Yes, Klaviyo integrates with SMS platforms to enable text message campaigns alongside email marketing.
Overview
Klaviyo is a customer data and marketing automation platform built for e-commerce and direct-to-consumer brands. SMS integration extends Klaviyo’s capabilities beyond email into text messaging, allowing you to reach customers on the channel where they’re most likely to engage. This integration enables you to build cohesive omnichannel campaigns that combine email, SMS, and other messaging channels from a single platform.
If you’re managing customer communications across multiple touchpoints, adding SMS to your Klaviyo workflows means fewer platform switches, more consistent messaging, and better customer data synchronization. The integration works through third-party SMS providers that connect directly to Klaviyo, making it possible to trigger text messages based on customer behavior, segment audiences, and track SMS performance alongside your email metrics.
How the Integration Works
- Third-party SMS provider connection: Klaviyo connects to SMS platforms via API integrations or pre-built connectors. You authorize the SMS provider within Klaviyo, which allows the two systems to communicate securely.
- Customer data synchronization: Phone numbers stored in Klaviyo segments and profiles automatically sync to your SMS provider, ensuring your contact lists stay current across both platforms.
- Triggered SMS campaigns: Build workflows in Klaviyo that send SMS messages based on customer actions—like a text confirmation after purchase, a reminder when an item is back in stock, or a win-back message to inactive customers.
- Unified audience segmentation: Segment customers by behavior, purchase history, or engagement level, then send targeted SMS campaigns to those specific groups without manual list management.
- Performance tracking: SMS delivery, open rates, click rates, and conversion data flow back into Klaviyo, giving you a complete view of campaign performance across email and SMS channels.
Key Features & Capabilities
- Automated SMS workflows: Trigger text messages based on customer actions—welcome messages for new subscribers, abandoned cart reminders, post-purchase follow-ups, and re-engagement campaigns.
- Scheduled SMS campaigns: Send one-time SMS blasts to your entire list or specific segments at a time that works for your audience, with full control over send windows and frequency capping.
- Personalized messaging: Use customer data from Klaviyo (first name, purchase history, loyalty tier) to personalize SMS content and increase relevance and response rates.
- Compliance and consent management: Manage SMS opt-in/opt-out preferences directly within Klaviyo, ensuring you stay compliant with TCPA and other SMS regulations.
- A/B testing: Test different SMS message variations to see which resonates with your audience, then automatically send the winning version to the remainder of your list.
- Cross-channel attribution: See which SMS messages drive conversions, and understand how SMS interacts with email and other channels in your customer journey.
Setup Difficulty
Medium (15–30 minutes, some configuration required)
Setting up SMS integration in Klaviyo requires you to have an active account with a compatible SMS provider, then authorize that provider within Klaviyo. You’ll need to verify your phone number, configure sender ID settings, and map phone number fields from your customer database. No coding is required, but you should be comfortable navigating API keys, webhooks, and basic integration settings. If you’re new to SMS marketing, you may also want to review compliance requirements (like TCPA consent rules) before launching campaigns.
Alternatives
If the native Klaviyo SMS integration doesn’t meet your needs, consider these options:
- Zapier or Make (formerly Integromat): Use these no-code automation platforms to connect Klaviyo to SMS providers like Twilio, Telnyx, or Bandwidth. This approach offers flexibility but may have higher per-action costs and less native feature parity than a direct integration.
- Direct SMS provider API: If you have developer resources, build a custom integration between Klaviyo and your SMS provider using their APIs. This gives you full control but requires ongoing maintenance.
- Switch to an all-in-one platform: Platforms like Klaviyo’s SMS-enabled competitors (e.g., Omnisend, Attentive, or Postscript) offer native SMS alongside email, eliminating the need for a separate integration.
Frequently Asked Questions
Does Klaviyo SMS integration work with all SMS providers?
Klaviyo integrates with major SMS providers, but not all. The most common integrations are with platforms like Twilio, Telnyx, and carrier-based SMS services. Before committing to an SMS provider, verify that it’s listed as a supported integration in Klaviyo’s app marketplace or contact Klaviyo support to confirm compatibility.
Can I send SMS to customers who haven’t opted in?
No. SMS marketing is heavily regulated under laws like the TCPA (in the US) and GDPR (in Europe). Klaviyo enforces opt-in requirements, meaning you can only send SMS to customers who have explicitly consented to receive text messages. You must collect and maintain clear records of consent.
What happens if an SMS fails to deliver?
Klaviyo and your SMS provider track delivery status. If a message fails (invalid number, carrier rejection, etc.), that data is logged in your campaign analytics. You can review bounce rates and adjust your contact list or messaging strategy. Some SMS providers offer automatic retry logic for temporary failures.
Can I use SMS and email in the same workflow?
Yes. Klaviyo allows you to build multi-channel workflows where a customer might receive an email, then an SMS follow-up, or vice versa. This is one of the main benefits of integrating SMS—you can orchestrate cohesive customer journeys across channels.
