You can change the email notification frequency and other alert settings from the Settings screen:
Click the Gear icon near the top-right corner of the dashboard.
Select the Alerts tab. Change the value in the ALERT EMAILS LIMIT section to change the email limit.
This limit defines the threshold where the system will group alerts into a single email. The system will send this many identical alert emails, and then it will group them together into an email digest. If set to 0, it will send each alert as a separate email.
To learn more about Alert settings, check out the Settings > Alerts section on the Teramind User Guide.
