SmartMailers turn your direct mail into a performance channel — fully automated and personalized using real-time events from Shopify and Klaviyo. Just like you’d set up an email flow, you can now trigger a physical postcard to send when someone browses a product, abandons a cart, places an order, or lapses as a customer.

Whether you’re reactivating a high-value customer or following up after a browse session, SmartMailers deliver the right message — at the perfect time — right to their mailbox.

What makes SmartMailers powerful:

• 100% automated direct mail flows

• Hyper-personalized content pulled from customer data

• Triggers that mirror your email and SMS strategy

• Layered with SnapCapture™ for real-time engagement tracking and full visibility into who was mailed

SmartMailers can run quietly in the background or support high-intent moments like product launches, restocks, or re-engagement pushes. You can treat them as one-time sends or build out entire multi-touch journeys, combining email, SMS, and direct mail for maximum impact.
