Database reactivation is running campaigns against a contractor's existing CRM records, old quotes that never closed and past customers due for more work, rather than buying new traffic.
These are contacts you already paid to acquire once. They are usually the cheapest booked jobs available in any given quarter and most contractors never touch them.
The economics are not close. Cold advertising pays to build trust from zero; a database already has it, so the same crew and the same trucks get filled at a fraction of the acquisition cost. The money was spent years ago and the asset has been sitting there depreciating.
The two segments want different messages. An old unclosed quote needs a fresh number, because the one they sat on is stale anyway and most of those homeowners never said no, they said not yet and then nobody called again. A past customer needs a next-project nudge for the adjacent job: the window customer with a bathroom on the list, the roof customer who needs gutters.
The reason almost nobody runs it is not skepticism, it is that no system owns it. Numbers go stale, contacts live across three tools, and pressing send is nobody's job. Quarterly is the cadence that works: often enough that no record sits a full year without a touch, rare enough that the list does not burn out.
