SMS marketing is a high-impact channel—if done right. While text messages have exceptionally high open rates, it only takes a few missteps for subscribers to opt out. Here are five proven strategies to keep your SMS campaigns relevant, engaging, and effective, all while respecting your audience’s preferences.

1. Time Your SMS Messages Effectively

Timing can make or break an sms campaign. Sending texts at peak hours (such as early mornings or late evenings) might disrupt subscribers and lead to higher unsubscribe rates. On the flip side, dropping a promotion mid-afternoon—when people typically check their phones—can result in better engagement and click-throughs.

  • Consider Time Zones: If you’re dealing with a geographically dispersed audience, adapt your campaign schedule based on local time zones.
  • Mind Industry Norms: Restaurants, for example, see success with lunchtime or dinnertime texts, while eCommerce brands might perform well in the early evening.
  • Use Drip Scheduling: Rather than blasting your entire list at once, you can stagger sends to test optimal send times. For more insight on scheduling messages effectively, see our post on When is the Best Time to Send SMS Marketing Messages?

Pro Tip: A/B test different send times for each campaign. You’ll identify the sweet spot for your audience without spamming them outside preferred hours.

2. Provide Easy Opt-Out Options

Just as your subscribers opted in, they must be able to opt out whenever they wish. Offering a clear way to unsubscribe (e.g., “Reply STOP to end messages”) is both a legal requirement in many regions and a sign of respect for your subscribers’ time and boundaries.

  • Legality and Compliance: Laws like the Telephone Consumer Protection Act (TCPA) in the U.S. require a simple unsubscribe method in each text message.
  • Automatic Workflow: Many SMS marketing platforms, such as Dripcel, can auto-log new and canceled subscriptions. This keeps your lists clean and accurate.

By being transparent and straightforward, you reduce frustration and build trust. For general guidance on SMS compliance, check out U.S. SMS Compliance Guide.

3. Maintain Consistent Text Volume

Consistency is crucial when it comes to sms marketing campaigns. Bombarding subscribers daily is a surefire way to earn unsubscribes, but going silent for months can make your audience forget why they signed up in the first place.

  • Avoid ‘Message Fatigue: Too many promotional texts can irritate customers, causing them to unsubscribe or ignore future messages.
  • Stay Memorable: A consistent schedule—whether weekly, bi-weekly, or monthly—ensures your brand remains recognizable and relevant.
  • Segment Your Lists: Different segments may tolerate different frequencies. VIP customers might enjoy more frequent communication, while occasional shoppers prefer fewer pings.

Pro Tip: Use a/b testing to find the perfect cadence for each audience segment. Track click-through and conversion rates to see how often subscribers can be contacted before engagement drops.

4. Ensure Clear Calls to Action

A brilliant text message without a clear call-to-action (CTA) is a missed opportunity. Make it unmistakable what you want recipients to do next—whether that’s redeeming a discount code, visiting your website, or replying with feedback.

  • Keep It Short & Direct: SMS is limited in characters, so clarity is key. Instead of multiple asks, focus on one primary action (e.g., “Shop now,” “Learn more,” “Reply YES,” etc.).
  • Leverage Urgency: Limited-time offers, low-stock notifications, or seasonal promos can motivate faster responses.
  • Measure Results: Track CTA clicks, reply rates, and conversions to refine future campaigns.

Example: “Only 12 hours left to claim 20% off! Click [Shortened Link] to shop now.”

5. Communicate Directly and Personally

SMS is a deeply personal channel. Make sure your messages speak directly to your subscribers’ needs, reflect genuine empathy, and offer real value. Generic or overly formal texts often get dismissed.

  • Use Personalization: Address subscribers by name or reference their past purchases. Personalized texts consistently show higher click-through and conversion rates.
  • Match the Tone to the Brand: If your brand voice is fun and casual, keep your SMS copy short, lively, and on-brand. If you cater to a more formal audience, maintain a professional tone.
  • Ask for Feedback: Two-way SMS can transform marketing into a conversation. Encourage replies (“Need help?” “Got a question?”). When you show you’re listening, subscribers feel valued.

Measuring Success: Key Performance Indicators

Optimizing an sms marketing strategy involves tracking the right metrics:

  • Delivery Rate: Ensures your messages actually reach recipients.
  • Click-Through Rate (CTR): Shows how many recipients clicked your link.
  • Conversion Rate: Measures completed purchases, sign-ups, or other desired actions.
  • Unsubscribe Rate: Gauges how many people opt out after each campaign. A sudden spike may signal over-frequency or irrelevant content.

Pair these indicators with a/b testing on send times, segment targeting, and copy style to continually refine your sms marketing approach.
