A new revenue stream from email in only 7 days

Hello Retail · March 18, 2026

With Product Agents connected to Klaviyo, Beslag Online started generating net-new email revenue within a week, from customer moments their existing flows couldn’t reach. No flow building. No segmentation. No manual setup.

About Beslag Online

Beslag Online is one of Sweden’s leading online stores for home hardware and interior details: handles, knobs, hooks, door handles, bathroom accessories, lighting, and more. With thousands of products across dozens of styles and finishes, their customers often browse and compare several options before making a decision.

More revenue from customers they already have

Like most retailers using Klaviyo, Beslag Online had their core flows in place: welcome, abandoned cart, post-purchase. But beyond those, making emails specific enough to actually convert is hard. The question was how to go further, reaching customers with the right product, at the right moment, based on what they actually browsed.

Catching the moments standard flows miss

Beslag Online connected Hello Retail’s Product Agents to their Klaviyo account. The agents use customer and product data to decide who to email, what to show, and when, then send automatically through Klaviyo using existing templates. No flows to build, no segments to maintain.

Price Drop for Alternatives Agent

Catches comparison shoppers when a similar product drops in price.

Replenishment Reminder Agent

Nudges each customer when they're likely running low — timed to the individual.

Price Drop for Alternatives Agent

When a product drops in price, it’s not only possible to notify customers who viewed that exact item. This agent also reaches shoppers who browsed similar products in the same category and style, catching comparison shoppers who would otherwise never come back.

Replenishment Reminder Agent

This agent tracks when each customer bought a consumable product and sends a personalized nudge when they’re likely running low. Not a batch email on a fixed schedule. A reminder timed to the individual.

Both agents run through Klaviyo using existing email templates. Nothing to rebuild. They work alongside Beslag Online’s current flows, adding a new layer of revenue.


”Product Agents picked up the patterns we couldn’t act on (comparison shoppers, replenishment timing) and turned them into revenue. The 17X ROI in the first week made it an easy decision to upgrade to a bigger plan.”
