SMS Marketing Statistics: 30+ Verified Data Points for 2026

This briefing assembles verified statistics on SMS and text-message marketing, drawing a hard line between two very different kinds of data: probability-sample survey research from the Pew Research Center on how Americans actually use texting, and self-reported benchmark figures published by SMS marketing vendors. The distinction matters because the most-quoted SMS statistic, a “98% open rate,” is vendor-sourced and cannot be independently verified, since SMS has no open-tracking mechanism. Every number below carries its publisher, year, geography, and a link to the source.

Executive Summary

• About 91% of U.S. adults owned a smartphone as of the Pew Research Center Mobile Fact Sheet, and 98% owned a cellphone of some kind (Pew Research Center, United States, fact sheet updated 2024-2025).
• Texting is the dominant mobile behavior: in Pew’s last dedicated texting survey, 73% of U.S. adult cell owners sent and received texts, with a median of 10 texts per day and an average of 41.5 (Pew Research Center, United States, 2011).
• Consumer opt-in to business SMS is high and rising by vendor surveys: 84% of U.S. consumers reported being opted in to business texts (SimpleTexting, 2025 survey of 1,000 U.S. consumers) and 86% in a parallel survey (EZ Texting, 2025 report, n=1,074).
• The widely cited “98% open rate” for SMS is vendor-sourced and not independently verifiable; SMS has no native open tracking, so the figure is a delivery estimate rather than a measured open rate (Rally Corp analysis, 2024).
• Gartner has published SMS open and response rates “as high as 98% and 45%,” against 20% and 6% for email, the original source of the most-repeated SMS marketing claim (Gartner for Marketers).
• Klaviyo’s benchmark dataset, drawn from over 183,000 customers, found SMS flows generate 45.2% of total SMS revenue from just 7.6% of sends (Klaviyo, 2026 benchmarks).
• The global application-to-person (A2P) SMS market generated roughly $48 billion in 2022 and is forecast to reach about $78 billion by 2027 (Statista, global).
• U.S. SMS marketing now operates under tighter consent rules: the FCC’s revised TCPA opt-out rule took effect April 11, 2025, requiring businesses to honor opt-outs sent by any reasonable method within 10 business days (FCC / legal analysis, United States, 2025).

Key Findings

• 91% of U.S. adults owned a smartphone and 98% owned a cellphone of some kind (Pew Research Center, Mobile Fact Sheet, United States, 2024-2025).
• Smartphone ownership reached 97% of U.S. adults under 50, 90% of those 50 to 64, and 78% of those 65 and older (Pew Research Center, United States, 2024-2025).
• 73% of U.S. adult cell owners sent and received text messages, sending or receiving a median of 10 and an average of 41.5 messages on a typical day (Pew Research Center, United States, 2011).
• U.S. cell owners aged 18 to 24 exchanged an average of 109.5 texts on a normal day, more than 3,200 per month (Pew Research Center, United States, 2011).
• 31% of U.S. texting adults preferred texts to voice calls while 53% preferred a voice call, but among heavy texters (50+ per day) 55% preferred texting (Pew Research Center, United States, 2011).
• 84% of surveyed U.S. consumers were opted in to receive texts from businesses, up roughly 35% from a few years earlier (SimpleTexting, United States, 2025 survey, n=1,000).
• 86% of surveyed U.S. consumers opted in for business texts, a 20% increase since 2021 (EZ Texting, United States, 2025 report, n=1,074).
• 82% of surveyed consumers reported checking texts within five minutes and about 32% within 60 seconds (SimpleTexting, United States, 2025).
• The top three reasons consumers opted in were appointment and reservation reminders (76%), shipment and order updates (68%), and promotions or sale alerts (58%) (SimpleTexting, United States, 2025).
• 53% of consumers who unsubscribed cited texting too frequently as the primary reason (SimpleTexting, United States, 2025).
• Gartner reported SMS open and response rates as high as 98% and 45%, versus 20% and 6% for email (Gartner for Marketers, United States).
• SMS flows accounted for just 7.6% of sends but drove 45.2% of total SMS revenue across Klaviyo’s customer base (Klaviyo, 2026 benchmarks, 183,000+ customers).
• 79% of surveyed consumers said they were more likely to purchase when subscribed to a business’s texts, up 21% from 2024 (EZ Texting, United States, 2025 report).
• The TCPA carries statutory damages of $500 to $1,500 per violation with a private right of action, the core legal risk in U.S. SMS marketing (FCC / legal analysis, United States, 2025).
• The global A2P SMS market generated about $48 billion in 2022 and is forecast to reach roughly $78 billion by 2027 (Statista, global).

How Americans Use Texting: The Probability-Sample Baseline

The only large, nationally representative U.S. data on texting behavior comes from the Pew Research Center, which uses probability sampling rather than opt-in panels. These figures describe the population, not a marketer’s subscriber list, and they set the ceiling on how reachable SMS audiences can be.

About 91% of U.S. adults owned a smartphone and 98% owned a cellphone of some kind (Pew Research Center, Mobile Fact Sheet, United States, updated 2024-2025). Smartphone ownership was near-universal among younger adults at 97% for those under 50 (Pew Research Center, United States, 2024-2025). The share of Americans who are smartphone-dependent, meaning they rely on a phone for online access without home broadband, grew from 8% in 2013 to 16% (Pew Research Center, United States, 2024-2025).

On texting specifically, Pew’s most detailed dedicated survey found that 73% of adult cell owners sent and received text messages, with a median of 10 texts and an average of 41.5 texts on a typical day (Pew Research Center, United States, 2011, n=2,277 adults). Among 18-to-24-year-olds the average was 109.5 texts per day (Pew Research Center, United States, 2011). The clearest limitation in this section is age: Pew’s granular texting-volume study dates to 2011, so the volume figures are historical, while the ownership figures are current. Treat the 2011 numbers as a behavioral baseline, not a 2026 measurement.

Consumer Opt-In and Texting Behavior: Vendor Survey Data

More recent consumer-behavior data comes from SMS platform vendors. These are real surveys with disclosed sample sizes and dates, but they are commissioned by companies that sell texting software, so they should be read as directional rather than as neutral government statistics.

SimpleTexting surveyed 1,000 U.S. consumers and 400 business owners and marketers between December 23 and 26, 2024, and reported that 84% of consumers were opted in to business texts (SimpleTexting, United States, 2025). In the same survey, 82% said they check texts within five minutes and roughly 32% within 60 seconds, and 71% wanted the ability to text a business back (SimpleTexting, United States, 2025). EZ Texting’s parallel report, based on 1,074 qualified U.S. respondents surveyed November 1 to 15, 2024, found 86% opted in for business texts, a 20% rise since 2021, and 79% more likely to purchase when subscribed (EZ Texting, United States, 2025 report). The two vendor surveys agree within two points on the headline opt-in figure, which is a useful cross-check, though both share the same commercial incentive.

Open Rates, Response Rates, and the “98%” Problem

This is the most misunderstood area in SMS marketing. The “98% open rate” appears in nearly every vendor blog post, but SMS has no equivalent of email’s tracking pixel, so there is no technical way to measure whether a text was opened.

Gartner is the most credible origin for the figure: it reported SMS open and response rates “as high as 98% and 45%,” compared with 20% and 6% for email (Gartner for Marketers, United States). Independent analysts argue the 95-to-98% figure is best understood as a delivery rate, not a measured open rate, because carriers confirm delivery but not opens (Rally Corp analysis, 2024). The practical conclusion is that SMS is genuinely high-attention, but the precise “98% open” number should be presented as a vendor and analyst estimate, flagged as not independently verifiable, never as a measured metric. The 45% response rate is similarly Gartner-attributed and widely re-quoted without a fresh underlying study.

Campaign Performance Benchmarks

For performance metrics that are actually measurable, click rate, conversion, and unsubscribe rate, the largest disclosed datasets come from Klaviyo, whose benchmarks aggregate performance across its customer base.

Klaviyo’s 2026 benchmarks, drawn from over 183,000 customers, found that automated SMS flows achieved click rates near 10% on average, nearly double campaign performance, with top performers above 16% (Klaviyo, 2026 benchmarks). SMS flows accounted for just 7.6% of sends yet drove 45.2% of total SMS revenue, and 64.4% of that flow revenue came from new buyers (Klaviyo, 2026 benchmarks). These figures describe Klaviyo customers, who skew toward e-commerce, so they are not representative of all SMS programs, and “click rate” definitions vary by platform, which limits cross-vendor comparison.

Market Size and Marketer Adoption

The global A2P (application-to-person) SMS market, which includes marketing, alerts, and one-time passcodes, generated roughly $48 billion in 2022 and is forecast to reach about $78 billion by 2027 (Statista, global). Independent market-research firms publish materially different totals depending on scope, with 2025 estimates ranging from about $52 billion to $79 billion, so the absolute number should be treated as approximate and methodology-dependent. On adoption, 75.3% of surveyed businesses reported using SMS marketing and 65.4% planned to increase texting budgets (SimpleTexting, United States, 2026 survey, n=400 businesses).

Compliance and TCPA Context

SMS marketing in the United States is governed by the Telephone Consumer Protection Act (TCPA) and FCC rules, and the legal framework shifted in 2025. Marketing texts require prior express written consent (FCC / legal analysis, United States, 2025). The FCC’s revised opt-out rule took effect April 11, 2025, requiring businesses to honor opt-out requests sent by any reasonable method, not only keyword replies, and to process them within 10 business days (FCC / legal analysis, United States, 2025). Separately, the FCC’s stricter “one-to-one consent” rule was vacated by the 11th Circuit in Insurance Marketing Coalition v. FCC and is not in effect (legal analysis, United States, 2025). The financial stakes are defined by statute: the TCPA allows $500 to $1,500 per violation with a private right of action (FCC / legal analysis, United States, 2025). This is the single most important reason published opt-in and engagement rates cannot be taken at face value as a license to text broadly.

Original Synthesis

1. The reachability ceiling versus the opt-in claim. Pew’s 91% smartphone ownership figure (United States, 2024-2025) sets the maximum reachable share of U.S. adults, while vendor surveys report 84% to 86% consumer opt-in (SimpleTexting and EZ Texting, United States, 2025). Multiplying the two as an illustrative bound suggests roughly 76% to 78% of U.S. adults are theoretically reachable and opted in (0.91 x 0.84 to 0.91 x 0.86). Limitation: the opt-in figures come from opt-in survey panels and refer to “any business,” not a single sender, so the real per-brand reachable audience is far smaller; this is a ceiling, not an estimate of any campaign’s list.

2. The open-rate gap, quantified. Combining Gartner’s email figures (20% open, 6% response) with its SMS figures (98% open, 45% response) yields a roughly 4.9x open-rate multiple and a 7.5x response-rate multiple in SMS’s favor (Gartner for Marketers). Logic: 98/20 = 4.9 and 45/6 = 7.5. Limitation: both SMS figures are vendor and analyst estimates, not measured opens, so the multiples describe the marketing narrative, not an audited reality; the email figures are themselves channel-wide estimates.

3. The flow concentration ratio. Using Klaviyo’s 2026 benchmarks, dividing revenue share by send share for SMS flows (45.2% of revenue from 7.6% of sends) gives a concentration ratio of about 5.9, meaning automated flow messages are nearly six times more revenue-efficient per send than the average SMS (Klaviyo, 2026). Limitation: this reflects Klaviyo’s e-commerce-heavy customer base and Klaviyo’s own attribution model, so it should not be generalized to all SMS programs or to non-retail use cases.

Charts to build

1. U.S. smartphone ownership over time. Data: Pew ownership 35% (2011) to 91% (2024-2025). Source: Pew Research Center. Insight: near-universal device penetration is the foundation of SMS reach. Citation-worthy because it is primary, probability-sample data.
2. SMS vs email: open and response rate (flagged as estimate). Data: 98%/45% vs 20%/6%. Source: Gartner. Insight: the channel-advantage narrative. Citation-worthy with the caveat that SMS figures are estimates, which makes a more honest chart than vendor versions.
3. Klaviyo flow concentration: send share vs revenue share. Data: 7.6% of sends, 45.2% of revenue. Source: Klaviyo 2026. Insight: automation drives disproportionate revenue. Citation-worthy because it is from a large measured dataset.
4. Consumer opt-in growth, two-vendor comparison. Data: 84% (SimpleTexting) and 86% (EZ Texting), both 2025. Source: vendor surveys. Insight: cross-vendor agreement strengthens the directional claim. Citation-worthy as a transparency device.
5. TCPA compliance timeline. Data: opt-out rule effective April 11, 2025; one-to-one rule vacated 2025. Source: FCC. Insight: the regulatory tightening behind consent practices. Citation-worthy for legal accuracy.

Methodology

Sources were selected on a strict hierarchy: probability-sample survey research (Pew Research Center) and government and regulatory bodies (FCC) ranked highest; established market-research firms (Statista, Gartner) next; vendor benchmark reports with disclosed sample sizes and dates (Klaviyo, SimpleTexting, EZ Texting) treated as directional and labeled as vendor-sourced. We excluded any statistic we could not trace to a named publisher with a real URL. Where the famous “98% open rate” appeared, we attributed it to Gartner and explicitly flagged that SMS has no native open-tracking, so the figure is an estimate, not a measurement. Where market-size figures conflicted across firms, we cited the Statista A2P series and noted the wider range from other firms rather than picking a single precise number. Pew’s 2011 texting-volume figures are presented as a historical baseline, clearly dated, alongside current ownership figures. Conflicting numbers were handled by reporting both and noting the discrepancy. Last updated June 2026.

Source Quality

Tier 1 (primary, government, probability-sample): Pew Research Center (Mobile Fact Sheet; Americans and Text Messaging, 2011); U.S. FCC rules and TCPA framework.

Tier 2 (credible market research and analyst firms): Statista (A2P SMS market revenue); Gartner for Marketers (SMS open and response rate figures).

Tier 3 (vendor benchmark reports and expert commentary): Klaviyo 2026 SMS benchmarks; SimpleTexting 2025 and 2026 statistics; EZ Texting 2025 report; Rally Corp analysis of the open-rate myth; reputable legal commentary on the 2025 TCPA rule changes.

Most Quotable Statistics

• “91% of U.S. adults own a smartphone, up from 35% in 2011.” (Pew Research Center, 2024-2025)
• “The 98% SMS open rate is an estimate, not a measurement: SMS has no open tracking.” (Gartner figure; Rally Corp analysis, 2024)
• “SMS flows drive 45.2% of SMS revenue from just 7.6% of sends.” (Klaviyo, 2026)
• “84% to 86% of surveyed U.S. consumers are opted in to business texts.” (SimpleTexting and EZ Texting, 2025)
• “The TCPA carries $500 to $1,500 in damages per violation, with a private right of action.” (FCC / TCPA, 2025)

Data Limitations

Pew’s detailed texting-volume figures are from 2011 and are historical, while its ownership figures are current. The headline “98% open rate” and “45% response rate” are vendor and analyst estimates that cannot be technically measured for SMS. Opt-in and adoption figures come from vendor-commissioned surveys of opt-in panels, which carry commercial incentive and refer to “any business,” not a single sender. Market-size totals vary widely across research firms by scope and methodology. Klaviyo benchmarks reflect an e-commerce-skewed customer base and Klaviyo’s own attribution. None of these figures should be read as audited financial data.

Press Summary

Text-message marketing rests on near-universal device adoption: about 91% of U.S. adults own a smartphone, and texting remains one of the most-used mobile behaviors (Pew Research Center, 2024-2025). Vendor surveys put consumer opt-in to business texts at 84% to 86% (SimpleTexting and EZ Texting, 2025), and Klaviyo’s benchmark data shows automated SMS flows generating 45.2% of SMS revenue from only 7.6% of sends (Klaviyo, 2026). The most-quoted statistic, a “98% open rate,” originates with Gartner but cannot be independently measured because SMS lacks open tracking; it is best treated as a delivery-based estimate. The legal backdrop tightened in 2025, when the FCC’s revised TCPA opt-out rule took effect on April 11, requiring businesses to honor opt-outs sent by any reasonable method within 10 business days, against statutory damages of $500 to $1,500 per violation. For marketers, the data supports SMS as a high-attention channel while cautioning against quoting unverifiable engagement numbers. See CO Consulting for the underlying source set.
