SMS Marketing Tool Comparison

FAQs

What is SMS marketing and why should e-commerce use it?

SMS marketing sends promotional and transactional text messages to opted-in subscribers. E-commerce benefits from 98% open rates (versus 20% for email), instant delivery, and high engagement. Text messages excel at time-sensitive communications like flash sales, shipping updates, and cart reminders. Adding SMS typically increases revenue 20-30%.

How much does SMS marketing cost for e-commerce?

SMS costs vary by platform and volume. Typical rates range from $0.007 to $0.02 per message in the US. Most platforms charge monthly fees plus per-message costs. Unified platforms like Omnisend include SMS in higher-tier plans. Budget approximately $50-200/month for small to medium stores depending on subscriber count and message frequency.

What are TCPA requirements for SMS marketing?

TCPA (Telephone Consumer Protection Act) requires explicit written consent before sending marketing texts. You need clear opt-in with disclosure of message frequency and content type. Include opt-out instructions in messages. Honor unsubscribe requests immediately. Non-compliance risks fines of $500-$1,500 per message. Good SMS platforms handle compliance automatically.

Should I use SMS and email together or separately?

Using SMS and email together delivers better results than either alone. Email handles detailed content and relationship building. SMS drives immediate action for urgent messages. Unified platforms like Omnisend coordinate both channels in single workflows, preventing over-messaging while maximizing touchpoints. Combined revenue attribution shows true campaign impact.

What SMS messages should e-commerce stores send?

Essential e-commerce SMS includes: abandoned cart reminders, order confirmations, shipping notifications, delivery updates, and back-in-stock alerts. Promotional messages include flash sales, exclusive offers, and limited-time discounts. Keep promotional frequency lower than email. Transactional messages can send without prior consent as they’re expected communications.

How do I grow my SMS subscriber list?

Effective SMS list building strategies include: popup opt-ins offering discounts, checkout opt-in checkboxes, keyword campaigns where customers text to subscribe, and contests or giveaways requiring SMS signup. Always provide clear value proposition for subscribing. Many stores see 10-20% conversion from website visitors to SMS subscribers with good offers.

What is the best time to send SMS marketing messages?

Generally, mid-morning (10-11am) and early evening (6-8pm) perform well for promotional SMS. Avoid very early morning and late night. Respect quiet hours typically 9pm-9am in recipient time zones. Cart abandonment texts work best 1-2 hours after abandonment. Test timing with your specific audience as optimal windows vary by demographic.

How many SMS messages should I send per month?

Most e-commerce brands send 4-8 promotional SMS per month. More than one per week risks subscriber fatigue. Transactional messages (order confirmations, shipping) don’t count toward this limit. Monitor unsubscribe rates closely. If opt-outs spike, reduce frequency. Quality and relevance matter more than volume for SMS.

What is MMS and should I use it?

MMS (Multimedia Messaging Service) includes images, GIFs, or video in text messages. Product images in MMS can increase click-through rates significantly. However, MMS costs more per message and not all carriers support it. Use MMS strategically for product launches and high-value promotions. Standard SMS handles most e-commerce messaging effectively.

How do I integrate SMS with my e-commerce platform?

Most SMS platforms offer native integrations with Shopify, WooCommerce, BigCommerce, and other platforms. Install the integration app, connect your store, and sync customer data. E-commerce-focused platforms like Omnisend and Klaviyo provide deeper integration with automatic event tracking, product data sync, and revenue attribution.

What metrics should I track for SMS marketing?

Key SMS metrics include: delivery rate (should exceed 95%), click-through rate (3-10% typical), conversion rate, revenue per message, unsubscribe rate (keep under 2%), and ROI. Compare performance across campaigns and automations. Track subscriber list growth over time. Good platforms provide revenue attribution showing exactly which messages drive sales.

Why is Omnisend recommended for e-commerce SMS?

Omnisend provides the best combination of SMS and email marketing for e-commerce. The unified platform eliminates juggling multiple tools while coordinating messages across channels. Volume-based SMS pricing keeps costs reasonable. Pre-built e-commerce automations include SMS touchpoints. Over 150,000 brands trust Omnisend for omnichannel marketing with proven ROI.

What is the best SMS marketing tool for e-commerce?

Omnisend is the best SMS tool for most e-commerce stores because it combines SMS and email automations in one platform. Klaviyo is stronger for data-heavy segmentation, and Postscript is a strong Shopify-only option. Pick the one that matches your store platform and whether you also want email in the same tool.

How much does SMS cost per message?

Costs vary by tool and volume. Omnisend charges $0.007 to $0.009 per US SMS on its Pro plan, and Twilio charges $0.0083 per US segment plus carrier fees of roughly $0.0035 to $0.005. Most platforms bill a monthly plan plus per-message credits, so estimate your monthly send volume first.

Final Thoughts

SMS marketing adds a high-converting channel that cuts through inbox clutter to reach customers instantly.
