I have a Yahoo email account that I do not use much anymore. I have subscribed to a number of list servers that send daily email to that account. Over time (years) a huge number of unread emails have accumulated from these list servers.
Is there a way for me to delete unread email from a particular address, i.e., from a particular sender?
I know I can delete all email from a particular sender, but that is not what I wish to do. Ideally I could delete only unread email from a particular sender.
One way would be to select all email from a sender and then scroll through and uncheck those I wish to keep. However, that could take quite a bit of time. Is there a way to automate that process?
Alternatively, is there a way to automate deletion of all email from a particular sender after a particular date or between two dates?
