You can set the Gmail app up so that when those emails come in, it will automatically create them as events in your calendar.  Not only can you set this up for the web-based version of Google Calendar, but you can also do it for the mobile version as well.  And I’m going to show you how to do just that.

Requirements

The only things needed for this to work are a Google account and the Gmail app installed on your mobile device. This feature works on both Android and iOS but I’ll be demonstrating it on a Pixel 6 Pro that’s running Android 13.  With that said, let’s get to the configuration.

How to enable Show Events from Gmail

With these features enabled, any email you receive in your Gmail account that includes event details should cause that event to be automatically added to your Google Calendar.  Close the Gmail Settings window and you’re done with the web version of Gmail. If you find this has too much impact on your calendar, you can always go back and disable it. But if you like the convenience this automation brings, the feature can come in very handy. I’ve missed several events that were sent via Gmail in the past. With this feature enabled, that no longer happens. And any time an event is automatically added from Gmail that I don’t want on my calendar, I can manually delete it. That trade-off is well worth the small inconvenience that comes with the convenience of automation. Give this feature a try and see if it doesn’t make your mobile life a bit more efficient and reliable.
