The release included an updated user interface that focused on a single inbox rather than multiple inboxes.

In January, a new 6.000 release went out to the Play Store, a move that surpised many users. As of today, it’s listed as having 5M+ downloads on Google Play," Cornwall said.ĭevelopment of K-9, however, stalled and the code was basically in "maintenance mode," he noted. About ten years ago it was among the most recommended third-party email clients for Android, and a lot of long-time users have stuck with it. "K-9 was one of the first third-party email clients on Android, and it developed a large user base among users who had to keep track of multiple inboxes. The feature is expected to be implemented in the summer of 2023.Īndrew Cornwall, a senior analyst with research firm Forrester, called the K-9 Mail annoucement "significant." Mozilla plans to offer Firefox Sync as one option to allow users to securely sync accounts between Thunderbird and K-9. "In other words, K-9 Mail will soar to greater heights with the help of Thunderbird.” Ryan Lee Sipes, Thunderbird Product Manager, said working with the Thunderbird email team to develop the new mobile client made more sense than developing a mobile client from scratch. “Joining the Thunderbird family allows K-9 to become more sustainable and gives us the resources to implement long-requested features and fixes that our users want," Sipes said. Currently, Android mobile users have a number of email and chat options, including Google’s Gmail, Microsoft Outlook, and ProtonMail, an end-to-end encrypted email service.
