Mozilla Thunderbird - Multiple Addresses for 1 Individual

Question

I use Mozilla Thunderbird as my default Email client. In my address books I have a few entries of individuals with multiple email addresses. I now address emails to each of their addresses as a separate entry when sending an email. How can I enter more than 1 address in my Thunderbird address book, so that when I enter that individual in the address field of an email all three addresses appear as a single entry? Can this be done? I would sincerely be grateful for any help that any of you could provide.

Answer 1

Create a Mailing List for recipients with multiple email addresses.

• Press CtrlShiftB to show the Address Book dialog.
• Right-click on the preferred location for the entry -- Personal Address Book or Collected Address Book.
• Select New List.
• Add each address for that individual -- Thunderbird helps auto-complete the entry if the individual address exists.
• Give the list a unique, easily-remembered name.

Now, when you add that single address to a To:, Bcc: or Cc: line, all the addresses in the list are included.

Answer 2

When you create a contact, there is a space for "Additional email" - simply enter a comma separated list. When you compose a message and type their name, you can pick to send either to just the primary email in the "Email" field, or all of the "Additional Email" entries.
