Selling direct removes the retailer and hands you their margin, their customer relationship and their logistics problem at the same time. That makes the marketing question unusually arithmetic: what does it cost to acquire a customer, what is left after shipping, payment fees, returns and discounting, and how often do they come back? An agency that cannot hold that conversation is running campaigns without knowing whether they make money.
Contribution margin is the number that governs
Revenue is a poor guide here because the costs that erode it are large and variable: delivery, packaging, payment processing, returns and the discount that got the order. Ask the agency to report acquisition cost against contribution margin per order, not against revenue. If they have never worked that way, they will optimize toward cheap orders that lose money at the second delivery attempt.
Repeat purchase changes what you can afford to bid
A product bought once a year supports a very different acquisition cost from a consumable bought monthly. Establish the repeat pattern from your own order history before setting targets, and separate new-customer campaigns from retention so that returning buyers are not counted as paid acquisition. Mixing them is the most common way paid performance is overstated in this model.
Creative is the main performance variable on social
With bidding and placement automated, the lever left is what the advertisement says and shows, and the constraint is how many distinct concepts can be produced and tested each month. Ask what the creative cadence is, who makes it, and how concepts are chosen and retired. An agency with a strong media reputation and no creative pipeline will plateau within a quarter.
Owned channels are where the margin recovers
Email and messaging to people who already bought are the cheapest revenue in the model, and they are frequently under-built because they are less exciting than acquisition. A flows program covering welcome, abandonment, post-purchase and replenishment should be in the first ninety days. Ask for the deliverability position as well, because none of it matters if the mail is filtered.
Questions people ask about D2C marketing agency
How should a D2C agency be paid?
Flat retainers avoid the incentive to grow spend for its own sake, which is a real risk when the agency's fee tracks media. If a performance element is used, tie it to contribution margin or to new-customer orders rather than to revenue, so that discounting your way to a bonus is not available.
What should we measure in the first ninety days?
Blended acquisition cost across all channels, new-customer acquisition cost specifically, contribution margin per order, return rate by product, and repeat rate by cohort. Anything that cannot be traced to those is a diagnostic metric rather than a result.
Do we still need SEO if paid social works?
Paid channels are rented and their costs rise; organic search, email and a known audience are the assets that reduce dependence on them. The usual sound answer is to run both, and to judge organic on its own contribution rather than on whether it can match paid for speed.
How do we compare agencies with impressive case studies?
Ask for the account they lost and why, and for a client where the numbers did not work. Then ask for a current client in a comparable margin structure that you may contact. Case studies select for survivors, and the two questions above are the fastest way past them.
