Most fashion brands treat a product drop like any other launch day. They turn on a sales campaign, send one email, and hope the new collection moves. The brands we work with at Skaleit do the opposite. They start running ads two to four weeks before the drop, build a heated waitlist, and then convert that waitlist on launch day with a separate purchase campaign.
In the last 30 days, one of our fashion clients spent $235K and generated over $1M in sales at a 4.31 ROAS. Another spent $70K and pulled $500K+ at 7.94 ROAS. Both follow the same playbook we are about to break down.
TL;DR
Selling out a fashion drop on Meta ads requires two separate campaign phases, not one. Phase 1 (pre-launch, 30 to 14 days out) runs three campaigns to capture leads and warm up a waitlist. Phase 2 (launch day) runs a single sales campaign split between retargeting that waitlist and broad prospecting. The entire system is designed to generate scarcity-driven demand before the product is even live.
Why Most Fashion Drops Underperform
When a drop only relies on launch-day ads, you are asking Meta to find buyers, convince them to buy, and close them in the same 24 to 48 hours that your stock is live. That compresses every step of the funnel into a window where CPMs are high, your creative is brand new, and the algorithm has no warm audience to work with.
The two-phase system at Skaleit splits that work across time. Lead-gen campaigns in the weeks before the drop pre-qualify your buyers cheaply, build first-party data into Klaviyo, and let Meta’s pixel learn your audience well before the sales pressure hits. By launch day, you are no longer cold-prospecting. You are converting an audience that already knows the drop is coming and has been told there is limited stock.
Phase 1: The Pre-Launch (Starts 30 to 14 Days Before Drop)
The pre-launch phase runs three campaigns simultaneously, each with a different job. Plan to start at least two weeks out. Trying to compress this into the seven days before launch is the most common failure point we see.
The three pre-launch campaigns are: a lookalike lead-gen campaign to find new prospects, a retargeting lead-gen campaign for past customers and engagers, and a low-budget reach awareness campaign that warms up everyone who has signed up for the waitlist.
Campaign 1: Lookalike Lead-Gen
This campaign exists to fill the waitlist with prospects who actually look like buyers. Most agencies will tell you lookalikes are dead and you should go broad. That advice is correct for purchase campaigns, but it breaks for lead-gen.
When you optimise a lead-gen campaign for broad audiences, you are telling Meta to find people who will leave their contact info, not people who will buy. The result is a waitlist full of freebie-collectors who never convert on launch day. Build a 0% to 5% lookalike off two source audiences: 180-day pixel purchasers and Klaviyo subscribers who have made at least one purchase. Drive traffic to a landing page offering a launch-day incentive (early access, free gift, or discount code).
Campaign 2: Retargeting Lead-Gen
Run a parallel lead-gen campaign retargeting your existing customer list, past engagers, and add-to-cart abandoners. Same landing page, same offer.
The reason this campaign matters: people who already know your brand convert to the waitlist at a much higher rate than cold lookalikes, and their pixel signal is far cleaner. We have seen retargeting lead-gen sign-ups convert on launch day at 3 to 5x the rate of fresh lookalike leads. Do not skip it.
Campaign 3: Low-Budget Reach Awareness
Once people are on the waitlist (either via the pixel custom event or your Klaviyo list), the third campaign warms them with teaser content. Optimise the campaign for reach and awareness, not for purchase or leads. Keep the budget low, the goal is frequency on a hot audience.
Build the audience by combining two sources: a Meta pixel custom event that fires on the landing page thank-you screen, and the Klaviyo list synced to Meta via the native integration. Using both maximises match rate, since Meta and Klaviyo each occasionally miss events the other catches.
What Pre-Launch Creatives Should Look Like
The two lead-gen campaigns and the reach awareness campaign use different creative formats. Mixing them up is the fastest way to confuse the algorithm and burn budget.
For the lead-gen campaigns, use four creative types: an offer key visual that surfaces the launch-day incentive, a campaign key visual showing teasers of the product (close-ups and hints, never the full pieces, you want curiosity not closure), a warehouse or stock static showing fresh inventory just landed, and founder videos and trailers where you personally invite viewers to join the waitlist.
For the reach awareness campaign, switch to behind-the-scenes content: trucks delivering stock, founder messages typed in the iPhone notes app run as static ads, and a video that explicitly frames scarcity. This is where the magic happens. Tell the audience: “We have 100 pieces and 1,000 people already on the waitlist.” That single message, shown to people who are already on that waitlist, is what turns a passive sign-up into a launch-day buyer setting an alarm.
Phase 2: Launch Day (Sales Campaign Structure)
The pre-launch campaigns shut off on the morning of the drop. From that moment, a single sales purchase campaign takes over, split into two ad sets.
The first ad set retargets the waitlist (the custom audience built from the pre-launch landing page event plus the Klaviyo sync). The second goes broad to capture everyone else who did not make it onto the waitlist but is still in your brand’s prospecting orbit.
Both ad sets drive traffic to a dedicated new drop collection page. Do not mix the new collection with your existing catalogue on the destination page, the algorithm and the buyer both lose focus. The collection page should only contain the drop products.
For the retargeting ad set, layer in urgency: “Your 10% discount is valid for the next 24 hours.” Combined with the scarcity already seeded in the pre-launch reach campaign, this is what compresses sales into the first 24 to 48 hours.
Launch Day Creatives
The retargeting ad set gets one extra creative type the broad ad set does not: ads that remind the waitlist about the specific offer they signed up for, with the urgency timer attached.
Beyond that, both ad sets share the same creative pool. Founder videos announcing the drop and explaining the inspiration behind the collection. Product statics shot flat and on-model. Campaign key visuals (if the drop is a floral collection, your model in a floral setting). And one format most fashion brands still skip: collage photos that combine the model shot with multiple product cutouts in a single image. Inside Meta’s instant experience, this format lets the buyer see the entire drop in a single ad. It works extraordinarily well for fashion.
Scaling After Launch
Once both ad sets are running and the algorithm has data, the only operational task is budget management. Increase spend on whichever ad set holds ROAS above your target. The structural work was already done in the pre-launch phase.
This is the part most fashion brands miss. By the time you are scaling, the heavy lifting is already in your waitlist size, your pixel signal quality, and the scarcity narrative your reach campaign seeded. Launch day is the harvest, not the planting.
What This System Looks Like in Numbers
The two examples we opened with were not anomalies. The fashion brands at Skaleit running this exact playbook consistently produce drops that sell through 70% of stock in the first 48 hours. The 4.31 ROAS at $235K spend and 7.94 ROAS at $70K spend are 30-day averages across the launch window plus the days that follow, where the broad ad set continues to convert on the long tail of the drop.
The system works because it stops asking Meta to do impossible work in compressed time. It hands the algorithm a warm audience, a clean event signal, and a clear sales window.
FAQ
How early should we start the pre-launch phase for a fashion drop?
Between 30 and 14 days before drop day. Less than 14 days and your audience does not heat up enough. More than 30 days and the waitlist gets stale before launch. Skaleit defaults to 21 days for most fashion clients we work with.
Do we need Klaviyo to run this system?
You need an email service provider that integrates natively with Meta. Klaviyo is the standard for fashion ecommerce and what we use for every Skaleit client. Mailchimp and Omnisend also work, but the audience sync quality on Klaviyo is the cleanest we have tested.
What incentive works best for the pre-launch waitlist?
Early access to the drop is the strongest incentive for premium fashion brands, because it preserves perceived value. For mid-market and contemporary brands, a 10% to 15% launch-day discount or a free gift with purchase converts better. Test once per drop, then standardise.
How big should the pre-launch ad budget be?
For brands doing $50K to $500K per month in revenue, allocate 15% to 25% of the drop’s projected ad budget to the pre-launch phase. The rest funds the launch-day sales campaign. The reach awareness campaign inside Phase 1 should always stay low budget (often under $30 per day), it is frequency on a hot audience, not prospecting.
Can this system work for non-fashion ecommerce?
The two-phase architecture works for any drop or limited-stock launch (sneakers, supplements, beauty, even high-ticket home goods). Fashion is where the playbook was sharpened because drop economics map cleanly onto Meta’s algorithm. Other verticals need slight creative adjustments but the campaign structure is identical.
What is the biggest mistake brands make on launch day?
Letting the broad ad set run with no daily cap and burning budget on cold audiences before the retargeting ad set has cleared the waitlist. Always front-load retargeting spend in the first 24 hours, then scale broad as the warm audience saturates.
