Sending SMS to Gen Z vs. Millennials: How their messaging preferences differ

How Gen Z and Millennials differ in SMS marketing 

SMS gives e-commerce brands a direct way to reach customers, making it particularly useful for time-sensitive offers, product updates, abandoned-cart reminders, and retention campaigns. 

While Gen Z and Millennials share many digital habits, their expectations aren't identical. Gen Z has grown up in a highly mobile, social-first environment, while Millennials experienced the transition from more traditional forms of communication to smartphones, social media, and digital commerce.

Generational marketing can help identify broad differences in how Gen Z and Millennials engage with SMS, but it should serve as a guide rather than a fixed set of rules. These insights can help inform messaging strategies, while customer behavior should remain the stronger signal for deciding what to send and when.

The Gen Z approach to marketing texts

Gen Z customers are used to receiving information on their phones throughout the day. They might interact with a brand through social media, websites, apps, email, and SMS, all within the same customer journey.

When marketing to Gen Z, SMS messages tend to work best when they feel natural, direct, and connected to the customer's experience. Promotional texts can be particularly effective when there's a clear reason to act, whether that's a product launch, limited-time offer, exclusive access, or a product the customer has already shown interest in.

How Millennials approach marketing texts

Millennials are also comfortable with SMS as a marketing channel, particularly when messages provide practical value, like discounts, loyalty benefits, product recommendations, order updates, and reminders,

For marketing to Millennials, consistency and usefulness are key. Customers who have already purchased from a brand may appreciate messages that make their next interaction easier or more rewarding.

What Gen Z wants from SMS marketing

Keep the message relevant 

Relevance should sit at the center of personalized SMS marketing. Instead of sending every subscriber the same promotion, consider factors such as previous purchases, browsing behavior, product preferences, and engagement.

Make the value clear 

Gen Z customers are exposed to a constant stream of digital content, so the reason to open or act on a text should be easy to understand. Whether the message promotes early access, a new product, a limited-time offer, or a useful reminder, the benefit should be apparent without unnecessary wording. 

Use a conversational brand voice 

Brands can create stronger connections by writing in a way that sounds natural and matches the personality customers already experience across other channels. Forced slang or excessive emojis can quickly feel inauthentic. A tone that genuinely reflects the brand will work better.

What Millennials want from SMS marketing

Focus on practical value 

Millennials often respond well to messages that make shopping easier or offer a clear financial or practical benefit. A personalized product suggestion, loyalty reward, relevant discount, or useful reminder can give them a good reason to engage.

SMS retention marketing can also improve retention by supporting the broader customer journey and helping brands stay connected after the first purchase, rather than relying solely on acquisition campaigns. 

Respect their attention 

Sending messages too frequently can reduce engagement and increase unsubscribes. A better approach is to consider each customer's relationship with the brand. Someone who regularly engages with SMS will likely tolerate a different frequency than a subscriber who rarely opens or clicks messages.

Build consistency across channels 

SMS works best for Millennials when it fits naturally into the rest of the customer experience. A promotional text should complement email, website messaging, loyalty communications, and other touchpoints rather than simply repeating the same information.

How to build an SMS strategy for both generations 

Segment customers based on behavior, not age alone 

Age can help marketers form an initial hypothesis, but SMS marketing segmentation should be driven by stronger behavioral signals. Purchase frequency, average order value, product interests, and previous campaign activity can provide much more useful direction. 

For example, two customers of the same age may have completely different shopping habits. One may respond to early-access messages, while another may only engage when offered replenishment reminders. 

Personalize the customer journey 

Personalization can begin when a customer first subscribes, and continues throughout their relationship with the brand. Growth Gurus has helped e-commerce brands grow by 367% through personalized channel strategies, customer insights, and advanced segmentation.

Match the message to the customer lifecycle 

A first-time subscriber shouldn't receive the same message as a loyal customer. Someone who has just purchased may benefit from helpful post-purchase information, while a long-term customer may be more receptive to an early product announcement, exclusive offer, or loyalty reward.

Thinking about the customer's lifecycle stage helps brands make SMS communication feel intentional, rather than promotional.

SMS marketing tactics that work across generations 

Use targeted promotions 

Targeted SMS marketing lets brands match offers to customer interests and behavior. Instead of promoting every product to the entire database, brands can create smaller audiences around product categories, purchase history, engagement levels, or customer lifecycle stages.

Connect SMS with email marketing 

SMS and email play different roles within the same customer journey. Email provides space for detailed storytelling, education, product information, and richer content, while SMS delivers timely reminders, concise offers, and important updates.

Growth Gurus has used coordinated email and SMS strategies to achieve as much as a 38% increase in flow revenue for e-commerce brands within 90 days, showing how well-planned automated journeys can boost retention revenue.

Test timing, frequency, and content 

There's no universal sending schedule that works for every audience. Brands should test different send times, message formats, offers, and frequencies while monitoring engagement, conversions, and unsubscribe rates. 

Testing can also show whether assumptions about generational preferences actually apply to your particular customer base.
