These sneaky little people get your email through an innocent Home Depot survey...you know when they walk around the store in a Home Depot uniform, asking you to take a 3 question survey...Never mention their company is Rainsoft and they will pester you daily thereafter.

It is a company called enviro tech. They sell home water softening and conditioning supplies. They got my information when a person dressed in a hme depot uniform asked me three questions about water quality at my house.
