Sure thing, to start off with: council district. One can enter their address here on this map to find their district: https://council.nyc.gov/map-widget/

On the map the results will show your councilperson and a direct link to your district's website (every district has one) that includes information on your councilperson and how to contact their office. All council emails are generally "District#@council.nyc.gov" (replace # with your number). This is the constituent email for residents of the districts to email questions, concerns, etc. and a member of the councilperson's team should get back to you.

A similar process can be followed for New York State Assemblymen and State Senator Districts. These are who represent you in the state government, not to be confused with federal level congresspersons and senators that go to DC.
