eCommerce Klaviyo Agency

The core stack: a welcome series (most of its revenue lands in the first 72 hours), three mutually-exclusive abandonment flows — cart, checkout, and browse, each matched to its intent level — post-purchase sequences that set up the second order, and a win-back for customers going quiet. Built with strict filters so a subscriber is never caught in two flows at once.

Two to three per week to engaged segments, whatever your list size — with a content mix of roughly 60% educational, 30% product, and 10% pure sales. The engagement window flexes with your open rates: if opens drop, we tighten the audience rather than send less.

Not if the list is managed. Deliverability problems are usually segmentation problems: we send to engagement windows sized by your actual open rates, filter bounced profiles out of every flow and campaign, and diagnose per inbox provider when something drifts. Volume to people who open is fine; volume to a stale list is how you end up in spam.

A mature program typically lands around 25–30% of total revenue from email. Inside that, the core flows carry known shares of attributed email revenue: the welcome series around 9–15%, abandoned cart 8–12%, browse abandonment 2–5% — which is exactly why we build the automation stack before scaling campaign volume. If your email is under 20% of revenue, there’s usually a specific, findable reason.

Through MKOS.AI — the proprietary platform we built to run the agency. Your email and SMS performance sits next to your ad and Shopify data, real-time and historical, so flow and campaign revenue gets reconciled against what the store actually made — not just what a platform claims credit for. AI analysis flags which flows, campaigns, and segments are pulling their weight and which need work, and every optimization follows from that data. You see the same numbers we do.

Yes, narrowly. Transactional and abandonment SMS earn their cost quickly; for campaigns, only three types are consistently worth the credits — launches, restocks, and sale announcements. We set it up compliant (real consent, quiet hours) and keep it surgical, because SMS goodwill burns fast.

The work is run by Klaviyo experts — flows, campaigns, segmentation, and deliverability are the daily practice of an ecommerce email marketing agency, and retention is half of every growth plan we write. We operate as an independent retention marketing agency rather than a listing in the Klaviyo agency partner directory: you are hiring the operators, not a badge.
