GReminders

GReminders helps you reclaim your time by automating the tedious process of scheduling and following up with clients. By syncing directly with Google Calendar, Outlook, and Office 365, the platform monitors your schedule and sends automated text, email, or voice reminders to your appointments. You can set up custom sequences that trigger based on specific event types, ensuring your clients always have the information they need to show up on time.

Beyond simple reminders, you can create personalized booking pages that allow clients to schedule meetings based on your real-time availability. This eliminates the back-and-forth of finding a time that works for everyone. Whether you are a solo practitioner or managing a large sales team, the platform provides the tools to reduce no-shows by up to 90% while maintaining a professional image through fully customizable templates.
