FollowUpThen is a simple, email-based reminder and follow-up service created by a small, independent team. Its core feature is scheduling reminders for yourself or others by simply sending an email to a specific time-based address (e.g., `tomorrow@followupthen.com`). It's primarily built for busy professionals, salespersons, and anyone needing a lightweight, frictionless way to ensure tasks and communications don't fall through the cracks. Users activate it when they need to remember to follow up on an email, revisit a task, or remind someone else about an upcoming deadline. It works with any email client or platform, as it's purely email-driven, requiring no specific integrations beyond your existing email account.
Why It’s Useful
It replaces complex CRM follow-up systems or manual calendar entries, offering a dead-simple, email-native way to schedule reminders that is far less intrusive than Boomerang for Gmail for specific tasks. Its simplicity is its strength. For the salesperson waiting on a client's response, they can BCC `3days@followupthen.com` on their outgoing email, and if no reply comes, the original email will reappear in their inbox as a reminder. For the project lead who needs to revisit a task next Monday, they can send an email to `nextmonday@followupthen.com` with task details, and it will resurface at the right time. FollowUpThen offers a generous free tier for basic usage, with paid plans unlocking more reminders, advanced recurrence, and shared reminders for teams. A less-known feature is the ability to create public URLs for reminders, allowing others to quickly set a reminder for themselves or a group with pre-filled content. It's not more popular because its email-based interface, while powerful, might seem counter-intuitive to users accustomed to graphical UIs, and it lacks aggressive marketing. The service has been consistently maintained for over a decade, receiving regular bug fixes and minor feature enhancements, ensuring reliability without a large community.
