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

ClassBlast offers a drag-and-drop email builder optimized for small class projects, with no credit card required to start. Students can import contacts from CSV, design campaigns in minutes, and track basic opens/clicks without complex setups. It's priced at student-friendly rates with templates tailored to common assignments like A/B testing or customer surveys.
