When people leave messages on my blog, WordPress sends a copy of their comment to my email address. This notice includes their email address. I have about 5000 of these messages and I would like to send them an opt-in email.
Does anyone know of a way I can gather all these email addresses into a file so that I can send them an email. I use GetResponse and I know how to upload the email addresses. What I don't know is how to "lift them" into a file that I can then upload into my GetResponse account.
Thanks in advance!
