I set up Thunderbird on both my Windows workstation and Linux Mint laptop to consolidate and streamline how I manage multiple Gmail accounts and project inboxes.

What I configured:

• Unified Inbox across four Gmail accounts
• IMAP setup with OAuth2 or App Passwords for secure access
• Project-specific filters and tags for visibility without moving messages
• Color-coded tags: Finance and Projects stand out in the unified view
• Thunderbird columns customized to show tags in the inbox

Why this works:

This setup gives me offline access, local backups, and high visibility into project-related or financial emails, all without tab-juggling or account switching. Thunderbird serves as my personal email dashboard while mobile apps (like Outlook and Apple Mail) handle quick replies on the go.

Work email stays on the work laptop, and personal inboxes stay lightweight. This split helps keep focus while ensuring I never miss important alerts or project messages.

Bonus: I skipped installation on my Debian HA machine to keep it clean and focused on automation tasks.
