## Summary

Corto Stergard is most useful for practical Klaviyo ecommerce email systems, lifecycle flows, segmentation, acquisition, and AI-assisted execution.

- Best for: DTC ecommerce brands already on Klaviyo needing clearer lifecycle email priorities and specific flow improvements.
- Not for: Paid creator sponsorships with guaranteed reach, rate cards, or demographic audience commitments.
- Check first: Confirm paid partnership terms, inquiry route, and audience analytics before outreach.

### Takeaways

- Klaviyo Growth OS built across more than 50 accounts.
- Find biggest opportunity first, then fix things in that order.
- AI handles repetitive analysis and execution; marketer keeps strategy and approval.

## Main ideas

- **Lifecycle flow structure is reusable; copy and brand change, but the underlying pattern often does not**: Stergard argues that the strongest ecommerce lifecycle programs rarely start from a blank page. They say this conclusion comes from reviewing hundreds of ecommerce emails and $50M+ in ecommerce revenue. What varies is the copy and the brand, not the structure: when each email lands, how long to wait between messages, when to introduce an offer, where social proof belongs, when education becomes conversion, and how many emails a flow needs. The stated purpose is not to copy another brand, but to avoid rebuilding every flow from scratch.
- **Find the biggest opportunity first, then fix things in that order**: Stergard prioritizes diagnosis over optimization. They describe the Klaviyo Growth OS as looking across flows, campaigns, customer behavior, segmentation, Shopify data and revenue performance, then deciding what to work on first. The goal is to find the biggest opportunities, fix the right things first and move faster with AI. They claim the process saves 25+ hours a week, after building it across more than 50 Klaviyo accounts. The argument: priority order, not channel-by-channel tidying, creates the gain.
- **AI handles repetitive analysis and execution; the marketer keeps strategy and approval**: Stergard describes configuring Claude Code as an execution engine rather than a writing assistant. In that setup, Claude analyzes a Klaviyo account, finds opportunities and runs CRM workflows across flows, campaigns, segmentation, deliverability and analytics, while the marketer sets the operating rules and reviews the output. Claude handles repetitive work; the strategist keeps the strategy. Separate workflows run in parallel and can be reused across campaigns, flows or accounts. A second post states the same division at a higher level: Claude for strategy and iteration, Klaviyo for capture, automation and revenue.
- **Plan the whole month in one process, then stop at Klaviyo-ready concepts**: Stergard argues that the planning layer can be compressed: what used to take separate rounds of strategy, copy and creative direction can happen in one session, producing the full monthly CRM machine rather than a single email. They distinguish this from AI writing one email: a CRM strategist builds the month around what a brand should send, when and why. The handoff is clear: the result is concepts ready to recreate inside Klaviyo, not finished assets in the account.
- **Fix the acquisition layer before optimizing the flows it feeds**: Stergard argues that $1M in traffic is worthless if you cannot capture the visitor, and that a weak acquisition layer leaves every downstream flow with less to work with. In their account, most brands obsess over what happens after someone joins the list, while the real leverage sits before the first email is sent. The practical consequence: prioritize capture, then optimize flows once enough people are entering the system.
- **Offer framing adapted from Alex Hormozi’s growth rules**: Stergard takes three growth rules from Alex Hormozi’s $100M material, credited in the post to Hormozi, and applies them to CRM: reveal what your CRM is doing wrong, give people a taste of the results they could get, and pull one high-value piece of the offer so they want the full thing. They argue that most CRM strategies fail at all three by overwhelming people with data, dashboards and recommendations without making clear what matters. The approach is diagnostic-first: expose the problem before proposing the work.

## Partnerships

Corto Stergard's six LinkedIn posts each close by offering a free resource: a Claude Code setup for Klaviyo account analysis and task execution, a monthly CRM campaign builder, the Klaviyo Growth OS, a lifecycle flow swipe file, an email acquisition playbook, and a CRM Skill Vault. Each post describes a system, then points readers to a packaged guide or file—a lead-magnet handoff, not a paid placement offer. The posts publish no rate card, sponsorship tier, editorial-review policy, partnership inquiry route, price, deliverable specification, timeline, or commercial terms. A brand considering a paid engagement should ask whether they accept paid work and confirm scope, deliverables, exclusivity, pricing, and turnaround directly.

## Alternatives

- Meilech Biller: For a DTC email brand whose bottleneck is operational AI adoption across the CRM and marketing process, Biller is a stronger alternative to a lifecycle-flow specialist. Biller’s posts describe using Claude to set up CRM and project systems, onboarding forms, documents and emails; connecting project management so tasks are created automatically; and having Claude review the CRM, project chats, WhatsApp and email daily to decide the best next action for each lead. Biller also built a deliverability dashboard that gives Klaviyo users a simple view of email deliverability. That combination matters when the brand wants an AI-assisted operating layer before rewriting lifecycle flows, or when deliverability may be limiting Klaviyo revenue.
- Noah Haynes: For a DTC email brand that already has basic lifecycle flows and wants a retention programme built around list growth, sending cadence, campaign merchandising, missing flows and KPI definitions, Haynes is a strong alternative. Their posts give concrete thresholds: send at least three campaigns a week even with a small engaged list under 15k; keep segment buckets from crossing; treat angle as more important than design; maintain 40–50 essential flow emails across welcome, site abandon, browse abandon, cart abandon, checkout abandon, branded transactional, first-time thank-you, returning thank-you, immediate upsell, general winback and sunset; and track cohort LTV, returning customer rate, and customer retention rate in percent and dollars. Haynes also gives a campaign plan for dead stock: a two-to-four campaign slow-mover sequence for stock older than six months, with an offer, merchandising the slowest movers first, spreading the sends out, and repeating the tactic.
- Alejandra Salomon: For a DTC brand whose Klaviyo revenue is flat while repeat purchase or retention is weak, Salomon is a strong alternative to a flow rebuild. Their posts focus on diagnosing whether lifecycle email is being asked to fix a problem that starts upstream in acquisition, product or customer experience. Salomon recommends tagging customers and comparing cohorts, then showing leadership where behaviour starts to change: if one acquisition channel, offer or messaging has worse repeat rates; if discount-acquired customers churn faster; or if cancellations consistently mention product experience, pricing or how quickly the product is actually used. The argument is that retention is downstream of the entire customer experience, and that a perfect welcome flow, segmentation, personalisation, replenishment timing or winback cannot save a customer experience that was not worth returning to.
