Mozilla launching "Thundermail" email service to take on Gmail, Microsoft 365

Mozilla is expanding its Thunderbird email client into a full communications platform with the launch of Thundermail and Thunderbird Pro. This new initiative aims to compete with Gmail and Microsoft 365, offering features like Appointment scheduling, Send file transfers, and an AI writing tool that processes data locally for privacy. Thundermail will be built on the open-source Stalwart stack and offer email hosting with thundermail.com and tb.pro domains. Initial access will be free for community contributors, but costs may apply for storage-intensive features.
