Explore how to build “mailbox money” through passive and semi-passive income streams that expand your patient impact while creating financial sustainability beyond the appointment-based model.
Episode 25
What if your practice could generate revenue while you sleep? In this episode, Brandon Seigel introduces the concept of 'mailbox money', passive and semi-passive income streams that healthcare professionals can build alongside their clinical practice , and explains why diversification isn't just a wealth strategy, it's a patient impact strategy.
Brandon defines mailbox money as revenue that doesn't require your direct, time-for-money input to generate. The opposite of mailbox money is the traditional clinical model: you must be present, you must perform the service, and when you stop, the revenue stops. Mailbox money breaks that equation. It's income that continues to flow from something you've created, packaged, or systematized , without requiring your hands-on participation every time.
He frames this not just as a financial opportunity but as a clinical one. Most practice owners, he argues, are limiting both their income and their patient impact by staying exclusively inside the insurance-reimbursed, appointment-based model. There are patients who need your expertise but can't access it through traditional care , and there are revenue opportunities that don't require you to see one more patient per day.
The mailbox money categories Brandon outlines include: products (supplements, equipment, curated health tools), subscriptions (wellness programs, ongoing education, membership models), digital education (courses, webinars, content libraries), licensing (your clinical protocols or practice systems licensed to other providers), and strategic partnerships (affiliate relationships with aligned wellness brands or services). Each of these can be built alongside your existing practice without disrupting it.
Brandon gives a concrete functional medicine example: a physician who creates a $499/month wellness subscription that includes curated supplements, bi-monthly blood work review, and educational video content. Once built, the subscription generates recurring revenue independent of the physician's appointment schedule. It also deepens the patient relationship and extends the physician's clinical impact beyond the walls of the practice.
His inspiration for this framework is Greg Todd, a physical therapist who built a system to help healthcare professionals diversify their impact and income through exactly these kinds of models. Brandon's message: you don't have to choose between clinical excellence and financial freedom. The practices that build mailbox money alongside their clinical work are the ones that achieve both , and create more sustainable, more impactful businesses in the process.
