Mailing List Thunderbird

How do I get a list of all email addresses in my yahoo inbox?
I have 33,0000 emails in my inbox, I haven’t added most people as contacts.
I want to export/download a list of everyone who has ever emailed me and then have that list in an excel file. So then I can email everyone at once if I want to. Plus go through systematically and decide who I want as contacts or not. Maybe another way is to add everyone as contacts first and then export but I can’t see how to do that either. I’ve got yahoo mail plus and thunderbird if that helps.
Hi Angus,
Who’s telling porkies 3 million,3 hundred thousand,contacts
Ok even if you mistakenly added a zero it is still
unbelievable.
Now having a load of contacts that even you think is too much
the best thing to do is delete the lot.And start again with
as you say some real friends.
Lets face it is there any reason for keeping them
I have 32 names in my contact list and still think it is too
much
I would need a secretary to keep in touch with them
So Angus come down to earth and get rid of them.
Have a great day.
