Thunderbird *does* have the ability to manage address books, including the ability to import *.txt, *.csv, and *.tab and LDIF files. It also automatically collects email addresses from incoming email if you configure it to do so. Each email address that you send to gets added to the Personal Address book by default. In any case, here's what I suggest. Export (Address Book->Tools->Export) a personal address book to *.csv or tab delimited format. Here's what my *.csv looks like:: Chad,Walstrom,Chad Walstrom,chewie,chewie at wookimus.net,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, The list of commas are obviously unused fields, which include address, phone numbers, etc. Use this as the template for creating import-able files from Excel. Actually, if you simply try importing a file that contains nothing but an email addresses per line, Thunderbird may be able to figure it out. It's worth an experiment, anyway. Other features to look at: Mailing lists. Again, manage this through Thunderbird's address book application. File->New->Mailing List. Here you create the initial mailing list card. Expand the Personal Address Book Tree. You should see the list on the left. Highlight and drag the addresses you want in the list. Also, remember that you can create multiple address books. That way you can separate your Personal Address Book from let's say your Contacts, Office, and Vendor lists...
