in-store, packaging): 12.7% scan-to- opt-in rate; strong for omnichannel retail.
• Abandoned-cart trigger (email-to-SMS upgrade): 22.1% upgrade rate from email subscribers who abandon cart twice.
• Paid social lead ads: 0.4-1.1% click-to-opt-in; cheapest CAC but lowest LTV.
• Sweepstakes / giveaway: 14.6% page conversion but 4.8x higher 90-day churn vs other sources.

CAC Benchmarks by Opt-In Source

• Checkout opt-in: $0 incremental CAC (organic from existing customers).
• Site pop-up: $0.18-$0.42 fully loaded CAC per SMS subscriber.
• Paid social lead ads: $1.80-$4.20 per SMS subscriber.
• Sweepstakes / giveaway: $0.60-$1.40 per subscriber but 4.8x higher churn.
• QR codes (in-store): $0.05-$0.18 per subscriber depending on attribution model.

For sustained list growth, the highest-leverage tactic is layering checkout opt-in on top of a two-step site pop-up. This combination captures both the high-intent post-purchase cohort and the broader site visitor cohort without crowding either flow.

Cross-channel context matters too -- a sound SMS list-growth program complements broader lead generation benchmarks and conversion rate benchmarks that govern the rest of your funnel.

RCS Business Messaging Adoption

RCS (Rich Communication Services) is the carrier-supported successor to SMS. After Apple shipped iOS 18 with interoperable RCS in late 2024, the channel finally has the cross-platform reach to justify mainstream brand investment. The 2026 numbers establish RCS Business Messaging as a credible 2027 marketing channel, though it is not yet ready to replace SMS programs.

RCS Capabilities That Drive the Lift

• Verified-sender branding: Brand name, logo, and verified checkmark in the message header.
• Rich cards and carousels: Native product imagery, multi-product carousels, in-message pricing.
• Suggested replies: Single-tap quick-reply buttons reduce friction for customer-service deflection.
• Read receipts and typing indicators: Enables two-way conversational commerce flows that SMS cannot support.
• File attachments: PDFs, video, and high- resolution imagery without third-party hosting.

10DLC Compliance and Automation Flows

10DLC (10-digit long code) is now the dominant messaging type for US application-to-person SMS. Registration with The Campaign Registry is mandatory for any brand sending more than minimal volume. Costs and throughput allocations vary by vetting tier.

10DLC Cost and Throughput Tiers

• Standard (non-vetted): $4 brand registration, no vetting fee, 75 MPS throughput cap, ~92% delivery rate.
• Standard vetted: $40 vetting fee, 150-225 MPS, ~95% delivery rate.
• Low-volume vetted: $40 vetting, 75 MPS, optimized for low-volume transactional senders.
• High-volume vetted: $1,500 vetting, up to 2,400 MPS, ~97% delivery.
• Top-tier (Charity, Government, Carrier-approved): $3,000 vetting, up to 4,500 MPS, ~98% delivery.
• Monthly campaign fee: $1.50-$10 depending on use case (low-volume mixed, marketing, account notifications).
• SHAFT-restricted content: Sex, hate, alcohol, firearms, tobacco -- additional carrier scrutiny regardless of vetting tier.

Lifecycle Automation Flow Performance

• Welcome series (3 messages over 7 days): 14.7% CTR, $2.18 RPS, 22% of new-subscriber 30-day revenue.
• Abandoned cart (3 messages over 24h): 18.4% CTR, $3.94 RPS, recovers 11.2% of abandoned-cart revenue email cannot reach in time.
• Browse abandonment (1 message at 3h): 13.6% CTR, $2.71 RPS.
• Post-purchase (4 messages over 30 days): 11.9% CTR, $1.41 RPS, drives 14% of repeat-purchase revenue.
• Win-back (3 messages over 21 days): 6.2% CTR, $0.74 RPS, recovers 8.4% of churned subscribers when segmented by recency.
• Replenishment (1 message at predicted reorder): 13.6% CTR, $1.93 RPS, especially strong for DTC subscription.
• Birthday / anniversary: 9.4% CTR, $1.12 RPS; underused but high-intent.

SMS+Email Lifecycle

Coordinated SMS+email lifecycle programs lift customer LTV 18% over email-only equivalents. The lift is concentrated in the first 90 days post-acquisition, where SMS recovers cart-abandonment revenue email alone misses due to slower open velocity. Specific measured lifts:

• 30-day LTV lift: +14% over email-only welcome and post-purchase flows.
• 90-day LTV lift: +18% (the steady-state number).
• Repeat-purchase rate: +11.4 percentage points for SMS+email cohorts.
• Cart-abandonment recovery: +21.7% incremental recovery on top of email-only baselines.
• Customer-service deflection: SMS two-way order- status flows reduce ticket volume 14-22% for ecommerce brands.

Trends and 2027 Outlook

The 2026 SMS marketing landscape is defined by maturation rather than expansion. Most ecommerce brands have an SMS program; most programs hit 96.8% delivery; most face the same list-saturation and frequency-fatigue dynamics. The 2027 inflections that matter for planning sit in three places: RCS crossover, agentic customer experience, and CTIA/STIR-SHAKEN evolution.

Original Analysis: 2027 Projections

RCS overtakes standalone SMS as the default North-American marketing channel by Q4 2027. At current adoption pace (54% combined US smartphone reach in April 2026, tracking toward 72% by Q4 2027), RCS will cross the practical threshold where brands can run RCS-first programs with SMS fallback rather than SMS-first programs with experimental RCS. The CTR and RPS lift (1.8-2.4x and 1.4x respectively in current tests) is large enough that the channel transition will be economically forced once the reach threshold is met. Expect Klaviyo, Postscript, and Attentive to ship RCS-first authoring workflows in their 2027 product cycles.

Agentic customer experience makes SMS a deflection channel. Two-way SMS and RCS conversational commerce, powered by agentic LLM backends, will absorb a meaningful share of customer-service ticket volume that today flows into email and chat. Early pilots show 14-22% ticket deflection on order-status and shipping queries; this expands to returns, exchanges, and product-question flows in 2027. The economic implication is that SMS RPS will need to be measured alongside support-cost deflection, not just direct revenue. STIR/SHAKEN and CTIA evolution will continue to tighten the carrier filtering apparatus, particularly for political and non-marketing-purpose senders. Expect tighter content classification, faster carrier blocking of suspect campaigns, and additional vetting fees for higher-throughput tiers.

Conclusion

SMS marketing in 2026 is a maturing channel where the structural metrics (96.8% delivery, 93-98% open rate) are stable but the economic frontier (RPS, opt-out, list growth) is competitive. Brands that win in 2026 are not the ones with the largest SMS lists -- they are the ones running tightly segmented automated flows with subscriber-level frequency caps, coordinated SMS+email lifecycle programs, and disciplined opt-in source mix. RCS is the 2027 inflection to plan for, not the 2026 channel to bet the program on.

The benchmarks in this collection should serve as planning floors and ceilings, not as targets. Most operational levers (segment tightness, flow coverage, frequency discipline, send-time routing) move RPS more than channel choice does. Build the lifecycle stack first, layer RCS pilots on top, and measure RPS net of opt-out and CAC -- not headline open rate.
