Mozilla unveils its Gmail challenger — Thundermail

Mozilla has decided to launch a challenger to Gmail called Thundermail. The upstart is a web-based email service based on the open-source project Stalwart, according to technology site Thurrott.

The plan is to eventually add support for calendar and contacts to Thundermail, but when that would happen remains to be seen.

Alongside the new email service, Mozilla is also launching Thunderbird Pro. It offers, among other things, an AI assistant, a file-sharing tool and a planning tool and can be seen as a complement to Thundermail.

Users interested in trying the new services, can sign up for a waiting list at Thundermail.com.
