Thunderbird Add Notes to Emails Feature

[challenger396]

I would really like to be able to add a note to my emails. As of right now I just leave them unread until they have been follow through with or are completed but being able to add notes would help me keep track so much better. Example notes: Already forwarded to the accountant. Waiting for P&L Report to attach. #thunderbird#

I had a similar need, but not for notes per individual email—rather, notes per sender.

I built an add-on that lets you attach a note to the sender of an email, so the next time you receive a message from the same person the note is shown automatically. I use it to store quick communication context like “cooperative”, “open balance”, etc., so I can immediately remember who I’m dealing with without searching through previous messages.

It won’t replace per-message notes (like labeling individual Amazon orders), but for recurring contacts it’s very useful. If this matches your workflow, I’d love feedback and I’m happy to help anyone set it up:
