Can you use Klaviyo for SMS marketing?
Quick Answer: Yes. Klaviyo includes built-in SMS and MMS marketing alongside email, available in the US, UK, Canada, Australia, and other supported countries. SMS messages can be sent as standalone campaigns or embedded within automated flows for abandoned cart recovery, shipping notifications, and promotional offers.
Using Klaviyo for SMS Marketing
Klaviyo provides native SMS and MMS marketing as part of its platform, integrated directly with email campaigns and automation flows. As of April 2026, Klaviyo SMS is available in the US, UK, Canada, Australia, New Zealand, and several European countries.
SMS Flow Automation
SMS messages can be added to Klaviyo Flows (automated sequences) alongside email steps:
- Abandoned cart SMS — Send a text reminder with a link back to the cart after a configurable delay
- Welcome series — First SMS sent immediately after opt-in, followed by email nurture
- Shipping notification — Text updates when orders ship, with tracking links
- Post-purchase review request — SMS request for product review after delivery
- Win-back — Re-engage inactive customers with SMS-exclusive offers
SMS Campaigns
Standalone SMS campaigns can target segments based on:
- Purchase history and predicted next order date
- Email engagement (send SMS to subscribers who do not open emails)
- Geographic location (send during local business hours)
- Custom properties and tags
MMS Support
Klaviyo supports MMS (Multimedia Messaging Service) for sending images, GIFs, and branded media alongside text. MMS messages have higher engagement rates but cost more per message than plain SMS.
Consent and Compliance
- Built-in TCPA compliance tools for US messaging
- Separate SMS consent collection (cannot use email opt-in for SMS)
- Automatic quiet hours enforcement (no messages between 8 PM and 11 AM local time by default)
- One-click unsubscribe handling with STOP keyword processing

Klaviyo SMS pricing is credit-based:
- 1 SMS (US) = 1 credit; 1 MMS (US) = 3 credits
- International SMS rates vary by country
- SMS credits are purchased separately from email plan
- Plans start at $15/month for 1,250 SMS credits
Setup Steps
