In case you are planning on sending out an e-newsletter over the holidays, make sure you include a link to donate! From the NY Times:

For charities that solicit donations online, Dec. 31 is more than New Year’s Eve — it is the most lucrative day of the year.

New data from Convio, a software company, shows that charitable donors that use Convio’s online giving systems made 13.2 times more gifts last Dec. 31 than the daily average for the rest of 2008, and that the charities raised 22.5 times more money than they did on an average day.

Convio, which estimates that as much as 10 percent of online giving moves over its systems, also found that in the last week of 2008, the average gift size was 57 percent larger than the weekly average for the rest of the year.

“The bottom line is that the last week of the year and, in particular, the last day of the year, is huge for online fund-raising,” said Gene Austin, Convio’s chief executive.
