The Send Test Email form is used to send a single email to the email address you enter in the Enter Test Email Address field. By default the email address is pulled from the Reply to Email field in the Email Campaign form but you can change it to any email address you wish.
The OK button will send a copy of the email you created in the Email Campaign form under the Email tab.
The Cancel button will close the form and will not save any changes you have made.
Press F1 or click F1-Help button in the Status bar for help on how to use the Security form.
