Luth: Donations through e-mail don't quite work

According to Luth Research, at least 40% of US households have made financial donations to non-profit organizations from face-to-face interactions or through postal mail. Over 15% have made material donations resulting from a call from someone they knew, while just 4.7% have made such donations based on receiving an e-mail from someone they knew. E-Mails from a known person do better for financial donations, as 8.1% have made monetary donations from such e-mails.
