I manage lists for a not-for-profit group. We have an extensive member
database on an excel spreadsheet. I want to emails to a subset of that
spreadsheet. When I use the filter to select the people I want, then save
that list to a new file, I see only the names I want on that new spreasheet.
However, the names skipped over seem to be present in some form because they
all transfer to the csv file and end up in the email list. How can I avoid
this?
