E-commerce brands on Shopify wanting email and SMS in a single platform
- Pro: Unified email + SMS segmentation, trigger SMS based on email behavior and vice versa
- Pro: Deep Shopify integration with pre-built abandoned cart, welcome, and post-purchase SMS flows
- Pro: Since 13 July 2026, mobile plans are dollar commits ($15 or $25 examples) with per-message rates by channel and region
- Con: Email and SMS are billed separately from the free 250-profile email plan
- Con: Unused mobile dollars do not roll over
Since February 2025, billing is based on total active profiles (not just emailed contacts), which effectively raised prices for most users.
Watch out
Since Feb 2025, you pay for ALL active profiles, not just contacts you email. Imported but unengaged contacts still count toward billing
Larger DTC brands wanting two-way conversational SMS with AI-powered optimization
- Pro: Best-in-class subscriber growth tools, pop-ups, email-to-SMS, and two-tap opt-in capture 2-3x more subscribers
- Pro: Conversational two-way messaging lets customers reply and get automated responses
- Pro: AI-powered send time and content optimization improves click-through rates by 15-25%
- Con: Enterprise pricing starts around $500/month, not accessible for small businesses
- Con: Annual contracts required with minimum spend commitments
The 'Text Only' tier likely offers a competitive entry point for SMS, but the value of 'Text and Email' and 'Text, Email, and Push' depends heavily on the cost-effectiveness of their integrated solutions compared to standalone providers.
Watch out
Overage fees for exceeding message limits
Small businesses wanting straightforward SMS marketing without complexity
- Pro: $29/month for 500 credits with rollover, unused credits don't expire

- Con: Less sophisticated automation, no AI optimization or predictive send times
- Con: Basic e-commerce integrations, Shopify connection less deep than Klaviyo
SimpleTexting's pricing is fair for small to medium businesses, with the 500 Credits tier at $29 offering good value for basic needs.
Engineering teams that need full programmatic SMS APIs for product notifications, two-factor auth, and custom marketing.
- Pro: Industry-leading API
- Pro: Pay-per-message
- Pro: Wide global coverage
- Con: API-only, no marketing UI
- Con: Per-message pricing
Twilio is the industry standard for communication APIs, but the pay-as-you-go pricing adds up fast at scale.
Watch out
SendGrid email is a separate product with its own pricing, not included in Twilio communication credits.

What is SMS Marketing?
SMS marketing platforms send text messages to customers for promotions, updates, and engagement. They handle subscriber management, message composition, segmentation, automation, compliance (TCPA, GDPR), and analytics. Modern platforms go beyond blast messages to include two-way conversations, MMS, and integration with broader marketing automation.
Why SMS Marketing Matters
SMS cuts through the noise that email can't. With 98% open rates and 90% of messages read within 3 minutes, it's the most direct channel available. For flash sales, appointment reminders, shipping updates, and cart recovery, SMS significantly outperforms email. But it requires respect, abuse the channel and customers opt out permanently.
Key Features to Look For
Compliance Management (Essential)
Built-in TCPA compliance, opt-in/opt-out handling, quiet hours
Segmentation (Essential)
Target messages based on behavior, purchase history, preferences
Automation (Essential)
Triggered messages for cart abandonment, welcome series, etc.
Two-Way Messaging (Important)
Conversational SMS where customers can reply
MMS Support (Important)
Send images and rich media, not just text
E-commerce Integration (Important)
Connect with Shopify, Klaviyo, etc. for triggered campaigns
Analytics (Important)
Track deliverability, clicks, conversions, and revenue attribution
A/B Testing (Nice to have)
Test message variations to optimize performance
Key Factors to Consider
Message volume: pricing usually scales with messages sent
E-commerce integration depth matters if SMS is tied to shopping behavior
Compliance features: TCPA violations are expensive, ensure the platform handles this
International sending: rates and capabilities vary by country
Conversational vs. broadcast: do you need two-way messaging?
Evaluation Checklist
Send test messages to 5 different phone numbers across carriers (AT&T, Verizon, T-Mobile), verify delivery speed (should be under 10 seconds) and that messages aren't filtered as spam
Set up an abandoned cart automation and trigger it with a test order, verify the timing, message content, and product link all work correctly on mobile
Test opt-in and opt-out flows end-to-end, text STOP to your number and verify immediate removal. Text START and verify re-subscription. TCPA compliance depends on this working perfectly
Check quiet hours enforcement, schedule a message at 10pm and verify the platform holds it until the next morning (typically 9am in recipient's timezone)
Calculate cost-per-message at your expected volume, Klaviyo now shows dollar rates by channel and region instead of credits; MMS still costs more than SMS

Mistakes to Avoid
- ×
Sending more than 4-6 messages per month, SMS tolerance is much lower than email. Industry data shows unsubscribe rates spike above 6 messages/month. Each message must deliver clear value, exclusive offers, time-sensitive restocks, or personalized alerts
- ×
Skipping proper opt-in consent, TCPA violations carry penalties of $500-1,500 per non-compliant message. A class action against a brand sending 10,000 unconsented messages = $5M-15M exposure. Use double opt-in and maintain timestamp records of every consent
- ×
Ignoring quiet hours, Messages between 9pm-9am in the recipient's timezone violate TCPA and annoy customers. All three platforms enforce quiet hours, but verify they use recipient timezone, not your timezone
- ×
Treating SMS like email, SMS has 160-character limit for standard messages. Long messages split into multiple SMS (each costing separately). Write concise, action-oriented copy with one clear CTA. MMS allows images but costs 2-3x more
- ×
No clear opt-out in every message, 'Reply STOP to opt out' is legally required in every marketing SMS. Platforms handle this automatically, but verify it works on test messages. Slow opt-out processing leads to complaints and carrier filtering
Expert Tips
- →
Use SMS for time-sensitive, high-value messages only, Flash sales (2-hour window), back-in-stock alerts, and abandoned cart recovery (within 1 hour) are the highest-ROI SMS use cases. Average SMS campaign revenue: $0.25-0.50 per message sent
- →
Combine SMS + email strategically, Send email first with full details, then follow up with SMS for urgency: 'Sale ends in 2 hours. Shop now: [link].' Klaviyo's unified platform makes this easy to orchestrate
- →
Segment by purchase behavior, not just demographics, Send restock reminders to customers who bought consumable products 30-60 days ago. This personalization drives 3-5x higher conversion than blast campaigns
- →
Calculate true cost per conversion, Track revenue per SMS sent, not just clicks. If you spend $0.012/message with 5% conversion and $50 AOV, each sale costs $0.24 in SMS, exceptional ROI. SimpleTexting and Klaviyo both offer revenue attribution
- →
Register your number for 10DLC immediately, Since 2023, US carriers require A2P (application-to-person) registration for business SMS. Unregistered numbers face throttling and higher filtering. Registration takes 2-4 weeks, start before your first campaign
Red Flags to Watch For
-
No built-in TCPA compliance, platforms without automatic quiet hours, opt-out handling, and consent tracking expose you to $500-1,500 fines per non-compliant message
-
Shared short code instead of dedicated number, messages from shared codes have higher spam filter rates and less brand recognition
-
No carrier registration (10DLC/A2P), unregistered numbers face throttling (1 message/second) and higher filtering rates since 2023 carrier regulations
-
Message costs significantly above $0.03/SMS, some platforms markup carrier costs by 2-3x. Compare raw per-message pricing across platforms
The Bottom Line
Klaviyo (Mobile Messaging dollar commits from $15/month on the official billing page) is the clear choice for e-commerce brands wanting unified email + SMS with deep Shopify integration. Attentive remains a sales-quoted enterprise pick for larger DTC brands. SimpleTexting and Postscript paid dollars were not re-fetched this pass. SMS still has almost no tolerance for spam, respect the channel or lose subscribers permanently.
Frequently Asked Questions
What's a good SMS opt-in rate?
2-5% of website visitors or email subscribers is typical. Incentives (discounts, exclusive access) can push this higher. Quality matters more than quantity, engaged subscribers drive revenue; disengaged ones will opt out.
How much does SMS marketing cost per message?
Typically $0.01-$0.03 per SMS in the US, more for MMS ($0.02-$0.05). International rates vary significantly. Plus platform fees. Budget $50-500/month for a program of 5,000-50,000 messages.
How do I stay TCPA compliant?
Get explicit opt-in consent (not implied), honor opt-outs immediately, respect quiet hours (typically 8am-9pm), identify yourself in messages, and maintain consent records. Good platforms handle most of this automatically.
