I need to round-up every reply-to email address from my boss' Gmail inbox and save them to an excel spreadsheet. She doesn't need names or any other info... just the reply-to addresses. Well over 20,000 emails. Please help!
Now that I'm on-board, she is using MailChimp. Unfortunately, the 3 years preceding me need to be handled...
I did a quick Google search and came up with these instructions: http://smallbusiness.chron.com/extract-email-addresses-gmail-54401.html Have you tried this approach?
