Email and SMS

Automated SMS and multi-channel flows

Create SMS, MMS, and multi-channel flows (email and text) that are triggered off of each individual shopper’s behaviors and preferences—like browsing, cart abandonment, order history, order and shipping confirmations, form completions, and more.

  • Create flows quickly with our drag-and-drop flow builder
  • Combine email and SMS messages in the same flows
  • Use preference and behavior-based splits
  • Stay safe with smart sending rules and quiet hours
  • Include dynamic product images from browse and shopping behavior
  • Share a virtual contact card to increase brand recognition
Automation example: One week before expected order, send SMS if consented, otherwise send postcard if predicted lifetime value exceeds $100.

And use that data to create the targeted segments and personalized texts you need to drive sales.

Mixtiles uses email and SMS together to drive almost 40% of revenue

“If I were working on separate email and SMS platforms, it’d leave room for error and result in a disjointed customer experience. By combining email and SMS in Klaviyo, it gives us—and our customers—a lot of value.”
