Q. Can a kolel, shul or a tzedaka organization increase their email list of contacts by copying the addresses available on line from other similar institutions? Sometimes they may appear on the emails one gets, when they were not hidden by Bcc?
Can you do the above, if no collection of funds is intended, just increasing the teaching of Torah to others?
A. Horav Shlomo Miller's Shlit'a opinion is that since the above is a common practice by many in our days, as long as the institution does not specifically indicate otherwise, if the emails were published and sent, one may copy them, especially if the contacts are used for spreading divrei Torah or doing chessed. (See also question 1011).
