The Infrared Processing and Analysis Center (IPAC), located on the campus of the California Institute of Technology, is
NASA's multi-mission data center for infrared astrophysics. Some of IPAC's services include administering data
analysis funding awards to the astronomical community, organizing conferences and workshops, and soliciting and
selecting fellowship and observing proposals. As most of these services are repeated annually or biannually, it becomes
necessary to maintain multiple lists of email contacts associated with each service. MABEL is a PHP/MySQL web
database application designed to facilitate this process. It serves as an address book containing up-to-date contact
information for thousands of recipients. Recipients may be assigned to any number of email lists categorized by IPAC
project and team. Lists may be public (viewable by all project members) or private (viewable only by team members).
MABEL can also be used to send HTML or plain-text emails to multiple lists at once and prevents duplicate emails to a
single recipient. This work was performed at the California Institute of Technology under contract to the National
Aeronautics and Space Administration.
