I am newer to constant contact. I inherited a multiple year contact list broken out by year name. Some years there are most of the the same people and just a few new added to the list each year. We have an annual event I want to invite all of them to. If I send out an email invite to all lists from each year (the whole list) will it send duplicates for each year they were on the list? Or will it selectively recognize that that same address is listed multiple times and just send it to them once? I don't want to miss anyone, yet I don't want send them the same invite for the multiple years they have been involved?
