For businesses, staying connected with your audience isn’t just a nice-to-have—it’s a must. And while email campaigns and social ads are great, there’s something about the immediacy of a good old-fashioned text that gets the job done. That’s where SMS marketing comes in.
Enter Klaviyo, a platform that’s making waves for helping businesses send smarter, more impactful texts. But is it worth the hype? Let’s break it down and find out why Klaviyo might just be the best SMS marketing service of 2025.
All About Klaviyo
First things first: Klaviyo isn’t just some new kid on the marketing block. Founded in 2012 by Andrew Bialecki and Ed Hallen, this Boston-based powerhouse is all about making life easier (and more profitable) for e-commerce brands. With over 157,000 companies in its corner, Klaviyo has helped its users rake in a jaw-dropping $100 billion in revenue.
Fun fact: The name Klaviyo (pronounced clay-vee-oh) is inspired by clavija, the Spanish word for mountaineering pins. Like those trusty tools climbers use, Klaviyo is here to support businesses on their climb to the top—and catch them if things get rocky. It’s precisely why it’s one of the top marketing automation tools available.
Oh, and SMS? It’s a big deal here. Over 19,000 brands already use Klaviyo’s unified platform to send texts that not only get read but actually drive sales.
Why SMS Marketing Is Still a Big Deal
Let’s cut to the chase—does SMS marketing still work? Short answer: yes. Long answer: it’s more powerful than ever. In a world overflowing with social media notifications, email promotions, and algorithm-controlled feeds, SMS remains refreshingly direct, personal, and immediate. No spam folders. No engagement throttling. Just a message delivered straight to your audience’s phone, where they’re most likely to see (and act on) it.
And the numbers don’t lie—74% of consumers subscribe to texts from multiple brands, and 65% have made an earlier-than-planned purchase because of a well-timed message. That’s not just engagement—it’s direct revenue impact. Unlike email, where inboxes are cluttered and easy to ignore, 90% of texts are read within three minutes, making SMS the ultimate channel for time-sensitive offers, reminders, and transactional updates.
But here’s the thing—SMS works best when it’s part of a bigger strategy. Many SMS-only tools focus solely on orchestrating texts, sending messages at every touchpoint. That’s fine in the short term, but a smarter approach considers the entire customer journey.
Klaviyo, for example, doesn’t just send texts—it helps brands balance email, SMS, and other channels to optimize engagement. Not every customer action requires a text message. A site browser with low intent might receive an email first, while a cart abandoner with high intent could get an SMS for urgency. This strategic approach prevents over-messaging and ensures brands are reaching customers in the right way, at the right time.
SMS: A Revenue Powerhouse in the Making
Here’s what’s even more exciting—SMS isn’t just a nice-to-have; it’s outperforming email in revenue per recipient (RPR) across B2C and e-commerce industries. Brands using Klaviyo’s unified SMS and email platform have already seen a 19% increase in gross merchandise value (GMV) growth. As SMS marketing strategies evolve and integrate more deeply with email best practices, its revenue potential is only growing.
That said, SMS is personal, and with that comes responsibility. Text subscribers are quicker to unsubscribe than email recipients, meaning every message needs to add value—whether it’s a time-sensitive deal, a critical update, or a personalized offer that actually matters. Get it right, and SMS becomes a high-impact, high-ROI channel that keeps customers engaged and businesses growing.
Klaviyo’s Secret Sauce: Smarter SMS
So, what makes Klaviyo’s SMS platform stand out? Two words: data smarts.
Imagine you’re running an online store. Klaviyo doesn’t just let you send generic texts—it taps into a treasure trove of data to create personalized, high-impact messages. With over 350 integrations across your tech stack, Klaviyo connects seamlessly with tools like Shopify, WooCommerce, and Salesforce to gather customer insights. This means every text, whether it’s a shipping update, loyalty reminder, or subscription renewal, feels timely and relevant.
But Klaviyo’s magic doesn’t stop at sending texts. It’s all about creating a unified, multichannel marketing strategy. Want to follow up a cart abandonment email with a gentle text nudge? Easy. Need to trigger a promo code after someone clicks on an email? Done. The platform’s multichannel flows let you craft cohesive campaigns across SMS, email, and even push notifications.
And let’s talk performance. Klaviyo’s SMS platform includes a powerful last-touch attribution feature that helps you track exactly which message—be it a text, email, or push alert—sealed the deal. Add in the SMS performance dashboard, and you’ve got real-time insights to optimize your campaigns on the fly.
If experimenting is your thing, Klaviyo has you covered with A/B testing tools and AI-driven suggestions. These features help you refine your strategy and even automate tasks like generating campaign ideas or crafting quick customer replies. It’s smarter marketing, streamlined for success.
