Nonprofits send a lot of emails but only a handful drive the majority of results. At Optimize Consulting, we’ve proven that a **STRONG signer** can dramatically improve donor acquisition and turn even cold emails into high-performing campaigns. And now, we’ve updated our case study with **bonus content** that shows how this strategy scales.

## The Impact of a STRONG Signer

In one example, a prospecting email signed by Senator Ted Cruz brought in 555 new donors—an **880% increase** over the client’s previous best month—and delivered a **13x return on investment**. All from a single email with the right name in the signature line.

In the new update, we share how Kirk Cameron helped launch SkyTree Book Fairs with immediate momentum. His support, paired with smart messaging and targeted outreach, led to over **1,000 new donors**, multiple **five-figure gifts**, and more than **$82,000 raised**—without expensive lead gen.

## Why It Works—and Why It’s Worth It

STRONG signers bring name recognition, credibility, and urgency—especially when your organization is still building awareness. We help clients identify the right person, craft the ask, and deliver high-converting emails that open doors.

## What’s New in the 2025 Update?

You’ll get:

- A second case study featuring **Kirk Cameron & SkyTree**
- Real numbers and results from both campaigns
- Bonus tips on **list rentals vs. revshare**
- A clear framework to help you get started
