Send a system email
Use this function to send important non-marketing emails, such as notifications about updates or service unavailability. System email ignores the "Do not use email" checkbox if it is selected on the Communication channels tab of the recipient’s contact record and sends an email to the contact.
Use system emails to send only service, transaction emails and important customer notifications. Using system emails for marketing purposes might lead to issues with the domain reputation and decrease the email deliverability.
To convert a marketing email to a system email, select the System email checkbox on the Parameters tab when creating a new email (Fig. 1).
By default, the System email checkbox is displayed on the email page. Use the "Enable option "System email" system setting to hide the System email checkbox.
