Which marketing channel has the best ROI for nonprofits?

Direct mail leads on return for nonprofits. The Data and Marketing Association reports a median ROI around 29 percent, and mission-driven mailings often clear that benchmark because donor audiences are warmer than commercial ones.

• Direct mail is the top single channel for return, especially to an existing donor file.
• Email offers the lowest cost per contact, making it efficient for volume.
• Multi-channel beats any one channel alone for both acquisition and retention.

The strongest programs combine print, email, and social so a supporter sees the ask in more than one place before deciding to give.
