mail solicitation

Sara O’Hara, 26, and her husband, Brandon O’Hara, 24, accepted a 12-month deferred-interest mail solicitation from Discover in 2013, as they were planning their wedding.

When he received a mail solicitation from the Legal Defense Fund, he donated $5.

On Friday, Mr. Paul’s campaign denied reports that he had written a direct mail solicitation in the 1990s that referred to a “coming race war in our big cities” and mentioned a “federal-homosexual cover-up on AIDS.”

The Web site for Causes says that the 4.75 percent fee is “equal to or greater than” what nonprofits pay themselves in credit card processing fees and compares its cost-effectiveness to that of direct mail solicitation.

This reform knocks out the influence of a relatively few wealthy donors, but forces the candidates to turn to massive mail solicitation in the search for many small donations.
