SMS segmentation guide to personalized messaging
Group your audience by behavior, location, and more to send personalized messages that boost conversions and customer retention. Explore the full guide to learn how.

Think about a restaurant where the staff remembers your go-to dish and starts preparing it as soon as you walk in. That same personalized experience is exactly what SMS segmentation brings to your marketing. It’s a smarter way to use your communication channels to connect with customers.
Let’s break down how to use message segmentation to build effective marketing campaigns and drive better results.
What is SMS segmentation?
SMS segmentation is the practice of grouping your subscriber list into smaller, targeted SMS segments. You can create SMS segments based on behavior, location, age, purchase history, or engagement. Whether it’s a special offer, update, or loyalty reward, relevant messages make customers more likely to engage.
Imagine selecting clothing that fits each customer’s unique style. You wouldn’t recommend the same outfit to a teenager, a business executive, or a marathon runner. You would choose styles that match their needs and preferences.
With message segmentation, you send content your audience wants to see, improving your chances they’ll read, click, and convert.

Why segmentation matters
Generic messages don’t work anymore, especially when customers expect relevance and personalization.
Here’s why SMS segmentation is a must:
- Higher engagement: Targeted SMS texts get more opens, clicks, and responses.
- Boosted conversions: Personalized calls to action guide users toward taking the next step: buying, signing up, or sharing.
- Lower opt-out rates: People are less likely to unsubscribe when they’re receiving texts that feel tailored to them.
- Better ROI: With smarter targeting, you spend less and get more value per marketing campaign.
- Optimized message length: After creating a segment, keep SMS messages within 160 characters. You’ll also know when to send longer texts for better storytelling.
Smart ways to segment your SMS subscribers
Here are the top methods for message segmentation:
1. Behavior-based segmentation
Segment subscribers by what they do: clicking links, browsing products, or completing purchases.
Example: If someone views a product but doesn’t buy, follow up with a reminder or special offer.
2. Purchase history
Segment subscribers based on their past purchases.
Example: Send relevant accessory offers to customers who previously purchased a dress. You can also automatically add repeat buyers to a loyalty program.
3. Location-based segmentation
Use the subscriber’s city or region to tailor your message.
Example: Promote weather-appropriate products based on where someone lives, or send geo-specific event invites.
4. Demographics
Segment by age, gender, or income level when appropriate.
Example: Younger audiences prefer texts with emojis and pop culture references. Older ones prefer clear, simple messages with fewer characters.
5. Engagement level
Group subscribers by how often they interact with your SMS texts.
Example: Send re-engagement SMS campaigns to subscribers who haven’t interacted in the past 30 days. Active users may get longer messages with exclusive content.
Top SMS segmentation strategies
- Capture cart abandoners: Segment users who started the buying process but left items in their cart. Send timely reminders, exclusive discounts, or product recommendations to encourage them to finalize their order.
- Convert new SMS subscribers: Create a welcome series for new subscribers. Send a friendly greeting, a first-time offer, and useful brand info to turn new sign-ups into loyal customers.
- Re-engage inactive customers: Identify subscribers who haven’t interacted with you in a while. Target them with special reactivation offers, updates on new arrivals, or a simple “We miss you!” message to help bring them back.
- Reward loyal shoppers: Create a segment of your top buyers and send them early sale access, VIP deals, or loyalty rewards. This not only shows appreciation but also encourages continued engagement and repeat purchases.
- Personalize by purchase history: Review customer buying history to offer tailored product tips or reminders when items run low.
How Rappi achieved growth with SMS segmentation
Rappi, a leading Latin American delivery app, grew to over 700,000 users in just a year. All thanks to using message segmentation through our powerful segmentation and automation solution.
Rappi created SMS segments based on customer behavior, such as late-night snackers or parents ordering baby supplies. They then sent personalized SMS text offers that connected with each group. When customers stopped placing orders, they received messages with tailored discounts or restock reminders, increasing retention.
Result: A campaign with 2,000 segmented SMS messages for a chicken restaurant generated 150 orders in one hour.
Best practices for effective SMS segmentation
You can begin without investing in complex tools. Just follow these proven tips:
- Begin with basic segments: Split your list into simple groups: new, active, and inactive users.
- Check your character count: SMS texts allow up to 160 characters per message. Stay concise or send longer messages via MMS or linked landing pages.
- Use the right phone number format: Standardize numbers so you’re sending to valid subscribers who can receive messages.
- Test often: Run A/B tests on your marketing campaigns by segment to optimize content, character limit, and timing.
- Follow SMS compliance: Only send to opted-in users and provide a way to stop receiving texts. Always follow TCPA and GDPR guidelines.
- Collect data over time: Gather details like preferences or birthdays through progressive profiling.
Better SMS segmentation – better results
When you group your audience into smart SMS segments, every message becomes more relevant, more timely, and more effective. This approach helps brands turn simple texts into powerful customer moments.
