Dynamic Signatures & Multi-Profile Signature Management

[tfranzo]

💡 Idea:

Improve Thunderbird’s signature system by allowing multiple, context-aware signatures per account — automatically selected based on rules or email context.

🧠 How it works:

• 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., “Available until 6 PM” or “On vacation until April 4”)

✅ Benefits:

• 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.

📦 Bonus features (optional but useful):

• Shared signature templates across accounts or teams.

• Cloud sync for signatures (optional).

• Preview signature before sending.

🔐 Privacy-friendly:

• All logic should run locally, with no data sent to external servers — fully aligned with Thunderbird’s privacy-first philosophy.
