Direct Mail Meets Your Marketing Stack: The Paperplanes Platform Built for Klaviyo and Shopify

For most brands, direct mail isn’t a formal part of their marketing stack – it’s a side project considered separately, leaving guesswork around whether it’s actually working.
Paperplanes has always set out to change that: to make direct mail a channel you can trigger, track and optimise the same way you would email or SMS. Our native integration with Klaviyo and Shopify, plus a redesigned platform built specifically for marketers, makes direct mail easier than ever to bring real value to your omnichannel strategy.
Here’s what we offer, and why it matters.
We’re live on the Klaviyo App Marketplace
Paperplanes is available on the Klaviyo App Marketplace, meaning any brand using Klaviyo can connect Paperplanes directly from their Klaviyo account . No development work, no custom API integration, no waiting on an engineering ticket needed.
Once connected, Klaviyo becomes the trigger and Paperplanes becomes the channel. That means direct mail can now sit inside the customer journeys you’ve already built, with little extra work needed. A postcard triggered by an abandoned cart, a welcome mailer for a new customer, a win-back campaign for someone who’s gone quiet can all delivered automatically from the same flows and segments you’re already built and used to send email and SMS.
Most importantly, this isn’t a feature limited to existing Paperplanes clients. Anyone using Klaviyo can now install the app, explore the platform, and even order sample mailers to see the quality and format for themselves before committing to a campaign. It’s the easiest way feel and experience direct mail for yourself, and as a part of your marketing mix.
What the integration unlocks:
- Trigger direct mail from existing Klaviyo flows and segments, using the customer data you’re already collecting
- Keep attribution and reporting in one place, alongside your email and SMS performance
- Install directly via OAuth from the Klaviyo Marketplace so you can go live in minutes
Native Shopify integration
Shopify merchants get the same easy install: if you sell on Shopify, direct mail campaigns are built on your store data, with no middleman integration required. We’ve made sure direct mail works seamlessly with your existing tech stack rather than around it – pulling your product and customer data automatically to target the right customers with the messages you want, without you lifting a finger.

A platform redesigned for marketers, not developers
Alongside the integrations, we’ve rebuilt the Paperplanes platform interface from the ground up. The goal was simple: strip out the complexity that made direct mail feel technical, and make it feel like a marketing tool.
The Paperplanes platform difference:
- A cleaner design system. Updated colours, clearer typography and a simplified layout replace the denser, more technical interfaces seen previously.
- A dashboard built for a quick read. Active campaigns, pending campaigns, total campaigns and total mailers sent are all visible at a glance, alongside a campaign-type breakdown so you can see exactly where your mail budget is going.
- Everything in one place. Campaign performance tracking now lives alongside campaign management, so you’re not jumping between tools to see what’s working. Simply click, mail, then track, all inside the same platform.
- Built for the integrations you already use. Our interface is designed around Klaviyo and Shopify from the ground up, rather than having integrations bolted onto an existing system.
All of this makes using Paperplanes easy and effective: targeted, trackable direct mail that gets triggered by real customer data. And, we’ve revolutionised how quickly you can see it, manage it and act on it using our platform.
Why this matters for your marketing
Direct mail historically had a perception problem: thought to be slow, hard to measure, and disconnected from the rest of a brand’s marketing activity. However, the native Klaviyo and Shopify integration remove the technical barrier to entry. A simplified, marketer-first dashboard removes the usability barrier. Together, they make direct mail as simple to run as any other channel. The steps are the same: build the audience, trigger the send, track the result.
