Email and SMS campaigns for a solar company
Solar has a database problem disguised as a lead problem. Any installer with three years of history is sitting on hundreds of quoted-and-never-closed homeowners plus every customer already turned on, and almost nobody touches either list more than once a year.
The unclosed proposal list is the cheapest pipeline you own. Those people wanted solar, took a meeting, and stalled for a reason that has probably changed since. A utility rate increase announcement is the best reason to write to them, because it is news rather than a pitch and it arrives with their own bill as proof.
Existing customers are the second list. They buy batteries, panel additions after an EV purchase, monitoring service and panel removal for reroofs. They also refer, which is how the best installers hold acquisition cost down while everyone else bids up the same clicks.
Two weeks in, watch reply volume from the stalled proposal list. That is where the fastest closes come from.
