Gammadyne Mailer allows you to build custom user interfaces that can be used to influence the entire mailing.  These custom windows can contain any arrangement of text, checkboxes, editboxes, and buttons.  The possible uses for this feature are limitless.  Remind the user what they need to do before the mailing is sent.  Allow the user to enter a piece of text that is added to every message.  Allow the user to specify a subset of the recipients that the mailing should go to, based on database data.  If you can think it up, Gammadyne Mailer can probably do it!

Following are some screenshots of Dynamic Interfaces built with Gammadyne Mailer:

Please consult Gammadyne Mailer's help file to see the G-Merge scripts necessary to implement these examples.
