The Challenge
In Q4 of 2024, a national social services nonprofit was preparing for the critical holiday fundraising season. Like many organizations, their success hinged on end-of-year giving campaigns, traditionally powered by direct mail. But with donor attention increasingly fragmented, they faced an urgent question:
How do we ensure our mail gets opened—and acted on—before it’s too late?
The Solution
Synergy proposed a simple but powerful addition to their campaign mix: a Broadcast Voice Message.
Each message, 45 seconds or less, was recorded by a familiar leader within the organization—no asks, just thanks. The tone was warm, personal, and focused on donor impact. “Watch your mailbox in the coming days,” the voice would say. “Your support has meant so much.”
By placing these messages just ahead of each mail drop—Thanksgiving, Christmas, and Year-End—Synergy aimed to create awareness, prime donors, build connection, and spark curiosity before the envelope ever arrived.
The Results
The results spoke volumes:
- Thanksgiving Campaign → Response rate lifted 10% with voice broadcast
- Christmas Campaign → Response rate climbed 16%
- Year-End Campaign → Response rate jumped an impressive 27%
Additionally, the average gift rose by $2.50, delivering a meaningful bump in net revenue across all three campaigns.
Even more impressive? These outcomes were achieved without making a direct fundraising ask—keeping the organization in full FCC compliance.
The Transformation
In a crowded season where every message competes for attention, one thing made this nonprofit stand out: a voice.
The voice broadcast didn’t replace direct mail—it amplified it. By speaking to donors before the ask, the organization reminded supporters why their partnership mattered. The result was a seamless donor experience that inspired faster, stronger giving.
With Synergy’s help, this nonprofit proved that people can be moved to action through the personal and passionate sound of someone’s voice.
