I have a mailer that is sent out a few times out of the year. I have some people who never update there emails so I get 500 rejection emails returned to me. Anyone have any suggetions on some easy way to export them all to a csv or mysql out of thunderbird. I its 1 email address per email. Any suggestions to speed up the process instead of doing a copy and paste one by one.
Why not having them send to return-to email address and merge all those mails, get a script that will extract all mail addresses and remove them from your listing.
