An agency in Haarlem specialized in retail and online stores struggled with seasonal peaks: Black Friday, Christmas and the summer sales caused chaos every single time. For three months of the year the team worked 60+ hours a week; the rest of the year was quiet. There was no scalable system.
Senly's campaign planning let the team schedule campaigns 3 months ahead. For the first time, Black Friday was fully planned in advance and executed automatically. During the peak, the team worked an average of 12 hours a week less, with better results for clients.
"Black Friday was a disaster every year — we worked ourselves into the ground and still made mistakes. This year we planned everything back in September. On the day itself, we drank coffee and watched it unfold."
