PostalAgent – Send Postcards online by circling areas on a Google Map
Hey HN, I just launched https://PostalAgent.com, a site that lets you easily send highly targeted postcards to specific neighborhoods. I originally built this site 5 years ago but shut it down when my full time engineering job became too demanding, but recently I did a full rewrite with many new features.

In plain words
PostalAgent is an online postcard service that lets users send targeted mailings to specific geographic areas and demographics. Users select locations by city, state, or by drawing custom areas on Google Maps, then filter recipients by household income, home value, rental status, and other criteria. The platform also supports business targeting with filters for franchise type and tax code. It is designed for home services businesses, real estate agents, and other companies needing direct mail campaigns to specific neighborhoods or customer segments.

In the maker’s words, at launch
Hey HN, I just launched https://PostalAgent.com, a site that lets you easily send highly targeted postcards to specific neighborhoods. I originally built this site 5 years ago but shut it down when my full time engineering job became too demanding, but recently I did a full rewrite with many new features. To start you can select an area using a City, State, or even by circling specific areas on a Google Map. Then, you can refine your results and filter on specific demographics, like household income, home value, rental status, etc You can also search for Businesses rather than consumers, and even filter by franchise type, presence of email, IRS tax code, Franchise Type, etc. I was able to get a few clients signed up very quickly, mostly home services type businesses and real estate agents, but I think it could be used by many types of businesses. I have a few customers that are only using the mailing list feature without sending postcards, likely for cold email or other marketing outreach. I'm looking for a bit of feedback from the community.
