Quick iteration
AI is bad at net new content, but good at slight variations. Keep your brand feel while quickly testing different offers, actions, and timing. Never have to wait for the next version.
Infinite retention testing
Zaymo runs the setup, the statistics, and the read-out continuously. You keep the strategy, and every test is scored on gross profit.
Testing with
Email testing is hard
Lifecycle flows generate your highest-margin revenue, yet they get the least experimentation. Testing in Klaviyo is complicated and so doesn't end up happening.
- No time to set up: Flow logic, list splits, and cohort tagging take hours you don't have.
- No idea what works: Subject lines don't move the needle. Agencies and consultants bring ideas but cost $$$ and are slow.
- No way to measure LTV: Measuring message opens instead of cohort LTV means you never know if a test actually drove bottom-line growth.

What We Test
Abandonment Flows: Discount depth vs. value-add incentives, urgency triggers, dynamic product recommendations, subject lines, and send delays.
Objective: Capture high-intent shoppers while protecting gross margin.
Typically increases abandonment gross profit 10–20%.
What We Test
Replenishment & Reorder Flows: Personalized timing based on product, multi-pack upsells, cross-sell bundling, and subscription transition messaging.
Objective: Increase LTV through increased repurchase rate and increased subscription take rate.
What We Test
Upcoming Order / Pre-Shipment: One-click add-ons, swap suggestions, frequency adjustments, and brand engagement messaging before subscription renewals.
Objective: Increase LTV and reduce churn.
Infinite variables: From subtle copy tweaks to complete offer overhauls, Zaymo handles end-to-end variation testing across copy, offers, creative, and flow timing. You bring the hypothesis, or let our agents surface one, and we’ll build the experiment.
How it works
A testing program without a testing team. You set the intent and the guardrails. Zaymo runs everything between hypothesis and revenue.
-
Hypothesis
Bring a strategic intent, or let Zaymo mine your flow history for one.
-
Generation
Subject lines, copy, imagery, CTAs. On-brand by construction.
-
Deployment
Wired into live flows with cohort tagging and integrity checks intact.
-
Optimization
Thompson Sampling shifts traffic to winners. LTV tracked to 90 days.
-
Learning
Every result narrows the next hypothesis. The loop tightens.

Retention deserves a lab
Acquisition marketers have spent a decade becoming CRO scientists. Every ad headline, landing page, and offer gets tested, measured, and continuously improved.
Retention never got those tools. Lifecycle flows are shipped on gut feel, and almost no one measures what a message change does to long-term customer value.
We're building Zaymo to bring autonomous testing rigor to retention. You set the strategy, Zaymo runs the lab.
