Here's the core idea: the best person to get your postcard is someone who lives near a job you just did and has a home like the one you just worked on.
Tell Quillus where the job was — an address or a point on the map. That's the center.
Quillus finds the homes around it that are the best fit and builds your mailing list for you. No buying lists, no spreadsheets, no guessing.
Want to hit the closest 50 homes? The closest 200? You decide how many neighbors to reach. A bigger circle reaches more people; a tighter circle keeps it to the houses most like the one you just worked on.
For realtors: this is neighborhood farming made simple — just sold or just listed a home? Mail the street around it while the news is fresh.
Tip: start tighter and go wider on the neighborhoods that respond. Your results will show you where the interest is.
