Disable alert e-mails from Mail / Calendar [duplicate]

I recently got a Macbook Pro for work, and am pretty new to the platform. One of the annoying things I noticed, is that after I configured all of my Gmail accounts, I started automatically getting these "alert" e-mails for calendar appointments.

I don't want Mail or Calendar to send me alert e-mails, because I already get them directly from Google.

My question is: How can I disable these alert e-mails from occurring?

It is indeed Mac Calendar problem as author of the question suggested.

I faced the same issue and observed that I get these nasty "Alert - ..." emails only when Mac wakes up. I also did not get them before I started using my Mac.

To solve the problem on macOS 10.12.3:

• Open Calendar app
• Find your Google calendar on the list and right mouse click it
• Select "Get Info" option from the context menu
• Mark "Ignore alerts" checkbox in the popup window (see screenshot).
