Retention systems that build a real business.

We rebuild your Klaviyo and Attentive accounts into revenue engines — lifecycle flows, subscription nurture, campaign calendars, and the deliverability discipline that keeps you landing in the inbox.

The retention gap

Paid gets them in the door. Retention pays the business.

Most nutra brands are sitting on a Klaviyo account running 12% of revenue when it should be running 35%. The flows are generic, the segmentation is lazy, and the campaigns sound like a sale pitch instead of a relationship.

We treat retention as product-adjacent. What happens after someone buys is the part that determines your LTV — and LTV is the part that lets you outbid every competitor on paid.

Every system we build is anchored to subscription retention. We know the exact email and SMS moments that turn a one-time buyer into a three-year subscriber.

What's inside

A full retention rebuild.

Account audit & rebuild

We rebuild Klaviyo or Attentive from scratch — flows, segments, templates, and deliverability — in the first 30 days.

Lifecycle flows

Welcome, abandonment, post-purchase, subscription, win-back, VIP. 14+ flows, tested against your existing benchmarks.

Campaign calendars

Weekly campaign plans built around promotions, product education, and lifecycle moments — designed, copywritten, and scheduled by us.

Predictive segmentation

Segments based on purchase frequency, LTV quartile, subscription tenure, and product affinity — not just "has purchased."

Subscription nurture

Flows designed specifically for subscribers — reducing churn, increasing upsell take-rate, and driving brand loyalty.

Deliverability & compliance

DMARC, DKIM, SPF setup. Monthly list hygiene. Quarterly deliverability audits. You land in the inbox, not the promotions tab.

Retention FAQ

Questions email & SMS founders ask.

Can you work with our existing Klaviyo account?+

Yes. We work inside your account. You retain ownership of your list, your flows, and your historical data. We just make it earn more.

How quickly will we see results?+

Typically inside the first 30 days. Welcome and abandonment flow improvements usually land first, followed by subscription flows and campaign ROI by day 60–90.

Do you also handle copywriting and design?+

Yes. Every email and SMS we ship is designed, written, and built by our team. You approve. We send. You grow.

What about SMS compliance in the US?+

We handle TCPA and CTIA compliance, 10DLC registration, and carrier relations. Non-compliant SMS is how brands get fined or shut off — we don't let that happen.
