Propeller is a surety bond platform that simplifies and accelerates the process of buying and managing bonds. With digital-first workflows, instant issuance, and a broker-friendly interface, Propeller empowers insurance agents and agencies to offer bonds more efficiently - without paperwork, phone calls, or delays.
Early success came from inbound traffic and referral-driven sales. But to hit the next phase of growth, Propeller needed a repeatable, scalable outbound engine. That meant building infrastructure that could support high-volume cold outreach - without sacrificing deliverability.
When Danny Goff joined as Director of Sales, he set out to make outbound a core revenue driver.
“Operating in a high-growth startup environment requires speed, scalability, and operational efficiency. We needed to build an outbound motion that didn’t break as we scaled - and Mailforge gave us that foundation.”
Why Propeller Chose Mailforge
The Propeller team needed a cold email infrastructure that could move as fast as their growth targets. Off-the-shelf sending tools weren’t enough - especially given the tightening restrictions around cold outreach from Gmail and Outlook.
The Results
Within just one year, Propeller shifted its growth model to 40% outbound / 60% inbound - a significant strategic transformation.
By year 3, outbound became the dominant channel, responsible for 60% of total lead volume.
This outbound engine played a critical role in Propeller’s expansion from 500 to over 10,000 customers.
“Mailforge helped us build outbound the right way - fast, reliable, and deliverable at scale. It was a key piece of the machine that took us from 500 customers to 10,000+.”
The Takeaway
For sales teams operating in tightly regulated or specialized industries like insurance, cold outreach can be risky without the right infrastructure. Propeller avoided those risks by investing early in Mailforge.
The result: a scalable, compliant, high-performing outbound motion - without the deliverability headaches.
