## Summary

Nathan Perdriau is most useful for connecting paid media, retention and profit into operating decisions for e-commerce brands.

- Best for: DTC apparel brands spending roughly $250k+ a month on paid media needing retention and Q1 returns planning.
- Not for: Brands seeking fixed sponsored LinkedIn or YouTube placements with published rates and consumer reach.
- Check first: Confirm whether paid partnerships are available and on what terms.

### Takeaways

- Retention sets the ceiling on acquisition spend, and email and SMS come last.
- Judge paid media on acquisition MER, not blended MER.
- Returns and taxes distort MER, especially in January; check return rates by SKU.

## Main ideas

- **Retention is the ceiling on acquisition spend, and email and SMS come last**: Perdriau argues that most e-commerce brands reach for email and SMS when the real constraint lies in product, customer experience, acquisition quality and unit economics. They prefer lifetime gross profit over 30, 90 and 180 days to revenue-based LTV, with a CAC target backed out from LTGP, and place owned channels last in the retention hierarchy. First-to-second-order conversion is named as the usual binding constraint.
- **Judge paid media on acquisition MER, not blended MER**: Perdriau recommends starting with a first-time-customer P&L, removing all returning-customer orders so acquisition performance stands alone. Net revenue is gross revenue minus discounts, returns and shipping collected, with each layer treated as a signal about demand quality. They name acquisition MER—new-customer revenue divided by ad spend—as the paid media efficiency metric, because blended MER moves with repeat buying and can hide a weak month.
- **Run a dynamic MER target around a fixed acquisition MER guardrail**: Perdriau argues that acquisition MER should stay stable while blended MER moves month to month with returning-customer revenue, driven by non-paid levers such as product launches, customer activations, email and SMS cadence, loyalty and promotions. The prescription: lock an acquisition MER guardrail, spend up in high-conversion months until acquisition MER returns to target, pull back in soft months, and grade past months against trailing acquisition MER. When the model shows MER too low for profitability, add returning-revenue levers rather than only cutting spend.
- **Returns and taxes distort MER, especially in January**: Perdriau argues that Shopify's default total sales figure subtracts returns and adds shipping and taxes, so it should not be indexed against ad spend. Taxes are a flow-through expense, and returns swing MER independently of the demand paid media generated. The fix: calculate MER on gross revenue before returns, track returns separately, then review each SKU and stop pushing products whose return rates have risen.
- **In a cash crunch, argue efficiency rather than budget**: Perdriau describes a panic loop: a CFO needs cash, net profit is down, media is cut, revenue falls short, inventory does not clear and cash gets worse. They argue the debate should shift from budget to a survival contribution margin: work backwards from the cash needed in the next 30 to 60 days, identify stock that must sell through, set the lowest acceptable contribution margin, and spend only to that line.
- **Agencies should model incrementality to set media budgets**: Perdriau argues that an agency should help set Meta and Google budgets because it can model incrementality, how spend translates to revenue, how revenue flows to profit contribution, and where diminishing returns sit on each platform. They endorse a four-layer method: incrementality studies, platform-level profit frontiers, seasonality adjustments, and a qualitative layer for launches, collaborations, new markets and pricing changes. They reject percentage increases on last year's spend paired with an assumed ROAS.
- **Marketing and finance need to speak each other's language**: Perdriau argues that marketing KPIs such as ROAS, click-through rate and average CPC do not show what each incremental pound returns in contribution profit, and that forecasts built on ROAS expectations do not actualise. They frame the CFO-versus-CMO fight as a communication and training problem: teach marketers contribution margin, CAC payback and incremental ROAS; have each side sit in the other's meetings; agree on contribution profit as the north star; and forecast together.
- **US expansion is a pricing and readiness problem, not a creative one**: Perdriau warns Australian brands that the US market is the fastest way to kill a healthy business if treated as a bigger version of home. The arithmetic: CPMs roughly double, so copied campaigns double acquisition cost, while US average order value is higher, making price the lever that closes the gap. The readiness test is five ads that have each spent over 200,000 in the home market.
- **Structure and financial alignment matter more than new tactics**: Reviewing their predictions, Perdriau concludes that most value came from better forecasting, incrementality thinking, financial alignment and systems rather than shiny new tactics. The same theme runs through their Meta account advice: the breakdown effect means the highest-ROAS ad is usually overfunded, and account structure should change with monthly spend rather than chase platform ROAS.

## Brand relationships

- **Blue Sense Digital** (employment)
- **KOOKAI** (client)
- **DECJUBA** (client)
- **2XU** (client)
- **VINOMOFO** (client)

## Partnerships

Nathan Perdriau's posts do not set out a brand-sponsorship or sponsored-content offer. The commercial relationships they describe are their agency and teaching. The posts present Blue Sense Digital as a global e-commerce consultancy and paid-media agency working with founders and operators. It manages paid media for 8–9 figure consumer brands including KOOKAI, DECJUBA, 2XU and VINOMOFO, with more than $200M in ad spend and roughly $2B in annual GMV managed, and about $300M a year in ad spend, close to half of it in the US. For a scaling DTC brand, the free-audit and consulting offer is the only route to engage them described in the posts. It is framed as an ongoing managed-service relationship, not a one-off sponsored placement. One post also outlines a hiring and referral programme for performance marketers, focused on staffing the agency rather than brand partnerships. Their public output is otherwise educational: LinkedIn posts for brand operators, a YouTube channel, and long-form masterclasses co-hosted with Angus Cowan on retention and structuring a Meta ad account, aimed at brands running at sub-$50k, $50–250k and $250k+ per month. Before engaging, ask for rates, deliverables per format, exclusivity, disclosure practice, production timelines and approval steps. The posts do not describe a sponsorship product or a partnership inquiry page separate from the agency's general contact route.

## Alternatives

- Angus Cowan: Choose Angus Cowan when the need is mostly owned-channel retention execution: building or rebuilding the Klaviyo account, fixing pop-up capture, mapping first-to-second-order flows, and running win-back and reactivation segmentation. The two items are a full Klaviyo flow system organised around the F1/F2/F3 customer journey, and a pop-up form masterclass that treats pop-ups as the highest-leverage part of an e-commerce email account. If the brand's flows are broken or missing, this work is a closer fit than a strategy-level retention argument.
- Taylor Lagace: Choose Taylor Lagace when the brand wants a bottom-up forecast that converts business goals into ad-account targets: an aMER target applied across channels, a 28-day target reconciled to a 7-day click target through a delayed-attribution multiplier, and product-level targets tied to first-purchase contribution margin rather than a blended ROAS. Two posts walk an 11-step system end to end, name consumer clients the method has been used with, and show how a forecast exposes the gap between what a founder wants and what the current trajectory delivers.
- Robin Tesselaar: Choose Robin Tesselaar when the need is Google-side profitability rather than retention: deciding whether an account is genuinely profitable after cost of goods, shipping, returns and fulfilment; setting break-even ROAS against actual margin; checking branded versus non-branded split; reading new-customer share in Performance Max; and splitting asset groups by margin. The two posts name the specific checks to run and the metrics to optimise instead: POAS and new-customer acquisition cost.
