Sorry to see you got that email. I have no idea of the numbers of applicants or the hours they have. Though the announcement mentions ATP preferred. I would think that with all the retirements coming up, all the airlines will be soon be scrambling for pilots with your time and experience, ATP or not.
Starting 1 Aug 2013, an ATP will be required to be hired by any 121 carrier. http://www.atpflightschool.com/airl.../1500-hour-rule/1500-hour-rule-explained.html
