Almost every American adult carries a phone that receives texts. DataReportal counted 417 million cellular mobile connections in the United States in late 2025, equal to about 120% of the population, since many people carry more than one line or device (DataReportal, Digital 2026). Reach is not the problem. Whether SMS is effective for your business depends on what you send, to whom and how often.
Why texts get noticed
A text arrives on the lock screen, without a promotions tab or spam folder competing for attention, and it is read in seconds. That immediacy is the main strength of SMS, and also its main risk. Americans guard their text inbox closely, and an irrelevant message is more likely to trigger a STOP reply than an ignored email.
Use cases that tend to perform in the US
Retail and e-commerce
Short windows reward texting: a Black Friday early-access code, a Cyber Monday reminder a few hours before a deal ends, or a back-in-stock alert. Keep emails for the full product story and use SMS as the nudge.
Appointments and services
Dentists, salons, auto repair shops and home-service companies use reminders to cut no-shows. These are often informational rather than marketing messages, but you still need the customer’s consent to text them, and a clean way to opt out.
Restaurants and local businesses
A slow Tuesday offer, a July 4 cookout special or a game-day menu can fill tables the same evening. Our restaurant solutions show how to combine this with email.
Nonprofits and events
Last-minute venue changes, severe-weather cancellations and GivingTuesday reminders all suit a brief text.
Where SMS is the wrong tool
Long content, detailed product comparisons, newsletters and anything that needs images belong in email. Frequency matters too: texting several times a week quickly erodes goodwill. Our article on texting versus email helps you divide the work, and combining SMS and email campaigns shows how the channels support each other.
The legal cost of getting it wrong
Effectiveness disappears quickly if a campaign breaks the Telephone Consumer Protection Act. Marketing texts need prior express written consent, and damages of $500 to $1,500 per message add up fast across a list. Carriers also filter traffic that is not registered through A2P 10DLC, toll-free verification or a short code, so a campaign that looks sent may never arrive. Read our guide to SMS marketing in the US before your first send.
How to measure whether it works
- Delivery rate: check that messages reach handsets; Mailpro’s SMS statistics show status per number.
- Response or redemption: use a unique code or tracked link in each campaign so sales can be attributed.
- Opt-out rate: a rising number of STOP replies signals that frequency or relevance needs work.
- Revenue per message: compare it with the cost of each send, since you pay per text.
Making each text count
Start with your brand name, since US texts come from a number rather than a sender name. State one offer or piece of information, include a single link and end with opt-out wording. Personalize with the recipient’s first name or appointment time using personalized SMS, and schedule for mid-morning or early evening in the recipient’s own time zone.
In Mailpro’s own customer survey, users rate SMS deliverability 9.8/10. Start small: test a single segment of your US list, measure the response, then scale up.
