Please be cautious when using a company-sponsored email address to receive information from Honor Flight at Dulles. The Spring 2023 Signup notification that went out this morning saw several unsubscribes from business emails including a bunch from one company site. Some business systems automatically filter incoming emails to avoid spam. Getting multiple emails to company employees from one sending address might trigger this unsubscribe action as a spam blocker. Please consider a personal email address when communicating with us.
