Problem
Professionals and individuals often struggle to remember timely follow-ups, leading to missed opportunities, stalled deals, and neglected relationships. Traditional task management tools require manual data entry and separate check-ins, creating friction that causes important communications to fall through the cracks.
Solution
FollowUpThen provides a simple email-based reminder system where users schedule follow-ups by placing a date before the "@" sign in the recipient address (e.g., 3days@followupthen.com). The service works with any email program, requires no inbox connection, and keeps data private and encrypted. Users can forward emails to future moments, set private or group reminders, and manage everything through a web app. Add-on "Skills" transform the basic reminder into a personal assistant, enabling recurring follow-ups, response detection, auto-cancellation, SMS notifications, and integration with thousands of apps via Zapier.
Target Audience
Primary users are sales professionals, project managers, and busy individuals who need reliable, low-friction follow-up reminders integrated into their existing email workflow.
Features
- Date-based email addressing: schedule reminders by typing natural language dates before the "@" sign (e.g., "mar30@followupthen.com" or "3d@fut.io")
