Why Your Agency Doesn't Have a Lead Problem w/ Bart Mroz & Nathan Klug

Bart talks with Nathan Klug about why most agencies and service businesses do not have a lead problem—they have a follow-up problem. Nathan explains how dormant contact lists, if managed and reactivated properly, can produce meaningful revenue without buying more leads. They cover list quality, database reactivation, personalization, and why human judgment still matters even when using AI and software to speed up research and outreach. Key topics In this episode, Nathan Klug argues that most businesses already have enough contacts to create new revenue if they stop ignoring their existing list. He says the average business he sees has roughly 500 to 1,000 contacts, and many of those people have never been followed up with after the initial sale or inquiry. Nathan explains why he focuses on professional and home services: these businesses usually require a real relationship and some pre-sale conversation, which makes follow-up especially valuable. He shares a typical revival rate of about 20% to 30% on reactivated lists, with database reactivation often producing immediate conversations from dormant contacts. Bart and Nathan walk through the math: even a conservative 10% reactivation on a 1,000-name list can create 100 responses, and if 10% of those buy, that can mean real revenue with very little cost. Nathan says every business should do some form of database reactivation at least quarterly with a specific offer, rather than waiting for new lead flow. The biggest operational failure is lack of a data management SOP—not having a consistent way to capture names, emails, phone numbers, notes, and project details. Nathan stresses that the first step is not software, but data quality and structure—a spreadsheet is enough if the information is accurate and organized. They discuss personalization and why generic blast messaging fails. Nathan recommends messages with a simple structure: who you are, why you are reaching out, and a clear call to action. Nathan says AI can speed up research and drafting, but a human should still review both the input and the output to make sure the message feels real and on-brand. He recommends starting small, testing with 20, 50, or 100 contacts before scaling, so deliverability and response rates can be monitored without damaging domains or sending bad messages. For agency owners, Nathan suggests the first move is to analyze 10 old contacts, inspect what data exists, and then send a few targeted messages to see what kind of response they get.
