The Server Action can be configured to send e-mails. You can find the documentation in this article.
Enter the sender and receiver e-mail, optionally CC and Bcc. You can enter multiple e-mail addresses for the receiver, CC and Bcc – in this case, the e-mail addresses have to be separated with a semicolon. At least, enter the subject and the body in HTML. For better user experience, it is possible to maximize the editor.
It is also possible to use the mapping dialog to this instead of using the settings panel.
Important: If a mapping is set, the settings in the panel are not considered.
