Go to Settings → Notifications.
Find the notification you want to change and click Configure.
Under Team members, choose who should receive the notification.
Under When to send, choose:
As soon as it happens
Collected into one email on a schedule
Don't send an email
To stop receiving emails for that notification, select Don't send an email.
Click Submit to save your changes.
Note:
Turning off the email doesn't remove the notification from your account. Notifications will still appear under the bell icon in the top bar of the dashboard, so you can review them there when needed.
Also, if specific team members are selected as recipients, they replace the default recipients. Until recipients are selected, emails are sent to the account email address and all admins.
