Adding a Contact to your Address Book in Thunderbird

Thunderbird includes an address book you can use to store email addresses and other information about people you know.

Add a Contact to Your Address Book

To add a contact to your address book in Thunderbird, do the following:

  1. Open Thunderbird.
  2. Click the Address Book.

2a. You may notice you have two address books: Personal Address Book and Collected Addresses. These address books appear on the left side of the window. Thunderbird adds email addresses to your Collected Addresses as you send new email messages. You should add new contacts to your Personal Address Book.

  1. To add a new contact to your address book, click [Personal Address Book] on the left side of the window.
  2. Click New Contact.

  5. All other fields are optional. You may enter additional information about this person, including phone numbers, postal address, job title, etc.
  6. When you are done, click OK.

You have added a new contact to your personal address book in Thunderbird.

Use Your Address Book

Thunderbird Will Suggest Email Addresses to You

  2. You can type a name, or the beginning of an email address, in the To field, and Thunderbird will display suggestions. To use one of the suggestions, click on the name of the contact you want to send an email to.

View Address Book Sidebar

You can set up Thunderbird to display your address book as a sidebar when you compose new email messages.

  1. Within Thunderbird, click Write to compose a new email message.
  2. Click View and put a check mark next to Contacts Sidebar.
