In this window you can set a few program related options.
Set field names: SendBlaster allows you to customize the names of the 15 available fields for each address (the E-mail field is highlighted in red since, regardless of its name, it is the field used to send messages and must always contain the recipients’ e-mail addresses). Simply type the new names in the corresponding boxes and click on the Save button.

Warning: After changing field names, the email message composition tags will also change; therefore message text might also need to be modified accordingly.

Appearance: The side panel view can be toggled between a Windows XP style and an Outlook style.
Default encoding for new messages: This option allows you to set the default character encoding used for the composition of new messages.
