Mozilla's Thunderbird is a free alternative to the standard mail apps for Windows and Mac. The following instructions will guide you through the step-by-step process of adding a secure IMAP account. This guide was prepared using Windows 7 and Thunderbird version 24, but the process is nearly identical for Mac users, as well as recent versions with the older user interface.
- Account type: IMAP
- Incoming mail server: mail.invisibleink.com
- Outgoing mail server: mail.invisibleink.com
- Username: email@example.com (full email address, all lowercase)
