Currently in an early-access phase, the service invites waitlisted users to test its features. This initiative aims to complement the existing desktop mail application while establishing a new revenue stream for the organization through paid subscription tiers. ## Service Features and Storage Subscribers receive an inbox supporting up to 15 email addresses and three custom domains. The package includes 30 GB of mail storage and 60 GB for Thunderbird Send, an end-to-end encrypted file-sharing tool. These features are designed to provide a robust alternative to standard free email providers while maintaining user privacy standards. ## Subscription Pricing and Strategy Thundermail is positioned as a paid service, contrasting with free offerings from competitors like Gmail or Outlook. Early access pricing is approximately £55 annually, with sign-up screens indicating a standard rate of $6 per month. This model targets users seeking an ad-free experience, unlike major free providers that monetize via targeted advertising. ## Platform Compatibility and Access The service features a web-based interface while remaining accessible through the Thunderbird desktop app and the Android mobile client. It also supports integration with other compatible email clients. This multi-platform approach ensures that users can manage their accounts seamlessly across different devices, maintaining consistency in their workflow and communication management tools. ## Interface and User Experience The web interface offers a clean, partitioned layout reminiscent of Gmail, featuring folders on the left and a message pane on the right. Standard functionalities such as scheduling delivery times, managing multiple drafts, and organizing contact lists are included. The system is designed to be intuitive, providing a familiar environment for new users. ## Development and Release Timeline While early access is currently underway, a full public launch is anticipated for 2026. The project previously operated under the Thunderbird Pro banner, encompassing broader services like appointment scheduling. Mozilla has not yet provided a specific date for the general release, but the current testing phase suggests steady progress toward that goal. ## Broader Mozilla Ecosystem Context This development follows recent shifts in Mozilla’s operational strategy, including a move to a fortnightly release schedule for both Firefox and the Thunderbird client. Additionally, Thunderbird recently gained support for Microsoft Exchange late last year. These updates reflect a concerted effort to modernize the platform’s capabilities and improve its overall market competitiveness. ## Market Impact and Outlook By introducing a paid, ad-free email service, Mozilla is testing the willingness of its user base to support the project financially. The success of Thundermail will depend on its ability to offer distinct value compared to established free services. Future updates will likely clarify the final pricing structure and feature set for users. ## Sources covering this story - https://www.theregister.com/software/2026/11/10/mozilla-thunderbird-email-service-edges-closer-to-launch-with-early-access/5308826 — --- _Summary written by Brifing from the original reporting.
