Overview

Why Shopify Brands Choose Bylders

  1. We Focus on Profit, Not JUST Pretty

Our philosophy is simple: if it doesn’t drive profit, it doesn’t go out.
That means every campaign, automation, and flow is designed to increase LTV (Lifetime Value) and ROI — not just look nice in Klaviyo.

  1. Done-For-You Retention Engine

We build the foundation that fuels your brand’s growth:

10+ high-converting Klaviyo flows (welcome, post-purchase, winback, and more)

Campaign calendars that actually sell, not spam

Segmentation strategies proven to drive repeat purchases

Weekly reporting and optimization for ongoing gains

  1. We Guarantee Results — Or You Don’t Pay

We’re so confident in our systems that we offer a 90-Day Profit Guarantee.
If we don’t increase your revenue in the first 90 days, you don’t pay a cent.

  1. We Integrate Like a True Partner

We don’t just plug into your Klaviyo.
We integrate into your marketing stack, product launches, and overall brand strategy — helping you turn owned channels into your highest ROI growth engine.

Real Shopify Results

💥 Heirloom Coffee — We took Heirloom from zero to 30% of all revenue driven by email, pushing LTV and retention to unlock sustainable growth.

💥 Fazit Beauty — After their viral Taylor Swift moment, we helped build a full retention machine that turned one-time shoppers into loyal, repeat customers.

💥 Vant Panels — We stabilized their retention engine and scaled email-attributed revenue to over 50% of total sales, setting a new benchmark for performance.

These aren’t one-off wins.
They’re frameworks — built, tested, and refined across Shopify’s top DTC brands.

What Makes Bylders Different

There are hundreds of Klaviyo “experts” out there.
But few have the real-world experience building and running Shopify brands at scale.

We know how email decisions impact your cash flow, ad performance, and growth trajectory — because we’ve lived it.

That’s why top Shopify founders trust Bylders to handle their most valuable channel: retention.
