Spirit Airlines, a discount airline based in Miami, is sending bulk email to an email address that was closed in 2008. Spirit Airlines may not confirm web form subscriptions (which allows typoed and forged email addresses to be added to its list), may ignore bounces (which allows old/closed email addresses to remain on a list), or may have purchased a list. The ESP is Yesmail, a division of InfoGroup.
