Hi, I would like to ask someone more experienced to help me with this problem:

I have 2 columns (A & B)

in the A column there is a list of e-mail adresses of subscribers, in the second column there is a list of email adresses of the people who decided to delete their subscription.

I would like to filter the columns, so in the "C" column there will be the list of subscribers from the column A without the people (emails in the B column) who decided to unsubscribe.

Is there any simple way how to achieve that? Thank you. Any help will be appreciated.
