Direct to consumer marketing looks like an advertising problem and is usually an arithmetic problem. A brand with healthy contribution margin and a repeat purchase can absorb an expensive first order and grow; a brand without either is buying revenue at a loss and calling it growth. Agencies rarely open with that distinction because it decides whether they can help you at all. This page sets out the numbers that should govern the brief, what a competent partner does with them, and the compliance edges that catch consumer brands after the marketing has already worked.
The two numbers that decide the brief
Contribution margin per order and payback window govern everything else. Contribution margin is what remains after cost of goods, payment fees, shipping, packaging and returns, which is a materially smaller number than gross margin and the one an acquisition budget is actually spent from. Payback window is how many orders or months it takes to earn that acquisition cost back, and it determines how much cash the growth requires. A brand with thin margin and no repeat purchase does not have a media problem, it has a product economics problem, and no agency can buy its way out of that. Bring both numbers to the first meeting. An agency that does not ask for them is planning to optimise a platform metric instead, and platform-reported return on ad spend has a well-known habit of exceeding what the bank account shows.
Creative volume is the real deliverable
On the major social platforms, targeting is largely automated and creative is the lever that remains. That makes the practical question for any prospective agency simple: how many distinct concepts, and how many variations of each, will you ship per month, and who makes them. A partner shipping a handful of assets a month is a media buyer with a design habit; a partner running a genuine creative pipeline has a brief format, a testing framework, a source of user generated footage and a graveyard of losers it can show you. Ask to see the losers. Ask how they source real customer footage and what usage rights they secure, because the rights question becomes urgent the moment a winning asset needs to run for a year. Ask what they do when a concept fatigues, since the answer separates iteration from starting over every quarter.
Retention is not a separate department
Acquisition economics improve fastest when the second order gets cheaper, which is why email, messaging and subscription design belong inside the same conversation as paid media rather than in a separate quote. The mechanics matter and so do the rules: the FTC's mail, internet or telephone order merchandise rule governs how quickly you must ship or notify, and any subscription or automatic renewal offer needs clear disclosure of the terms and a straightforward way to cancel. Brands that treat these as legal boilerplate discover them at the moment their retention programme starts working. A good partner will read your checkout and your cancellation flow before it reads your ad account, because a strong offer with a hostile cancellation path produces chargebacks and complaints that cost more than the incremental orders were worth.
What to ask before signing
Ask how they measure incrementality, and accept holdouts, geo tests or a clean pause test as answers while treating last-click attribution as a red flag on its own. Ask who owns the ad accounts, the pixels, the creative files and the customer data, and get the answer in the contract rather than the pitch. Ask what percentage of the fee is media buying versus creative production versus strategy, then compare quotes on that split rather than on the headline number. Many brands eventually consolidate this with search and content under one digital marketing and SEO services retainer, which works when the reporting still separates channels, and fails when a single blended figure hides the channel that stopped working.
Questions people ask about dtc marketing
Should we pay a percentage of ad spend?
Only with a floor and a ceiling. A pure percentage rewards spending more, which is fine while payback is healthy and dangerous when it is not. Hybrid models with a base fee plus a smaller variable component align better, and flat fees work best when creative production rather than media management is the bulk of the work.
How much creative does a DTC programme need?
More than most brands budget for. Plan for a steady flow of distinct concepts rather than occasional big productions, because concepts fatigue on a schedule measured in weeks. The agency's answer to how many they will ship, and who produces them, is a better predictor of results than anything in the strategy section.
Is platform-reported return on ad spend trustworthy?
It is directionally useful and systematically flattering. Compare it against your own blended figure, meaning total revenue divided by total marketing spend, and against a periodic incrementality test. Where the two diverge sharply, believe the bank account and ask the agency to explain the gap rather than to re-cut the dashboard.
When is an agency the wrong answer?
When contribution margin cannot support any acquisition cost, when the product has no repeat purchase and no referral, or when the budget is small enough that the fee consumes most of it. In those cases spend on product, price and organic channels first, and revisit paid acquisition once the arithmetic works.
