Major donations coincide with major events, especially in political.
Explicit solicitations for donations spur more donation activity than newsletters or updates.
Solicitations connected to real-world events are more ef- fective than general-purpose ones.
The effect of (number of friends who are donors to the charity) is by far the greatest: for each friend who donates to a charity, the likelihood for the user to also donate to that charity goes up by 24%.
Our paper provides a unique exploration of the donation behavior of hundreds of thousands of user.
We take a data-driven approach in which we examine the incoming and outgoing emails for these users over the span of two months.
