Success stories

How sonnenklar.TV's move to charles halved their Meta costs and increased customer engagement
-48% reduction in Meta advertising costs
+61% increase in click-through rate (CTR)
75.5% highest click-through rate (CTR)

 

sonnenklar.TV is a German travel shopping channel specializing in vacation deals, operating via television, online, and mobile platforms. They also operate physical travel agencies for personal consultations and bookings.

WhatsApp was already an established customer engagement channel for the company, but they were limited in the level of personalization and cost-optimization they could achieve with their existing provider.

By partnering with charles, sonnenklar.TV is able to significantly reduce their advertising costs while increasing engagement through more targeted and personalized customer communications.

The Challenge: 

How do you optimize marketing spend while maintaining high engagement in the competitive travel industry?

Founded in 2003, sonnenklar.TV has established itself as a leading travel shopping channel in Germany. With over 11 million customers and a presence across television, online platforms, and approximately 230 franchise travel agencies, they've built a strong reputation for offering attractive vacation deals.

Despite their success with WhatsApp marketing, sonnenklar.TV was facing significant challenges:

  • Inefficient audience targeting: every campaign was being sent to their entire subscriber base, regardless of engagement levels
  • Rising marketing costs: this broad approach was leading to unnecessary spend on Meta costs
  • Declining engagement rates: inactive subscribers were diluting campaign performance metrics
  • Missed revenue opportunities: without proper segmentation, personalized offers weren't reaching the most receptive audiences

In the highly competitive travel industry, where margins are tight and customer preferences change rapidly, sonnenklar.TV needed a solution that would allow them to communicate more effectively with their audience while optimizing their marketing spend.

 

The Solution: 

Partnering with charles to implement sophisticated audience segmentation strategies that dramatically improved campaign efficiency and effectiveness.

With charles' WhatsApp Marketing platform, sonnenklar.TV transformed their approach to customer communications. Their current strategy includes:

 

1. Acquiring WhatsApp subscribers: sonnenklar.TV leverages strategically placed website CTAs to attract new leads. By offering exclusive discounts and special offers, they encourage customers to opt-in and become part of their WhatsApp community.

Collecting subscribers for their WhatsApp newsletter by offering bargain alerts and access to exclusive deals 

 

2. Collecting zero party data: To create truly personalized experiences, sonnenklar.TV needs deeper insights into their customers' unique preferences and interests. Through an interactive WhatsApp opt-in flow, they gather a double opt-in, along with key data points such as what types of deals subscribers are interested in as well as their email address.

3. Detailed segmentation based on engagement: sonnenklar.TV now targets subscribers with precision. Three out of four monthly campaigns are sent exclusively to users who have engaged with the newsletter, while one campaign per month reaches all subscribers – giving inactive users a chance to re-engage. This strategic shift has significantly reduced newsletter costs and increased engagement.

 

4. Personalized travel offers and promotional campaigns: By analyzing customer behaviour and preferences and using segmentation capabilities in charles, sonnenklar.TV delivers tailored travel recommendations that resonate with individual interests – from beach getaways to city breaks or adventure tours. Their "Mega Wednesday Deals" and other time-sensitive offers directly to customers' phones, create a sense of urgency and drive immediate action.
