Advenix just released VisualSubject, a graphical “billboard” that drops down from the email subject line.
(To see how it works, visit http://www.advenix.com/visualsubject.)
Is it an interesting application, providing graphical information in the subject line to help the email stand out from the clutter or a possible new way for spammers to drop undesired content in your mailbox?
Would you use it? What is your opinion?
