Case Study: How we PROFIT MAXXED NL BEAUTY's Worst (Low Season) Month

August is one of the weakest months for cosmetics brands across Europe as holidays kill retail demand for most niches during the Summer. Nevertheless, for NL BEAUTY, August 2026 became one of the strongest months of the year - highest-performing for campaign revenue, and second in total revenue (only behind a February birthday sale peak). The secret: an exclusive Summer Black Friday built on a single offer

Email is managed across 5 separate market accounts, with a total database exceeding 250,000 subscribers.

The challenge
02 / 05

August works against the calendar

For most cosmetics brands, Summer is usually the lowest season – especially August. For most companies, this a month to absor, not scale & hit peak revenue. However, this time, we decided to aim for the opposite to compensate for the lower demand, by running a Summer BFCM event…

01

Lower seasonal demand

The holiday period pulls the audience away from routine shopping, and buying intent sits at its lowest point of the year.

02

No natural occasion

Most months of the year have various occasions to organize a sale campaign, while August is one of the emptiest months.

03

List health

The volume required meant sending to the full database repeatedly within a single week, including segments normally excluded – exactly where unsubscribe and complaint rates tend to spike.

The objective: run a sale event, at a scale large enough to reverse the month, without damaging the database.

The strategy
03 / 05

Summer
Black Friday

The concept was to import a Q4 retail moment into August. Black Friday carries built-in urgency and a shared understanding of what it means – deep offers, short window, act now.

The event ran for eight days, from 4 to 11 August, across seven emails.

Summer Black Friday was the centrepiece, but not the whole month as the sale was designed to sit inside a full calendar, not replace it.

The highest campaign revenue month of the year

August finished as the highest campaign revenue month of the year, and the second highest month of total store revenue – behind only February, when the brand runs its anniversary sale.

Campaign revenue by month. Revenue figures withheld.

Campaign revenue in August ran 2.6x the monthly average for the year, and 5.4x the year’s weakest month.

Total store revenue by month, attributed and unattributed. Revenue figures withheld.

The sale accounted for 75% of the month’s campaign revenue in 8 days of a 31-day month – earning at roughly 7x the daily rate of a normal month. On its own, those eight days out-earned an average full month by nearly 2x.

Conversion rates ran 4-6x times the account’s normal campaign rate, across 1.52 million emails.

Hot Takes You Can Steal

01

There is always an occasion - you just have to create it.

Demand in a slow month is not fixed. Borrowing a frame the audience already understands gives a promotion instant meaning. Every quiet month can carry an event.

02

Blast the list when it matters.

During major sale events, when high conversion rates are expected, email your full list (unless your initial deliverability is bad). 

03

Double up at peak interest.

Two emails on launch day, eight hours apart, carried a third of the sale. Interest peaks at announcement – spacing sends evenly wastes it.

04

The offer is only half of it - the frame is the other half.

The same 1+1 ran three weeks earlier as a small flash promo and performed like one. Named Summer Black Friday and given a deadline, it did 3.4x. Before deepening a discount, check whether anyone was told it mattered.
