- Mozilla faces Gmail, Microsoft 365 with a range of new features
- Thunderbird Pro includes an appointment, Send and Thundermail
- A new AI writing tool has also come with local treatment
Mozilla transforms his Open Source Thunderbird email client into a complete communication platform with the launch of Thundermail and Thunderbird Pro.
The expansion of Mozilla’s messaging services aims to compete with rival ecosystems like Gmail and Microsoft 365, which are richer in functionality, except Mozilla’s offer is distinguished by its open source of confidentiality, freedom, transparency and respect for users.
“Thunderbird loses users every day against rich ecosystems that are both customers and services,” confirmed Ryan Sipes, director general of the Thunderbird product, expressing the `why ” behind the expansion of Thunderbird.
Thunderbird is about to obtain a redesign
The Thunderbird database indicates that its number of active monthly installations increased from 17.7 million at the end of December 2020 to 16.2 million at the end of March 2025, the messaging application has trouble following the main players in the industry as Gmail.
With the launch of Thunderbird Pro, Mozilla adds the Thunderbird meeting, a new planning tool to share calendar links; Thunderbird Send, a reconstruction of the sending of abandoned Firefox; And Thunderbird Assist, a new writing tool fueled by AI activated via a partnership with Flower AI which is intended to carry out locally to eliminate confidentiality problems.
The final launch will be Thundermail, an e-mail accommodation service using the open source pillar battery. They can choose between thundermail.com and tb.pro.
In addition to coherent community contributors who will be able to obtain early access for free, the SIPS have confirmed that Mozilla would end up invoking functionality, such as sending that requires storage, costly goods.
“Once we have a solid user base for the services to seem durable, we will open free levels with limitations, such as less storage or similar,” added SIPES.
