Engage your audience instantly with SMS campaigns

What are SMS campaigns?

SMS campaigns, also known as SMS marketing campaigns, allow businesses to send targeted text messages to subscribers, delivering promotions, updates, and alerts directly to their mobile devices. With high open rates and near-instant engagement, SMS campaigns provide a direct and effective way to connect with customers.

SMS campaigns include one-time sends—for example, a single promotional text to a list or segment. Automated SMS flows, by contrast, are triggered by customer actions or timing—for example, a welcome text when someone signs up, or a series of follow-up messages post-purchase.

Why do SMS marketing campaigns matter for marketers?

SMS marketing campaigns stand out because they’re fast, direct, and incredibly effective. People almost always have their phones on them—making SMS the most immediate channel in a marketer’s toolkit.

For B2C brands in high-touch industries like retail, hospitality, and wellness, this means you can reach customers at exactly the right moment with promotions, reminders, or updates they’ll actually see. Whether it’s a flash sale, appointment nudge, or limited-time offer, SMS puts your message front and centre.

Beyond speed, SMS campaigns drive real business results. Studies show SMS can outperform other channels when it comes to engagement, click rates, and even revenue per recipient. Personalised texts sent to the right segment can convert at high rates, while timely reminders can reduce missed appointments and recover abandoned carts.

For marketers looking to improve ROI, add urgency to their messaging, or round out an omnichannel strategy, SMS marketing campaigns offer a proven, scalable way to engage customers in the moments that matter.

Why choose Klaviyo for your SMS campaigns?

1. Omnichannel reach with real-time engagement

Klaviyo helps you reach customers instantly across SMS, email, and mobile push—all from one unified platform—so your campaigns stay timely, relevant, and connected at every stage of the customer journey. Rather than managing channels separately, Klaviyo lets you orchestrate messaging across touchpoints, ensuring customers get the right message on the right channel at the right time.

Here are two ways that Klaviyo powers omnichannel campaigns:

2. Real-time reporting that drives smarter decisions

With Klaviyo’s built-in reporting tools, you don’t have to guess what’s working.
