What is SMS Marketing?
You might be wondering—with WhatsApp, Facebook Messenger, and email, does SMS marketing even matter anymore? The answer is a resounding yes. While instant messaging apps require Wi-Fi or app downloads, text messages land directly in a person’s inbox, no internet needed. And consumers are loving it.
In fact, 74% of consumers subscribe to SMS from at least two to five brands, and 72% globally want weekly texts from brands—a clear sign that people are actively looking for text-based communication from businesses. But here’s where it gets even more interesting: 65% of consumers have made a purchase sooner than planned just because of a text message. That’s right—SMS isn’t just another marketing tool; it’s a direct line to faster sales.
And while many brands are using SMS, not all platforms do it well. Traditional SMS marketing services focus only on sending texts, but Klaviyo takes it a step further. Brands using Klaviyo for both email and SMS see a 19% increase in GMV (Gross Merchandise Value) growth rate—proof that Klaviyo isn’t just about sending messages, it’s about sending the right messages at the right time using customer data, automation, and AI-powered insights.
Why Klaviyo?
Most SMS marketing platforms operate in a vacuum—they help brands send texts, but they don’t consider the bigger picture. That’s where Klaviyo shines. Instead of treating SMS as a standalone channel, Klaviyo seamlessly integrates it with email and other marketing touchpoints, ensuring every message fits into a larger customer journey.
Let’s break it down.
- Traditional SMS platforms blast texts at every stage of the funnel.
- Klaviyo strategically determines when a text is the right move.
For example, say a customer casually browses your website but doesn’t add anything to their cart. Sending an SMS here? Overkill. Instead, Klaviyo might trigger an email first—keeping things low-pressure. But if that same customer abandons their cart with items inside? That’s a high-intent action. That’s when Klaviyo fires off an SMS with an exclusive discount, perfectly timed to nudge them toward a purchase.
This multi-channel approach helps brands avoid over-messaging low-intent customers while maximizing engagement from high-intent buyers. It’s not just about sending texts; it’s about sending smart texts.
Why SMS Crushes Other Channels
Still not convinced? Let’s talk numbers.
- Text messages are read within 3 minutes. Emails? They might sit in an inbox for hours (or worse, land in spam).
- SMS drives urgency. It’s personal, direct, and people check their phones constantly.
- SMS already outperforms email in revenue per recipient (RPR). Across e-commerce industries, brands are seeing higher earnings per text sent than per email.
That’s huge. Marketers leading the way in SMS today are already seeing returns that could surpass email over time. Why? Because SMS is immediate and intimate. People carry their phones everywhere and use them to connect with family and friends. That’s why brands have to be thoughtful with SMS marketing—spammy texts get unsubscribed from fast.
Klaviyo understands this balance better than anyone. It ensures brands use SMS only when it truly matters—whether for time-sensitive sales, shipping updates, or VIP-only deals. That way, instead of annoying customers, brands build real, lasting relationships.
Smarter SMS, Powered by Data
Klaviyo isn’t just about sending texts—it’s about sending the right texts at the right time using smarter SMS marketing powered by all your customer data. While other platforms treat SMS as just another marketing tool, Klaviyo weaves it into a brand’s entire marketing ecosystem, ensuring that every message feels personal, relevant, and action-driven.
How does it do that? With intelligence.
Klaviyo seamlessly integrates SMS with email, customer data, and AI-driven automation to create hyper-personalized customer journeys.

Whether it’s an exclusive promo, a shipping update, or a subscription reminder, Klaviyo ensures texts actually add value—not just noise.
But it’s not just about messaging smarter—it’s about messaging safely.
