Email inboxes are crowded, social feeds are pay-to-play, and your customers carry the one channel they actually read within minutes. Text messaging has the highest attention of any marketing channel available to a small business, and it does not require a big budget or a marketing team to do well. What it does require is a plan: how you collect numbers, what you send, and how you stay on the right side of the rules.
Why SMS Works for Small Businesses
A text message lands directly on the lock screen. There is no algorithm deciding whether your customer sees it, no spam folder swallowing it, no subject line to agonize over. For local and small businesses, that directness is the whole game: a restaurant filling slow Tuesday tables, a salon filling last-minute cancellations, a retailer moving seasonal stock.
It is also cheap. Per-message costs are measured in cents, and many campaigns pay for themselves with a handful of redemptions. Before you start, it helps to model the math with a bulk SMS cost calculator so you know what a campaign to your list size will actually cost.
Step 1: Build Your List the Right Way
Everything in SMS marketing rests on consent. You may only text people who have clearly agreed to receive your marketing messages, and “clearly” has a specific meaning: an affirmative opt-in, not a pre-checked box, not a phone number collected for another purpose.
Practical ways small businesses collect opt-ins:
- A keyword and short code or number on receipts, table tents, and signage (“Text JOIN to 555123 for 10% off your next visit”)
- A website popup or form with explicit SMS consent language separate from email signup
- Point-of-sale signup where staff ask customers directly
- A QR code linking to a mobile signup form
Whatever method you use, the opt-in language must name your business, say messages are recurring marketing texts, mention that message and data rates may apply, and explain how to opt out. Keep records of every opt-in: when it happened, where, and the exact wording shown. Those records are your protection if anyone questions your list.
Never buy a list of numbers and start texting it as if those people opted in to hear from you. Purchased numbers do not carry consent to your business, and texting them is one of the fastest ways to face complaints and legal trouble.
Step 2: Pick the Right Sending Setup
You have three main options for the number you text from:
- A 10DLC number (standard 10-digit number) is the default choice for small businesses. It supports two-way conversations and local presence, but requires 10DLC registration with your business identity and campaign details.
- A toll-free number works well if your customers are spread across the country. It needs its own verification process before you can send marketing traffic.
- A short code (those 5-6 digit numbers) is fast and memorable but expensive to lease, which puts it out of reach for most small businesses.
For most small operations, 10DLC is the sweet spot: affordable, conversational, and local-looking. Whichever you choose, complete the registration or verification before your first campaign, because carriers filter unregistered traffic.
Step 3: Write Texts People Actually Want
You get 160 characters per segment before messages split and cost you extra, so every word has to earn its place. If you are fuzzy on how length affects cost, read the SMS character limit explained guide first.
What good SMS copy looks like:
- Identify yourself immediately. “Hi, it’s Maria from Bloom Salon:” beats a mystery message every time.
- Lead with the value. The offer or information comes first, not last.
- One clear call to action. “Show this text for 15% off through Sunday” or “Reply YES to book.”
- Create genuine urgency sparingly. Real deadlines work; manufactured panic trains people to ignore you.
- Write like a person. Short sentences, no corporate filler, no shouting in all caps.
Example: “Bloom Salon: 20% off all color services this week only. Reply BOOK to grab a slot. Reply STOP to opt out.”
Notice the opt-out line. Every marketing text should include your business name and clear opt-out instructions. It is both a legal expectation and basic respect.
Step 4: Time It and Pace It
Timing matters more in SMS than in almost any other channel because a text interrupts. The general safe window is 8 AM to 9 PM in the recipient’s local time, and some states are stricter. Never text in the small hours unless the customer asked for exactly that (like an appointment reminder they scheduled).
Frequency is the other half of the equation. For most small businesses, two to four promotional texts per month is plenty. Tell subscribers what to expect at signup (“up to 4 msgs/month”) and then honor it. A list that hears from you twice a month with genuinely good offers will outperform a list you blast weekly.
Step 5: Stay Compliant Without Overthinking It
The compliance basics for a small business are not complicated:
- Consent: documented opt-in for every number, never assumed.
- Identification: your business name in every message.
- Opt-outs: honor STOP requests immediately, and accept them through any reasonable channel.
- Quiet hours: no promotional texts late at night or early morning in the recipient’s timezone.
- Content honesty: no misleading offers, no fake urgency.
This is general information, not legal advice. The underlying law is the TCPA, enforced alongside carrier rules and state laws that can be stricter. If you are ever unsure whether a campaign is compliant, check with a qualified attorney before sending.
Step 6: Measure What Matters
SMS gives you clean, honest metrics. Track:
- Delivery rate to spot list quality problems
- Click-through rate on links to judge message quality
- Redemption rate on offers to judge real business impact
- Opt-out rate per campaign; a spike tells you something about that message
- Revenue per campaign so you know the channel earns its keep
Run new campaigns through the SMS campaign checklist before sending. It catches the small mistakes, broken links, missing opt-out language, wrong timing, that quietly kill results.
Frequently Asked Questions
How much does SMS marketing cost for a small business?
Per-message costs are a few cents, plus platform fees and number registration costs. A list of a few hundred subscribers typically costs tens of dollars per campaign. Model it with a cost calculator before you commit to a platform.
How do I get customers to sign up for text alerts?
Offer something concrete in exchange: a discount, early access, or useful alerts like appointment reminders. Make signup dead simple with a keyword, QR code, or one-field form, and state the expected message frequency upfront.
Can I text customers from my personal phone number?
You can, but you should not for marketing. Personal numbers lack registration, filtering protections, opt-out handling, and scalability. Use a proper business number with 10DLC registration or toll-free verification.
How often should a small business send marketing texts?
Two to four times per month works for most businesses. Service businesses sending reminders and confirmations can message more often because those texts are expected and useful. Watch your opt-out rate; it tells you when you are overdoing it.
What is the biggest SMS marketing mistake small businesses make?
Texting people who never properly opted in. It generates complaints, risks legal exposure under the TCPA, and burns the trust that makes SMS valuable. Build the list slowly and honestly, and it will outperform any shortcut. For more planning tools, browse the free tools hub.
