Smarter Direct Mail, Powered by Klaviyo Events

Our Klaviyo integration builds on BirdseyePost's SmartMailers technology, which automatically sends personalized postcards based on real customer behavior. The same powerful automation you know from our Shopify integration is now available through Klaviyo's robust event system.

Core SmartMailer Templates (Available via Shopify and Klaviyo)

• Abandoned Cart Recovery – Send mail customers who left items behind

• Winback Campaigns – Re-engage dormant customers with physical mail

• Welcome Series – Make powerful first impressions with new subscribers

• Thank You Notes – Show appreciation to your best customers

• VIP Recognition – Reward high-value segments with exclusive offers

• Email Unsubscriber Recovery – Stay connected when digital channels fail

• Anniversary Campaign - Send mail to customers after their one-year purchase anniversary

• Replenishment Reminder - Send a reminder letter after their product is consumed

New Klaviyo-exclusive SmartMailers:

These advanced triggers leverage Klaviyo's email engagement data for unprecedented targeting precision:

• Unread Email SmartMailer
  Send a physical postcard when a subscriber hasn’t opened your emails in a while. Great for reactivating disengaged contacts.

  
  

• Email Engaged but Didn’t Buy SmartMailer
  Target people who opened or clicked an email but didn’t convert—with a direct mail nudge that drives them back to your store.

  
  

• Browse Abandonment
  Send targeted mailers 5 days after browse abandonment if no purchase is made. Capture customers who showed interest but didn't add items to cart.

  
  

• Churn Prevention
  Proactively reach customers with high likelihood of churn based on Klaviyo and Shopify behavioral data. Stop customer loss before it happens with timely direct mail intervention.

Unified Profiles Across BirdseyePost, Klaviyo, and Shopify

The BirdseyePost + Klaviyo connection features bidirectional profile sync, ensuring your customer data stays perfectly aligned across platforms. This means no more manual exports, real-time event synchronization, and a unified customer view across all your retention tools.

Your Klaviyo customer profiles automatically flow into BirdseyePost, while direct mail engagement data flows back to Klaviyo for enhanced segmentation and analytics.

Why It Matters

Most direct mail solutions require clunky workarounds or complex setup to connect with Klaviyo. BirdseyePost delivers something different: a true native integration that brings direct mail into your existing retention workflows without adding complexity.

What makes us different:

• Native Klaviyo integration (no third-party connectors required)

• Real-time automation based on customer behavior

• Easy-to-configure SmartMailers that work out of the box

• Full campaign management handled for you

• One-to-one engagement tracking with SnapCapture, so you can see exactly which Klaviyo profiles engaged with your mailers

As brands increasingly combine digital and physical touchpoints for retention, this integration creates a seamless omnichannel experience that drives real results.
