Black Week as a Sales Booster – with a Clear Strategy

For T1TAN GmbH, a leading provider of goalkeeper gloves and football equipment, Black Week is one of the most important sales periods of the year. The goal was ambitious: drive more revenue with minimal spend. Traditional channels like email marketing were already in place, but open and click rates were stagnating. The team needed a channel that was more direct, measurable, and high-performing.

The answer: WhatsApp marketing with Chatarmin.

Three Campaigns – One Clear Focus

The team decided to launch three WhatsApp campaigns during Black Week. Each campaign was timed strategically and designed to activate the community with exclusive offers. Key success factors included:

  • Direct customer communication via WhatsApp – personal, attention-grabbing messages
  • Multiple touchpoints across the Black Week to reinforce buying impulses
  • Exclusive deals with clear calls-to-action

Implementation was lean and efficient: with sending costs of only €5,157.83, the campaign went live within days.

Impressive Results Through Precise Targeting

The numbers speak for themselves:

  • €49,060.42 revenue via WhatsApp
  • 9.5x Return on WhatsApp Spend
  • 76.2% average open rate
  • €93.90 average order value

An open rate of over 76% shows that WhatsApp messages are not only delivered but truly noticed. The high order value also confirms that the campaign didn’t just reach people – it drove real purchasing power.

Why WhatsApp Outperformed

With WhatsApp, T1TAN built a direct and measurable connection to its community. Compared to email, response rates were faster, conversion rates higher, and ROI clearly proven. WhatsApp became the channel with maximum impact.

Takeaway – Rethinking Black Week

With Chatarmin and WhatsApp, T1TAN was able to strategically leverage Black Week and significantly increase sales. Three campaigns, one clear goal, and impressive results. This case shows: brands that want to maximize results during peak sales phases should firmly integrate WhatsApp into their marketing strategy.
