With BirdseyePost’s direct integrations for Shopify and Klaviyo, your direct mail becomes as intelligent and automated as your digital channels — but with far higher visibility and staying power.

This isn't a one-way push — it's a full two-way data sync. We'll not only pull customer and event data from your Klaviyo and Shopify accounts to trigger mailers, but also push engagement data from postcards back into your marketing tools. That means your email flows, custom segments, and retargeting audiences get smarter with every scan or purchase driven by direct mail.

You’ll see who received a postcard, who scanned their unique QR code, who converted, and when — all linked to the right profile in Klaviyo or Shopify.

With two-way sync, you can:

• Trigger direct mail from key events like viewed product, abandoned checkout, or lapsed purchase

• Use Shopify purchase history or Klaviyo segments to build powerful SmartMailer™ flows

• Personalize postcards with real-time customer data and dynamic content

• Automatically sync SnapCapture™ engagement — scans, visits, and conversions — back into Klaviyo profiles or Shopify customers

• Enrich existing audiences with new behavioral data captured from your mail

This makes BirdseyePost a true extension of your digital marketing stack — not a siloed channel. You can create automated, multi-touch customer journeys that combine email, SMS, and direct mail — all working together, all tracked.

Why marketers love it:

• No manual uploads or exports

• Keeps audiences and campaign logic centralized in your source of truth

• Enables full-funnel attribution, including offline-to-online conversion tracking

• Turns direct mail into a performance channel that can scale

Whether you’re recovering lost sales, nurturing VIPs, or scaling cold outreach, our Shopify + Klaviyo integration ensures every direct mail touchpoint is smart, timely, and fully measurable.
