Ok, so I have created a contact group and uploaded my contacts, sent an email, and set bounces to inactive. The website where I get my leads from is updated often (making for a very large list). Currently, there are 65k contacts listed and each week they add an additional 10k. There are no filed parameters that allow me to sort out the new contacts from the old. My thought was to download the contacts and upload to Interspire (with the option to update the record). If email@example.com is a bounce from the first import and I download it again the second time, though the email is inactive, will importing it again set the email to active? Basically, I need something that will allow me to extract the differences between the two .csv files as those will be the new records. I look forward to your input and it is good to be back. PS - This question was originally posted in a section that offered no assistance.
