How to Import a static list without affecting existing lead base?

[Vincent_Kee]

Hi all, I was wondering how do I import a temporal list of contacts without affecting the existing lead base for a one-time campaign program.

In List Import Mode, you can choose "Skip New People and Updates" and it means that your list import will not impact existing person records or log any activities. If you select this mode, you will skip person field updates and activity logging. Also, it will skip new person creation.

Thanks for the reply! I tried that method but I do want to add new contacts as well in this list but there are names already exist in the lead base. So my main objective is to import a temporal list with new contacts and existing contacts into a program without affecting the lead base.
