Overview

An email thread usually carries context that does not belong in the email itself — what you are waiting for, what was agreed on the phone, which project it relates to. Threadmark keeps that context next to the conversation instead of in your head. It works alongside Apple Mail rather than replacing it, and it stays a lightweight companion rather than growing into a CRM.

What it does

  • Context where the conversation is

    Attach a note, a tag or a follow-up date to a thread and find it again from the thread itself.

  • Invisible until needed

    Threadmark complements Apple Mail instead of competing with it. Your mail workflow does not change.

  • Your annotations stay yours

    Notes are private by default and are never sent to anyone in the conversation.

Availability

Threadmark is not yet available. When it is released, this page will link to its official Setapp page.

Notes and metadata are stored locally on your Mac. Email content is not uploaded, and no Threadmark account is required.
