The Opportunity

Problem

Marketing students can't afford or easily use complex email marketing tools like Klaviyo for small-scale class campaigns due to high costs and lack of student discounts or simple interfaces.

Solution

GroupMailr lets student teams co-edit campaigns in real-time, share lists securely, and track shared analytics for class presentations. Built for 2-10 person groups with role-based access and comment threads. Affordable team pricing starts free for small groups.

Target Audience

Students in marketing classes conducting small-scale campaigns

Differentiator
