Automated the process of sending next-day event reminders to every attendee by connecting Google Calendar with Gmail through Make.com.
Watch Project WalkthroughThe challenge
Managing event reminders manually becomes repetitive as the number of attendees grows. An organizer may need to check upcoming events, identify everyone attending and send individual reminders before each event. This creates unnecessary administrative work and increases the chance of someone being overlooked. EventPulse needed a simple way to make this process automatic.
The solution
Built a Make.com automation that runs daily and checks Google Calendar for events scheduled the following day. When an event is found the workflow retrieves the attendee list and uses an Iterator to process each attendee individually. The workflow then sends a reminder email to each person using the event information pulled from Google Calendar.

What I built
The workflow checks Google Calendar for events happening the following day.
Ensures every upcoming event is captured automatically without manual calendar checks.
An Iterator loops through the full attendee list and processes each person individually rather than sending a single notification to only the organizer.
Ensures no attendee is overlooked regardless of event size.
Each attendee receives an individual reminder containing the event name, date and time, location and event specific information.
Consistent professional communication delivered automatically to every person on the list.

Key outcomes
A manual routine of checking upcoming events, identifying every attendee and sending individual reminders that broke down as attendee numbers grew.
A scheduled Make.com scenario that finds next-day Google Calendar events, retrieves the attendee list and uses an Iterator to send each attendee an individual Gmail reminder.
Reminders now run on a schedule instead of on memory. Every attendee receives accurate event details automatically, nobody is overlooked, and the process scales with any attendee list at no extra admin cost.
