SMS marketing for small business: a practical starter guide
How small businesses start text message marketing the right way — getting consent, picking a number, writing the first campaign, and measuring what it actually earns.
·7 min read
Most small businesses already have the two things text message marketing needs: a list of customers who like them and something worth telling those customers about. What they usually lack is a compliant way to send it and a habit of doing it consistently.
This guide walks through the full setup in the order it actually happens — consent, number, first campaign, measurement — so you can go from nothing to a working channel in about a week.
Start with consent, not with the message
Every legitimate text program begins with permission. Before you write a single campaign you need a place where customers actively opt in — a checkbox at checkout, a keyword they text to your number, a form on your site — and a record of when and how they agreed.
That record is what protects you if anyone ever complains, and it is also what keeps your list healthy. A list of 400 people who asked to hear from you outperforms a list of 4,000 scraped contacts every single time, because the scraped list generates complaints and complaints get your number filtered.
- ✓Ask for the number and the permission in the same step
- ✓State clearly what you will send and roughly how often
- ✓Store the timestamp, source, and exact wording of the opt-in
- ✓Include opt-out instructions in your first message to every new contact
Pick the right number and register it
A local 10-digit number is the right default for most small businesses — it looks familiar, it can take replies, and customers can call it back. Whatever you choose, it has to be registered for business messaging through 10DLC before you send at any volume, or carriers will silently filter your traffic.
Registration takes business details you already have: legal name, EIN, address, website, and a description of what you plan to send. Do it before you build the list, not after your first campaign disappears.
Write the first campaign like a person, not a billboard
The best-performing small business texts read like a note from someone the customer knows. Lead with the useful part, keep it under 160 characters, and give exactly one thing to do. Cut the branding preamble — your name belongs in the message, but not as the first six words.
Send during business hours, never before 8am or after 9pm in the recipient time zone, and start with one campaign a month rather than one a week. You can always add frequency later; you cannot un-annoy someone who already opted out.
Key takeaways
- →Collect explicit opt-in and store the proof before you send anything.
- →Register your number for 10DLC up front or your messages get filtered.
- →Keep the first text short, human, and limited to one clear action.
- →Start at a low frequency and increase only when replies stay healthy.

Frequently asked questions
Is SMS marketing worth it for a small business?
Yes, for most local and service businesses it is the highest-response channel available. Texts are typically opened within minutes and reply rates run far above email, so even a small opted-in list can drive meaningful bookings or sales at a very low cost per message.
How do I legally text my customers?
You need express written consent from each contact before sending marketing texts, a registered business number, clear opt-out instructions, and immediate processing of any opt-out request. Keep records of when and how each person consented.
How many texts per month should a small business send?
Two to four messages per month suits most small businesses. Fewer and customers forget who you are; more and opt-out rates start climbing unless every message is genuinely useful.
