SMS is no longer a “nice to have.”

For small and growing brands, it is one of the highest-performing owned channels in 2025.

Customers check their phones constantly. They read texts almost instantly. And unlike crowded inboxes or unpredictable algorithms, SMS puts your message right where people pay attention.

If you are new to SMS marketing or you have only dabbled with it, you are in the right place. This guide breaks down what SMS marketing is, why it performs so well for e-commerce, and how to start using it confidently with Privy.

Let’s walk through how to use it without complexity, pressure, or guesswork.

What Is SMS Marketing?

SMS marketing is the high-value practice of sending promotional, transactional, or service-related messages to your customers through text message. Think of it as the shortest path between your brand and your shopper.

Examples include:

• Flash sale announcements
• Abandoned cart reminders
• VIP early access
• Delivery updates
• Loyalty rewards
• One-to-one customer support text conversations

Because texts are read so quickly, SMS becomes a strong companion to email. Email tells the full story. SMS delivers the moment that needs immediate action.

With Privy, SMS sits inside the same ecosystem as your email, popups, automations, and onsite personalization. That means one login, one customer profile, and one place to see how your marketing works together.

Why SMS Marketing Works So Well

SMS performs the way marketers wish every channel performed. Here is why e-commerce brands rely on it.

• 98% open rates - Most text messages are read within minutes. Customers rarely ignore SMS notifications.
• 45% response rates - Compared to the average 6% response rate for email, SMS creates instant engagement.
• Mobile first behavior - Shoppers browse, compare, and buy on their phones. SMS meets customers where they already are.
• Low cost and high ROI - A small list can generate meaningful revenue because conversions are strong and messages are inexpensive.
• Fast, direct communication - Shipping update? VIP drop? Cart reminder? SMS gets that message in front of your customer without delay.

SMS is effective because it cuts through noise and arrives during the exact moment a shopper can take action.

SMS Marketing Use Cases for E-commerce

SMS fits naturally across the full customer journey. Here are the most common high-performing use cases:

Promotions and Flash Sales

Perfect for time-sensitive offers, sell-out alerts, or weekend drop announcements.

Abandoned Cart Reminders

Recover lost revenue with friendly nudges sent minutes after a cart is left behind.

Order Confirmations

Reduce support tickets by sending clear confirmation messages that customers trust.

Shipping Updates

Real-time tracking details build confidence and reduce “Where is my order?” emails.

Loyalty and VIP Rewards

Share exclusive access, early product drops, or points balance updates with your best customers.

Two-Way Support Conversations

Let customers ask questions and get quick answers from your team through conversational SMS. With Privy, these touchpoints come prebuilt as automated flows. You pick the trigger and timing. The system handles the rest.

How to Build an SMS Marketing Strategy

Starting an SMS program does not have to be complicated. You only need a few core steps to get going confidently.

Build Your List Legally

SMS requires explicit opt-in. That means customers must knowingly agree to receive text messages from you. Privy popups include compliant language by default and support double opt-in when needed.

Segment Your Audience

Not every subscriber needs the same message. Segment by purchase history, browsing behavior, location, or engagement level.

Personalize Your Messaging

Use first names. Reference past orders. Tailor offers to what customers have shown interest in. Personalization makes SMS feel helpful rather than intrusive.

Time It Right

Avoid sending messages too early or too late. Respect quiet hours and time zones. Privy automatically prevents sends during restricted windows.

Automate When Possible

Use workflows for cart abandonment, welcome messages, post-purchase thank yous, and replenishment reminders. Automation does the heavy lifting for you.

Best Practices for High-Performing SMS Campaigns

Here are simple guidelines to maximize your results:

• Keep messages short and clear. Aim for 160 characters.
• Include a direct CTA so customers know what action to take.
• Always include opt-out instructions. “Reply STOP to unsubscribe.”
• Test send times, offers, and copy to see what resonates.
• Avoid over-sending. SMS is powerful because it is personal. Respect the channel.

What Tools Do You Need for SMS Marketing?

A good SMS marketing platform should provide:

• List growth tools like popups, embedded forms, QR codes, and checkout collection
• Audience segmentation and personalization features
• Automated workflows and triggers for lifecycle messaging
• Two-way conversational support
• Analytics and tracking for message performance and revenue attribution
• Integrations with your e-commerce platform, CRM, help desk, and email tool

Privy brings all of this together inside one ecosystem so you never have to stitch tools together or manage data across multiple apps.

You can collect email and SMS from the same popup, use shared customer profiles, and run automated flows without technical setup or expensive complexity.
