It is now possible to enable HTML formatting for alerting emails. You can change the outgoing email format of alerting emails to HTML, which will show a basic formatted email and replace plain text links with text with a hyperlink.
To format outgoing alerting emails with HTML, go to the Alerting by email integration in the menu under , select the Customize integration box, go to the Customizations tab, and select Use HTML mail.
Changing from plain text to HTML formatting in alert emails may cause issues with automated systems that use the plain text alerting emails. As a result, this option is not enabled by default for existing accounts, but it is enabled by default for new accounts.
