You can specify users in your organization to receive an email notification when they invoke Apex code that surpasses 50% of allocated governor limits. Only per-request limits are checked for sending email warnings; per-org limits like concurrent long-running requests are not checked. These email notifications do not count against the daily single email limit.
System-generated emails from an unverified email-sending domain aren’t delivered, even if the From email address is verified. See Requirements to Send Email from Salesforce.
Important
Log in to Salesforce as an administrator user.
From Setup, enter Users in the Quick Find box, then select Users.

Only users with Author Apex permission can receive email notifications.
