Keep the folder structure you already use
Clients, jobs, matters, deals, and reference folders stay exactly where you already use them.
How MailLedger works

Why it works
Four principles behind the workflow.
Let real filing sharpen suggestions
Sender, subject, thread history, and corrections improve accuracy over time.
Keep outgoing mail in the same story
Send & File keeps replies with the folder so the record stays complete.
Export when the thread has to travel
Pro packages the folder into PDF or CSV for legal, finance, leadership, or the client.
How it works

Less admin. Faster retrieval. Stronger records.
File email where it belongs

Keep sent mail in the same record
Send & File keeps replies in the same timeline.
Find the right folder fast
Search by project, client, deal, or matter instead of digging through Outlook trees.
