Improve Thunderbirdโs signature system by allowing multiple, context-aware signatures per account โ automatically selected based on rules or email context.
Let users create multiple signatures for each account.
Add rules/conditions to apply the right signature automatically:
Based on recipient domain (e.g., @company.com)
Based on keywords in subject or body
Based on time or day of the week
Based on folder or tag (e.g., replies from a "Support" folder use a support signature)
Support dynamic variables inside signatures:
{{FirstName}}, {{LastName}} of recipient
Current date/time
Conditional phrases (e.g., โAvailable until 6 PMโ or โOn vacation until April 4โ)
Great for users who manage multiple roles, clients, or identities (e.g., freelance, personal, business).
Saves time and ensures more consistent and professional communication.
Useful for teams needing legal disclaimers, branded footers, or different languages.
Shared signature templates across accounts or teams.
Cloud sync for signatures (optional).
Preview signature before sending.
All logic should run locally, with no data sent to external servers โ fully aligned with Thunderbirdโs privacy-first philosophy.
