Introducing: Treet Klaviyo Integration

See how our new Resale Segmentation Integration helps you identify, engage, and convert resale customers—directly inside Klaviyo.

Product Release

Your Resale Audience, Visible and Actionable

Smart brands don’t just launch resale for sustainability points. They’re making it a core part of their ecosystem, driving significant new revenue and recovering margin that would otherwise be lost.

But once resale is up and running, one question comes up again and again:

Who exactly are these resale customers, are they one-time buyers or repeat loyalists, and how do you convert them into the latter?

That question is harder to answer than it should be. Until now.

Resale Data, Integrated Where You Need It

Our Resale Segmentation Integration for Klaviyo and solves a problem we hear from brands every week:

“I wish I could see who my resale shoppers are inside the tools I already use.”

Now you can.

Every time someone signs up, buys, or sells on your resale site, their profile in Klaviyo and Shopify updates automatically. They’re tagged as a resale buyer, seller, or both, so you always know who’s who.

No manual exports. No messy spreadsheets. No separate lists to manage. Your customer data stays clean, synced, and ready for your team to act on.

‍

Why This Matters

With this integration, resale becomes part of your retention and loyalty strategy. You can:

Identify your top resale buyers and invite them to shop full price.
Nudge first-time sellers to list again.
Welcome new resale shoppers into your broader community with an offer that fits.
Reconnect with lapsed customers who engage through resale.
Target specific communities with things they care most about, like sustainability and discounts.

All of this happens automatically. No extra work for your team. Just clean data that helps you drive repeat revenue and deeper loyalty.

Proven to Drive Loyalty and Margin‍

This isn’t theoretical. We see it every day in the data:

Resale consistently brings in net-new customers who wouldn’t have bought otherwise.
Those shoppers spend one average 2.5 times their store credit on additional purchases.
Portland Leather Goods, for example, has proven how resale reinforces the cycle of buying, then reselling to earn credit to buy again, creating a loyalty loop that turns resale buyers into repeat customers.

The brands that do this well treat resale shoppers as part of their core community. They use real data to market to them, not guesswork.

Built for Where You Operate

Today, this segmentation works with Klaviyo and Shopify because that’s where most of our brands already operate.
