How do I configure alerts in the SLA policy?

Yes, Vtiger CRM gives you the option to configure email alerts that must be sent before an SLA violation happens.
This is how you must configure the alerts in the SLA policy:

To receive alerts, follow these steps:

1. Enable the Alerts checkbox in the Set SLA Targets window.
2. In the Configure Email Alerts (before violation) block, configure the following: 
   1. Select the users who must be alerted when the SLA is about to be violated.
   2. Enter when the email alert must be sent before the SLA violation.
   3. Select an email template to send the alert. These email templates are related to cases or internal tickets based on the type of SLA you are creating. To learn more about Email Templates, click here.
