I am filing (using tags) email set to certain people in a specific folder in a Google Apps gmail account. Is there a way to export the email addresses of all the people I've emailed for messages in this folder?
Late reply but might help someone.
We have looked all over for something to do this at folder level, the one we found and use to backup our email addresses was Gmail Email Exporter at www.starbanana.com
It exports email addresses that are contained in the email envelope ie To From etc.. so it doesn't work directly on the your contacts list only the email addresses found in actual email messages.
Its pretty quick but if you have large amounts of emails you may have to export in chunks as Gmail have some hourly/daily?? limits imposed, this caught us out and took a while to discover what was happening.
I am not connected to this company, I Google'd for ages trying to find a program that works with Folders and was shocked that this was the only one at the time. Come on Google this is basic stuff!!!
