SMS Marketing: What It Is, How It Works & Best Practices
July 12, 2023
Last updated: August 2026 | Written by SimpSocial
SMS marketing gives businesses a direct way to reach customers through text messages. From limited-time promotions and lead follow-ups to personalised offers and re-engagement campaigns, SMS can support customers throughout the buying journey.
Effective SMS marketing involves more than sending promotional texts. Businesses need permission-based contact lists, relevant messages, good timing, clear calls to action and a way to measure results.
This guide explains what SMS marketing is, how it works, its benefits, examples, compliance considerations and best practices.
What Is SMS Marketing?
SMS marketing is a permission-based mobile marketing strategy that uses text messages to send promotions, offers, updates and other marketing communications directly to customers’ mobile phones.
SMS stands for Short Message Service. Marketing texts can encourage customers to visit a website, claim an offer, schedule an appointment, reply to a message or take another action.
SMS marketing is also commonly called text message marketing or text marketing.
Unlike channels where a business competes for attention in a feed, SMS delivers communication directly to a customer’s messaging inbox.
How Does SMS Marketing Work?
A typical SMS marketing campaign follows this process:
- A customer opts in. They agree to receive marketing texts.
- The contact enters an SMS list. Businesses can organise contacts by interests, behaviour or buying stage.
- A campaign is created. This may be a promotion, follow-up or announcement.
- The message is sent. SMS can be immediate, scheduled or automated.
- The customer takes action. They may click, reply, book or buy.
- Results are measured. Campaign data helps improve future messages.
For dealerships in particular, dealership sales automation can connect lead activity with structured follow-up, CRM workflows and appointment booking rather than relying on employees to manually send every message.
SMS Marketing Vs Business SMS
SMS marketing and business SMS are closely related, but they are not identical.
| SMS Marketing | Business SMS |
|---|---|
| Focuses on marketing and engagement | Covers wider business communication |
| Includes promotions and offers | Includes support and notifications |
| Encourages customer action | Can be informational |
| Often part of marketing automation | Can support sales, service and operations |
Business SMS is the broader category. SMS marketing is one way businesses use texting to generate opportunities and engage customers.
Types of SMS Marketing Campaigns
Businesses can use SMS at several stages of the customer journey.
Promotional SMS
Promote discounts, events or limited-time offers.
Example:
Save 15% this weekend. View the offer before Sunday: [link]. Reply STOP to opt out.
Welcome Messages
Confirm a customer’s subscription and explain what types of messages they can expect.
Lead Follow-Ups
Follow up when someone submits an enquiry, requests information or shows interest in a product or service.
Businesses managing large lead volumes can use CRM technology to automate customer follow-ups while maintaining customer context and consistent communication.
Re-Engagement Campaigns
Reconnect with customers or leads who have stopped interacting with the business.
Loyalty Campaigns
Send exclusive promotions, early access or personalised offers to existing customers.
Product and Event Campaigns
Announce products, inventory, events or new services to relevant subscribers.
Benefits of SMS Marketing
Direct Communication
SMS provides a direct channel to customers who have chosen to receive messages.
Fast Delivery
It works well for time-sensitive offers, reminders and follow-ups.
Personalisation
Contacts can be segmented according to customer interests, activity or buying stage.
Automation
Automated workflows can respond to customer activity and trigger relevant follow-ups.
Two-Way Conversations
SMS can start conversations rather than operate only as a broadcast channel.
Supports Other Marketing Channels
SMS works alongside email, advertising, social media and CRM activity. A broader automotive dealership marketing strategy can connect SMS with social advertising, CRM automation, lead generation and sales follow-up.
What Are the Disadvantages of SMS Marketing?
SMS requires careful management.
Potential drawbacks include:
- Excessive messages can feel intrusive
- Businesses need to manage consent
- Messages offer limited space
- Poor segmentation creates irrelevant communication
- SMS creates messaging costs
- Excessive promotions can increase opt-outs
A permission-based strategy focused on relevance helps reduce these problems.
How to Start SMS Marketing
Follow these steps:
- Define your campaign goal.
- Choose an SMS or customer engagement platform.
- Build a permission-based subscriber list.
- Segment your contacts.
- Write a concise message.
- Add one clear call to action.
- Choose an appropriate sending time.
- Automate relevant follow-ups.
- Measure campaign results.
- Improve future campaigns using the data.
Businesses that manage leads through an automotive sales CRM can connect messages with customer history, lead sources, appointments and follow-up activity instead of managing texting separately.
How to Build an SMS Marketing List
Your SMS list should consist of people who have knowingly agreed to receive messages.
Businesses can collect subscribers through:
- Website forms
- Landing pages
- Checkout forms
- QR codes
- In-store promotions
- Social media
- Keyword-based sign-ups
Explain what customers are signing up for before collecting consent.
Following clear SMS opt-in and opt-out guidance can help businesses build permission-based lists and manage unsubscribe requests properly.
Avoid buying mobile-number lists. Permission-based contacts create a stronger foundation for engagement and compliance.
SMS Marketing Best Practices
Get Permission First
Make sure you have the required consent before sending marketing texts.
Identify Your Business
Customers should know immediately who sent the message.
Provide Value
Send useful offers, information and relevant updates rather than constant promotions.
Keep Messages Concise
Make the purpose and next action clear.
Use One Main CTA
Give the customer one obvious action to take.
Personalise and Segment
Use customer information and behaviour to make messages more relevant.
Manage Frequency
Avoid overwhelming subscribers with unnecessary communication.
Automate Carefully
Automation should improve timing and relevance, not produce repetitive messaging.
For dealerships, AI texting for car dealerships can support structured follow-up based on lead status, previous activity and dealership workflows.
SMS Marketing Compliance and Consent
SMS marketing is permission-based, and businesses need to consider the telecommunications, privacy and marketing rules that apply to their campaigns.
Good practices include:
- Obtain appropriate consent
- Explain what messages customers will receive
- Keep consent records
- Provide an easy way to opt out
- Process opt-out requests promptly
- Maintain suppression records
- Respect customer communication preferences
- Follow requirements applicable to each market
Automotive businesses should also understand automotive CRM texting compliance and how consent, customer preferences and communication records should be managed through dealership systems.
Requirements vary by jurisdiction, message type and sending method. Businesses should review the laws and industry requirements that apply to their campaigns.
How to Measure SMS Marketing Performance
Useful SMS marketing metrics include:
| Metric | What It Measures |
|---|---|
| Delivery rate | Messages successfully delivered |
| Click-through rate | Recipients clicking a link |
| Response rate | Recipients replying |
| Conversion rate | Recipients completing an action |
| Opt-out rate | Subscribers leaving the list |
| Revenue | Sales attributed to SMS |
| ROI | Return compared with campaign cost |
Match the metric to the campaign goal. An appointment campaign, for example, should not be evaluated in the same way as an ecommerce promotion.
SMS Marketing Vs Email Marketing
SMS and email serve different purposes.
| SMS | |
|---|---|
| Concise communication | Longer content |
| Useful for timely messages | Strong for detailed nurturing |
| Highly direct | Supports richer layouts |
| Limited content space | More room for information |
| Good for immediate actions | Good for longer journeys |
Businesses often benefit from using both channels rather than treating them as competitors.
SMS Marketing for Car Dealerships
SMS can be particularly useful in automotive sales because customers often move between online research, advertising, text conversations and dealership visits.
Dealerships can use SMS for:
- New lead responses
- Vehicle enquiries
- Appointment scheduling
- Test-drive reminders
- Lead nurturing
- Customer re-engagement
- Promotional campaigns
- Sales follow-ups
The strongest approach connects SMS to CRM data. An AI Automotive CRM can connect customer information, conversations, follow-up and sales workflows in one environment.
How SimpSocial Supports Customer Engagement

Rather than treating SMS as an isolated communication tool, dealerships can connect texting with lead information, customer conversations and sales workflows.
This helps sales and BDC teams maintain consistent communication throughout the buying journey while using automation where it adds value.
Make SMS Part of the Customer Journey
Effective SMS marketing is not about sending the greatest number of texts. It is about communicating with the right customer at a useful moment.
Start with permission, segment contacts, keep messages relevant and measure the results. When SMS is connected with CRM data, automation and customer engagement workflows, businesses can create more consistent communication from the first enquiry through conversion and beyond.
