Why email marketing needs artificial intelligence?
Email marketing remains one of the most effective channels for communicating with your customers, with an average ROI of $42 for every dollar invested. However, creating personalized, consistent, and engaging campaigns requires a tremendous amount of time and expertise. This is where artificial intelligence comes in.
AI agents like Lena can analyze customer data, write personalized content, optimize email subjects, schedule sends at the most opportune times, and analyze performance—all in a matter of seconds. This intelligent automation allows marketing teams to focus on strategy rather than execution.

Unlike traditional automation tools, Lena brings a truly intelligent dimension to your email campaigns. She doesn't just follow pre-programmed scenarios but understands context, adapts tone and content according to the target audience, and continuously learns from previous interactions to improve her performance.
