Your opportunity: win back existing customers, profitably

Sound familiar? Your existing customers barely open your email newsletters anymore, and your conversion rates are flat or even falling. Yet your current customers hold enormous potential. AI-powered phone campaigns can be the game changer here.

Why phone campaigns to existing customers come out ahead

The average open rate for email newsletters often sits just above 20%. A direct phone call from a local number, or from a number already saved in the customer's contacts, gets "open rates" close to 100%. A 2015 study by Adobe confirms that direct channels like text messages or phone calls achieve much higher engagement than email.

Real-world example: a small business sharply grows revenue

A mid-sized financial advisory firm had long struggled with weak response to its monthly newsletter (open rate around 18%, conversion rate under 2%). After it launched an AI-powered phone campaign that reached existing customers personally with tailored offers, the results were remarkable: the conversion rate climbed to 15%, and monthly revenue grew by more than 30% within a single quarter.

4 big advantages of AI-powered phone campaigns

1. Maximum attention People almost always notice a phone call – nothing disappears unread in a spam folder.

2. Stronger personal relationships Real conversations build trust and strengthen customer loyalty over the long term.

3. Instant customer feedback Concerns and questions get answered on the spot, which makes customers far more willing to decide.

4. Efficient use of resources AI pre-selects your contacts, so you only call the most promising ones – maximizing efficiency and savings.

How to run phone campaigns the right way

  • Define your target groups precisely: AI helps you segment your customers and spot the offers that matter to them.
  • Train your staff: Make sure your team is well prepared for the calls – friendly, knowledgeable and focused.
  • Get the timing right: Use AI-based tools to find the best time to reach each customer.
  • Respect data protection: Follow the applicable data protection rules to keep your customers' trust and avoid legal risk.
