How to receive notifications on mail when there is a maintenance activity scheduled for cloud sql instance
Hello @bvskarthik,
Welcome to the Google Cloud Community!
For upcoming maintenance notifications. Notifications aren't sent out by default. You have to opt in to maintenance notifications. You have to select a maintenance window before you can receive notifications.
If the above option doesn't work, you can contact Google Cloud Support to further look into your case. Let me know if it helped, thanks!
