Add a smart reply feature to Thunderbird that suggests automatic responses based on the content of the received email, with fully customizable templates depending on the context (work, personal, support, etc.).
When an email is opened, Thunderbird analyzes its content locally (privacy-respecting).
It then suggests 2โ3 pre-written replies that the user can send with a single click.
Users can create and manage their own templates with simple rules, for example:
If the sender is in the โworkโ group, suggest: "Thanks for your message, Iโll get back to you later today."
If the email contains the keyword โinvoice,โ suggest: "Thanks for sending this over, I've received it."
A template editor with condition-based logic (sender, keywords, priority, etc.).
Smart variable insertion (e.g., contactโs name, date, subjectโฆ).
Works across multiple accounts.
Optional auto-reply with user confirmation.
Huge time-saver for professionals, nonprofits, and heavy email users.
Reduces inbox anxiety and helps process routine emails faster.
Especially helpful for users with writing or typing difficulties.
All processing would happen locally, with no data sent externally โ fully aligned with Thunderbirdโs privacy-first philosophy.
