SMS marketing isn't just about sending text messages—it's about building relationships, driving action, and respecting your audience. With 98% open rates (CTIA Mobile Messaging Report, 2024) and the average person checking their phone 96 times per day, SMS is the most direct channel to reach customers. But with great power comes great responsibility.
Why SMS Marketing Best Practices Matter
Before diving into tactics, understand this: one bad SMS campaign can destroy years of customer goodwill. Text messages are intimate. They appear on the same screen as messages from friends and family. Abuse this privilege, and you'll see opt-out rates spike and brand reputation plummet.
The businesses winning at SMS marketing follow proven best practices that balance aggressive growth with customer respect. Let's break down the 15 strategies that separate the pros from the spammers.
1. Get Explicit Written Consent (It's the Law)
The TCPA (Telephone Consumer Protection Act) requires explicit written consent before sending marketing texts. This isn't optional—violations cost $500 to $1,500 per text.
How to get proper consent:
- Use clear opt-in language: "I agree to receive SMS marketing messages from [Your Brand]"
- Include frequency expectations: "Msg frequency varies. Msg & data rates may apply."
- Provide opt-out instructions: "Text STOP to unsubscribe"
- Keep records of all opt-ins with timestamps
What NOT to do:
- Pre-checked boxes
- Implied consent from email subscriptions
- Purchasing phone lists
2. Timing Is Everything: When to Send SMS
Sending a promotional text at 3 AM is a fast track to opt-outs. Respect your subscribers' time zones and daily routines.
Best times to send marketing texts:
- Tuesday-Thursday: 10 AM - 1 PM (Highest engagement)
- Tuesday-Thursday: 6 PM - 9 PM (Second best)
- Avoid: Before 9 AM, after 9 PM, Sundays, major holidays
Industry-specific timing:
- Restaurants: 10-11 AM (lunch planning), 3-4 PM (dinner planning) - Learn more about restaurant SMS marketing
- E-commerce: Tuesday-Thursday afternoons - See e-commerce SMS strategies
- Real Estate: Mid-morning for property updates - Explore real estate SMS solutions
- Healthcare: Mid-day for appointment reminders - Discover healthcare text messaging
- Retail: Thursdays (pre-weekend shopping) - View retail SMS marketing
3. Personalize Beyond "Hi {FirstName}"
Generic mass texts get ignored. Personalization drives 6x higher transaction rates (Epsilon Personalization Report, 2024).
Advanced personalization tactics:
- Reference past purchases: "Your favorite [Product] is back in stock!"
- Location-based offers: "Stop by our [City] location today for 20% off"
- Behavior triggers: "You left items in your cart. Complete your order now: [link]"
- Purchase anniversary: "It's been a year since you bought [Product]. Ready for a replacement?"
Data to collect and use:
- Purchase history
- Browsing behavior
- Location
- Preferences
- Birthday/anniversary dates
4. Keep It Short: 160 Characters or Less
SMS has a hard limit of 160 characters before it splits into multiple messages. Longer messages cost more and dilute your point.
Formula for concise SMS:
- Hook (20-30 chars): Grab attention
- Offer (50-80 chars): State the value
- CTA (20-30 chars): Tell them what to do
- Opt-out (10-20 chars): Reply STOP to end
Example:
"FLASH SALE: 50% off all sneakers for the next 3 hours! Shop now: [link]. Reply STOP to end."
5. Include a Clear Call-to-Action
Every text needs a single, crystal-clear action. Multiple CTAs confuse recipients and tank conversion rates.
Strong CTAs:
- "Shop now: [link]"
- "Reply YES to claim your discount"
- "Show this text at checkout"
- "Book your appointment: [link]"
Weak CTAs:
- "Check out our website"
- "Learn more"
- "Visit us soon"
6. Use URL Shorteners with Tracking
Long URLs eat character counts and look unprofessional. Shortened URLs also enable click tracking for ROI analysis.
Best practices for SMS links:
- Use branded short domains (go.yourbrand.com)
- Include UTM parameters for analytics
- Ensure mobile-optimized landing pages
- Test links before sending
Example:
❌ https://www.yourstore.com/products/winter-sale-2024-limited-time-offer
✅ go.store.com/winter50
7. Segment Your Audience for Relevance
Sending the same message to everyone is lazy and ineffective. Segmentation increases relevance and engagement.
Critical segments to create:
- New subscribers: Welcome series, brand education
- Active customers: Exclusive offers, loyalty rewards
- Dormant customers: Re-engagement campaigns
- High-value customers: VIP early access
- Geographic location: Local events, store-specific offers
- Product interests: Category-based promotions
Results from segmentation (Campaign Monitor SMS Study, 2024):
- 50% higher open rates
- 3x higher conversion rates
- 25% lower opt-out rates
8. Test Everything Before Sending
One typo, one broken link, one wrong merge field = thousands of confused customers and destroyed credibility.
Pre-send checklist:
- ✅ Test on actual mobile devices (iPhone & Android)
- ✅ Verify all links work and go to mobile-friendly pages
- ✅ Check personalization tokens populate correctly
- ✅ Confirm opt-out instructions are present
- ✅ Review message length (under 160 characters)
- ✅ Send test to 3-5 internal recipients
9. Frequency Matters: Don't Spam
The #1 reason people opt out? Too many messages. Find the sweet spot between staying top-of-mind and being annoying.
Recommended frequency:
- Promotional texts: 1-4 per month
- Transactional texts: As needed (order updates, appointments)
- Time-sensitive offers: Max 1 per week
- Abandoned cart: 1-3 messages over 72 hours
Set expectations upfront:
"By subscribing, you'll receive 2-4 promotional texts per month. Reply STOP to opt-out anytime."
10. Comply with TCPA, CAN-SPAM, and GDPR
Ignorance of regulations isn't a defense. Compliance protects both your customers and your business.
TCPA requirements:
- Prior express written consent
- Clear identification of sender
- Opt-out mechanism in every message
- Honor opt-outs within 10 days
Best practices:
- Include company name in first message
- Don't share/sell phone numbers
- Maintain do-not-contact lists
- Regular compliance audits
11. Optimize Landing Pages for Mobile
58% of consumers click SMS links. If your landing page isn't mobile-optimized, you're wasting money.
Mobile landing page essentials:
- Load in under 3 seconds
- Large, thumb-friendly buttons
- Minimal form fields
- One clear conversion goal
- No intrusive popups
Test on:
- iPhone (Safari)
- Android (Chrome)
- Slow 3G connections
12. Leverage Automation (But Stay Human)
Automation scales your SMS marketing without sacrificing personalization. Set up triggers based on customer actions.
Automated campaigns that work:
- Welcome series: "Thanks for subscribing! Here's 15% off your first order: [link]"
- Cart abandonment: "You left $X in your cart. Complete checkout: [link]"
- Post-purchase: "How was your order? Leave a review: [link]"
- Re-engagement: "We miss you! Come back for 20% off: [link]"
- Birthday/Anniversary: "Happy birthday! Here's a special gift: [link]"
13. A/B Test Your Messages
Small changes in copy, timing, or offers can double your results. Test systematically.
What to test:
- Send time (morning vs. evening)
- Message length (short vs. detailed)
- Offer type (percentage vs. dollar amount)
- CTA wording ("Shop now" vs. "Claim offer")
- Personalization level (name only vs. purchase history)
- Emojis (with vs. without)
Testing methodology:
- Test one variable at a time
- Use minimum 1,000 recipients per variant
- Let test run for at least 24 hours
- Track conversions, not just clicks
- Implement winner as new baseline
14. Track and Measure ROI
You can't optimize what you don't measure. Track these KPIs for every campaign.
Essential SMS metrics:
- Delivery rate: >95% is healthy
- Open rate: SMS averages 98%
- Click-through rate: 20-45% is excellent
- Conversion rate: Varies by industry (5-15% typical)
- Opt-out rate: <1% per campaign is good
- Revenue per message: Track directly attributed sales
Tools to use:
- SMS platform analytics
- Google Analytics with UTM tracking
- CRM integration for sales attribution
- A/B testing platforms
15. Respect Opt-Outs Immediately
When someone texts STOP, honor it instantly. Not only is this the law, it's basic respect.
Opt-out best practices:
- Process STOP, UNSUBSCRIBE, CANCEL, END, and QUIT
- Send confirmation: "You've been unsubscribed. No more messages."
- Remove from lists within minutes, not days
- Don't require additional steps or confirmations
- Never re-add without new explicit consent
