upload my own list of names with address
I have a list of prospects that I want to upload so I can obtain Home value and auto vin information and then take that data and put it in Quote Burst to run accurate quotes. This will allow me to then send direct mail with the new updated information. So how can I upload a list into SG so I can use a specific list of names? it is a list of 55600 names so I cant do in manually.
