Reaching Gen Z with real-time conversations

ETS is constantly evolving how it connects with prospective students. As part of the marketing team, Sara focuses on lead generation during the awareness and consideration stages of the customer journey, ensuring the right information reaches the right audience at the right time.

However, shifting customer preferences, especially among Gen Z audiences, posed a growing challenge. Traditional channels like email were no longer delivering the engagement ETS needed.

The challenge: low engagement with traditional channels

Email marketing had long been ETS’s core communication channel. But over time, the team noticed declining open rates and limited engagement.

Gen Z audiences were expecting faster, more conversational interactions, something email simply couldn’t deliver.

To stay relevant and responsive, ETS needed a channel that enabled instant communication while still supporting scalable marketing efforts.

The solution: WhatsApp marketing powered by SleekFlow

ETS decided to move its customer conversations to WhatsApp using SleekFlow.

With SleekFlow, the team was able to:

• Launch WhatsApp broadcasts to reach leads instantly

• Automate responses using AI to deliver fast, accurate information

• Track performance with analytics to continuously optimize campaigns

By training SleekFlow’s AI agent with key information, ETS ensured customers received consistent and reliable responses without increasing manual workload.

Beyond the platform itself, ETS also valued SleekFlow’s ongoing support. From onboarding to continuous feature updates, the SleekFlow team regularly shared insights on new AI capabilities and performance improvements.

The results: higher engagement, better efficiency

The shift to WhatsApp delivered immediate impact.

• 63% increase in engagement

• Significant improvement in reply rates

• Better time management and operational efficiency

With automation handling repetitive inquiries, the marketing team could focus on strategy while maintaining high-quality customer interactions.

So we've trained the AI agent to gather all the information that we've input into it in order to respond to customers in a fast and accurate information. This helped us with time management and efficiency. We've noticed an increase in engagement for around 63% and a significant increase in reply rates.
