I will be uploading a new list of email addresses into our system.
I have two csv files, both lists of emails and their attributes. The first is the main list and the second is a list of email I need to filter out of the first list.

How do I create a excel csv file that contains a new list that is the original with the second list filtered out.

thanks

What do you mean by filtered out?  Do you want all emails from the original lists and just new emails from the second list?

Import them into access as two different tables. Thenthere are easy ways to combine them like:
insert into table1 select * from table2 where email not in (select email from table1)

If you're looking for the unique values from both lists combined, then use an autofilter.

See this article on how to use the Unique Auto Filter feature:
